(I) Mapaipi achitsulo chopanda msoko cha kaboni
| muyezo | Khodi Yokhazikika | Giredi | Kugwiritsa ntchito | Mayeso |
| GB/T8163 | Chitoliro chachitsulo chopanda msoko chonyamulira madzi | 10, 20, Q345 | Mafuta, gasi ndi malo owonetsera anthu onse okhala ndi kutentha kwa kapangidwe kochepera 350℃ ndi kupanikizika kochepera 10MPa | |
| GB3087 | Machubu achitsulo opanda msoko a ma boiler otsika ndi apakati | 10, 20 etc. | Nthunzi yotentha kwambiri ndi madzi otentha ochokera ku ma boiler otsika ndi apakati, ndi zina zotero. | |
| GB9948 | Chitoliro chachitsulo chopanda msoko chakusweka kwa mafuta | 10, 20 etc. | Sikoyenera kugwiritsa ntchito mapaipi achitsulo a GB/T8163. | Kufutukuka, zotsatira |
| GB5310 | Chubu chachitsulo chopanda msoko cha boiler yothamanga kwambiri | 20G ndi zina zotero. | Chotenthetsera nthunzi chotentha kwambiri cha ma boilers opanikizika kwambiri | Kufutukuka, zotsatira |
| GB6479 | Chitoliro chachitsulo chosasunthika champhamvu chazida za feteleza | 10, 20G, 16Mn etc. | Mafuta ndi gasi okhala ndi kutentha kwa kapangidwe kake kwa -40 ～400℃ ndi kuthamanga kwa kapangidwe kake kwa 10.0 ～32.0MPa | Kukula, kukhudza, kulimba kwa kutentha kochepa |
| GB/T9711 | Mikhalidwe yoperekera mapaipi achitsulo ku mafakitale amafuta ndi gasi |
Kuwunika: Kawirikawiri, mapaipi achitsulo oyendera madzi ayenera kuyesedwa ndi mankhwala, kuyesedwa kwa mphamvu, kuyesedwa kwa kupendekera ndi kuyesedwa kwa kuthamanga kwa madzi. Kuwonjezera pa mayeso omwe ayenera kuchitidwa pa mapaipi achitsulo oyendera madzi, mapaipi achitsulo a GB5310, GB6479 ndi GB9948 amafunikanso kuti ayesedwe kukula ndi kuyesedwa kwa mphamvu; zofunikira zowunikira kupanga mapaipi atatu achitsulo awa ndi zokhwima kwambiri. Muyezo wa GB6479 umaperekanso zofunikira zapadera pakulimba kwa mphamvu ya zinthu kutentha kochepa. Kuphatikiza pa zofunikira zonse zoyesera mapaipi achitsulo oyendera madzi, mapaipi achitsulo a muyezo wa GB3087 amafunikanso kuti ayesedwe kozizira. Kuphatikiza pa zofunikira zonse zoyesera mapaipi achitsulo oyendera madzi, mapaipi achitsulo a muyezo wa GB/T8163 amafunika kuti ayesedwe kukula ndi kuyesedwa kozizira malinga ndi mgwirizano. Zofunikira zopangira mapaipi awiriwa sizokhwima ngati zitatu zoyambirira. Kupanga: Mapaipi achitsulo a miyezo ya GB/T/8163 ndi GB3087 nthawi zambiri amasungunuka ndi ng'anjo yotseguka kapena chosinthira, ndipo zigawo zawo zodetsedwa ndi zolakwika zamkati ndizochulukirapo. GB9948 imasungunuka kwambiri ndi ng'anjo yamagetsi. Ambiri mwa iwo awonjezera njira yoyeretsera kunja kwa ng'anjo, ndipo kapangidwe kake ndi zolakwika zamkati ndizochepa. Miyezo ya GB6479 ndi GB5310 imafotokoza zofunikira pakuyeretsera kunja kwa ng'anjo, ndi zinthu zosadetsedwa kwambiri komanso zolakwika zamkati, komanso mtundu wapamwamba kwambiri wa zinthu. Miyezo yaubwino wopanga wa miyezo yapaipi yachitsulo yomwe ili pamwambapa ili mu dongosolo kuyambira pansi mpaka pamwamba: GB/T8163
(II) Mapaipi achitsulo chopanda zitsulo zotayidwa Mu zida zopangira petrochemical, miyezo ya mapaipi achitsulo chopanda zitsulo zotayidwa omwe amagwiritsidwa ntchito kwambiri ndi GB9948 "Mapaipi achitsulo chopanda zitsulo zotayidwa kuti aswe mafuta" GB6479 "Mapaipi achitsulo chopanda zitsulo zotayidwa kuti azigwiritsidwa ntchito popanga feteleza" GB/T5310 "Mapaipi achitsulo chopanda zitsulo zotayidwa kuti azigwiritsidwa ntchito popanga boilers othamanga kwambiri" GB9948 ili ndi magiredi azinthu zachitsulo za chromium-molybdenum: 12CrMo, 15CrMo, 1Cr2Mo, 1Cr5Mo, etc. GB6479 ili ndi magiredi azinthu zachitsulo za chromium-molybdenum: 12CrMo, 15CrMo, 1Cr5Mo, etc. GB/T5310 ili ndi magiredi azinthu zachitsulo za chromium-molybdenum ndi magiredi azinthu zachitsulo za chromium-molybdenum: 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12Cr1MoVG, ndi zina zotero. Pakati pawo, GB9948 imagwiritsidwa ntchito kwambiri, ndipo mikhalidwe yosankha ndi iyi pamwambapa.
