Model:PE80
A. product
PE gas pipeline safety special polyethylene production using gas, specifications, size and performance in line with GB 15558.1-2003, GB 15558.2-2005 standard. Pipeline with good flexibility, corrosion resistance, light weight, excellent impact resistance characteristics, piping, etc. using Butt and fused connection, pipe, tube melt into one, the system safe, reliable, low cost of construction, in practice, the rapid development. Strong safety vertebral PE gas pipes wide, in line with the Ministry of Construction, the State Economic and Trade Commission guidelines for the development of chemical building materials, improved living standards in line with development needs.
B. The main features of PE gas pipe:
1 excellent physical properties, good flexibility, anti-distortion
2 using hot melt connection, the connection strength and reliability
3 better impact resistance, wear resistance, corrosion
4 long life, up to 50 years, low maintenance costs
C.PE gas pipe Size:
PE gas pipe by GB/15558.1-2003 production, sub-PE80, PE100 two categories, the production size from Φ20-Φ630mm, sub-SDR11, SDR17.6 two series. Color black and yellow striped tube or yellow stripes.
