Pipe repair clamp is a kind of pipe plugger for repairing pipes, also known as Hafjoint, the upper and lower parts are sealed with sealing strips and fastened as a whole by bolts and worms. 

Manufactured from grade 316 stainless steel for superior corrosion protection
The direct transmission of pressures onto the gasket generates the seal’s tightness, making use of the internal pressure. The gasket is not fixed onto the casing, therefore the clamp allows independent pipe movements.
Clamps available in different lengths and diameters
Suitable for under pressure and pressureless repairs
No sharp corners or edges
No loose parts that can get lost during assembly
Extremely lightweight, therefore easy to handle
