GB5310ndi code yokhazikika ya muyezo wa dziko lonse la China wa "Mapaipi Opanda Chitsulo Osemphana aMaboiler Opanikizika Kwambiri", yomwe imafotokoza zofunikira zaukadaulo zamapaipi achitsulo chosasunthika a ma boilers amphamvu komanso mapaipi a nthunzi. Muyezo wa GB5310 umaphimba mitundu yosiyanasiyana ya magiredi achitsulo kuti akwaniritse zosowa zosiyanasiyana zogwiritsira ntchito. Izi ndi zina mwa magiredi wamba ndi mafakitale ogwiritsira ntchito:

20G: 20G ndi imodzi mwa mitundu yomwe imagwiritsidwa ntchito kwambiri mu GB5310, yokhala ndi zigawo zazikulu za kaboni, manganese ndi silicon. Ili ndi mawonekedwe abwino a makina komanso mawonekedwe owotcherera, ndipo imagwiritsidwa ntchito kwambiri popanga zinthu zofunika monga makoma ozizira ndi madzi, ma superheater, ma economizer ndi ma drums m'ma boiler a power station.

15CrMoGChitsulochi chili ndi chromium ndi molybdenum, ndipo chili ndi mphamvu yotentha kwambiri komanso kukana okosijeni. Mapaipi achitsulo opanda msoko a 15CrMoG nthawi zambiri amagwiritsidwa ntchito popanga mapaipi a nthunzi otentha kwambiri komanso amphamvu, ma header ndi ma conduits, ndi zina zotero, ndipo amagwiritsidwa ntchito kwambiri m'mafakitale a petrochemical ndi magetsi.

12Cr1MoVG: Ili ndi zinthu zambiri za chromium, molybdenum ndi vanadium, zomwe zimakhala ndi mphamvu yabwino kwambiri pa kutentha kwambiri komanso zimakhala zokhazikika kwa nthawi yayitali. Mapaipi achitsulo opanda msoko amtunduwu nthawi zambiri amagwiritsidwa ntchito m'maboiler otentha kwambiri komanso amphamvu kwambiri komanso zida zamagetsi za nyukiliya, makamaka zosinthira kutentha, mapaipi a nthunzi, ndi zina zotero.

Mapaipi achitsulo osiyanasiyana osasunthika awa amagwiritsidwa ntchito kwambiri popanga zinthu zofunika kwambiri m'malo otentha kwambiri komanso opanikizika kwambiri monga mphamvu, petrochemical, ndi mphamvu ya nyukiliya chifukwa cha kapangidwe kake ka mankhwala ndi mphamvu zake zapadera. Posankha mtundu woyenera wa chitsulo, chitetezo ndi kukhazikika kwa zidazo pansi pa mikhalidwe yoopsa zitha kutsimikizika, ndipo nthawi yogwirira ntchito imatha kukulitsidwa.
