摘要
介绍了PE管热熔连接和电熔连接的原理及特点,对热熔焊缝对气体流动的影响进行了实验和数值模拟研究,得出单个热熔焊缝阻力系数。
The principle and characteristics of PE pipe hot melt connection and electrofusion con- nection are introduced. The influence of hot melt welding joint on gas flow is studied by experiment numerical simulation, and the resistance coefficient of the hot melt welding joint is achieved.
