Stainless Steel Expansion Bellows SS304 SS316 Flexible Compensator 32-400mm Diameter -70°C to 260°C

Stainless steel flexible compensators are engineered to absorb dimensional changes caused by thermal expansion, contraction, and mechanical displacement in pipeline systems. These SS304 and SS316 expansion bellows provide reliable compensation for axial, lateral, and angular movements while reducing noise and vibration.

• Wide temperature range: -70°C to 260°C (higher temperatures available on request)
• Excellent weather resistance with 10-year service life
• High insulation performance: dielectric constant 3-3.2, breakdown voltage 20-50KV/MM
• Superior flexibility with high surface friction and elasticity
• Multi-directional compensation for axial, angular, and lateral displacements
• No reverse thrust design simplifies installation and reduces structural requirements
• Excellent sealing performance with silicon and fluorine polymer coatings
• Easy installation and maintenance

Available in nominal diameters from 32mm to 400mm with pressure ratings from 0.25MPa to 2.5MPa. Multiple wave configurations provide optimal compensation capacity for various industrial applications.

Widely used in thermal pipelines, chemical processing systems, oil pipelines, water supply and drainage systems where temperature fluctuations and mechanical stresses require reliable compensation solutions.

Proper installation following manufacturer specifications ensures optimal performance. Regular inspection for bellows damage, connector integrity, and proper alignment maintains system reliability and prevents pipeline deformation issues.
