Ultra-high-molecular-weight polyethylene (PE-UHMW) pipes
Product profile:
Ultra-high molecular weight polyethylene (UHMWPE) (UPE) pipe is continuously extruded by ultra-high molecular weight polyethylene (UHMWPE) resin with molecular weight more than 2.5 million.
UHMWPE pipe is suitable for mining, electric power, coal, chemical industry and other special mining enterprises.
The advantages :
High wear resistance: 4 times of steel pipe, 3 times of ordinary PE pipe and 4 times of nylon. It has been proved that UHMWPE pipeline is a common wear-resistant pipeline for small particle slurry transportation.
High corrosion resistance: ultra-high molecular weight polyethylene (UHMWPE) has saturated molecular structure, high chemical stability and resistance to various corrosive media and organic solvents.
High flexibility: the elongation at break can reach more than 400%, there is a large bending in the construction, and the crustal subsidence can be elongated to 3 times no fracture.
High impact resistance: the impact strength is the highest in all kinds of plastics, which is 10 times higher than that of HDPE and 6 times that of nylon.Whether external strong impact or internal pressure fluctuations, impact, it is difficult to make it crack.
Low temperature resistance: excellent low temperature resistance, at -40 °C, the impact strength reaches a higher value.Good performance can be maintained at very low temperatures, especially suitable for medium transportation in cold areas.
Not easy to scale: smooth inside and outside walls of pipes, excellent non-adhesion and self-lubricating, fouling materials difficult to deposit and attach, greatly saving the cost of pipe descaling maintenance.
Anti-aging: its aging resistance is better than that of PE100, buried for 50 years, and its mechanical properties are reduced by only 20%.
The energy saving effect is good: the friction coefficient is 0.07-0.11, the roughness is only 1 / 6 of the new steel pipe, the circulation capacity is over 50% higher than that of the steel pipe, and the inner diameter of the steel pipe can be reduced by about 15% compared with that of the steel pipe.
Safe and environment-friendly: It is non-toxic and tasteless, and meets the requirements of the national drinking water pipeline.
Installation convenience: UHMWPE pipe weight is 1/8 of steel pipe, greatly reduced installation costs.Direct flanging of pipe body for pipe connection.Flange butt, do not need to add seals; can also be inserted hot-melt welding, high interface strength, easy to operate.
