Single Ball Flange Rubber Expansion Joint NBR EPDM Stainless Steel Flange

Single Ball Flange Rubber Bellows Expansion Joint Custom NBR EPDM Rubber Stainless Steel Flange

Flexible rubber expansion joints are composed of rubber spheres and metal flanges, with the flange ends connected to pipe flanges.

Materials for pump and valve-specific expansion joints feature:

• Corrosion resistance, wear resistance, acid and alkali resistance
• Non-hygroscopic properties with good elasticity
• Resistance to thermal expansion and pipe diameter reduction
• Reduction of thermal expansion or stress from temperature changes

These components are essential in pipeline systems, offering compact size, lightweight design, easy installation, and material savings. They help reduce vibration and noise in systems with significant vibration (such as pump systems).

Available sizes range from DN15 to DN4000. Custom specifications available upon request.

The flexible rubber single ball rubber joint has excellent comprehensive properties and is widely used in:

• Chemical industry
• Construction and water supply
• Drainage and oil industries
• Light and heavy industry
• Refrigeration and sanitation
• Plumbing, fire protection, and electrical infrastructure

Available in various materials to accommodate different environments:

• Acid, alkali, and corrosion resistant
• Oil resistant and high temperature resistant
• Radiation resistant and wear-resistant
• Anti-aging varieties available
