Expansion joints

Expansion joints

ProHydraulics supplies expansion joints for industrial piping systems — from standard solutions to custom configurations for specific operating conditions. Expansion joints absorb axial, lateral and angular movements, dampen vibration and reduce mechanical stress in the pipeline.

Types of movement absorbed: axial · lateral · angular

Industries: metallurgy & steel · oil & gas · power generation · chemical & petrochemical · shipbuilding · HVAC & water supply

Types of Expansion Joints

Rubber expansion joints

Working pressure: up to 25 bar Temperature: up to +200°C Used in water supply systems, HVAC, pump installations and chemical industry. Effectively absorb vibration and noise from pumps and compressors. Available in NBR, EPDM, Neoprene, Butyl, and FKM (Viton) — a material with high chemical resistance and working temperature up to +200°C.

Steel bellows expansion joints

Working pressure: up to 100 bar Temperature: above +500°C Ideal for steam, hot gases, petrochemical media, metallurgy and power generation. Maximum pressure and temperature resistance. Available in carbon steel, stainless steel (304/316L) and special alloys.

PTFE expansion joints

Working pressure: up to 16 bar Temperature: up to +200°C Designed for aggressive chemical media, pharmaceutical and food industries. Exceptional chemical resistance to virtually all media.

Fabric expansion joints

Working pressure: up to 0.5 bar Temperature: above +1000°C Used in flue gas ducts, boiler and turbine gas paths, power generation plants. Highest temperature resistance of all expansion joint types. Made from specially engineered high-temperature materials.

Elastomeric expansion joints

Working pressure: up to 16 bar Temperature: up to +120°C High flexibility, compensating significant angular and lateral movements. Used in water supply, sewage and industrial piping systems.

Comparative characteristics

  • Rubber — pressure up to 25 bar, temperature up to +200°C, chemical resistance: medium — high (FKM/Viton)
  • Steel bellows — pressure up to 100 bar, temperature above +500°C, chemical resistance: high
  • PTFE — pressure up to 16 bar, temperature up to +200°C, chemical resistance: maximum
  • Fabric — pressure up to 0.5 bar, temperature above +1000°C, chemical resistance: depends on material
  • Elastomeric — pressure up to 16 bar, temperature up to +120°C, chemical resistance: medium
