Stainless Steel Expansion Bellows

The Stainless Steel Expansion Bellows is a precision-engineered flexible component designed to absorb thermal expansion, vibration, and mechanical misalignment in piping and ducting systems. Manufactured with a corrugated cylindrical body and smooth end connections, this component ensures controlled axial flexibility while maintaining structural integrity under pressure and temperature variations.

The design features uniform convolution geometry optimized for flexibility and stress distribution, along with straight end sections prepared for welding integration into pipeline assemblies. The smooth internal bore supports consistent flow characteristics, while the external corrugations provide the required elasticity for dynamic system movement. Clean surface continuity and accurate proportions make this model suitable for engineering visualization, piping layout integration, and technical documentation.

This CAD model is ideal for professional use in mechanical design studies, piping system simulations, and high-quality industrial rendering.
