Metallic Expansion Joints & Bellows Manufacturer | Flexatherm 

High-Performance Metallic Expansion Joints

Precision-Engineered Solutions for Complex Piping Systems

Flexatherm specializes in the design and production of premium Metallic Expansion Joints (Bellows), which are made to resist corrosive conditions, high pressures, and extremely high temperatures.4 By absorbing thermal expansion, mechanical vibrations, and piping misalignments, our joints are essential for safeguarding your infrastructure. 

Key Features

• Custom Design: Engineered as per EJMA (Expansion Joint Manufacturers Association) standards and ASME codes.

• Extreme Resilience: Capable of handling temperatures from cryogenic levels up to $980^\circ\text{C}$ and pressures from full vacuum to 100 bar+.

• Premium Materials: Manufactured using Stainless Steel (304, 316L, 321) and high-nickel alloys like Inconel, Monel, and Hastelloy.

• Durability: Multi-ply bellows construction for maximum flexibility and extended fatigue life.
