Description
Stainless steel flange, pipe outside diameter 33.7 mm, nominal pressure PN40, hole count 4, steel grade 1.4301 / 1.4307 / 304 / 304L. Theoretical weight per piece: 1.1 kg. Flanges are used wherever a detachable connection of pipeline components is required — with valves, butterfly valves, pumps, filters and other fittings. Compliant with the EN 1092-1 / DIN standard family. The lap-joint (loose) flange slips over a stub end welded to the pipe and rotates freely around the pipeline axis — this simplifies bolt-hole alignment and installation in tight spaces.
Austenitic stainless steel with very good corrosion resistance, good weldability and a wide range of industrial applications. The material is used in machine construction, food industry, chemical industry and general structures.
