In high-pressure industrial environments, piping systems are constantly subjected to thermal expansion and mechanical stress. Without a way to compensate for these forces, pipes would buckle or leak. This is where Metal Bellows Expansion Joints become critical components.
Why Material Choice Matters: AISI 304 and P265GH
At VANOX, we believe that the reliability of an expansion joint starts with its materials. Our production standards prioritize durability and performance:
- AISI 304 Stainless Steel: This material is the heart of the bellows, offering the necessary elastic properties to absorb repeated movements without fatigue.
- P265GH Steel Pipes: Known for its excellent heat resistance, P265GH is our preferred choice for pipe connections in demanding thermal systems.
- ST37 Lugs & 8.8 Rods: For hardware that lasts, we use ST37 for lugs and high-tensile 8.8 grade rods to secure the assembly.
Applications and Movement Compensation
Metal bellows are engineered to handle three primary types of movement: Axial (along the pipe’s length), Lateral (offsetting), and Angular (bending). To protect the bellows from extreme temperatures, we integrate ceramic wool insulation, which extends the service life of the entire system
Custom Manufacturing: From DN600 to DN2600
Every project has unique demands.Whether you need a standard DN800 joint or a massive DN2600 industrial solution, VANOX provides tested and certified products. Our engineering team ensures that every unit meets 1.5x design pressure or leak test standards before shipment.
