Metal spiral wound gasket is filled with metal tape wound with non-metallic material, and the support ring has inner and outer metal rings.

Metal spiral wound gasket is filled with metal tape wound with non-metallic material, and the support ring has inner and outer metal rings. Spiral wound gasket is made of V-shaped metal strips and soft non-metallic fillers through surfacing and spiral winding, and its ends and heads are connected by spot welding. With its excellent compression resilience, it is suitable for sealing points with frequent temperature and pressure changes. Spiral Wound Gasket Support Rings, Internal and External Spiral Wound, Improves Spiral Wound Gasket Handling, Assembly and Versatility. Spiral wound gaskets can be used as static sealing elements such as pipes, valves, pumps, heat exchangers, condensing towers, flat holes in flanges, manholes, etc. Metal gaskets have been widely used in petrochemical, machinery manufacturing, electric power and other fields. Stations, metallurgy, shipbuilding, medical medicine, nuclear power plants and navigation, chemical, power station, metallurgy etc. Special ...

Optimize gasket performance with the correct flange surface

Selecting the correct flange finish is critical to ensuring optimum gasket performance. A fundamental aspect of effective sealing is the level of friction between the flange and gasket surfaces. In fact, flange surface preparation can have a dramatic effect on several key performance factors, including bolted joint tightness, burst resistance, and gasket creep relaxation. Flange finish options range from smooth to jagged and everything in between. As you consider the different options, keep in mind that there is no single best surface finish for all types of gaskets . Different finishes are better suited for different gasket types. How to calculate surface finish? Before choosing a surface finish, it is important to understand two different methods of calculating surface roughness: Arithmetic Average Roughness Height (AARH) Root Mean Square (RMS) AARH is also known as Roughness Average (Ra). This is the most common method of measuring surface roughness: by calculating the average surfa...

Learn about PTFE gaskets

PTFE gaskets are flat gaskets, V-shaped gaskets, piston rings, ball valve gaskets, etc., which are mechanically turned or cut from PTFE rods, tubes, and plates, and have good characteristics such as corrosion resistance, aging resistance and non-conductivity. General purpose piping gaskets are used to seal all types of flanges in chemical process piping, the Style 800 gasket is designed to meet the needs of a wide variety of piping materials and is available in steel, glass lined and fiberglass reinforced plastic (FRP) systems (non-metallic gaskets can be used) ideal standardized gasket material in any application). PTFE pH 0-14 (except molten alkali metal and fluorine under high temperature and high pressure). It can have good mechanical strength between -100℃～100℃. Pressure 10Mpa. Note: When the temperature is lower than -185℃. General-purpose pipe PTFE gaskets can become brittle. Pure general-purpose pipeline PTFE gasket is a clean sealing product that will not pollute any substan...
