Stainless steel seamless concentric reducer DN25 33.7 x 4.5 mm / DN15 21.3 x 3.73 mm 1.4401 / 1.4404 / 316 / 316L

Stainless steel seamless concentric reducer (symmetrical taper), larger side 33.7 × 4.5 mm, smaller side 21.3 × 3.73 mm, steel grade 1.4401 / 1.4404 / 316 / 316L. Theoretical weight per piece: 0.2 kg. A concentric reducer has the shape of a straight cone with an axis symmetrical to both ends — it changes the pipeline diameter without disturbing the flow kinetics of the medium. Used in vertical sections of water, drainage, transfer, chemical, food-grade and sanitary pipework, wherever there is no risk of air pockets or stagnant zones. The seamless construction delivers high pressure resistance and excellent corrosion resistance.

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.
