PERT II pre-insulated pipe is divided into 3 layers.
The inner layer is the PERT II pressure pipe, high temperature& stress resistance.
The middle layer is the PU (polyurethane) foam, excellent insulation function, heat conductivity only 0.032W/mK.
The outer layer is the protection layer, made by HDPE thin wall pipe.
The heat conductivity of PERT II pipe is 1% of steel pipe.
Only 0.1°C loss per kilo meter.
The three layers expansion coefficient is similar, combine together tightly. Smart Joint produce the pre-insulated pipe one time, which guarantees the good insulation quality and save the pipe cost.
Pre-insulated pipe feature:
Max. working temp. 80°C, failure temp. 110°C softening point,
Max. working pressure 1.0 Mpa, considering ratio of designing stress calculation 1.25-1.5,
Ring stiffness(external stress load) SN20 according to thermal plastic pipe ring stiffness test,
Working life span 30-50 years, 50 years under working temp. 70°C. lower temperature, longer life span,
