Discussion on the selection of HG/T 20584 for design, manufacturing and inspection standards [Pressure vessel design data sheet]
Thread Content
When designing pressure vessel drawings, there is a column of "Design, Manufacturing and Inspection Standards" in the "Design Data Sheet". Many drawings only state the provisions of "GB 150/GB/T 151....TSG 21-2016....", while HG/T 20584-2011 1.0.1 states that "This standard is for GB 150 Supplement and Specification of Manufacturing Parts", according to the literal interpretation, the "HG/T 20584-2011" standard should be included in the design data sheet, and Article 5.0.1 of HG/T 20584-2011 points out that the material selection of pressure components should also comply with the provisions of HG/T 20581-2011. In design, it is often encountered that the shell is made of seamless pipes, and Article 5.0.1 of HG/T 20584-2011 points out that the material selection of pressure components should also comply with the provisions of HG/T 20581-2011 "CS should be retested (tensile/impact)." Does the manufacturer have to conduct re-inspection according to this requirement? Can the standard "HG/T 20584-2011" be canceled in the "Design Data Sheet"?
HGT 20581-2011 Re-inspection requirements for seamless steel pipes used as pressure vessel shells HGT 20584-2011 Raw materials used for pressure components should meet the following requirements
* * Standards are the most basic standards, and industry standards are generally stricter than * * standard. Nowadays, most drawings no longer say HG/T20580~20585, and it is not listed as a coordination and reference standard in the regulations.
I mean, can I not follow HG/T 20584 and related standards?
I think the standards required above are proposed by the user design client, and the design is carried out in accordance with the standards required by the users. If HG20584 is mentioned, its relevant requirements must be met.
The specific standard HG/T20584 of GB150 should be written on the data sheet.
