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.

What are Tie rods? Why do we need them?

What are Tie rods? Why do we need them?

Tie rods are devices, in the form of rods or bars that are attached to the expansion joint assembly whose primary function is to continuously restrain the full bellows pressure thrust during normal operation while permitting only lateral deflection.

Angular rotation can be accommodated only if 2 tie rods are used, located 90 deg opposed to the direction of rotation.
