Interpretation and application of metal corrugated gasket standards

1. Introduction to the standard
Metal corrugated gasket is a seal used for mechanical connection. Its main function is to fill and distribute the force of fasteners to prevent loosening and leakage. In international standards, metal corrugated gaskets are mainly specified by JIS, GB, DIN and other standards.
Among them, JIS G3522-1991 standard specifies the technical conditions and material performance requirements of metal corrugated spring steel wire, involving standard parameters such as materials, dimensions, tolerances, and mechanical properties used by metal corrugated gaskets. GB/T 1235-2012 standard specifies the categories, specifications, shapes, thicknesses, materials, etc. of metal corrugated gaskets, and is a standard document applicable to the Chinese mainland market. DIN 2690 standard is the corrugated gasket standard specified by Germany, which has the typical characteristics of German industrial products.
2. Application scenarios
Metal corrugated gaskets are widely used in hydraulics, pneumatics, chemicals, automobiles, metallurgy and machinery. Their specific application scenarios include the following aspects:
1. Pipeline connection: Metal corrugated gaskets can be used for pipeline connection, which can effectively prevent loosening or leakage at the pipeline connection.
2. Vehicle manufacturing: Metal corrugated gaskets can play an important connection role in the hydraulic system and pneumatic system of the vehicle.
3. Shipbuilding: Metal corrugated gaskets can be used for the connection of hydraulic pipelines, pneumatic pipelines and air-conditioning pipelines in ships.
4. Machine tool manufacturing: Metal corrugated gaskets can be used as gaskets for fasteners in machine tools to evenly distribute the force of fasteners on the contact surface, making the fasteners more secure.
