Steel-lined ultra-high molecular weight polyethylene tee/elbow.
Ultra-high molecular weight polyethylene (UHMWPE) wear-resistant pipe fittings include elbows, tees, and various special-shaped fittings. The company can manufacture custom fittings according to the specific requirements of enterprises. These pipe fittings are made from UHMWPE resin with a molecular weight of over 2 million, continuously extruded to form the fittings. They are suitable for medium transmission in special industrial enterprises such as mining, electricity, coal, and chemicals. The superior performance of these UHMWPE pipe fittings is primarily reflected in the following characteristics:High Wear Resistance: The wear resistance of UHMWPE is 4-7 times that of steel pipes, 3 times that of ordinary PE pipes, and 4 times that of nylon. Practical applications have proven that UHMWPE pipes are commonly used as wear-resistant pipes for transporting slurry with small particles.High Corrosion Resistance: UHMWPE has a saturated molecular structure, providing excellent chemical stability. It can resist corrosion from various corrosive media and organic solvents.High Flexibility: The elongation at break can reach over 400%. During construction, the pipe can undergo significant bending. Even when extended up to three times its original length during ground subsidence, it will not break.High Impact Resistance: UHMWPE has the highest impact strength among all plastics, 10 times that of high-density polyethylene and 6 times that of nylon. Whether subjected to strong external impacts or internal pressure fluctuations, it is difficult to crack.Low-Temperature Resistance: UHMWPE performs excellently at low temperatures. At -40°C, its impact strength remains high. It retains good performance even at extremely low temperatures, making it especially suitable for medium transmission in cold regions.Resistance to Scaling: The inner and outer surfaces of the pipes are smooth, with excellent non-stick properties and self-lubricating characteristics. Scaling substances are difficult to deposit and adhere, significantly reducing the cost of pipe descaling maintenance.Anti-Aging Properties: UHMWPE has superior anti-aging properties compared to PE100. When buried underground for 50 years, its mechanical properties only decrease by 20%.Energy-Saving Effect: The friction coefficient of UHMWPE is 0.07-0.11, and its roughness is only 1/6 of that of new steel pipes. The flow capacity exceeds that of steel pipes by more than 50%, and its inner diameter can be reduced by about 15% compared to steel pipes.Safety and Environmental Friendliness: UHMWPE is non-toxic and odorless, meeting national standards for drinking water pipeline use.Ease of Installation: The weight of UHMWPE pipes is only one-eighth that of steel pipes, greatly reducing installation costs. The pipe connection can be made by directly flaring the pipe body and flange docking, without the need for additional seals. It can also be connected by socketed electric fusion welding, offering high joint strength and easy operation.Technical Specifications:Product Name: Ultra-high Molecular Weight Polyethylene Wear-resistant Pipe FittingsTesting Standard: QB/T 2668.1-2017Test ItemStandardTest ResultConclusionTensile Strength≥25MPa30.8 MPaPassElongation at Break≥280%457.67%PassCharpy Impact Strength≥130 KJ/m²145.5 KJ/m²PassSand Abrasion Rate≤0.3%0.14%PassStatic Hydrostatic Test (100h)No cracking, no leakageNo cracking, no leakagePassApplications:Oil, natural gas, crude oil, and liquid transportationUnderground filling and tailings transportationPulp, chemicals, and food industry applicationsMining, metallurgy, and power industry pipelinesEnvironmental protection and wastewater treatment systemsThe ultra-high molecular weight polyethylene wear-resistant pipe fittings, with their superior wear resistance, corrosion resistance, high pressure resistance, and low-temperature performance, are ideal for use in harsh environments.
