Project Description

Expansion Compensators

In this paragraph, I am going to explain about expansion compensators. First they are designed for installations where the principal movement is axial. Foremost standard designs are 3/4” through 4” for steel pipe and copper tube with 2” or 3”axial compression. Next Copper tube ends are male or female sweat connections. And the pipe or tube, telescopes into the compensator providing a smooth full bore, and isolates the bellows from the flow. Additionally Contact Us for a quote or more information.

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.

Furthermore, expansion compensators provide a maintenance-free, compact, economical, and reliable method of eliminating this problem. Moreover the compact design of Expansion Compensators permits installation within tight spaces. And the inline construction minimizes pressure drop and heat loss. And the metal bellows is fully enclosed, and internal and external guides maintain alignment. Moreover, all welded or high-temperature brazed construction eliminates the need for maintenance.

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 extension (pipe contraction), the compensator can be preset at the factory. The piping system must include anchors to react the force produced by pressure thrust and the bellows.

Installation Instructions

In this paragraph, I am going to tell you about installation. First off they are available for 2″ and 3″ axial travel. Secondly consult the purchase specification for the allowable travel of the product purchased. 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 for Expansion Compensators. But not exceed 1000°F during installation.
