وصلات تمدد بيلوز (Bellows Expansion Joints)
Bellows expansion joints are flexible connectors consisting of one or more corrugated bellows elements designed to absorb thermal expansion, contraction, and mechanical vibration in piping systems. Available in axial (single and universal), lateral, angular (hinged and gimbal), and pressure-balanced configurations, each type is engineered for specific movement patterns and system constraints.
Our bellows are hydroformed or mechanically formed from stainless steel sheet (SS304, SS316L, SS321, Inconel 625) with optimized convolution geometry for fatigue life. Multi-ply designs offer increased flexibility and cycle life while maintaining full pressure capability. Each joint can be supplied with tie rods, limit rods, hinges, gimbal rings, internal flow liners, and external protective shrouds as required by the application.
