Gongyi Lianda Tubes Co.,Ltd

Our dismantling joint is designed to be the final closing piece in the pipe network, to ease the assembling and disassembling for later maintenance of a pump or valve. A standard adjusting range of 50mm on length and a small lateral and angular misalignment can be accommodated. This adjustability of the dismantling joint facilitates for easy removal of pumps and valves in circumstances of inspection, maintenance or replacement. Features and Benefit: •Compensate for differences in flange to flange distance •Simplify the installation of pipelines •Integrate a valve or pump into a flanged pipe network •Flange connection, flange drilling can base on DIN PN6/16/25, ANSI CLASS150/300, JIS, EN, etc •Reduce assembling time •Dismantle for service, inspection and maintenance •Epoxy powder coating and bolting made of steel •Drinking water approved Specifications Nominal diameter: DN80mm to DN3000mm Maximum working pressure: 4.0 Mpa Vacuum KPa(mmHg) 44.9(350) Operating temperature: -20℃-80℃ Corrosion resistance Good Applicable media Sea water, drinking water, slurry, industrial sewage.

We offer Threaded Union Flexible Rubber Joint. The Liangda Rubber Flexible Connector are designed for piping systems to absorb pipe movements, relieve stress, reduce system noise/vibration, compensate for misalignment/offset and to protect rotating mechanical equipment against start-up surge forces. Because of rubber has superior capability in resistance of acid, alkali, oil, and electrolytic, Thread Union Rubber Coupling has become one of the alternatives of stainless steel and been successfully installed in tough demanding applications such as: Chemical/Petrochemical, Marine, Power Generation, Pulp/Paper, Steel Mills and Water/Wastewater Treatment. The Liangda Rubber expansion joints is a twin sphere design with BSPT female threads, the supply range is from 12mm to 80mm, and design pressure can be withstand 1.0MPa/1.6MPa/2.5MPa working pressure. Compared to flange connected Rubber Joint, the threaded rubber joints are less weight and easier to install, special designed for threaded piping system. Meanwhile, the twin sphere designs are more flexible and allow greater movement.
