Product Overview: European Standard PN40 Pressure and P235GH High-Temperature Reliability
Our DN25 PN40 Carbon Steel Flange is a precision component specifically designed for medium-to-high pressure, high-temperature environments within the European standard system. The flange body is forged from premium P235GH Carbon Steel, a material certified under EN10028 and designated for use in pressure vessels and elevated temperature service, ensuring exceptional structural stability under thermal stress.
The flange strictly adheres to the EN1092-1 international specification, while also being compatible with ASTM standards. Its Butt Weld (BW) connection provides the highest structural integrity, and the Raised Face (RF) sealing surface guarantees a reliable, leak-proof seal suitable for the PN40 pressure class. As a **small-bore (DN25) ** flange, it is ideally suited for demanding branch lines and instrumentation piping in chemical, power generation, and oil & gas facilities.
