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.

48" Diameter, Thick-Wall Expansion Joint for a refinery in Louisiana

Sweco Fab, a division of Piping Technology & Products, Inc., fabricated a 48-inch diameter thick-wall expansion joint for a refinery in Louisiana. The joint was fabricated from carbon steel with a 1/8″ minimum thickness. It is designed for an axial force of 2,500 lbs/in with a 1.15-inch axial deflection and a lateral force of 30,000 lbs./in. with a 0.002-inch lateral deflection.
