Calculator for calculating the category of equipment for TR CU 032/2013

In the process of certification of equipment for compliance with the requirements of TR CU 032/2013 “On safety of equipment operating under excessive pressure”, it is required to determine the category of equipment according to the above document.

Automatically calculate the category of equipment under the technical regulations using our calculator.


There are groups 1 and 2 for the working environment:

Group 1: includes working fluids consisting of flammable, oxidizing, combustible, explosive, toxic and highly toxic gases, liquids and vapors in a single-phase state, as well as their mixtures;

Group 2: include all other work environments that are not assigned to group 1;



Attention! In accordance with Annex 1 to the TR CU 032/2013, the category of equipment designed for operation with a design temperature above the transition creep temperature of the metal is increased by 1 (except for the 4th category). The creep transition temperature is:

400 ° C — for carbon and low-alloyed silicon-manganese steels;

450 ° C — for low-alloyed chrome-molybdenum and chrome-molybdenum-vanadium steels;

525 ° C — for doped high-chromium martensitic class and austenitic steels;

575 ° C — for alloys on an iron nickel and nickel basis.
