36 Inch custom Pressure balanced expansion joint

Bellows Systems designs and delivers a 36 Inch Custom Pressure balanced expansion joint to a major aerospace engine manufacturer.

Bellows Systems Inc, recently shipped a 36 Inch custom Pressure balanced expansion joint to a major aerospace engine manufacturer. This pressure-balanced expansion joint will be used in a jet engine test facility in Florida to upgrade existing piping.

36 inch Custom Pressure Balanced Expansion Joint

The project was delivered within 10 weeks from design concept to delivery. As per the client’s requirement, we used Stainless Steel 304 Grade to build this 36-inch x 120-inch Expansion Joint.

A Pressure Balanced Expansion Joint (Elbow type) is normally a double bellows Expansion Joint with a side outlet between the bellows. The ends of the bellows are tied together so that as one bellows compresses due to axial movement, the opposing bellows open an equivalent amount.

Bellows Systems Inc designs and manufactures metal bellows, expansion joints, exhaust systems, and associated products. Our products are used in diverse industries such as Oil and Gas Transmission, Petrochemical plants and Refineries, Power Generation, Automotive, Aerospace and Defense, and many more.

Dual Bellows type universal expansion joints

Dual Bellows type universal expansion joints


Two different dual bellows type universal expansion joints,

  • 36” ID x 41” long with flanges for a compressor station in Texas, CAT GCM – 34 Exhaust.
  • 41” ID x 26” long with weld ends for a refinery in South America.

Dual universal expansion joints are the simplest type of universal expansion joint. They are typically used in low-pressure applications, such as exhaust ducting. They can absorb both axial and lateral movement in the piping.

Exhaust Bellows : Dual Expansion Joint for 825 SGTB Superior Engine

18” Dual Expansion Joint for a 16 cylinder White Superior 825 SGTB Engine

Bellows Systems has been manufacturing exhaust manifolds and exhaust bellows and expansion joints for Cooper-White Superior engines for over 40 years. Our exhaust manifold products cover the entire range of superior engines and include both,

  • Water jacketed (Wet) Manifolds
  • Insulated (Dry) Manifolds

    Our products with robust design have been in maintenance-free service for over two decades. As an example, the wet manifold designs for G825 series engines incorporate 4 ply nickel alloy bellows with liners on the inner jacket. This ensures the expansion joints last the life of the manifold.

    High Temperature piping Expansion Joints

    Hinged and Gimbaled piping Expansion Joints for a Natural Gas Fired Heater

    High-Pressure High-Temperature piping Expansion Joints for a Natural Fired Heater at a US AFB.

    • Design pressure of 1,300 Psi and design temperature of 1,250 F.

    • Hydrotest at 1,900 Psi

    Bellows Systems designed and manufactured one hinged and two gimbal expansion joints for a recent project. The gimbal type expansion joints included one with an external cover and removable insulation.
    The bellows materials included Inconel 718 alloy construction with integral root rings and collars. Hinge and Gimbal structural components included 304 SS and 347H SS.

    Hinged bellows were designed to be capable of 7 degrees of angular rotation at design temperature and pressure.

    Bellows Systems is your go-to source for the standard to the most challenging bellows and expansion joint applications.
