Steel Weld Neck Flange DN50 PN25 S235JRG2 EN 1092-1

Steel Weld Neck Flange DN50 PN25, with its tapered collar, creates a strong butt welded connection to the pipe. The 50 mm nominal bore and the ability to operate at 25 bar make this fitting optimal for high-pressure and critical lines, including industrial and power generation facilities.

Production of collar flanges from quality steel St20 (C20 / S235JRG2) according to GOST 12820-80 and EN1092-1 starts with careful selection of sheet or round billets. Manufacturing is carried out by hot stamping or forging, ensuring a dense metal structure without defects. This process guarantees high strength and durability, enabling operation under increased loads and meeting the requirements of GOST.

These flanges are suitable for the chemical industry (moderately aggressive media), industrial water supply systems, and compressed air. They operate at temperatures from -40 to +450 °C, withstanding increased loads. The use of vaporite or spiral wound gaskets is recommended to increase tightness.

Steel Weld Neck Flange DN50 PN25 is available for pickup from warehouses in Lodz, Warsaw, Krakow, Poznan, Sofia, Varna, and Plovdiv. Delivery is available throughout Europe, including Romania, Hungary, Croatia, and France. The minimum weight for delivery is one ton. Bending and cutting services are also available.
