Types of Metallic Expansion Joints

October 6th, 2010 Comments off

U.S. Bellows offers all types of metallic expansion joints. Each type has advantages and limitations that can provide flexibility, load reduction, structural integrity and reliability required in a piping system.

Metal expansion joints can withstand the design temperatures and pressures, as well as provide the capacity necessary to absorb thermal growth of the piping system. The thermal movement required can be axial, lateral or angular. In some cases, the pressure thrust of an expansion joint must be restrained by the use of tie rods, hinges or a gimbal while allowing the bellows to move through its design deflections.

Refractory Lining

The in-line pressure balanced expansion joints were manufactured for a clean fuels project in India. They are fabricated with Inconel 625 LCF bellows and ASTM A516 GR 70 carbon steel was used for the shell. The inside is lined with insulating and abrasion resistant refractory. The expansion joints were pressure tested with air at 15 PSIG prior to shipment.
