EN1092 stainless steel flanges are produced based on the European Standard EN 1092-1 for circular flanges. They are used to join pipes, valves, and other components in a piping network, providing a leak-proof seal. Predominantly used in European markets, these flanges are suitable for industries like petrochemical, food processing, and pharmaceuticals, where adherence to European standards is essential for regulatory compliance and system compatibility.

Petrochemical companies including ESSO, SHELL, APA, API, WOODSIDE, EXXON MOBIL, Chevron, Bechtel all have specialist requirements. These can be supplied in a stunning range of materials and configurations.
This is a flange made from stainless steel. Most standards specify a range of materials the flanges can be manufactured from including Stainless Steel. Stainless steel is a generic classification for steel that has a varied resistance to corrosion. Mostly these materials have a high Nickel and Chromium content.
The most common stainless steels are:
These stainless steels require specific manufacturing techniques and heat treatment to achieve the corrosion resistance ability.
The material used to manufacture the flange is chosen specifically to cope with the fluid being transported and the environment.
Sizes and Specifications grades/shapes
List and briefly describe common applications in various industries:
Stainless flanges are used when either the process demands it or the environment is corrosive or both. Sometimes stainless flanges are used because they look terrific such as in engine rooms in boats where everything is kept clean and shiny.
Stainless flanges are always more expensive than the carbon steel variant. It comes down to corrosion resistance and cost, and in some cases, presentation.
A stainless flange from A240 2205 or A182 F51.
Use 316 where more corrosion resistance is required and the extra cost is justified.
Stainless flanges are welded to the stainless pipe providing a corrosion resistant joint that can be bolted to a valve or more piping.
Pressure ratings of flanges are found in the standard applicable to the flange being used. Additional standards mostly include temperature derating charts so the capability of the flange to withstand pressure is documented as the temperature increases. Generally, the ranges are pressure dependent, so AS4087 PN 16 means 16 bar and ASME B16.5 300 lbs is indicative of the pressure withstood.
Yes, it is OK to bolt stainless steel flanges to carbon steel flanges.
