Project Description

An expansion joint made from textile fibres is a flexible element. It belongs to the category of the non-metallic expansion joints.
Because of the specific composition of the individual layers, fabric expansion joints are not suitable for installation on lines that carry liquids. They are only suitable when fluids are in a gaseous state.

They can withstand extremely high temperatures, even over 1000°C. Contrary to metal and rubber expansion joints, fabric expansion joints are extremely flexible and their rigidity value is unimportant.

A fabric expansion joint is made of one or more layers of different nature, each of which performs a specific task. Some materials are designed to withstand temperature, others are designed to resist corrosion caused by the process fluid, and others retain pressure.

Overlaying and combining of different layers obtains a stratification that has properties suitable for specific project conditions. It is therefore an extremely versatile component.

What is the use of a fabric expansion joint?

When properly inserted in a pipe system, the fabric expansion joint distorts and adapts to variations in pipe dimensions caused by thermal expansion. It can also be used as a connecting element between equipment and a pipe to which it is connected, in order to avoid “rigid interfaces” that are potentially dangerous for the equipment.
