About Thermosel

The Thermosel name has been synonymous with expansion joints throughout the industrial world for over 50 years. Thermosel metallic expansion joints were exclusively designed for the first British nuclear power stations in the early sixties. Today Thermosel's wide range of expansion joints and applications are widely used in a variety of industries.

Our expansion joints are manufactured from various grades of stainless steel, and a wide variety of nickel alloys depending on their working environment. The bellows convolutions are produced by hydraulically forming or mechanically rolling the desired profile from a tube which consists of one or more plies of material. After forming, end connections are welded to the bellows, and various types of restraint devices added to control the amount and direction of movement can be fitted during the production process if desired. In most applications internal sleeves are incorporated to streamline the flow and protect the convolutions.
