Pex-al-pex pipes are designed with special polythene both inside and outside, being clean and smooth. The aluminum layer in the middle is of 100% insulation Features: 1) Specification: Φ16 - 32 2) Non-toxic, anti-corrosive 3) Light weight, strong mechanical properties and thermal-resistant ability 4) Low fragile humidity and long using life 5) Low flowing resistance inside the pipe, scaling can rarely happen 6) The fluids cannot be contaminated. Effective diameters are big 7) Oxygen is 100% isolated and infiltration is thoroughly prevented. In case they are used as shielding materials for telecommunication circuit, magnetic interference can be prevented 8) Anti-static, and suitable for gas and fuel transportation 9) Can be bended or straightened withoutrestriction
