Flexible rubber joint is assembled with rubber hose and retaining ring flanges, and the rubber hose could be easiely damaged in delivery. So Liangda packs each flexible rubber joint with a separate carton case to prevent the crash of the flanges and rubber hoses, each case painted the name of rubber joint and other details. The carton cases then be filled to plywood cases to ship. Inside of each plywood case, Liangda always uses moistureproof material to keep the products in good condition when delivery.

The Liangda Flexible Rubber 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.
The Flexible Rubber Joint is a single sphere design with less length, the supply range is from 25mm to 3000mm, and design pressure can be 1.0MPa/1.6MPa/2.5MPa, which is always used where low cost or space limitation control.

Flexible Rubber Joint Features and Benefits:
1, Versatile hand-built construction. Made in China 2, Absorbs directional movement 3, Absorbs vibration, noise and shock 4, Compensates for misalignment 5, Wide flowing arch design 6, Virtually eliminates sediment buildup 7, Economical fully molded construction 8, High vacuum rating (up to 30" Hg) can be supplied for certain sizes 9, Special grooved flange ring design, prevent rubber end pull out 10, Solid galvanized steel floating flanges speed the installation time 11, 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 12, No gaskets required; integrally rubber flanged design, no gaskets required, DIN PN10/16 drilling standard, other flange drilling available, including ANSI 150lb/300 lb, BS, and JIS
Flexible Rubber Joint Composition and Material:

1. Flexible Rubber joints supply range can be up to DN3000, detailed data can be offered upon request. 2. Control units must be used when piping is not properly anchored. 3. The rated pressure 2.5MPa products will only be sold with control units. 4. Flexible Rubber joints pressure rating is based on 30°C operating temperature. The pressure rating is reduced at higher temperatures. 5. Flexible Rubber joints weights in the above table are joints with DIN PN16 drilling retaining ring flanges. 6. Movements shown in the above table are non-concurrent. 7. Rated pressure in the above table is the maximum "working pressure". Test pressure is 1.5 times "working pressure", Burst pressure is 4 times " work pressure". 8. Normally, the flange drilling is based on DIN PN16, ANSI 150/250/300 lbs, BS PN10, JIS 10K are also available upon request.
Gongyi City Liangda Tubes Co., Ltd. was established in 1985. Our predecessor is Gongyi Changfen Village Mechanical Factory. In 2007, our company was transformed into a limited liability company (Gongyi City Liangda Tubes Co., Ltd.; GYLDT for short). Since foundation, our company is specialized in the production of rubber expansion joints (flexible rubber joints) , rubber check valves (duckbill valves), steel expansion joints, flexible butterfly valves and flanges.
