Customers need lined pipe trench, in use, should have the following advantages: 1. processing performance stability: PEX with controlling the degree of crosslinking and crosslinking uniformity and other problems, and the processing of complex machining directly affect the pipe performance. 2. Long-term pressure resistance, only in terms of design stress, pressure resistance GB lined pipe trench best. However, due to various factors, the actual thickness of the floor heating pipe is usually 2mm. And in this types of pipe wall thickness can meet the requirements of floor heating, reducing elbow pipe pressure not manifest advantages. 3. The thermal conductivity: for floor heating pipes need to have good thermal conductivity. The low temperature thermal shock resistance: PE - RT and low temperature impact properties PEX better. Winter construction of pipe rupture less susceptible to shocks, increasing the flexibility of the construction schedule. 5. Environmental protection: PE-RT can be recycled, do not pollute the environment. PEX can not be recycled and will produce secondary pollution. Custom lined pipe trench, please contact www.wfyhgy.com
