BS EN 13445-1:2014+A2:2018

What is BS EN 13445-1 - Unfired pressure vessels about?

BS EN 13445 is a series of European standards on unfired pressure vessels.

BS EN 13445-1 defines the terms, definitions, quantities, symbols, and units that are used throughout the EN 13445 series and gives general information on the design and manufacturing of vessels under this standard.

BS EN 13445-1 also contains instructions on how to use the standard (Annex A) as well as an index that covers the whole standard (Annex B). This information is aimed to aid users of the EN 13445 series.

It 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.

BS EN 13445-1 can be applied to the following pressure vessels if an account is taken of additional and/or alternative requirements resulting from the hazard analysis and from rules or instructions specific for:

• Transportable vessels
• Items specifically designed for nuclear use
• Pressure vessels with a risk of overheating

Note 1: BS EN 13445-1 is not applicable to pressure vessels of the following types:

• Vessels of riveted construction
• Vessels of lamellar cast iron or any other materials not included in parts 2, 6, or 8 of the standards
• Multi-layered, auto-frettaged or pre-stressed vessels

Who is BS EN 13445-1 - Unfired pressure vessels for?

BS EN 13445-1 on unfired pressure vessels is useful for:

• Pressure vessel manufacturers
• Design engineers
• Research and development facilities
• Quality control personnel

Why should you use BS EN 13445-1- Unfired pressure vessels?

An unfired pressure vessel is a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. BS EN 13445-1 deals with the general philosophy on materials, material grouping, and low-temperature behaviour. It is limited to steel with sufficient ductility and, for components operating in the creep range, sufficient creep ductility.

BS EN 13445-1 gives the rules to be used for design and calculation under internal and/or external pressure. material traceability, manufacturing tolerances, welding requirements, requirements for permanent joints other than welding, production tests, forming requirements, heat treatment, repairs, and finishing operations is also discussed in BS EN 13445-1.

BS EN 13445-1 discusses NDT and other inspection activities including document control, material traceability, joint preparation, and welding. BS EN 13445-1 also discusses rules for material, design, fabrication, inspection, and testing of pressure vessels made from spheroidal graphite cast iron, aluminum, and aluminum alloys, nickel, and nickel alloys.  

Using BS EN 13445-1 you can define the terms, definitions, quantities, symbols, and units that are used throughout the EN 13445 series and give general information on the design and manufacturing of vessels.
