Expansion Joint / Stainless Steel Bellows

Widely used in industrial piping systems to absorb thermal expansion and contraction along the straight centerline of the pipeline.

Ideal for power plants, district heating networks, chemical processing plants, oil and gas distribution lines, and HVAC systems.

Suitable for conveying high-temperature utilities such as steam, hot water, exhaust gases, and various chemical fluids.

Bellows Material: Stainless Steel SUS316 (Provides exceptional flexibility, high mechanical strength, and superior resistance to pitting and corrosion).

Size Range: Broad coverage from 25 mm to 1500 mm (1″ to 60″) to fit small process lines up to large-diameter industrial ducting.

Axial Movement Capability: Available in rated movement configurations of 25 mm, 50 mm, and 75 mm (designed to meet varying thermal expansion requirements).

Working Pressure: Handles a versatile pressure range from 1 bar up to 25 bar.

Maximum Working Temperature: Rated for high-temperature operations up to 500°C.

Optimized Thermal Stress Relief: Highly engineered SUS316 corrugations safely compress and extend to neutralize intense thermal expansion, preventing pipe buckling and protecting connected equipment.

High Pressure & Temperature Resilience: Robust construction allows safe, long-term operation under demanding combinations of high internal pressures and extreme temperatures.

Extensive Size Adaptability: The massive scale of available sizes ensures a precise match for both standard utility lines and heavy-duty industrial process piping.
