Pipe Bellows

Pipe bellows are sometimes known as metal bellows expansion joints. Pipe bellows are a significant part of the expansion joint. A rubber expansion joint can absorb vibration misalignment and handle axial and limited lateral movement. A metal expansion joint uses bellows in the pipe system. The metal bellows handle thermal growth and pressure thrust. When a piping system gets warm, the thermal dynamics associated with the piping material will grow (metal expansion). The pipe bellows are required to compress and protect the system from damage.

A pipe bellows can consist of several convulsions and are sometimes layered. The layers are called plys. The plys help lesson loads on structures and redundancy to the pipe bellows system. The cycle life may also increase with different materials other than carbon steel. We have Exotic alloys such as Inconel, hastolly, and chrome-moly that could help. Consider pressure thrust when designing a system with pipe bellows.

To call pipe bellows a flexible bellow, maybe a stretch. That is an expansion joint joke or pun. Expansion Joints consist of metal or rubber. A different type of expansion joint is used in concrete to expand pouring foundations, sidewalks, streets, and driveways. The concrete exposition joints have nothing to do with pipe bellows. Instead, expansion joints are rolled or hydra formed, with flanges and weld end.

On request, Vanstone flanges can be to enable easier installations. For example, a Vanstone flange in the pipe bellows pipe system allows the flange to swivel. The rubber pipe bellows can have single bellows or several arches. Rubber piping bellows joints are also known as non-metallic.

They can absorb vibration and be a noise reducer. Some applications are in power plants, wastewater, refineries, and pulp and paper.

The rubber pipe bellows consist of many elastomers, including buna, natural rubber, EPDM, butyl, and Teflon. These fabrics can be woven nylon, bonded with wire-like how a tire is made.

Why use a bellows in a piping system. Often ball valves operate in the same piping system. In addition, duplex basket strainers assist with temporary strainers in keeping the pipeline clean.

The pipe bellow number one function protects the equipment and ancillary parts of the process.

The pipe bellows system is expansion joints installed to absorb vibration and shock. The primary function of the expansion joint is to compensate for thermal growth and misalignment. A ball joint also helps with vibration.
