High Pressure Single Ball Rubber Expansion Joints DN32-DN3000mm 1.0-4.0MPa with Tie Rod for Pipeline Systems
The flanged rubber expansion joint is a high-performance flexible connector designed for metal pipeline systems. Engineered with an inner rubber layer, reinforced rubber ball with nylon cord fabric, composite outer rubber layer, and loose metal flange, this joint delivers exceptional pressure resistance, superior elasticity, and significant displacement compensation capabilities.
- Superior Elasticity: Accommodates lateral, axial, and angular displacement during installation, unaffected by pipeline non-concentricity or non-parallel flanges
- Excellent Sealing Performance: End face fully seals with flange surface, providing reliable waterproof sealing without additional gaskets
- Comprehensive Displacement Compensation: Effectively compensates for pipeline movement due to temperature changes and vibration
- High Pressure & Tensile Resistance: Withstands pressures up to 4.0MPa, ideal for demanding pipeline systems
- Wide Application Range: Suitable for chemical, construction, water supply, drainage, petroleum, heavy industry, and power engineering
