Problems with valve pressure testing
Thread Content
Which industries use the valves specified by the standards JB/T 9092—1999 for testing and inspection, and GB13927 for pressure testing? Which foreign standard was referenced in formulating the testing and inspection procedures for valves specified in the JB/T 9092—1999 standard?
Which foreign standard was referenced in formulating the testing and inspection procedures for valves specified in the JB/T 9092—1999 standard? Referenced to the American standard API598
Which industries use the valves specified by the standards JB/T 9092—1999 for testing and inspection, and GB13927 for pressure testing? ---------------------------- For these types of valves --------------------------------
JB/T 9092 is formulated based on valve products used in the petroleum, chemical, and natural gas industries, with a focus on upstream and midstream industrial processes； The adopted standard is API 598. The JB/T 9092 standard has been replaced by GB/T 26480. GB/T 13927 is formulated based on valve products for water, oils, and steam, and is oriented towards downstream industrial processes, end-users, and commercial applications. The adopted standard is ISO 5208; the specific standard to be used shall be determined in accordance with the product standards.
That’s right; JB/T9092 was revoked last year and replaced by GB/T26480-2011
Domestic standards commonly suffer from a series of problems caused by mutual references
