Installation method of flange-type interface ductile cast pipe

Due to the excellent performance of ductile pipe fittings, it will be used in many fields now, and it is also very convenient to use. In fact, as long as the correct method is mastered, the installation method of ductile cast pipe is relatively simple. The following ductile iron pipe manufacturer will share with you the installation method of flange interface ductile cast pipe. The detailed information is as follows:

Pipe fittings

The first step is to check the surface quality of the flange and the rubber gasket, clean the sealing surface of the flange, and then arrange the installation sequence, and then leave a little gap between the two flanges to be connected to insert the rubber gasket. ;

The second step is to insert a rubber gasket between the two flanges and put on bolts. The seal can be fixed with the help of tape, so that the rubber gasket is in the sealing face of the convex part of the two flanges.;

The third step is to tighten the bolts in order. It is best to use a force measuring wrench to make the bolts reach the required torque.

In addition, it should be noted that the bolts must be checked after the pressure test of the ductile iron pipe, and it is necessary to tighten it again. 　 In short, you only need to follow the tightening sequence and torque of the bolts during installation and master the correct installation steps. . I hope that the information brought by the ductile iron pipe manufacturers will be helpful to you!
