In previous years, there were always people who responded that the water in the heating was so smelly and smelly, would there be any harmful substances? Is there something wrong with the underground polyurethane insulation pipe? This kind of thing that may endanger people’s health is absolutely nothing. After some investigation, PEX Crimp Fitting manufacturers ( https://www.ppsu-pex-fittings.com/product/f2159-pex-crimp-fitting/ ) finally found the cause of the smelly heating water.
It turns out that the odorant has been added, so don’t worry. This will explain to you what a odorant is and whether it is harmful to human health. Odor agent, also known as "anti-drop water agent", is a neutral and non-corrosive liquid, which will produce garlic smell when mixed with water, which meets the requirements of national security and environmental protection. This kind of heating water will not corrode the heating system and equipment in residents’ homes, but it cannot be used for normal domestic water. The odorant is used to detect whether the polyurethane PEX Expansion Fittings ( https://www.ppsu-pex-fittings.com/product/metric-size-fitting/ ) run, leak, drip, leak, etc. during the heating process, and to prevent users from discharging water privately, destroying the water flow balance, and seriously affecting the heating safety and heating effect. This time you can rest assured that the odorant is not harmful to the human body. If you smell a bad smell, you should check to see if there is any leakage in the heating in your home, and ask the maintenance personnel to repair it in time.

PEX Expansion Fittings has a variety of colors, including red, blue, white, orange, black, and variations of these themes. When choosing a PEX tube, color is not a meaningful criterion.
Instead, the starting point is the presence of an oxygen barrier. PEX with oxygen barrier is used for installation in a closed loop heating system. This type of PEX is red and sometimes blue. PEX is used in drinking water systems without an oxygen barrier. It comes with the required certifications and can be used as a drinking water device. Drinking water PEX is usually red and blue to facilitate the layout of supply lines. Or, when there is no need to distinguish the power cord, it can be white. These colors are only used to help identify the supply line and have nothing to do with the characteristics of the pipe.
PEX-Aluminium-PEX from PEX Crimp Fitting manufacturers ( https://www.ppsu-pex-fittings.com/product/f2159-pex-crimp-fitting/ ) is usually orange. PEX used for wastewater is usually purple.
Gray is the color reserved for another plastic tube, usually made of polybutene. These are no longer used and have different characteristics from PEX tubes.

F1960 Fittings Are Common
2021年3月17日F1960 Fittings ( https://www.ppsu-pex-fittings.com/product/f1960-fitting/ ) is currently the most common pipe material in the home improvement market. It has developed well in recent years and is widely loved by owners. As a green environmental protection pipe, everyone is very concerned about a question: Is the ppr pipe a plastic pipe? As a manufacturer of ppr pipes, the editor of Almighty E will show you the advantages of ppr pipes.
PPR pipe is a kind of polymer material pipe, referred to as random copolymer polypropylene, also called three-type polypropylene. This material is now widely used in blow molding, injection molding, extrusion, film and sheet extrusion processing fields. Water pipes, food packaging materials and daily consumer goods, and our ppr water pipes are formed by extrusion process, which is undoubtedly a kind of plastic product.
What are the advantages of choosing ppr water pipes for home improvement? Why do most owners now choose ppr pipes?
Polypropylene material is an environmentally-friendly material recognized by the country. It is hygienic, healthy and environmentally friendly. It can be used for daily drinking water transportation and provide safe and secure drinking water for household water supply systems.
The ppr water pipe adopts hot-melt connection, and the pipes and fittings are tightly connected, which can ensure no leakage and avoid the toxicity of glue bonding.
The service life of ppr pipe is relatively long. It is produced and used in accordance with the national standard GB/T18742, and the service life can be as long as 50 years, which is the same age as the building.
In addition to the advantages of the above materials, ppr water pipes are relatively cheap, so the cost performance is very high, and the price is within the acceptable range of most families. This is also one of the important reasons why PEX Fittings Wholesale ( https://www.ppsu-pex-fittings.com/ ) can quickly occupy the main force in the market.

