Thick-wall Expansion Joints for Large Diameter Piping Systems
Thick-wall expansion joints may be a cost-effective option for large-diameter piping systems which operate at low pressure. Metals can be selected to satisfy different temperature conditions. The distribution of axial, angular, and lateral forces will be much higher when thick-wall expansion joints are used. We can provide your design engineers with the calculated forces and movements for proper design of the structural members supporting the system. These joints have a long life which justifies the initial investment.
Thick-wall expansion joints are used primarily in heat exchangers and large diameter piping systems where thin-wall expansion joints would not be sufficient. The bellows are typically fabricated from A516 Grade 70 material, with the thickness ranging from 3/16″ to 1″. Other materials are available to meet different temperature requirements.
