Metal wound gaskets are divided into four forms
Oct 26, 2018

    The metal wound gasket is formed by continuously winding the V-shaped or W-shaped metal strip and the non-metallic strip without any overlap, and the metal strip is fixed by spot welding at the beginning and the end.

    Expanded graphite has the advantages of high temperature resistance, corrosion resistance, softness and good resilience. In the series of wound gaskets, its use temperature is high. Metal wound gaskets are best suited for use in applications where temperature is alternating. Metal-wound gaskets are static sealing components for flange joints such as pipes, heat exchangers, and tower troughs. Metal-wound gaskets are widely used in petroleum, chemical, electric power, shipbuilding, and steel industries. Especially in high temperature and high pressure steam, the hot and cold temperature difference is most suitable for use. It has good compression resilience and is suitable for sealing parts with severe temperature and pressure alternating. It is a static sealing element for flange joints such as pipes, valves, pumps, heat exchangers, towers, manholes and hand holes. Widely used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medical energy and aerospace and other departments. We can produce according to ANSI, APL, DLN, JPL, BS and other standards, or specify the requirements by the user. The use pressure is less than or equal to 25Mpa. If the gasket is used on the heat exchanger, we generally recommend a stainless steel wire inner ring with a diameter of 3.2M. The narrow band material is the same as the steel strip, and the narrow strip type is divided into the adhesive type or the coated type. If the gasket requires a color code, please specify.

    Maximum operating temperature: oxidizing gas: 550 ° C Non-oxidizing gas: 800 ° C Maximum operating pressure: 420 kgf / cm * cm

    1. Metal wound gaskets are divided into four types: basic type, gaskets for grooved flanges, inner rings, gaskets for embedded concave and convex flanges, inner rings, for smoothing Gaskets for flat welded flanges, inner and outer rings, gaskets for smooth butt weld flanges

    2, commonly used materials

    A steel strip: 304, 1Cr18Ni9T (321), 316, 316L, etc.

    B ring material: low carbon steel, oCr13, oCr18Ni9, 304, 316, 316L, etc.

    C Non-metallic tape: flexible graphite, special graphite, polytetrafluoroethylene, asbestos paper.
