Polyethylene pipe performance advantages: ultra high molecular weight polyethylene pipe price is more moderate. Shaanxi high molecular weight polyethylene medium-diameter pipes, medium and low pressure pipeline total project cost even lower than seamless high molecular weight polyethylene pipe, even lower than the composite tube and alloy pipes, but life is higher than six times more than steel, Guangdong composite pipe more than four times the high molecular weight polyethylene pipe, very significant economic benefits. Ultra-high molecular weight polyethylene pipe is a molecular weight greater than 2.5 million high molecular polyethylene wear pipeline, including a polymer of high wear elbow, wear three, four. Ultrahigh molecular weight polyethylene (UHMWPE) is engineering thermoplastics from ethylene, butadiene monomer in the catalyst, the polymerization of viscosity average molecular weight greater than 2.5 million.
