What is semi-metallic gasket

A semi-metallic gasket is a type of gasket used in industrial applications where high-pressure and high-temperature sealing is required. It is made by combining metallic and non-metallic materials, creating a gasket that is both strong and flexible.
Semi-metallic gaskets are typically made from a combination of metal layers and filler materials, such as graphite or PTFE. The metal layers provide strength and durability, while the filler material provides flexibility and resistance to fluids and gases.
One of the key benefits of semi-metallic gaskets is their ability to withstand extreme temperatures and pressures. They are commonly used in applications such as oil and gas pipelines, chemical processing plants, and power generation facilities, where high pressures and temperatures are common.
The construction of a semi-metallic gasket typically involves multiple layers of metal and filler materials, which are then compressed to create a tight seal. The number and thickness of the layers will depend on the specific application and the level of sealing required.
Semi-metallic gaskets are available in a variety of shapes and sizes, including oval, round, and rectangular. They can be customized to fit specific applications, and are often used in flange connections, heat exchangers, and pressure vessels.
