2-Convolution Welded Bellows Assembly

2-Wave Welded Bellows Assembly,Capable of compensating for displacement within specified ranges axially, laterally, or angularly, absorbing deformation caused by thermal expansion/contraction and vibration in pipelines and equipment.

Description

Ultra High Pressure Resistance

Robust 2-wave structure delivers excellent stiffness, stable under high pressure and prevents buckling.
Compact & Short Overall Length

Minimal installation space, perfect for tight flange-to-flange and confined piping layouts.
High Structural Rigidity & Stability

Low deflection, strong resistance to pressure thrust, keeps system aligned safely.
Precise Small Displacement Compensation

Absorbs limited axial movement, minor misalignment and light thermal expansion.
Long Fatigue Life Under Heavy Loads

Optimized welded construction reduces stress concentration, suitable for pressure pulsation conditions.
Zero Leakage & Full Vacuum Tightness

All welded metal design, no rubber, aging-free, airtight for steam, gas, oil and vacuum lines.
Low Spring Force & Reliable Performance

Controlled reaction force protects valves, pumps and sensitive equipment.
High Temperature & Corrosion Resistant

Available in stainless steel 304 / 316L / Inconel for harsh chemical & thermal environments.
Easy Installation & Maintenance-Free

Integrated welded assembly, quick fitting, no replacement needed over long service periods.
