Flanged Fully Stainless Steel Expansion Joint DN200-PN10

This DN 200 fully stainless steel expansion joint is designed to absorb axial movements, such as compression and extension in piping systems. It has 8 bolt holes on each side to connect to pipes. This compensator is ideal for applications involving thermal expansion and vibration damping. The flanges and bellows are made of 1.4404b stainless steel. It is suitable for temperatures of up to 550°C, but pressure resistance drops as temperature increases. This expansion joint is used to compensate movements in pipelines carrying corrosive substances, damping vibrations and compensating for thermal expansion in heating and cooling systems and ensuring the integrity of pipelines in processing and transportation. Reference values for the pressure rating under temperature loading: up to +20°C: 100%, +50°C: 90%, +150°C: 76%, +250°C: 69%, +350°C: 64%, +550°C: 59%.

Pros:

• High temperature resistance of up to +550 °C
• Robust stainless-steel flanges and bellows (1.4404b) ensure durability and corrosion resistance
• Suitable for vacuum, pressures ranging from -1 to 16 bar
• Axial flexibility accommodates 19 mm of both compression and extension

Cons:

• Not suitable for lateral offset and angular deviation
