TR CU 032 vs the PED Directive: Two Philosophies
Both regulate pressure equipment safety, but one puts risk analysis on the manufacturer and the other prescribes the requirements. What that means in practice.

Pressure equipment certification
Vessels, boilers, heat exchangers and pipelines under TR CU 032 and the PED. The 0.05 MPa line, four categories and the three documents that set the schedule.
Pressure equipment is a regulatory class before it is an engineering one. Under TR CU 032/2013 the line is internal pressure more than 0.05 MPa above atmospheric, and above it a vessel, boiler, pipeline, heat exchanger or fitting is high-risk whatever it is for. The regulation sorts equipment into four categories from pressure, capacity and the hazard group of the medium; categories 1 and 2 declare, 3 and 4 certify, and inspection control attaches to the higher categories. Heat exchangers also fall under TR CU 010 in every case, and the tube side and shell side are assessed separately.
Three documents set the calendar. The Justification of Safety, required by TR CU 032 and TR CU 010 and no other regulation, is written by the manufacturer in Russian and dated inside the design phase. The strength calculation is accepted only when drawn up to GOST 34233.1-2017, GOST 14249-89 and their companions, so a calculation from another system is redone. The technical passport travels with the equipment for life, one per serial number, with different contents for pipelines, boilers and vessels, and foreign manufacturers are the ones caught out by it. PED 2014/68/EU chases the same outcome by a different philosophy, manufacturer risk analysis against prescribed requirements, and there is no mutual acceptance.
The scope has an edge. Main and distribution pipelines for gas and oil are excluded together with their fittings; pipes used outside those systems are argued about by certification bodies. The articles below cover the categories, the vessel guide, each of the three documents, pipes, heat exchangers, the PED comparison and the risks the regulation exists to prevent. Send design pressure, volume and medium and we will name the category and the form.
No articles match that.

Frequently asked questions
Does our PED module H certificate help with TR CU 032?
The engineering behind it does; the certificate itself does not. There is no mutual acceptance, the strength calculation is redone to the GOST standards, and the Justification of Safety and technical passport are new documents. Expect to reissue the file, because a translation of it will not be accepted.
Is a heat exchanger pressure equipment or machinery?
Both. TR CU 010 applies to every heat exchanger and produces a declaration. TR CU 032 applies to the types treated as pressure vessels, shell-and-tube and spiral among them, and can produce a declaration or a certificate, decided separately for the tube side and the shell side.
