Externally Pressurized Expansion Joints

Advanced Technology for High Pressure and Large Expansion Rates

In externally pressurized expansion joints, the fluid flows around the outside of the bellows rather than through the inside. This structural difference prevents the bellows from squirming and allows for high expansion values like 30, 60, 90, or even 120 mm to be compensated with a single unit.

Technical Advantages

• • Connection Types: Available in Flanged or Welding Neck types according to project requirements.
• • Enhanced Stability: External pressure ensures stability in high-stroke movements.
• • Stainless Steel Bellows: Corrosion-resistant bellows manufactured from AISI 304, 316, or 321.

Applications

Geothermal energy lines, district heating, refineries, and high-pressure steam distribution networks.
