Product Description
SS304 PTFE Lined Stainless Steel Exhaust Bellows Expansion Joint
A PTFE-lined bellows expansion joint is an essential component in piping systems designed for handling highly corrosive or chemically aggressive media. This specialized joint combines the flexibility of stainless steel bellows with the exceptional chemical resistance of Polytetrafluoroethylene (PTFE), providing reliable performance in demanding industrial environments.
Product Overview
The expansion joint features an outer stainless steel bellows structure with a seamless, formed PTFE liner that protects the primary bellows material from direct contact with corrosive process fluids.
Movement Compensation Capabilities
- Axial movement: Expansion and contraction along pipe length due to temperature changes
- Lateral movement: Side-to-side displacement compensation
- Angular movement: Rotational or bending movement absorption
- Vibration dampening: Mechanical vibration reduction from pumps and equipment
- Misalignment compensation: Adjustment for minor installation inaccuracies
