Graphite Liner

The stainless steel inner and outer ring metal wound gasket is composed of a basic metal wound gasket and an inner and outer ring made of a steel plate, and the inner and outer rings are used to strengthen the pressure and prevent the winding from loosening. The inner and outer rings are available in different materials. Metal wound gaskets are available in four forms: basic metal wound gaskets, metal wound gaskets with inner rings, metal wound gaskets with outer rings, and metal wound gaskets with inner and outer rings. Applications: Pipes, valves, pressure vessels, condensers, heat exchangers, towers, manholes, hand holes, etc. in petroleum, chemical, metallurgy, electric power, shipbuilding, machinery and other industries.

We can produce according to ANSI, API.DIN.JIS, JPI, BS and other standards, or specify the requirements by the user. Use pressure ≤ 25Mpa.

If the gasket is used on a heat exchanger, we generally recommend a stainless steel inner ring with Φ3.2. The narrow band material is the same as the steel strip, and the narrow strip form is divided into a paste type or a cladding type.

If the gasket requires a color code, please specify. Metal wound gaskets are made of high-quality SUS304, SUS316 ("V" or "W") metal strips and other alloy materials and spirally wound with soft materials such as graphite, asbestos, PTFE, and non-asbestos. The metal strip is fixed by spot welding at the beginning and the end.

The metal wound gasket is a resilient gasket in the semi-metal gasket. The structural density of the metal wound gasket can be made according to different locking force requirements, and the inner and outer steel rings are used to control the maximum compression degree. The surface accuracy of the flange contact surface of the sheet contact is not high.

Metal-wound gaskets are especially suitable for applications where load is uneven, joint force is easy to relax, temperature and pressure change periodically, and there is shock or vibration. The wound gasket is a static seal original for the flange connection of valves, pumps, heat exchangers, towers, manholes, hand holes, etc.

Application range of metal wound gaskets: sealing of flanges, pipes, valves, pressure vessels, condensers, heat exchangers, towers, manholes, hand holes, etc. in petroleum, chemical, metallurgy, electric power, shipbuilding, machinery and other industries.