Some people think that the floor heating cleaning is very troublesome, so this step is omitted. But in fact, if the floor heating is not cleaned, there will be serious consequences. Professional floor heating pipe manufacturers will explain in detail why PEX Fittings Plastic ( https://www.ppsu-pex-fittings.com/ ) needs to be cleaned regularly, what effects will it have if it is not cleaned, and how often it should be cleaned.
1. Why does the floor heating need to be cleaned?
Now there are two ways of heating in cities: floor heating and traditional heating, so the temperature of the water supply is relatively high (the temperature of the floor heating water supply should be around 55 degrees, and the temperature of the traditional heating water supply is around 85 degrees). As a result, underfloor heating users have higher home temperatures. Some underfloor heating users turn down or close the water supply valve, which makes the water flow in the floor heating pipe slow, forming pipeline deposits, and more likely to cause pipeline embolism, so floor heating needs to be cleaned regularly.
2. What are the effects if the floor heating pipe is not cleaned?
If the floor heating pipe is not cleaned, it will affect your normal use. According to relevant statistics, in the heating process, every 1mm of dirt on the inner wall of the geothermal pipe will reduce the ambient temperature by 6°C, which not only affects the normal temperature, but also causes a waste of energy. Continued use will cause pipeline embolism. The solution can only be solved by removing the ground and replacing the geothermal pipe, which will cause property loss and life inconvenience to the floor heating users.
3. How often should the floor heating pipe be cleaned?
Generally, the floor heating is professionally cleaned once every two years, and the floor heating service life exceeds two heating periods, and regular maintenance and maintenance are required. In some unprofessional geothermal construction, there will be impurities, stones, and cement in the pipeline. Seriously, if the filter is not installed, it is easy to block the geothermal pipeline in a short time.
Four, floor heating cleaning time
It can be cleaned all year round. After the heating is stopped, the dirt, biological sludge, impurities and bacteria formed in the pipeline during the heating period can be timely removed. In order to prevent the formation of deposits in the pipeline and cause pipeline embolism, so that the floor heating pipe cleanly welcomes the next heating period.

How To Weld F1960 Fittings
2021年1月27日It’s the coldest season of the year again. PEX Fittings Wholesale ( https://www.ppsu-pex-fittings.com/ ) due to its cold brittleness, F1960 Fittings requires special attention in winter construction. So today, the high-end home improvement F1960 Fittings brand cleanliness tube will introduce users to how to weld F1960 Fittings in winter? Precautions for PPR pipe hot melting in winter
1. Before construction, pay attention to check whether the two ends of each F1960 Fittings are damaged. If there is any loss, cut off the lost part to ensure that the entire pipe is not lost before use. Due to the characteristics of PPR in winter to prevent damage to the pipe during transportation, if there is damage or uncertainty, reduce the pipe port by about 5cm when installing the pipe. Do not hit the water pipe with a hammer or heavy objects during winter construction to prevent pipe explosion tube.
2. When cutting F1960 Fittings, the cross-section should be flat and vertical, otherwise it will cause insufficient welding. For pipe cutting, use PPR special pipe cutters instead of quick-cutting pipe cutters.
3. In winter, you must pay attention to whether the temperature of the hot melt machine is normal. The temperature cannot be too high or too low. It is best to choose a thick welded joint of the hot melt machine, so that the temperature will be uniform.
4. Due to the cold weather in winter, the cooling speed of F1960 Fittings( https://www.ppsu-pex-fittings.com/product/f1960-fitting/ ) after melting is relatively faster than in summer, so the speed should be faster during operation.

