HUATAO GROUP
Type II heat-resistant polyethylene pipeline raw materials
Product Description
Type II heat-resistant polyethylene pipeline raw materials are also known as the fourth-generation polyethylene pipeline raw materials. It not only retains the excellent low-temperature impact resistance, hygienic performance, flexibility and other characteristics of PE-RT type I materials, but also has better long-term hydrostatic strength, environmental stress cracking resistance and long-term aging resistance.This determines that it is suitable for the design, construction and acceptance of PE-RTⅡ type heating pipeline projects with a working pressure of not more than 1.0MPa, a design temperature of not more than 85℃, and a nominal outer diameter of less than or equal to 450mm.(Mainly used in hot spring pipelines, central heating secondary pipe networks, drinking water, domestic hot water, air-conditioning circulating water, garden pipe networks and other systems)
