Pressure equipment for refrigerating systems and heat pumps - Part 1: Vessels - General requirements

This document specifies the requirements for material, design, manufacturing, testing and documentation for stationary pressure vessels intended for use in refrigerating systems and heat pumps. These systems are referenced in this document as refrigerating systems as defined in EN 378-1:2016. The term "refrigerating system" used in this document includes heat pumps. This document applies to vessels, including welded or brazed attachments up to and including the nozzle flanges, screwed, welded or brazed connectors, or to the edge to be welded or brazed at the first circumferential joint connecting piping or other elements. This document applies to pressure vessels with an internal pressure down to -1 bar, to account for the evacuation of the vessel prior to charging with refrigerant. This document applies to both the mechanical loading conditions and thermal conditions as defined in EN 13445-3:2014 associated with refrigerating systems. It applies to pressure vessels subject to the maximum allowable temperatures for which nominal design stresses for materials are derived using
