DIN EN 1092-1 Dimensions Of PN 400 Flanges

DIN EN 1092-1 PN 400 flanges are a standardized set of flanges designed for use in piping systems where the maximum allowable pressure does not exceed PN 400 (400 bar or approximately 5800 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.

Here's detailed information about DIN EN 1092-1 PN 400 flanges:

Types of PN 400 Flanges:

Weld Neck Flanges

Slip-On Flanges

Threaded Flanges

Blind Flanges

Socket Weld Flanges

Sizes:

PN 400 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 400 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)
