What kind of seal is typically used in pressure piping to ensure leak proof connections?

Gasket seals and o-ring seals are commonly employed in pressure piping systems to create leak-proof connections, particularly at joints and flanged connections. The materials used for these seals can vary, including rubber, silicone, and other compounds that are designed to withstand specific pressures and temperatures.

Gasket seals work by compressing between two surfaces when bolted together, thereby filling any voids and preventing the escape of fluids. O-ring seals, which are circular and fit into a groove between two parts, rely on compression to achieve a tight seal. Both types are effective in providing a barrier against leaks in various piping systems.

The choice of gasket or o-ring typically depends on the type of fluid being transported, the pressure rating of the system, and the environmental conditions. This adaptability makes them a standard solution for ensuring integrity in pressure piping.

While other sealing methods like thread sealants, mechanical seals, and welded joints can also be utilized in specific applications, they may not always provide the same ease of installation or adaptability as gaskets and o-rings in retaining pressure without leaks.
