产品介绍
刚性管接头连接：
刚性管接头连接方式使系统不具柔性，管接头卡紧后可与钢管形成刚性一体， 在吊具跨度较大时，使管道依靠自身刚性支撑连接。
Rigid Couplings can not enable the connection system to be flexible, and the couplings are integrated with steel pipes after they are fastened. If the sling has a bigger span, the pipes will support the connection depending on their own rigidity.
