Transition stainless steel f42 / f21

Stainless steel transition f42 / f21 is a part of the pipeline system that connects two different diameters of pipes, fittings or equipment.

The steel from which the transition is made - AISI 304, is most often used in the food industry, chemical, in the production of alcoholic and non-alcoholic beverages, due to the durability of the material. It contains from 18% to 19% chromium in its composition and 8-10% nickel. It is a food grade austenitic stainless steel with a low carbon content, mainly in demand in the food industry and in oxidizing environments. It can be used at low concentrations of strong acids (nitric, perchloric, hydrochloric, sulfuric) and at low temperatures, as well as at medium temperatures of weak acids (malic, acetic, citric, lactic). In Ukraine, the analogue is steel grade 08X18H10.

Also, this transition can be made of steel AISI 316, this is an improved version of food steel, which contains 2.5% molybdenum and has an increased amount of nickel up to 14%, which gives it additional corrosion resistance in oxidizing environments. For example, boiling 20% ​​phosphoric acid, sulfuric acid at a certain concentration and temperature, sulfur dioxide, hot organic acids. Most commonly used in medicine and pharmaceutical industries. AISI 316 steel at high temperature has better physical and mechanical properties than AISI 304.

There are two types of transitions:

Concentric (conical)

Eccentric

Concentric transition - mainly used in cases where it is necessary to connect two vertical sections of the pipeline system.

Eccentric transition - most often used when it is necessary to connect two sections of the pipeline system in a horizontal position, since it is the eccentric transition that will not affect the speed of passage of the working medium in the pipe. This is not a definitive rule, but it is most often used.
