Expansion joints are an assembly designed to safely absorb sound, expansion, con traction and vibration to ensure expansion jointsthat the application stays in fully working order. When we apply this technique to pipe systems, we brand the term ‘pipe expansion joint’ or ‘bellows’.

These pieces of equipment are used in pipe work where movement, thermal expansion and much more could cause problems. The pipe expansion joints are made up from one or more convolutions, which are designed to move or expand to relieve the stress from the solid pipe. The amount of movement or expansion within the application will determine the number and shape of convolutions required. Expansion joints can be manufactured from a range of different materials, from stainless steel and PTFE, to rubber.

Pipe expansion joints are also designed for other criteria, such as noise absorption, anti vibration, earthquake movement and building settlement. Metal expansion joints have to be designed according to rules.  Pipe expansion joints are used in a number of industries, including; oil, petrochemical and paper industries.

Pipe expansion joints are often manufactured to withstand temperatures from minus 300°F, up to 4000°F, as well as being able to resist at full vacuum or 2000 psig. Expansion joints can be manufactured from a range of different materials aforementioned. Before the introduction of pipe expansion joints, engineers were battling with the task of combating problems regarding thermal expansion, corrosion and abrasive factors that took effect on the functionality of various applications. Fabric joints can be used in a number of applications for turbines and pipelines, which can defend against resistance, heat and a range of other environmental factors.

Pipe expansion joints are crucial components in the pipe technology sector, which serve a huge number of industries. They are used to counterbalance length changes that generally occur in pipelines from temperature changes and can also absorb vibrations. It is a cost effective solution to increase the life span, reliability and costs of many applications through equipment and process management.
