In terms of product introduction, there is generally a maintenance requirement associated with it. If we understand how to maintain the product, it will无形中 enhance its service life and operational characteristics. This is equally true for hardware accessories. On the one hand, we see D-shaped metal spiral wound gaskets everywhere in household products.
High-quality alloy materials such as SUS304 and SUS316 ("V"-shaped or "W"-shaped) metal strips, as well as flexible materials like graphite, asbestos, polytetrafluoroethylene, and asbestos-free materials, are spirally wound together, with the metal strip welded and fixed at the beginning and end. The application parameters of metal spiral wound gaskets include the application pressure of the gasket index: ≤ -196℃ to 700℃ (reducing materials do not exceed 600℃); preload pressure: Y = 70.0 ± gasket index.
Graphite metal spiral wound gaskets are suitable for heat exchangers, pressure vessels, pumps, valves, and flange face sealing, but their rebound elasticity is limited. Steel jacketed gaskets refer to composite gaskets where the internal non-metallic materials (such as soft graphite polytetrafluoroethylene, asbestos rubber sheets, ceramic fibers) are wrapped with metal plates using specific cold processes. Based on the gasket segment, they are generally divided into flat-jacketed and corrugated-jacketed types.
They are traditional sealing gaskets suitable for heat exchangers, pressure vessels, pumps, valves, and flange face sealing, but their rebound elasticity is limited, requiring a flat flange surface and high tightening force to achieve good results. Methods such as 304 stainless steel asbestos-covered gaskets and stainless steel graphite composite gaskets can be composed of different materials.
Metal spiral wound gaskets are of good quality and safe to purchase. Metal spiral wound gaskets are a commonly used sealing gasket made of thin steel strips and various fillers, which are semi-metallic. They are heat-resistant, high-pressure resistant, and suitable for standard applications at low temperatures or in vacuum conditions.
