Ultra-high molecular weight polyethylene (UHMWPE) is a thermoplastic with extremely high molecular weight, which has the comprehensive properties of small friction coefficient, low abrasion, excellent chemical resistance, impact resistance, pressure resistance, frost resistance, heat preservation, self-lubricating, scale resistance, etc., and is suitable for slurry transportation in coal mines and underground high-pressure water supply pipes. Oil field, natural gas, oil pipeline. Life supply and drainage pipes, power plants and chemical plants supply and drainage pipes.
Pipe specification: Φ89-920mm
