Steel Weld Neck Flange DN100 PN40, with its tapered collar, creates a strong butt welded connection to the pipe. The nominal bore of 100 mm and the ability to operate at 40 bar make this fitting ideal for high-pressure and critical lines, including industrial and power generation facilities.

These collar flanges, made of steel St20 (C20 / S235JRG2), are manufactured according to GOST 12820-80 and EN1092-1 standards using modern hot forging techniques. Plasma-arc and laser cutting equipment ensures high-quality cuts and precise geometry, crucial for tight connections at high pressures.

Suitable for critical connections in the oil and gas and metallurgical industries, these flanges provide excellent tightness and resistance to dynamic loads at temperatures ranging from -40°C to +450°C. Spiral wound gaskets are recommended for optimal reliability in demanding conditions.

Customers can pick up the Steel Weld Neck Flange DN100 PN40 at warehouses in Krakow, Poznan, Warsaw, Lodz, Sofia, Varna, and Plovdiv.
