Where should I use a universal expansion joint in piping?

Universal expansion joints are typically used in z-bend or l-shape pipe arrangements where the expansion joint allows for lateral motion

How long should a universal expansion joint be?

The length of a universal expansion joint is dependent upon the amount of lateral motion to be absorbed by the expansion joint. ...Continue Reading

Can you use a tied expansion joint in the exhaust of a gas turbine application?

Yes, a tied expansion joint is a correct application for tied expansion joints to eliminate pressure thrust on the turbine exhaust nozzle.

How do you decide on the number of tie-rods in a universal expansion joint?

The number of tie-rods on a universal expansion joint is calculated according to the amount of pressure thrust that the particular ...Continue Reading

Do hinged expansion joints have to be designed for pressure thrust?

Yes, hinged expansion joints do need to be designed to accommodate for pressure thrust.

Why do expansion joints have one loose flange?

Expansion joints have one loose flange when specified to facilitate the alignment of flanges on the piping system during installation.

Why is the annealing of stainless steel bellows required?

We do not recommend the annealing of stainless steel bellows because the bellows strength increases while decreasing the cycle life.

When should you replace metal bellows expansion joints?

Metallic expansion joints should be replaced if they are leaking or can simply be replaced on a scheduled maintenance program in ...Continue Reading

How common is it to use steel expansion joint in and out of centrifugal pump?

What will happen if bellow thickness is increased in expansion joints?

If bellow thickness is increased, then the bellows spring rate will increase substantially.

Where can I find a metal expansion joint slide show?

You can find a slide show on an introduction to U.S. Bellows that covers a wide variety of metallic expansion ...Continue Reading

What are unreinforced bellows?

Unreinforced bellows do not have any external type of reinforcement such as root rings or equalizing rings.

What are gimbal expansion joints?

The gimbal expansion joint is basically the same as the hinge type, except that instead of being limited to deflection in only ...Continue Reading

How thick is an expansion joint?

Expansion joint thickness can vary from .010 inches to .125 inches thick depending upon the design requirements for your application.

What is the effective diameter of the bellows?

The effective diameter of the bellows is the mean diameter of the convolutions.

How does a pressure balanced expansion joint work?

How Does a Pressure-Balanced Expansion Joint Work? In complex piping with delicate equipment, managing internal pressure thrust is as vital ...Continue Reading

What is a metallic expansion joint?

A metallic expansion joint device is used to absorb thermal movement. It is generally fabricated from stainless steel or other high ...Continue Reading

Where should we use carbon steel expansion joints?

We typically only use carbon steel material for the bellows rectangular expansion joints which are installed in duct systems. Round ...Continue Reading

How much expansion can a flanged and fluid expansion joint accommodate?

Flanged and flued expansion joints can take minimal amounts of axial motion due to the thickness of the flanged and flued ...Continue Reading

What is a flange on an expansion joint?

The flange on an expansion joint can be one of the end connections to allow for connection to the pipe in the ...Continue Reading
