The resilient metal wound gasket can perform the pressure thermal cycling and vibration of the piping system.
Automatic adjustment, especially suitable for uneven load, easy to loose joint force, temperature and pressure periodic change, there is shock or vibration of the occasion. valves, pumps, heat exchangers, towers, manhole, hand holes and other flange joints of the original static seal, widely used in petrochemical, machinery, electricity, metallurgy, shipbuilding, medicine, atomic energy and aerospace and other departments.
In the design of flange cushion in order to install conveniently, according to gasket caliber size, in the gasket periphery weld $number a position belt, let the position belt buckle on the flange hole, in case of installing the gasket to shift or fall off, saves the auxiliary material and the work hour. There are several types of the following:
Metal wound Gaskets using high-quality SUS304, SUS316 ("V" or "W"-shaped) metal tape and other alloy materials and graphite, asbestos, PTFE gasket, asbestos and other soft materials alternating overlapping spiral wound, at the beginning and end of the metal tape fixed. Metal wound gasket is the best elastic gasket in the half metal dense pad, the structure density of metal wound gasket can be made according to the requirement of different locking force, and the maximum compaction degree is controlled by internal and external steel ring, and the surface precision of flange sealing surface with wound gasket is not high. Metal wound gasket is particularly suitable for uneven load, easy to loose joint force, temperature and pressure periodic changes, impact or vibration of the occasion. Spiral Wound gasket is the ideal static sealing original of valve, pump, heat exchanger, tower, manhole, hand hole and other flange joints.
