One of the greatest challenges in designing compensators is finding a solution to the problems occurring in production lines conveying highly viscous substances, including asphalt, tar, chemical products, etc. Because of the nature of these substances as well as bellow construction, the flow of the medium through the compensator is substantially restricted. Such substances may pose a risk of sedimentation and building up in the corrugations of the compensator, hindering the flow and, in the worst case, completely clogging the line. In these cases increasing the temperature of the medium (heating the medium) can result in significant reduction or even totally eradicate such problems.

Chamber expansion joints
  • Increasing the flowability by heating the medium, protection against clogging of pipelines
  • Compensation of displacement caused by temperature changes
  • Compensation of displacement related to building settlement
  • Easier mounting of pipelines
  • Noise reduction
  • Custom design expansion joints

    Chamber expansion joints come in all sorts of versions, including flanged expansion joints or weld ends expansion joints. There are many different types of steel they can be made of, depending on working temperature, corrosive properties of a medium and many other technological requirements. The design of the expansion joint is also adjusted to withstand external environment conditions.

    The chamber expansion joint is a unique, non-standard solution, each time custom designed according to technical requirements and exact specifications from the Customer.

Construction of a chamber expansion joint

Outer bellow

Space between the bellows – circulation of a heating agent, of much higher temperature (e.g. oil, water, steam).

Inner bellow – flow of a proper medium

A chamber expansion joint is comprised of two bellows in one inside the other configuration: inner bellow – of smaller diameter and outer bellow – of bigger diameter. A chamber formed between them allows for circulation of the heating agent of higher temperature (e.g. oil, water, steam), which heats up the inner bellow conveying the proper medium.
