Steel Weld Neck Flange DN50 PN100 S235JRG2 EN 1092-1

Steel Weld Neck Flange DN50 PN100 is a key pipeline element, providing a highly reliable and tight connection. This 50 mm nominal bore fitting, designed for nominal pressures up to 100 bar, is ideal for systems requiring high strength and durability, including industrial, municipal, and energy applications.

Collar flanges are manufactured according to GOST 12820-80 and EN1092-1 standards. Certified St20 (C20 / S235JRG2) steel and modern plasma-arc or laser cutting technologies ensure precise part geometry and minimal deformation. Quality control at every stage confirms product reliability for high-pressure systems.

These flanges are applicable in power and heat supply pipelines, operating within a wide temperature range of -40°C to +450°C. Mounting involves collar welding, bolted fastening with controlled tightening, and spiral wound gaskets (with protruding or flat surfaces) for a durable, tight seal.
