Customizable stainless steel flange connection double sphere rubber expansion joint

The installation length of the double ball rubber joint is longer than that of the single ball rubber joint.

Applicable to: some water pump equipment with high vibration frequency and high noise. The increase in product length effectively ensures good sound insulation effect!

Temperature

-15 ~ 80℃

Flange Standard

DIN, ANSI, JIS etc

Material of Flange

Stainless Steel 304, 316, 321 etc

Material of Rubber

EPDM, natural rubber, NBR rubber and neoprene rubber

Performance characteristics:

Flexible rubber joints are also called shock absorbers, pipeline shock absorbers, shock absorber throats, soft joints, etc. They are a kind of pipeline joints with high elasticity, high air tightness, medium resistance and weather resistance. Its performance characteristics are:

1. Small size, light weight, good elasticity, easy installation and maintenance.

2. It can produce lateral, axial and angular displacement during installation, and is not restricted by the user's pipeline non-concentricity and flange non-parallelism.

3. It can reduce structural transmission noise during operation and has strong vibration absorption ability.

4. Our independently developed internal seamless high-pressure flexible rubber joints can more effectively prevent corrosive media from corroding the inner wall of the flexible rubber joint in high temperature resistant, acid and alkali resistant and oil resistant pipelines, and improve the service life.

Note: 1. Special requirements can be made according to user drawings. The sphere can be made of nitrile rubber, EPDM, chloroprene rubber and other materials. 2. For suspended water supply, use products above DN200. The pipeline must have a fixed support or fixed bracket, otherwise the product should be installed with an anti-pull-off device. 3. If the user uses a rubber joint, the corresponding flange should be a valve flange.
