Description
Stainless steel flange, pipe outside diameter 21.3 mm, nominal pressure PN40, hole count 4, steel grade 1.4401 / 1.4404 / 316 / 316L. Theoretical weight per piece: 0.8 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 blind flange terminates a pipeline run and provides a removable closure — used for inspection access, pressure testing or as a permanent seal on standby branches.
Grade 1.4404 / 316L is an austenitic stainless steel with enhanced corrosion resistance, particularly in more chemically aggressive environments. Thanks to its molybdenum content, this grade offers better corrosion resistance than steel 1.4301 / 304. The material is used in the chemical, food, marine, pharmaceutical industries and in installations and equipment exposed to moisture, chlorides and other corrosive agents.
