Steel Weld Neck Flange DN400 PN25 is a welded steel part designed for butt welding with pipes, guaranteeing a strong and durable connection. It has a nominal bore of 400 mm and is designed for operation under pressure up to 25 bar, meeting strict industrial standards. It is ideal for systems with slightly aggressive media and low pressure, such as agriculture, drainage, and non-critical chemical applications. The operating temperature range is -30 to +300 °C. The use of vapor or elastomeric gaskets with flat or protruding sealing surfaces facilitates installation and increases reliability.

These flanges are manufactured from St20 (C20 / S235JRG2) steel according to GOST 12820-80 and EN1092-1 standards. Quality control is implemented at all production stages, from raw material selection to final hydro-testing. Modern hot forging and forging technologies ensure optimal metal structure and product durability for high-pressure systems. This product finds application in the oil and gas, chemical, food, and power industries.
