Steel Weld Neck Flange DN20 PN100 S235JRG2 EN 1092-1

Steel Weld Neck Flange DN20 PN100 is a highly effective element for aligning and centering pipes, ensuring uniform load distribution. With a nominal pressure of 100 bar and a diameter of 20 mm, this flange guarantees the stability and reliability of the entire piping system in municipal, industrial, and energy networks. Applicable in power and heat supply pipelines, it provides operation in a wide temperature range of -40°C to +450°C.

Billets for collar flanges undergo pre-treatment, including specialized annealing to relieve internal stresses from hot forging. The steel grade, St20 (C20 / S235JRG2), fully complies with GOST 12820-80 and EN1092-1, ensuring product quality and reliability. CNC machining guarantees dimensional accuracy and tight joints. Installation includes collar welding, bolting with tightening control, and the application of spiral wound gaskets with protruding or flat surfaces for a durable, tight connection.
