Expansion bellows which are made of various materials such as stainless steel, nickel alloys and other metal alloys that are used to control the thermal expansion due to overheat in the piping systems. These expansion bellows absorb the pipe motions and vibrations thereby keeping your pipes and exhaust system safe and efficient.

Stainless steel is the most commonly used material in expansion bellows as they offer heat resistance even at blazing temperature. They have anti-corrosive and ant-oxidation properties, high endurance and strength for high temperature absorption which is essential in the piping systems.

In addition, there are other materials for bellows expansion joints like

• Hastelloy
• Copper Alloys
• Brass
• Aluminium
• Titanium
• Cobalt Alloy
• Nickel Alloy
• Monel

The stainless steel expansion bellows and stainless steel expansion joints are approved by prestigious national and international authorities like

• American Bureau of Shipping (ABS)
• Water Regulations Advisory Scheme (WRAS), FDA & ACS.
• Lloyds Register of Shipping
• Det Norske Veritas (DNV)

There are various movement that are caused in the piping systems which results due to high temperature.

It prevents the following movement:

Axial movement:

As the bellow compressed, the axial movement is evident, and it is a typical movement that occurs parrel to the centre line of the bellow.

Lateral movement:

Any movement that is perpendicular to the axis of the bellow is the lateral movement and bellows does its best to prevent the deflection caused in the pipe.

Angular movement:

Any movement which results in the rotation of the bellows and at times bending as well. The bellow can be useful with its angular motion.

The thickness is usually 3.2 mm or 0.125 inches and more. They come in single convolution with multiple plys and it comes in both Lens model and Flanged model

Bellow expansion joints are a complete unit comprising of expansion bellows, external fittings and liners. They are used in pipes which are installed in oil & gas, marine, construction and other general industries where the pipes exhibit blazing heat due to its ongoing operations. These pipes tend to get create catastrophic consequences due to high pressure and soaring temperature readings.

A complete unit which has a expansion bellow and end fitting is called a expansion joint. The expansion joints can be customized with the size, liners, outer covers, thickness depending on your requirement.

Bellows is the material with which an expansion joint is completed, and it expands to adjust and suit the temperature fluctuations.
