Hyspan - Model Series 8500 - Expansion Compensators
Series 8500 Expansion Compensators are designed for installations where the principal movement is axial. Standard designs are 3/4” through 4” for steel pipe and copper tube with 2” or 3”axial compression. Service conditions are 200 psig to 500°F. Steel pipe ends are threaded, welded, grooved or flanged. Copper tube ends are male or female sweat connections.
The bellows element of Series 8500 Expansion Compensators is completely enclosed and externally pressurized which prevents damage to the bellows and eliminates pressure instability. The pipe or tube telescopes into the compensator providing a smooth full bore, and isolates the bellows from the flow. Series 8500 products are available from stock and have a Three year full replacement warranty.
