General characteristics
With stainless steel transitions there is a change in pipeline diameter from a larger to smaller and Vice versa. Produce concentric reducers, they are the same conical — labeled) when both of the diameter of the passage located on the same axis of symmetry. Also produce eccentric reducers. Such transitions profile is a rectangular trapeze line one wall, and the second is the change from one diameter to another.
Manufacturer
Domestic stainless seamless transitions make stamped weld. They are designed for pressure 63−100 ATM. According to T. U. 26−18−38−90 dimensions are specified as follows, for example, 76x57 — 325x273. The length of the transitions should correspond to GOST 17 378−2001 (for steel crossings. Domestic stainless transitions are most commonly made from steel alloy 12X18H10T 08CR18NI10TI or.

Imported stainless steel transitions made from electric-welded pipes, so they have a thinner wall with the same transitional diameters, they have less weight and are not designed for such high pressure. Made of bleached grades: AISI 304, 304L AISI, at least 316 AISI (AISI 316L).
