Discussion on Application of Hydrogen Compatibility Test on Hydrogen Transmission Steel Pipe

Starting from the concept, the purpose, and the applicable standards associated with the hydrogen compatibility test on the hydrogen transmission steel pipe, separate descriptions of the said test are made here in the article, involving the sampling regulations, the test parameters, the presentation of the test result, the test items, the test duration and quality control direction as well as items needing attention such as assurance of the test device performance, the requirements for dimensional processing accuracy of the specimen, and determination of the statistics method, etc. Accordingly suggestions are proposed addressing such aspects as test quality control by the related party, the problem of rather long test duration which might delay the delivery date, and parameters as needs to be described in the applicable standard for the hydrogen compatibility test, and evaluation index information, being helpful for application of the said test, correct evaluation of the hydrogen-transmission pipe quality, and ensuring the safe running thereof, etc.
