Ductile Iron Pipe Fittings High Pressure Couplings

Flexible coupling is also called clamp, open expansion joint, steel flexible pipe joint. It is a kind of pipe connection, reliable performance, easy to install products. At low pressure, by the elastic deformation of the sealing ring, to achieve the purpose of sealing; When the pressure increases, the medium acts on the sealing ring to play the role of self-sealing, and there is a gap between the pipe ends to compensate for the displacement and deflection of the pipe caused by thermal expansion and cold contraction.

This kind of coupling is specially desinged for the pipe bearing high pressure and mainly used in the application like mineral, electric plant, chemistry, etc. It joins roll or cut grooved pipe, grooved fittings, valves, and accessories. It provides a flexible pipe joint designed to accommodate a limited amount of linear and/or angular movement. The high pressure flexible coupling rated pressure is 8.0 MPa.

The rated diameter is 50-200mm.

Outside diameter is 60.3-219.1mm.

Rated pressure is 8.0 MPa.

Bolts and nuts measurement: 2-M10*55, 2-M12*60, 2-M16*75, 2-M16*85, 2-M20*110
