STWB series expansion joint
STWB20X100S stainless steel
STWB20X100S
STWB20X100S bellows seal expansion joint from the STWB series, designed for industrial piping systems. Stainless steel construction ensures durability, thermal expansion compensation, and vibration resistance. Ideal for high-pressure or temperature applications requiring reliable sealing performance.

Product Description

The STWB20X100S bellows seal is a high-performance stainless steel expansion joint from the STWB series, designed to accommodate thermal expansion, vibration, and misalignment in industrial piping systems. Engineered for demanding environments, it operates within a temperature range of -50°C to +400°C and handles pressures up to 20 bar. The STWB20X100S features a durable 316L stainless steel construction with a nominal diameter of 100mm, ensuring corrosion resistance and long-term reliability in chemical, petrochemical, and power generation applications. Its multi-layered bellows design provides exceptional flexibility while maintaining leak-proof performance. Key advantages include superior fatigue resistance, axial/lateral movement compensation, and compliance with ASME B31.3 standards. Installation requires precise alignment due to its sensitivity to torsional stress, a consideration for system designers. This joint supports direct integration with flanged piping systems using ANSI/ASME B16.5 specifications.
