Although the pipe repair straub coupling is easy to install, it must be carefully operated according to the instructions, otherwise it will lead to leakage of the pipe, and even explosion in severe cases. The following will tell you what problems may occur during the installation process.

1. Do not draw a line on the pipe end first during installation.
Line drawing is an important step in the installation of pipe repair straub coupling. It can help us avoid the pipe tilting during the installation process, and at the same time, it can accurately lock the connection part, so that the inner rubber ring can completely cover both ends of the pipe.
2. There is a problem with the outer diameter of the pipe
Often when we choose the pipe repair straub coupling, we refer to the nominal diameter DN for purchase. One specification of DN corresponds to the outer diameter of the two sizes of pipes. Determine which outer diameter of the pipe we need. If the outer diameter of the pipe is correct On the other hand, the pipes and connectors cannot be closely connected, which will cause problems such as disconnection and leakage.
3. Install without the torque on the installation instructions
The manufacturer of pipe repair straub coupling tells you that we must refer to the torque on the manual for installation when twisting the bolts. If the torque is not reached, the pipe connection will not be tight enough. If the torque is too large, the bolts will be tripped. Both methods will cause There is a problem with the plumbing connection.
