Here&#;s the perfect way to absorb pipe motion in small diameter systems. Series H2 High pressure types permit 2&#; pipe motion &#; 1 3/4&#; compression and 1/4&#; extension. Series H3 High pressure types permit 3&#; pipe motion 2 3/4&#; compression and 1/4&#; extension. Senior Flexonics Canada expansion compensators provide the lowest cost method to take up thermal growth.
Senior Flexonics Canada compensators are externally pressurized as opposed to the standard internally pressurized models. The external pressurization principle eliminates the possibility of the bellows buckling, which is one of the major causes of compensator failure.

Expansion Compensators and Housed Expansion Joints are basically a bellows that is protected by and guided within a pipe housing. While the industry offers two styles, one of which is referred to as &#;internally&#; and the other &#;externally pressurized&#;, they both serve the same function but we prefer the &#;externally pressurized&#; for improved bellows stability. They are furnished with a Fixed ASA150 Drilling Raised Face Carbon Steel Flange on the one end and a Floating Flange on the other. The alternates are Carbon Steel Threaded Nipples, Weld or Grooved Ends or Copper Female Sweat Ends as needed.
There are three movement choices: 2&#; (50mm) compression and 1/2&#; (13mm) extension, 4&#; (100mm) compression and 3/4&#; (19mm) extension or 8&#; (200mm) compression and 11/2&#; (38mm) extension. They are all designed for systems that will run hot and the slight extension is only there for those occasions when ambient temperatures are fairly high during installation, and the installation drops to some very low temperatures before they are put into hot water or steam service.
