Steel Weld Neck Flange DN40 PN63 S235JRG2 EN 1092-1

Steel Weld Neck Flange DN40 PN63 is a crucial component for maintaining the safety and integrity of various pipeline systems, ranging from oil and gas transport to water and heat supply. With a 40 mm diameter and a pressure rating of up to 63 bar, this flange ensures system integrity under a wide range of operating conditions and loads.

The flanges are manufactured from St20 (C20 / S235JRG2) steel, compliant with GOST 12820-80 and EN1092-1 standards, ensuring product quality and reliability. Blanks undergo pre-treatment, including a specialized annealing process to eliminate internal stresses resulting from hot forging. CNC machining guarantees precise dimensions and tight joints.

These flanges are suitable for power and heat supply pipelines, operating within a temperature range of -40°C to +450°C. Proper installation involves collar welding, controlled bolt tightening, and the use of spiral wound gaskets with either protruding or flat surfaces to create a durable, leak-proof connection.