Method Of Pouring Pex Expansion Fittings
2020年12月2日Expansion PEX Plug ( https://www.ppsu-pex-fittings.com/product/metric-size-fitting/metric-size-fitting-plug/ ) thermal expansion and contraction during construction in winter or summer can easily damage the pipes. Therefore, it is necessary to prevent Expansion PEX Plug from longitudinal expansion and contraction. Expansion PEX Plug should be laid in a serpentine shape in the pipe trench, with a slight curved arc, leaving a margin for expansion; and when installing PE pipes, do not install expanders as much as possible or use double coil short pipes instead of expanders. When making Expansion PEX Plug buttresses and town piers, both sides should be simultaneously poured with concrete at one time.
The bottom foundation of Expansion PEX Plug must be cushioned with fine sand and not less than 100 mm. After the Expansion PEX Plug fittings are installed, the 500mm backfill work on both sides and the top of the pipe must be backfilled and compacted, and the backfill compaction coefficient is not less than 95%. When it is installed in hot weather, it should be constructed as far as possible from night to early morning. The atmospheric temperature is low, and the pipeline is properly contracted and then backfilled and joints meet. It must be compacted in layers to prevent large internal stress damage after the pipeline expands and contracts.
Expansion PEX Plug can be divided into two types: PE electric fusion pipe and hot-melt Expansion PEX Plug. The production method of hot-melt Expansion PEX Plug is one-time injection molding by an injection molding machine. The main raw material is high-density polyethylene. The connection method: There are two types of hot melt butt joint and hot melt socket.
PE electrofusion pipe is a kind of plastic Expansion PEX Plug that can be melted to reach the connection by the temperature generated by the current. Due to the price, the amount of hot melt Expansion PEX Plug in engineering applications is more than that of PE electrofusion pipes, but electrofusion pipe fittings play an important and irreplaceable role in engineering and maintenance, especially in construction. The external environment and human factors have less influence, so the reliability is better and it is more popular with users. Especially in the gas pipe engineering, more and more electric fusion pipe fittings are being used.
The choice between PE electrofusion pipe or hot-melt PEX Expansion Fittings ( https://www.ppsu-pex-fittings.com/product/metric-size-fitting/ ) actually depends on the actual requirements. The effect of the two is the same. The price of electro-fusion pipe fittings is high, but the construction is convenient and the external environment is less affected. The construction is more convenient; The price of pipe fittings is low, but it is often affected by the external construction environment. Under harsh construction conditions, the construction progress is slow.

Quality Assurance Of Pex Fittings Wholesale
2020年11月25日F1960 Fittings ( https://www.ppsu-pex-fittings.com/product/f1960-fitting/ ) on the market mainly come in four colors: white, gray, green, and curry. The main reason is that the added color masterbatch is different. It is recommended to buy white F1960 Fittings. This is to prevent profitable manufacturers from using recycled materials to produce PPR pipes, and add color masterbatch to conceal the defects caused by impure raw materials.
Good soft F1960 Fittings, the pipe fittings are not easy to be squeezed and deformed, even if deformed, it will not break, and greatly reduce the amount of joints; it can resist the corrosion of chemical elements in the water, and the smooth inner surface can avoid the formation of scale; the pipe fittings can withstand the normal temperature The water pressure is 45 kg/cm², and the tube’s non-deformation temperature is 112 degrees Celsius
Moreover, F1960 Fittings has a long life and strong anti-aging of pipe fittings, and its normal function mission reaches more than 50 years. The flexibility of the pipe fittings makes the construction very fast, and easy to connect (with a hot melt machine socket connection), safe and reliable. Due to the simple construction, there are no contradictions and influences with other projects, the construction period is shortened, and the construction cost is 60% less than that of copper pipes, which has superior economic efficiency.
The main component of F1960 Fittings is propylene, which is mainly used as a household water supply system. The diameter of PE pipe is much larger than F1960 Fittings, the main chemical molecule is polyethylene. PE is the main pipeline water supply. Under normal circumstances, F1960 Fittings and PE pipes cannot be hot-melt connected, and the inner teeth must be directly connected to the outer teeth. The wall thickness is inconsistent, and the welding strength of the two materials cannot meet the requirements.
After PE is introduced into the room, it is connected with F1960 Fittings. Small pipe diameter adopts metal conversion and large pipe diameter adopts flange conversion. Cast iron pipes and steel pipes adopt flange conversion outdoors, and flanged wells and soft joints are easy to maintain and replace. The correct connection method is to connect with flanges. Small diameter pipes can also be connected with toothed fittings, so that the connection strength can be effectively guaranteed. PEX Fittings Wholesale ( https://www.ppsu-pex-fittings.com/ ) ensures the quality of the project.

