PVC flat flange
Purpose: connect pipes and valves/equipment, glue the socket + bolt fixation.
Precautions:
Socket treatment:
- Deburr the pipe end and the inner side of the flange socket, and apply special glue (quickly insert and rotate 90°).
Flange alignment:
- The bolt holes of the two flanges must be completely aligned, and the gaskets must be placed in the center (rubber gaskets are recommended).
Bolt tightening sequence:
- Tighten the bolts step by step in diagonal order (2-3 times of force) to ensure uniform pressure.
Avoid stress:
- The pipe must be supported to prevent the flange from being subjected to additional bending force.
