Metallic Expansion Joints

Metal pipe 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 a pipe expansion joint must be restrained by the use of tie rods, hinges or gimbal while allowing the bellows to move through its design deflections.

Fabric Expansion Joints

Fabric expansion joints perform a function of compensating for duct misalignment and duct thermal growth typical in power plants and other ducting systems. Fabric expansion joints are found wherever there is a need to convey hot media in low pressure applications such as “in flowing air” and “out flowing gas” in large combustion processes.

Rubber Expansion Joints

Rubber pipe expansion joints are designed to absorb minor misalignments and offsets in piping systems. Engineered for excellent chemical and abrasion resistance, they handle higher pressures than standard metal expansion joints while minimizing the risk of sediment buildup.

Duct Work

U.S. Bellows provides custom designed expansion joints in duct work and fabricated duct work assemblies. The assemblies may include fabricated elbows, tees, and straight sections of duct work, in carbon steel or stainless steel, and in diameters of 42″ or larger. The duct sections can include fabric or metallic expansion joints and can be rectangular or round.
