DIN EN 1092-1 Dimensions Of PN 250 Flanges

DIN EN 1092-1 PN 250 flanges are a standardized set of flanges designed for use in piping systems where the maximum allowable pressure does not exceed PN 250 (250 bar or approximately 3626 psi). These flanges conform to the DIN EN 1092-1 standard and are commonly used in industries and applications where extremely high-pressure conditions are encountered.

Types of PN 250 Flanges:

Weld Neck Flanges

Slip-On Flanges

Threaded Flanges

Blind Flanges

Socket Weld Flanges

Sizes:

PN 250 flanges are available in a variety of sizes to accommodate different pipe diameters. Common sizes typically range from DN 10 to DN 2000 and beyond, depending on specific requirements and manufacturer capabilities.

Materials:

PN 250 flanges can be constructed from various materials suitable for high-pressure applications. Some common materials include:

Carbon Steel (e.g., ASTM A105)

Stainless Steel (e.g., ASTM A182 F304/F304L, F316/F316L)

Alloy Steel (e.g., ASTM A182 F11, F22)

Duplex Stainless Steel

Super Duplex Stainless Steel

Nickel Alloys (e.g., Inconel, Hastelloy)

Applications:

PN 250 flanges are utilized in industries and applications where extremely high-pressure conditions are encountered. These applications include:

Oil and Gas Extraction and Refining

Petrochemical Plants

Chemical Processing

Power Generation (including Nuclear Power Plants)

High-pressure Industrial Piping Systems
