Definition - What does Compression Gasket mean?
A compression gasket is a ringed device that can be made of several types of material, in a variety of cross sections, which serves to secure a tight seal between two pipe sections (e.g., “O” rings). Compression gaskets are used to seal a joint between two mating surfaces. It is important to seal joints between pipes in trenchless construction or rehabilitation to ensure that no leakage occurs when the pipe is under pressure. Compression gaskets are therefore critical components of any pipeline.
Trenchlesspedia explains Compression Gasket
Compression gaskets can be used in new installations or in conjunction with cured-in-place repair operations so that the pipeline under repair is completely sealed. Gaskets prevent pressurised product from escaping a pipe or to prevent ground water from ingressing into the pipe if the pipeline is not under pressure. The technology associated with the manufacture of compression gaskets has improved over the years. Originally, asbestos was a popular choice of material but this has changed due to the negative health effects of asbestos exposure. New materials and techniques are constantly being developed to improve the sealing of underground piping systems.
