Product Description
The most reliable rubber joint manufacturer
1 More than 24 years experience manufacturer of rubber expansion joint.
2 The Main Drafter of Chinese Standard (GB/T 26121-2010) flexible rubber joint.
3 Approved supplier for nuclear power industry.
4 The largest rubber expansion joint manufacturer in China(DN3600).
Introduction of double spheres rubber expansion joints:
1. Rubber expansion joints can greatly reduce pipeline system shock and noise. And can fundamentally resolve pipe
joints displacement, axial stretch and non-concentricity.
2. By using different materials, rubber expansion joints can be made many kinds to cater for different medium and environment.
Such as acid resistance, alkali resistance, corrosion resistance, oil resistance and heat resistance etc.
3. The material is pure rubber, sealing is very good. It is in light weight, very easy for installation .
Our rubber expansion joints have long life performance, but must be not contact with sharp metal instruments to avoid piercing the sphere.
4. Our rubber expansion joints can be used for lift and transportation of raw water and sewage, transportation of water supply cooling cycle water thermal power ,condensate water of metallurgy industry and chemical industry.
Benefits of screwed rubber expansion joint:
Flowing arch design prevents sediment buildup and reduces turbulence. Floating flanges can be rotated to accommodate torsion misalignment. Molded spherical bellows accommodate up to one inch of axial movement and transverse deflection polyester-reinforced nitrile tube earns high pressure rating without sacrificing flexibility; Resists most hydrocarbons, oils and gasoline
Features of double spheres rubber expansion joint:
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
Application of screwed rubber expansion joint:
Due to the sound complex performance of the rubber compensators, it is mainly used for the lift and transport of raw water and sewage, and pipeline transportation of feed-water and water for cooling circulation in thermal power plants, condensed water in metallurgy and chemical substances in chemical industry as well as dilution and flexible connection between short and long pipelines. Relying on the high abrasion resistance of rubber, it is also suitable for the transportation under low temperature of powdery and grainy air in any industry.
Packaging & Delivery
Wooden case(Out package) and plastic film and textile membrane(inside package).
We can make change according to your request.
