PN16 ANSI Standard SS304/316 Stainless Steel Flange Rubber Expansion Soft Joint

• High elasticity and air tightness: Withstands high pressure while maintaining excellent sealing for pipeline systems.
• Medium resistance: Compatible with various media including water, sewage, oils, gases, steam, and granular powders.
• Shock reduction and noise absorption: Lightweight design effectively reduces structure-borne noise and vibration transmission.
• Diverse classifications: Available in single sphere, double sphere, three sphere, reducer types, clamp type, 90° rubber elbow, and specialized versions for high temperature, acid/alkali, and wear resistance.
• Wide application range: Ideal for pump/valve connections, high-vibration pipelines, and systems with frequent thermal cycling.
• Easy installation: Requires proper flange welding alignment and fastener connection, followed by pressure testing to ensure leak-free operation.

The rubber soft joint consists of a multi-layer construction with inner rubber layer, reinforcing nylon cord fabric, and outer rubber layer. Material selection varies by application:

Available rubber types: Natural rubber, styrene butadiene, butyl, nitrile, EPDM, neoprene, silicone, and fluorocarbon - each offering specific resistance to heat, chemicals, corrosion, wear, or oils.
