Ductile Iron Water Pipe Fittings Dismantling Joint PN10-PN25

Dismantling joint

1. PRODUCT PROFILE

Dismantling joint is specially designed to provide an easy method of removing or installing any kind of flanged product in a pipeline, such as valves, pumps, flanged pipe fittings or other similar products. Final anchoring is ensured by the supply of tie-rods, which are also used as flange jointing bolts that reduce the number of bolts required. Because of their greater flexibility and economy, dismantling joints are steadily replaced flanged pipe joints in plant and marine applications presently. Unlike flanged joints, couplings not only eliminate the need for costly welding but also compensate for extreme degrees of pipe linear expansion, vibration and laying deflection. From chemical plants to mammoth tankers, these couplings are utilized extensively throughout plant and marine piping as a wide range of models is available. These pipe fittings are widely used in water, sewage and neutral liquids fields up to 70℃ with size from 50mm to 2000mm.

2. FEATURES

· ±25mm longitudinal adjustment simplifies future pipework modifications, reducing down time

· Can be locked at required length with tie rods supplied

· FBE anticorrosive coated make long service life

· Both restrained or un-restrained styles for selection

· The integral tie-bar assembly avoid the need for other external restraints

· Special configurations and high pressure alternatives are available on request

· The dismantling joint is particularly suitable for simplifying the installation and removal of valves, pipes and fittings of non-return valves, check valve, isolation valve, control valve, flow metering equipment, pump sets, pressure reducing valve, flanged pipe and fitting.
