What is this standard about?
This is Part 2 in the series of European standards specifying requirements for the design, construction, inspection and testing of unfired pressure vessels made from steels and steel castings as well as additional materials such as cast iron, aluminium and nickel.
The series applies to unfired pressure vessels with a maximum allowable pressure greater than 0.5 bar gauge, but may be used for vessels operating at lower pressures, including vacuum.
These standards are invaluable to those who want to demonstrate compliance with the European Pressure Equipment Directive (the PED).
This second part deals with material requirements for the fabrication of unfired pressure vessels.
Who is this standard for?
Organizations who commission, design, build and maintain pressure vessels. This includes:
- Mechanical engineers
- Pressure vessels designers, and
- Manufacturers and inspectors in:
- Oil and gas
- Petrochemicals
- Process plant
- Energy generation (including nuclear)
Why should you use this standard?
It specifies requirements for materials, including clad materials, for unfired pressure vessels and supports which are covered in BS EN 13445-1 and manufactured from metallic materials.
It is currently limited to steels with sufficient ductility but it is, for components operating in the creep range, also limited to sufficiently creep ductile materials.
This part also specifies requirements for selection, inspection, testing and marking of metallic materials for the fabrication of unfired pressure vessels.
What’s changed since the last update?
- Annual updates have been made as part of the regular updating process in order to ensure the accuracy and usability of the series
- Specifically, this amendment (A3:2018) introduces minor changes to Clauses 1, 2 and 4 plus updates to Annex B and Annex E
