Metal spiral wound gaskets utilize alloy or stainless steel strips as the base material, with graphite, asbestos, or PTFE as the filler material, arranged in an alternating spiral winding pattern in "V" or "W" shapes. Due to their high mechanical strength, ease of use, and good compression resilience, they are more suitable for applications involving drastic temperature fluctuations. Strictly speaking, they do not have a unique sealing principle and are used similarly to other gaskets such as rubber gaskets, but they are particularly suitable for situations where other gaskets made of different materials are not applicable.

When purchasing metal spiral wound gaskets, attention should be paid to the following points: Metal spiral wound gaskets are widely used in fields such as petroleum, chemicals, metallurgy, power generation, and shipping. They are crucial components for static sealing in pressure piping, gate valves, pumps, heat exchangers, and other facilities in China. Therefore, the selection and use of metal spiral wound gaskets are of great significance in reducing and preventing leaks, ensuring the normal operation of main equipment and pressure piping. Metal spiral wound gaskets are semi-metallic materials made from multiple materials. As an important sealing product, they have been widely applied. Secondly, the product surface should be free of scars or defects that could affect sealing performance. The welding intervals of the product must be even, with no defects such as unbonded or expanded areas, and the surface should be free of burrs or unevenness. The spacing between the upper and lower sealing surfaces of the main body and the reinforcing ring should be very stable, without any looseness. This ensures greater stability in subsequent applications. As a formal manufacturing enterprise, we have been continuously striving to reduce and avoid the existence of defective products, ensuring the normal operation of main equipment and pressure piping.
