Do You Know How to Connect Grooved Pipe Fittings?

Connecting grooved pipe fittings is a simple, tool-assisted process that replaces welding and flanging. The basic principle is to machine a groove at each steel pipe end, place a sealing rubber ring between the two pipe ends, and fasten a clamp around the grooves to form a sealed, flexible joint.

The grooved connection offers fast on-site assembly, easy disassembly for maintenance, and good resistance to vibration and slight pipe misalignment. It is widely used in fire protection, water supply, HVAC and industrial piping where schedule and reliability matter.

For best results, always verify groove dimensions against the fitting specification, use intact rings with neutral lubricant, tighten bolts symmetrically to the specified torque, and perform a pressure test after completion.
