Details Description
Product Introduction
he sealing rubber ring is wound around the ends of the two connected pipes during assembly to form an initial seal.
The two-piece clamp is sleeved on the outside of the sealing ring, and the protruding part of its inner edge will precisely fit into the annular groove at the end of the pipe.
The bolts and nuts are tightened by evenly tightening the bolts to pull the two clamps together. This action will simultaneously compress the sealing ring to enhance the seal and mechanically interlock the raised part of the clamp with the pipe groove, thereby completely preventing the pipe from being pulled apart or rotated.
The grooved rigid coupling is a specialized component for mechanical connection of pipes. It forms a rigid, weld-like stable connection between the ends of pipes that have been pre-machined with annular grooves through clamps, gaskets and bolts. It is widely used in systems such as fire protection and industry where high stability of pipelines is required.
Product Features
• After connection, relative movement is not allowed to form a rigid coupling system.
• Compared with traditional welding or flange connection, its installation is faster and safer (no hot work is required), and it is also convenient for later system maintenance and renovation.
• The "heel" structure on the inner edge of the clamp will be deeply inserted into the pipe groove to achieve mechanical locking.
