Seals Leaks at Socket Joints with Banding Clamp
The Pipe Socket Repair Clamp is a banding-type clamp made for socket joint leaks. Socket joints have a raised bell profile. Standard banding clamps cannot fit over the bell. Our clamp has an enlarged cavity that matches the bell shape. It covers the bell completely and seals on both sides.
The housing has a cavity that fits over the bell profile. The sealing pad has two sealing zones. One zone seals against the pipe body behind the bell. The other zone seals against the pipe body in front of the bell. The clamp slides onto the pipe from the side. You place it over the bell and tighten the bolts. The two sealing zones work together to stop leaks at the socket. This clamp is good for leaks caused by old rubber rings or cracked pipe ends at the socket.
We have many patents for socket repair products. Our technical team can custom-match the clamp to your socket dimensions. We hold ISO 9001 certification. Our products are reliable and field-proven. Our annual sales exceed 80 million RMB.
Used on Coastal Water Line
A coastal tourist city had a water line under the main road. The socket joints were corroding from salt water. The road could not be closed for long. The repair team used our Pipe Socket Repair Clamp during a low-traffic night period. They completed the work in four hours including backfilling. Traffic was back to normal by morning. The epoxy coating passed salt spray tests for coastal environments. The gasket is seawater-resistant EPDM.
We offer a 10-year warranty. We custom-make each clamp based on your socket dimensions.
