What is BS EN 13371 - Cryogenic vessels about?
BS EN 13371 specifies the minimum requirements for the design, manufacture and testing of couplings for cryogenic service to be used for temporary connecting of flexible hoses to cryogenic vessels at the following operating conditions :
- design temperature range from - 270 ° C to + 65 ° C
- maximum nominal pressure : 80 bar
- nominal size (DN) from 10 to 100
Permanent connections such as flanges and unions are not covered by BS EN 13371.
It is intended that the couplings should be designed, tested and marked for service at one of the generally accepted pressure e.g. PN 40. Couplings can then be selected with a PN equal to or greater than the maximum allowable pressure (PS) of the equipment for which they are to be used.
Who is BS EN 13371 - Cryogenic vessels for?
BS EN 13371 on Cryogenic vessels is useful for:
- Valves and cryogenic equipment manufacturers
- The oil and gas industry
- The water and steam industry
- The petrochemical industry
- The chemical industry
Why should you use BS EN 13371 - Cryogenic vessels?
A cryogenic valve is often designed to respond to high pressure by opening the valve, allowing gas or other media to flow freely through it. Cryogenic valves are designed to safely retain such gases and work well during transit because they can operate at high and low pressures.
BS EN 13371 guideline provides manufacturers with the terminology, requirements, and test methods for the quality assurance of valves for cryogenic service. To keep cryogenic gases or other mediums secure and safe, cryogenic couplings are kept in a naturally closed condition. BS EN 13371 provides manufacturers with test methods for increased efficiency, durability, and quality management.
