Stainless Steel Flange Features Under GOST 18120 standard
● Material: Stainless steel flange is made of stainless steel material, with excellent corrosion resistance and high temperature resistance. Common stainless steel materials include A182F304/304L, A182 F316/316L, etc. These materials can meet the requirements of different media and temperature conditions.
● Size and pressure rating: The GOST 18120 standard specifies the size and pressure rating of stainless steel flanges to ensure the compatibility and sealing performance of the flanges with the piping system. Flanges of different sizes and pressure grades are suitable for different piping systems and use cases.
● Structure form: The structure of stainless steel flange is various, including flat welding flange, butt welding flange, loose sleeve flange, etc. These structural forms can meet different connection requirements and piping system requirements.
● Sealing performance: The GOST 18120 standard has strict requirements for the sealing performance of stainless steel flanges. The sealing surface of the flange is usually in the form of a flat, convex or mortising surface to ensure a close fit with the gasket and a good sealing effect.
Application And Precautions
1. Application: Stainless steel flanges under the GOST 18120 standard are widely used in pipeline systems in petroleum, chemical, natural gas and other industries. These systems are often subjected to high pressures and corrosive media, so stainless steel flanges with excellent corrosion resistance and high strength are needed to ensure system stability and safety.
2. Note: When installing and using stainless steel flanges, the following points need to be noted:
Ensure the matching and sealing performance of the flange to the piping system.
Select the appropriate gasket material to ensure a good sealing effect.
Perform regular inspection and maintenance of flanges to identify and deal with potential problems in a timely manner.
