ISO 20602 discusses requirements for valves for use in low-temperature applications. ISO 20602 specifies requirements of design, manufacture, and test methods for cryogenic check valves to have an excellent quality of leakage stability in very low-temperature environments (−50 °C to −196 °C).
ISO 20602 on cryogenic check valves for marine applications is applicable to:
A check valve is used to secure against undesired return flows in pipelines, as it allows the flow of gases or liquids only in one direction.
ISO 20602 provides design requirements and test guidelines to help cryogenic check valves manufacturers to select proper dimensions and designs for the cryogenic check valves (as per the specification for marine applications).
ISO 20602 covers design requirements for the bonnet, disc, gasket, valve seat, hinges and hinge pins, bolts, and nuts. Additionally, a test of materials based on surface treatment is also provided. Complying with these requirements will be essential to ensure safety while adhering to regulatory protocols, thereby minimizing the risk of product damage.
As a manufacturer of vessels, you use ISO 20602 to understand which check valve is suitable for marine applications. Also, you will be able to demonstrate the reliability of your products and build trust throughout the marine supply chain.
