What is BS EN 12542 - Static welded steel cylindrical pressure vessels design about?
BS EN 12542 specifies requirements for the design and manufacture of static welded steel cylindrical pressure vessels, serially produced for the storage of liquefied petroleum gas (LPG) with a volume not greater than 13 m3 and for installation above or below ground.
Pressure vessels shall be provided with an adequate number of openings to satisfy the need for fittings to meet service requirements. Openings using screwed or flanged connections shall be positioned such that they remain accessible after installation.
Who is BS EN 12542 - Static welded steel cylindrical pressure vessels design for?
BS EN 12542 on the static welded steel cylindrical pressure vessels is beneficial for:
- Manufacturers of pressure vessel
- Individual or organization responsible for the design, fabrication, testing, installation
- Industries such as petrochemical, oil, and gas, chemical and food processing industries
- Private sectors
- Power networks
- Welders
- Testers of ultrasonic, radiography, visual, magnetic particle
Why should you use BS EN 12542- Static welded steel cylindrical pressure vessels design?
A pressure vessel is a container designed to hold gases or liquid at a pressure different from the ambient pressure.
BS EN 12542 calls for the use of substances and procedures that may be injurious to health and/or the environment if adequate precautions are not taken. BS EN 12542 refers only to technical suitability. BS EN 12542 provides guidance on the environmental aspects to be considered regarding equipment and accessories produced for the LPG industry and the following are addressed:
- Design
- Manufacture
- Packaging
- Use and operation
- Disposal
BS EN 12542 assists the user with the pressure used for the calculation of the minimum wall thickness.
Overall, BS EN 12542 is helpful as it provides details on static welded steel cylindrical pressure vessels that can help you out in your business. BS EN 12542 has a group of pressure parts or finished pressure vessels, made consecutively by the same manufacturer using the same manufacturing techniques to the same design, nominal size, and material specifications on the same production machinery and subject to the same heat treatment conditions. The welding consumables can give consistent welds with properties at least equal to those specified for the parent materials of the finished pressure vessel.
What’s changed since the last update?
BS EN 12542:2020 supersedes BS EN 12542:2010, which is withdrawn.
The following main changes have been introduced during the revision of EN 12542:2010:
- A reference to “CEN/TS 16765 LPG equipment and accessories - Environmental considerations for CEN/TC 286 standards” has been added and the existing wording has been amended (including the deletion of environmental references throughout BS EN 12542:2020)
- Annex J Environmental checklist has been deleted
- Inclusion of the use of compensation calculations from EN 13445-3:2014, to reduce the distance between openings or branches
- A new informative Annex J Exterior corrosion protective coating with superior performance against chemical and mechanical attacks have been added
