结果仍然是一个长方形的袋子,但在一,背面角度移动的接缝。
The result is still a rectangular bag, but with the seams shifted at an Angle on the back.
可靠的连接性能:PE管热熔或电熔接口的强度高于管材本体,接缝不会由于土壤移动或活载荷的作用断开。
Reliable connectivity: PE pipe hot melt or fused interface strength is higher than the pipe body, joints will not load due to soil movement or the role of living off.
