Description

The Liangda Rubber Expansion Joint is 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, Rubber Expansion Joint 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 Eccentric flexible rubber bellow is a twin sphere design with more length, the supply range is from *0mm×*5mm to **0mm×**0mm, and design pressure can withstand 1.0MPa/1.6MPa/2.5MPa working pressure. The rubber expansion bellows are engineered special for pipe reducing and offsetting pipe misalignment. It offers an economic and space saving way to combine a reducing pipe fitting with an expansion joint, different sized pipe can be jointed by big and small flanges. Specifying Liangda expansion joint rubber to help solve piping system vibration or movements problems as well as connection problems.
Features and Benefits:
1, Versatile hand-built construction. Made in China2, Absorbs directional movement3, Absorbs vibration, noise and shock4, Compensates for misalignment5, More compensation capability6, Combine a reducing pipe with an expansion joint7, Embedded steel reinforce ring enable the pressure resistance8, Solid galvanized steel floating flanges speed the installation time9, Special grooved flange ring design, prevent rubber end pull out*0, High tensile aircraft cable is embedded in the raised face rubber ends to prevent pull out and avoids the sharp cutting edge of solid steel rings*1, No gaskets required; integrally rubber flanged design, no gaskets required, DIN PN*0/*6 drilling standard, other flange drilling available, including ANSI **0lb/**0 lb, BS, and JIS