Expansion PEX Plug ( https://www.ppsu-pex-fittings.com/product/metric-size-fitting/metric-size-fitting-plug/ ) is based on the original pure PP, adding glass fiber and other additives to increase the use range of materials. Generally speaking, most of the glass fiber reinforced materials are mostly used in the structural parts of the product, which is a kind of structural engineering material.
advantage:
Glass fiber is a high temperature resistant material. Therefore, the heat resistance temperature of reinforced plastic is much higher than before without glass fiber.
Due to the addition of glass fiber, the mutual movement between the polymer chains of the plastic is restricted. Therefore, the shrinkage rate of the reinforced plastic is greatly reduced and the rigidity is greatly improved.
Reinforced plastic will not stress crack, and at the same time, the impact resistance of plastic will be improved a lot.
Glass fiber is a high-strength material, which greatly improves the strength of plastics, such as tensile strength, compression strength, and bending strength.
Due to the addition of glass fiber and other additives, the combustion performance of enhanced PEX Expansion Fittings ( https://www.ppsu-pex-fittings.com/product/metric-size-fitting/ ) is greatly reduced, and flame retardancy becomes difficult.

Pex Expansion Fittings Summer Welding
2020年11月11日With the arrival of summer, with the gradual increase in temperature, what should be paid attention to when welding PEX Expansion Fittings ( https://www.ppsu-pex-fittings.com/product/metric-size-fitting/ )? In addition to welding according to the normal operating procedure, special attention should be paid to changes in the ambient temperature for welding quality. Impact. Based on years of construction experience, Hangzhou Zhenfei Plastic Industry Co., Ltd. reminds all users and construction units to pay attention to the following points in the summer construction of PE wire and cable protection sleeve material:
1. Check whether the parts of the welding machine are working normally, especially pay attention to measuring whether the temperature of the welding machine heating plate is within the standard temperature range (220℃±10℃) before use.
2. The temperature adjustment of the heating plate needs to consider the influence of the surface temperature and ambient temperature on the actual temperature of the heating plate to prevent the actual temperature of the heating plate (surface temperature + ambient temperature + display temperature of the heating plate)> 230°C. When the ambient temperature is above 38℃ and construction is carried out on asphalt roads, the temperature of the heating plate can be adjusted to between 190℃-200℃; when the ambient temperature is below 38℃ and construction is carried out in the field, the temperature of the heating plate can be adjusted to 200℃ -210°C.
3. Check the error rate before pipe butt joint, the error rate shall not be more than 10% of the pipe wall thickness. The misalignment rate exceeding 10% of the wall thickness of the pipe will cause the contact surface of the weld to be smaller than the wall thickness of the pipe, which will affect the welding effect.
4. The heating time is calculated. When all the circles where the end faces of the two pipes are in contact with the heating plate are turned over, the pressure of the welder is removed and the heating time is started. The heating time is calculated by the pipe wall thickness X 10 seconds.
5. After the PEX Cold Expansion Fittings ( https://www.ppsu-pex-fittings.com/product/metric-size-fitting/ ) welding is completed, the pressure will enter the cooling time. The cooling time is calculated by the pipe wall thickness X1min.
6. After the welding is completed, if forced cooling methods such as water cooling or air cooling are used, it will cause the phenomenon of virtual welding at the welding place and affect the welding quality, so natural cooling should be used for cooling.
1. Check whether the parts of the welding machine are working normally, especially pay attention to measuring whether the temperature of the welding machine heating plate is within the standard temperature range (220℃±10℃) before use.
2. The temperature adjustment of the heating plate needs to consider the influence of the surface temperature and ambient temperature on the actual temperature of the heating plate to prevent the actual temperature of the heating plate (surface temperature + ambient temperature + display temperature of the heating plate)> 230°C. When the ambient temperature is above 38℃ and construction is carried out on asphalt roads, the temperature of the heating plate can be adjusted to between 190℃-200℃; when the ambient temperature is below 38℃ and construction is carried out in the field, the temperature of the heating plate can be adjusted to 200℃ -210°C.

