Polyethylene Gas Pipe (PE gas pipe, short for PE gas pipe) is a pipeline system made of high density polyethylene (HDPE) as raw materials through extrusion molding process, specially designed for the transportation of natural gas, sıvılaştırılmış petrol gazı (LPG) and other gas media. Geleneksel metal borularla karşılaştırıldığında, PE gas pipe has become the preferred material in the field of global gas transportation due to its characteristics of light weight, korozyon direnci, strong impact resistance and long life.
Polyethylene Gas Pipe (PE gas pipe, short for PE gas pipe) is a pipeline system made of high density polyethylene (HDPE) or medium density polyethylene (MDPE) as raw materials through extrusion molding process, specially designed for the transportation of natural gas, sıvılaştırılmış petrol gazı (LPG) and other gas media. Geleneksel metal borularla karşılaştırıldığında, PE gas pipe has become the preferred material in the field of global gas transportation due to its characteristics of light weight, korozyon direnci, strong impact resistance and long life.
Ayrıntıları HDPE Gas Pipe
Korozyon direnci:PE material has natural resistance to chemical corrosion, electrochemical corrosion and soil microbial erosion, without additional anti-corrosion treatment.
Flexibility and shock resistance:The pipeline has high flexibility, which can adapt to external deformation such as terrain settlement or earthquake, and reduce the risk of leakage.
Uzun ömürlü hizmet:the design life can reach more than 50 yıllar, far more than the metal pipeline (genellikle 20-30 yıllar).
Convenient construction: hafif (sadece 1/8 of the steel pipe), support trenchless construction (such as directional drilling), greatly reduce installation costs.
Good sealing: using hot melt connection technology, the interface strength is consistent with the pipe body, and the potential gas leakage is eliminated.
Environmental safety: toksik olmayan ve tatsız, in line with drinking water contact standards, Ve 100% geri dönüştürülebilir.
