Project Description

Expansion Compensator

In this paragraph, I will discuss quality with you. First of all, PermaPax expansion joints are high-quality products with standard performance, and the sealing system is made of carbon fiber yarn impregnated with graphite. In particular, these sealing materials remain flexible throughout their service life. This provides you with the additional benefit of lubricating the moving tube.

Design

  • Sizes 3/4” through 4.”
  • Threaded, welded, flanged, and grooved steel pipe joints.
  • Male and female copper sweat ends.
  • Design pressure: 200 PSIG—see Copper Tube.
  • Axial travel: 2” and 3.”
  • Fully enclosed and externally pressurized, multiply stainless steel bellows.
  • Internal guides maintain alignment.

Applications

Expansion Compensators are designed for installations where the principal movement is axial. Also, standard joints are designed for 2” or 3” axial compression (pipe expansion) and 0.5” extension. If the primary movement is an extension (pipe contraction), the expansion compensator can be preset at the factory. The piping system must include anchors to react to the force produced by pressure thrust and the bellows.

Installation Instructions

In this paragraph, I am going to tell you about installation. Firstly, Expansion Compensators are available for 2″ and 3″ axial travel. Secondly, check the specification for the allowable travel of the product. But be certain that the system conditions and test conditions do not exceed these values. Guides, supports, anchors: Expansion Compensators are designed for applications where the principal movement is axial to the centerline of the compensator, and the system includes guides, supports, and anchors. Finally, the flow can be in either direction. But not exceed 1000°F during installation.
