Simple unfired pressure vessels designed to contain air or nitrogen - Part 1: Pressure vessels for general purposes

General information

50.60     Dec 8, 2022



European Norm




1.1 This document applies to the design and manufacture of welded, simple unfired pressure vessels manufactured in series, with a single or multiple compartment, here-in-after referred to as vessels.
It only applies to vessels that:
a) include fabrication by welding, but some designs can entail the use of bolts;
b) have a simple geometry enabling simple-to-use production procedures. This is achieved by either
1) a cylindrical part of circular cross section closed by outwardly dished and/or flat ends which revolve around the same axis as the cylindrical part; or
2) two outwardly dished ends revolving around the same axis.
1.2 It applies to vessels which are intended to contain air or nitrogen which are not intended to be fired and which operate within the following constraints:
a) subjected to an internal gauge pressure greater than 0,5 bar;
b) the parts and assemblies contributing to the strength of the vessel under pressure to be made either of non-alloy quality steel or of non-alloy aluminium or non-age hardening aluminium alloys;
NOTE In this document, the use of "aluminium" covers non-alloy aluminium and aluminium alloys.
c) the maximum working pressure is not greater than 30 bar. The product of the maximum working pressure and the capacity of the vessel (PS · V) is greater than 50 bar · l but does not exceed 10 000 bar · l. Below 50 bar · l use of this document is considered to fulfil the requirements of sound engineering practice;
d) the minimum working temperature is not lower than −50 °C and maximum working temperature not higher than 300 °C for steel and 100 °C for aluminium or aluminium alloy vessels.
It does not apply to vessels specifically designed for nuclear use, to vessels specifically intended for installation in or the propulsion of ships and aircraft, or to fire extinguishers.
The document neither applies to transportation vessels nor to vessels which also contain substances other than air or nitrogen which could adversely affect their safety. For vessels to contain compressed air for braking systems of road vehicles and their trailers, see also EN 286-2. For vessels to contain compressed air for braking systems of rail mounted vehicles, see also EN 286-3 and EN 286-4.
1.3 It applies to the vessel proper, from the inlet connection to the outlet connection and to all other connections required for valves and fittings.
1.4 For the purposes of calculations required to be made in accordance with this document, dimensions are in millimetre, pressures are in bar (except otherwise specified), stresses are in newton per square millimetre and temperatures are in degree Celsius.
