Material Characteristics of Graphite Metal Spiral Wound Gaskets:
- Heat-resistant and high-pressure resistant, suitable for high-pressure flanges;
- Provides long-term and reliable sealing;
- Adaptable to operating conditions with fluctuating pressure and temperature standards.
-
Application Areas: Pipe flanges, towers and tanks, pressure vessels, high-speed joint surfaces, high-temperature and high-pressure valves, and covers are generally used for high-temperature and high-pressure steam, gases, and solvents. Sealing for wellhead devices and Christmas trees in the petrochemical industry.
Graphite metal spiral wound gaskets are used in cooperation with bolts with holes at the end of the threaded rod. Spring washers are installed below the nut to prevent the nut from loosening. An open cotter pin is inserted into the bolt hole from the nut groove to prevent the nut from loosening automatically, mainly used in places with impact loads or alternating loads. Spring washers are widely used in load-bearing and non-load-bearing structures of general mechanical products. Their characteristics include low cost, convenient installation, and suitability for continuous installation and disassembly of parts. However, spring washers have low fastening capabilities.
The primary role of the gasket in cooperation with screws and bolts is to fasten. The basic function of the spring washer is to provide strength after tightening the bolt. It enhances the rejection force between the screw, bolt, and material. The metal ring gasket tightens the material during vibration to prevent loosening between the screw, bolt, and material. Simply put, the role of the spring washer is to provide protection. Another function of the spring washer is to form a three-component assembly with cooperating screws and bolts, often used in conjunction with flat washers. The combination of graphite metal spiral wound gasket types and carbon steel non-standard gaskets is widely used in the market. More and more people prefer to use this type.
The classification of graphite metal spiral wound gaskets and their material requirements may affect the application of precision molds. When using them, attention should be paid to the material's excellent properties to ensure that the material meets the application requirements in terms of quality and guarantees the needs in terms of quality and normal functionality.
