Steel Weld Neck Flange DN300 PN40 S235JRG2 EN 1092-1

Steel Weld Neck Flange DN300 PN40 is a critical component for the safe operation of various trunk lines, ranging from oil and gas pipelines to water and heat supply systems. It has a diameter of 300 mm and withstands pressures up to 40 bar, ensuring system integrity under a wide range of operating conditions and loads.

These collar flanges are manufactured from St20 (C20 / S235JRG2) steel according to GOST 12820-80 and EN1092-1 standards. The manufacturing process involves hot stamping and forging to achieve high strength and metal density. CNC machining ensures precise dimensions and surface roughness.

These flanges are suitable for power and heat supply pipelines, operating within a wide temperature range of -40°C to +450°C. Installation involves collar welding, controlled bolt tightening, and the use of spiral wound gaskets with protruding or flat surfaces for a durable, tight seal.

Steel Weld Neck Flange DN300 PN40 can be purchased cost-effectively with self-pickup options available from warehouses in Lodz, Warsaw, Poznan, Krakow, Sofia, Varna, and Plovdiv. Delivery of one-ton batches or more is available throughout Poland, Bulgaria and the EU. Additional services include rolled product bending and cutting.
