Dismantling Joint Product Information

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. Contact us today. Get the better prices. 30 years of experience.
