The application field is same for both plugs. They are used mainly for temporarily blocking the pipe line. But the CP model plugs do have some advantages when compared to PP model plugs.
- For its size, a CP plug has a relatively lower weight
- A CP plug can be tightly folded for easy insertion through narrow openings
- CP plugs do not usually require additional bracing
- CP plugs are repairable
- A CP plug can be used for many different pipe profiles, including egg-shaped profiles, kite profiles, throat profiles, rectangular channels, dry-weather channels and open U-channels. One single device may thus meet many of your project’s needs.