PEX Expansion Fittings ( https://www.ppsu-pex-fittings.com/product/metric-size-fitting/ ) are commonly known as expansion pipes, expansion plugs, expanded rubber particles, wall plugs, plastic anchors and many other names. Expansion tube should have appeared before the expansion screw. It evolved from the wooden plug into the current plastic expansion plug. After the test of time and environment, the performance of the expansion tube is far better than that of the wooden plug. In order to reduce the extent of cold shrinkage and thermal expansion, the anti-aging effect must be much better than that of wood materials, and the force is good, and the matching size is convenient and standard. In the special environment requirements such as insulation and humidity, it can exert the maximum fastening force for a long time, which is deeply loved by customers.
The raw material of the expansion pipe is generally soft rubber HDPE (PE for short), which is a kind of thermoplastic resin made by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefin. Polyethylene is non-toxic and tasteless, feels like wax, and has excellent low temperature resistance. Its chemical stability is capable of resisting most acid and alkali corrosion. It is insoluble in general solvents at room temperature, has low water absorption and excellent electrical insulation properties. Or PA6 and PA66 are the trade names of polyamide fibers, and nylon (PA for short), whose basic constituents are injection molding of aliphatic polyamides connected by amide bonds—[NHCO]—. It is characterized by good toughness, not easy to break, and strong bearing capacity. Among them, nylon material is the most widely used variety among the five major engineering plastics.
The style and classification of expansion pipes: The commonly used expansion pipes are straight-through expansion pipes, and two kinds of fish-shaped expansion pipes. With the expansion and demand of market applications, the styles of expansion pipes are becoming more and more extensive, and their functions It is also more obvious; for example, aircraft-type expansion pipes for ceiling gypsum board, and multi-function knotted expansion pipes for hollow walls and hollow bricks.
For the installation of expansion pipes, improper installation will affect the installation effect of the product. When installing an expansion pipe, you should first understand the weight of the items to be installed and the hardness of the installation substrate, and then choose a suitable expansion pipe. If you are installing a heavier object, you should choose a large-size expansion tube. In addition, you can choose a variety of length products according to the installation base material, such as non-concrete, porous bricks, etc., and you need to use multiple sizes and longer ones The expansion tube is used to install the fixed object, and the bearing capacity is determined by the focal length and the focal distance.
Tips for using Expansion PEX Plug ( https://www.ppsu-pex-fittings.com/product/metric-size-fitting/metric-size-fitting-plug/ ):
1. Drill the prefabricated holes with vertical balance at one time to avoid drilling the same hole multiple times;
2. Clean the holes, which can be cleaned with wind or water, etc.; clear the residue left when drilling to reduce the sliding of the expansion tube caused by dust to increase the friction;
3. Avoid repeated use of holes and expansion tubes. Holes used multiple times will be expanded due to expansion when the expansion tube is expanded. If the same hole is used multiple times, it is easy to cause sliding. If the same expansion tube is used multiple times, Causes the expansion tube to break, deform, easily cause the screw to deviate, the fastening force is not good, etc.
