Описание
This European Standard 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 standard as refrigerating systems as defined in EN 378-1.
This European Standard 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 European Standard 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 European Standard applies to both the mechanical loading conditions and thermal conditions as defined in
EN 13445-3 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 EN 13445-2 and EN 13445-3 or as
specified in this standard. In addition vessels designed to this standard should have a maximum design temperature
not exceeding 200 °C and a maximum design pressure not exceeding 64 bars. Outside of these limits, it is important
that EN 13445 be used for the design, construction and inspection of the vessel. Under these circumstances
it is important that the unique nature of refrigerating plant, as indicated in the introduction to this standard,
also be taken into account.
It is important that pressure vessels used in refrigerating systems and heat pumps of category less than II as defined
in Annex H comply with other relevant clauses of EN 378-2 for vessels.
This European Standard applies to pressure vessels where the main pressure bearing parts are manufactured from
metallic ductile materials as defined in Clause 4 and Annex I of this standard.
This European Standard does not apply to vessels of the following types:
- vessels of riveted construction;
- multilayered, autofrettaged or prestressed vessels;
- vessels directly heated by a flame;
- roll bond heat exchangers.
Festgel werden Anforderungen an Werkstoffe, Konstruktion, Herstellung, Prüfung und Dokumentation für ortsfeste Druckbehälter für Kälteanlagen und Wärmepumpen. Diese ÖNORM umfasst Druckbehälter mit angeschweißten oder angelöteten Bauteilen bis einschließlich Stutzenflansche, Schraub-, Schweiß- oder Lötverbindungen oder bis zu der ersten Schweiß- oder Lötnaht für den Anschluss von Rohrleitungen oder anderen Teilen. Sie gilt für Druckbehälter bis - 1 bar, um die Luftabsaugung des Behälters vor dem Füllen mit Kältemittel zu berücksichtigen.
