Specifications

product name: pert-al-pert composite pipe
specification:16/20/25/32mm
1.25Mpa working pressure,95 temperature
GB/T18997.2

Description:

1. have the strength equal to metal pipe, and tends to be bended without bounce 2.Resistance to high temperature, high pressure, corrosion with excellent performance. 3.Inner wall of the pipe is smooth, thus resistance to fluid transportation is small, Capacity of fluid transportation is superior to metal pipe of the same diameter by 30% 4. Property of fire retardation 5.Good performance of heat insulation with a thermal conductivity of 0.45w/m.k, whihc is samller thatn that of metal pipe by far, Thus heat insulation meterial outside the pipe may be saved. 6. Be convenience for cutting and construction.Special-purpose fittings connection may be used instedn of threading. Pipe of small diameter is supplied in roll. the length of pipe may be determined at will. and pipe may be bended at will thus bend and pipe fittings are unnecessary. which is convenience for construction. therefore, labor cost can be reduced and time limit for the profect would be shortened
