Overview
1 Overview
Underground gas pipe network in the city system, polyethylene (PE) pipes are more and more applications. As with life, with the performance, welding is simple, good sealing performance, easy to use ball valve of polyethylene pipes have been indispensable to the control as more and more use of components and attention.
2, material selection
Polyethylene is a thermoplastic engineering plastic material, has certain strength, stiffness, toughness, impact resistance, corrosion resistance and wears resistance. By controlling the polymerization process and in the polymerization by adding a certain amount of co monomer, you can adjust or improve the performance of polyethylene material. Therefore, advanced polymerization process or a direct result of differences in material properties. For long-term safe operation of pipeline systems, gas pipes, fittings and valves must be graded according to the type of material Pipe Compound (PE80, PE100), and mixed ingredients, can not use the master batch. Material color is generally black and yellow.
