PTFE Lining Stainless Steel Metal Bellows Expansion Joint Compensator

DN25 1''-DN3000 125''
The PTFE-Lined Stainless Steel Metal Bellows Expansion Joint Compensator is a high-performance piping component designed to absorb thermal expansion, vibration, and misalignment in pipeline systems while providing superior resistance to corrosive media. Combining the mechanical strength of stainless steel bellows with the chemical inertness of PTFE lining, this product is widely used in chemical, petrochemical, pharmaceutical, and food processing industries.

Key Features
Excellent Corrosion Resistance – The PTFE lining protects the stainless steel bellows from aggressive acids, alkalis, solvents, and other corrosive fluids.
High Flexibility & Compensation – The metal bellows design effectively absorbs axial, lateral, and angular movements caused by thermal expansion or mechanical vibration.
Durable Stainless Steel Construction – Made from high-quality stainless steel (304, 316, 316L, etc.) for strength, pressure resistance, and long service life.
Smooth & Non-Stick Surface – PTFE lining provides a low-friction, non-stick surface that prevents media accumulation and reduces flow resistance.
Wide Temperature Range – Suitable for applications from -20°C to 200°C (depending on PTFE grade and design).
Customizable Designs – Available in various flange standards (ANSI, DIN, JIS, GB), sizes, and pressure ratings.
