Steel Weld Neck Flange DN40 PN100 S235JRG2 EN 1092-1

Steel Weld Neck Flange DN40 PN100 is a highly effective element for aligning and centering pipes, ensuring uniform load distribution. It guarantees the stability and reliability of the entire piping system in municipal, industrial, and energy networks with a nominal pressure of 100 bar and a diameter of 40 mm.

The production of these collar flanges begins with selecting certified steel St20 (C20 / S235JRG2) according to GOST 12820-80 and EN1092-1. Blanks are formed by hot stamping and forging to ensure maximum metal density and the absence of defects. Mechanical processing on modern CNC equipment increases dimensional accuracy and seal surface quality.

These flanges are applicable in power and heat supply pipelines, providing operation in a wide temperature range of -40°C to +450°C. Installation includes collar welding, bolting with tightening control, and the use of spiral wound gaskets with protruding or flat surfaces for a durable, tight connection.

Steel Weld Neck Flange DN40 PN100 can be purchased from UTMK warehouses in Lodz, Warsaw, Krakow, Poznan, Sofia, Varna, and Plovdiv. Delivery is available throughout Poland and other EU countries, including Moldova and France. UTMK also offers bending and cutting of rolled products as additional services.
