Steel Weld Neck Flange DN65 PN100 is a critical part for the safe operation of various trunk lines, ranging from oil and gas pipelines to water and heat supply systems. It has a 65 mm diameter and withstands pressure up to 100 bar, ensuring system integrity under a wide range of operating conditions and loads.

The manufacturing of these weld neck flanges strictly adheres 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 guarantees product reliability for high-pressure systems.

These flanges are suitable for the chemical industry (with moderately aggressive media), industrial water supply, and compressed air systems. They operate in temperatures ranging from -40 to +450 °C and withstand increased loads. Paronite or spiral wound gaskets are recommended for enhanced sealing.
