Performance characteristics:
Wound gasket has good compression performance, good resilience performance, multi-pass seal and certain self-tightening function. It is not sensitive to surface defects on flange compression surface. It does not bond flange sealing surface and can partially eliminate pressure. The influence of changes and mechanical vibrations; it can maintain its excellent sealing performance under various harsh conditions such as high temperature, low temperature, high vacuum, shock vibration and the like.
use equipment:
Flange joints of pipes, valves, pressure vessels, condensers, heat exchangers, towers, manholes, hand holes, etc. in petroleum, chemical, metallurgy, electric power, shipbuilding, gas, nuclear, aerospace, textile, pharmaceutical, machinery and other industries Static sealing part.
Metal wound gaskets are made of standard high-quality "V" or "W" metal strips and other alloy materials and flexible materials such as flexible graphite, special asbestos, PTFE, non-asbestos (Faxkaber seals are not special In addition, non-metallic materials are flexible graphite, other materials need to be stated in the order or inquiry) spirally wound with each other, and the metal strip is wound by spot welding at the beginning and the end. The metal-wound gasket is simple in manufacture, low in price, high in material utilization rate, low in surface roughness of the flange sealing surface, multi-channel sealing effect and good sealing performance, and is an ideal medium-pressure gasket. It is widely used in pipe flanges and pressure vessel flanges of general process materials with high temperature and pressure. It is widely used in pipes, valves and pumps of flange joints of petroleum, chemical, electric power, metallurgy, shipbuilding, papermaking and medicine. The sealing parts of manholes, pressure vessels and heat exchange equipment are ideal static sealing materials.
