Description

Galvanized Rubber Expansion Joint

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.

The flexible rubber bellow 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.

Galvanized rubber expansion bellows
 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

NOTE:

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.
