Main use of metal wound gaskets
Jan 22, 2019

The metal-wound gasket with excellent resilience can automatically adjust the pressure thermal cycle and vibration of the pipeline system, especially suitable for occasions where the load is uneven, the joint force is easy to relax, the temperature and pressure are periodically changed, and there is shock or vibration. It is a static sealing original for flanges at valves, pumps, heat exchangers, towers, manholes, hand holes, etc. It is widely used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy and aerospace.


In order to facilitate the installation of the flange pad design, according to the size of the gasket, 2~8 positioning belts are welded on the periphery of the gasket, so that the positioning belt is fastened on the flange hole to prevent the gasket from shifting or falling off during installation. The saving of auxiliary materials and working hours is generally divided into the following types:


The metal wound gasket is made of high-quality SUS304, SUS316 ("V" or "W" shaped) metal strip and other alloy materials and spirally wound with graphite, asbestos, PTFE, non-asbestos and other soft materials. The metal strip is fixed by spot welding at the beginning and at the end. The metal wound gasket is a gasket with good resilience 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 large 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 the load is uneven, the joint force is easy to relax, the temperature and pressure are periodically changed, and there is shock or vibration. Wound gaskets are flanged joints for valves, pumps, heat exchangers, towers, manholes, hand holes, etc.
