DN300 304 / 316L stainless steel Metal bellows
1"-30"
Metal bellows are thin-walled flexible metal tubes with continuous circumferential corrugations, normally made of 304 / 316L stainless steel or carbon steel. The corrugated structure allows axial, lateral and angular displacement to absorb thermal expansion, vibration and pipeline misalignment, while maintaining pressure resistance and tight sealing. Widely used in piping systems for chemical, power, heating and petroleum industries as the key component of expansion joints and metal hoses.

1. Product Overview
Metal bellows are flexible, pressure-resistant metallic pipe components with continuous circular corrugations. They are professionally manufactured from high-quality stainless steel and carbon steel via hydraulic forming, rolling and precision welding processes. Different from ordinary rigid pipes and rubber hoses, metal bellows combine metal structural strength with flexible deformation performance. They can effectively buffer mechanical stress, compensate pipeline displacement and ensure stable and safe operation of fluid conveying systems under complex industrial working conditions.
2. Core Features & Advantages
The corrugated structure enables multi-directional displacement including axial stretching/compression, lateral offset and angular deflection. The product perfectly absorbs thermal expansion and contraction caused by temperature difference, eliminates vibration and pipeline noise, and compensates installation deviation and foundation settlement. It greatly protects pipelines, pumps, valves and related equipment from fatigue damage and leakage.
Adopting integral forming and multi-layer reinforcement technology, metal bellows deliver excellent high and low temperature resistance, corrosion resistance and high pressure resistance. They feature reliable sealing, stable elastic recovery, long service life and no aging failure. With compact structure and easy installation, they are suitable for long-term continuous operation in harsh environments.
