The main uses and application range of graphite spiral wound gaskets

Graphite spiral wound gaskets are currently a widely used sealing gasket. They are gaskets with excellent resilience among semi-metallic sealing gaskets. They are made of V-shaped or W-shaped thin steel strips alternately wound with various fillers. They can withstand high temperatures. , high pressure and suitable for use under ultra-low temperature or vacuum conditions. By changing the material combination of the gasket, the problem of chemical corrosion of the gasket by various media can be solved. Its structural density can be made according to different locking force requirements to strengthen the main body. And accurate positioning, the spiral wound gasket is equipped with a metal inner reinforcing ring and an outer positioning ring. The inner and outer steel rings are used to control the compression degree. The surface accuracy of the flange sealing surface in contact with the gasket is not high.

Main uses of Graphite spiral wound gaskets
Metal spiral wound gaskets with excellent resilience can automatically adjust the pressure, thermal cycle and vibration of the pipeline system. They are especially suitable for situations where the load is uneven, the joint force is easy to relax, the temperature and pressure change periodically, and there is impact or vibration. It is a static sealing element for flange joints such as valves, pumps, heat exchangers, towers, manholes, hand holes, etc. It is widely used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy, aerospace and other sectors. In order to facilitate installation in the appearance design of the flange gasket, 2 to 8 positioning straps are welded on the periphery of the gasket according to the diameter of the gasket, and the positioning straps are buckled on the flange hole to prevent the gasket from shifting or falling off during installation. , saving auxiliary materials and man-hours.

Metal spiral wound gaskets are made of SUS304, SUS316 ("V" shape or "W" shape) metal strips and other alloy materials, and soft materials such as graphite, asbestos, PTFE gaskets, and non-asbestos, which are alternately overlapped and spirally wound. , fix the metal strip with spot welding at the beginning and end. Metal spiral wound gaskets are gaskets with good resilience among semi-metallic sealing gaskets. The structural density of metal spiral wound gaskets can be produced according to different locking force requirements, and internal and external steel rings are used to control the degree of compression. Metal spiral wound gaskets The surface accuracy of the flange sealing surface in contact with the sheet is not high. Metal spiral wound gaskets are particularly suitable for situations where the load is uneven, the joint force is easy to relax, the temperature and pressure change periodically, and there is impact or vibration. Spiral wound gaskets are ideal static sealing components for flange connections such as valves, pumps, heat exchangers, towers, manholes, and hand holes.

Graphite spiral wound gaskets application range:
Sealing flange joints of pipelines, valves, pressure vessels, condensers, heat exchangers, towers, manholes, hand holes and other flange joints in petroleum, chemical, metallurgy, electric power, shipbuilding, machinery and other industries.
