Expansion Joints

Metal Expansion Joints
Expansion joints systems are an interesting alternative for pipes and pipelines. Expansion Joints such as these are able to be used in industries such as the oil, paper as well as the petrochemical industries, as well as a lot of other areas.

These are very diverse creations, and quite widely available. They are typically made to standard dimensions, and are able to reach from 1 to 100 metres in diameter and can withstand temperatures from -150°C to 2200°C. They can also resist a full vacuum or 2000 psig.

The market has been totally changed by the introduction of fabric expansion joints, because engineers have a new way to deal with thermal expansion as well as corrosive and abrasive problems.

These fabric joints are able to be used in applications for things such as turbines. Different fabric membranes and designs make it easy for joints to be used for turbines exhaust applications. Distinctive problems arise in the form of GTX, which are difficult applications which present challenges concerning performance and resistance over time. With the aid of fabric joints this can be solved much more easily.

Pipeline systems often use metal bellows to connect pumps and vessels. The folds in the design allows for superior movement in the axial, lateral and angular dimensions. To increase flexibility, other trimmings such as ties, pivots along with other trimmings. These devices have a lifespan, which depends on the shape, material along with the degree to which the connection must be able to bend to.

Metal expansion joints are crucial for pipeline technology as they are needed to counterbalance changes in length, this occurs in pipelines from changes in temperature, aside from this vibrations from pumps engines compressor or turbines are absorbed. Metal expansion joint are a cost effective option to increase the productive life of the pipeline system, making it run better and live longer. Designed to live as long as the system, the metal bellows reduce any sealing problems and the large space needed when dealing with other forms of expansion equipment.

FCCU Expansion joints are available; these need to withstand high temperatures and intense pressures, as well as aggressive environments and significant movements.
Expansion joints are great components and well used for the right application can make things incredibly easier and more efficient.
