Regarding pipeline standards
Thread Content
Currently, there is a domestic project that uses an overseas process package, and the client requires the use of imperial pipes. What pipeline standards should be used for purchases within the country? I would be extremely grateful if everyone could help!
Aren’t pipeline standards divided into two grades, A and B? Grade B refers to the imperial system...
You can check this standard HG20592-20635-97 (steel flanges, gaskets, fasteners); I usually use it when preparing plans
The statement on the 2nd floor seems to be incorrect; it is the A series that corresponds to British standard pipes, while the B series represents pipes that meet national standards. It’s as if 1” in the A series equals 33.7, whereas it equals 32 in the B series!
Using the petrochemical standard series (pipes and fittings) SH3405, SH3406, SH3407, SH3408, SH3410, or the chemical industry standards’ Series A pipes and fittings HG20553, HG/T21634, HG/T21635, HG20615~20626, HG20627~20633
According to what’s stated above, there’s no problem with that, but why not use the petrochemical standards?
Different industries in the country use different series of standards; it is necessary to determine whether it is the imperial series or the national standard series! ! ! ! Generally, imported pipes follow British standards, while those produced domestically (according to **standards**) usually adhere to national standards
Its process package comes with a piping data sheet, and the pipe diameters are similar to those specified in HG20553. Thank you all for your help! Thank you all!
