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, petrolio-gas likidotua (GPL) and other gas media. Metalezko hodi tradizionalekin alderatuta, PE gas pipe has become the preferred material in the field of global gas transportation due to its characteristics of light weight, korrosioarekiko erresistentzia, strong impact resistance and long life.

-ren xehetasunak HDPE gas hodia
Korrosioarekiko erresistentzia: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.
Long life service:the design life can reach more than 50 urteak, far more than the metal pipeline (normalean 20-30 urteak).
Eraikuntza erosoa: pisu arina (bakarrik 1/8 altzairuzko hodiarena), 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: ez-toxikoak eta zaporerik gabekoak, in line with drinking water contact standards, eta 100% birziklagarriak.
