GB13296-2013 (Mapaipi achitsulo chosasunthika a ma boiler ndi ma heat exchanger). Amagwiritsidwa ntchito makamaka mu ma boiler, ma superheater, ma heat exchanger, ma condenser, ma catalytic tubes, ndi zina zotero za makampani opanga mankhwala. Chitoliro chachitsulo chotentha kwambiri, chopanikizika kwambiri, komanso cholimbana ndi dzimbiri. Zipangizo zake zoyimira ndi 0Cr18Ni9, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, ndi zina zotero. GB/T14975-1994 (Chitoliro chachitsulo chosasunthika chachitsulo chosapanga dzimbiri cha kapangidwe kake). Chimagwiritsidwa ntchito makamaka pa kapangidwe kake (kukongoletsa hotelo ndi malo odyera) ndi kapangidwe ka makina amakampani opanga mankhwala, omwe amalimbana ndi dzimbiri la mumlengalenga komanso la asidi ndipo ali ndi mapaipi ena achitsulo amphamvu. Zipangizo zake zoyimira ndi 0-3Cr13, 0Cr18Ni9, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, ndi zina zotero.

GB/T14976-2012 (Chitoliro chachitsulo chosapanga dzimbiri chopanda chitsulo chonyamula madzi). Chimagwiritsidwa ntchito makamaka pa mapaipi omwe amanyamula zinthu zowononga. Zipangizo zoyimira ndi 0Cr13, 0Cr18Ni9, 1Cr18Ni9Ti, 0Cr17Ni12Mo2, 0Cr18Ni12Mo2Ti, ndi zina zotero.

YB/T5035-2010 (Mapaipi achitsulo chosasunthika a manja a ma axle a magalimoto). Amagwiritsidwa ntchito kwambiri popanga mapaipi achitsulo chapamwamba kwambiri cha kaboni ndi alloy structural steel osasinthika achitsulo chotentha cha manja a theka la axle a magalimoto ndi machubu a axle a ma drive axle housings. Zipangizo zake zoyimira ndi 45, 45Mn2, 40Cr, 20CrNi3A, ndi zina zotero.

API SPEC 5L-2018 (chitsanzo cha paipi ya mzere), yosonkhanitsidwa ndi kuperekedwa ndi American Petroleum Institute, imagwiritsidwa ntchito kwambiri padziko lonse lapansi.

Chitoliro cha mzere: chimaphatikizapo mapaipi osapindika komanso olumikizidwa. Mapeto a mapaipi ali ndi malekezero athyathyathya, malekezero olumikizidwa ndi malekezero a soketi; njira zolumikizira ndi kuwotcherera kumapeto, kulumikizana kolumikizira, kulumikizana kwa soketi, ndi zina zotero. Zipangizo zazikulu ndi GR.B, X42, X52. X56, X65, X70 ndi mitundu ina yachitsulo.

API SPEC5CT-2012 (Casing and Tubing Specification) yapangidwa ndi kutulutsidwa ndi American Petroleum Institute (American Petreleum Instiute, yotchedwa "API") ndipo imagwiritsidwa ntchito m'madera onse a dziko lapansi.

Chitoliro: Chitoliro chomwe chimatuluka pansi kupita ku chitsime ndipo chimagwira ntchito ngati khoma la chitsime. Mapaipi amalumikizidwa ndi zolumikizira. Zipangizo zazikulu ndi zitsulo monga J55, N80, ndi P110, ndi zitsulo monga C90 ndi T95 zomwe sizimakhudzidwa ndi dzimbiri la hydrogen sulfide. Chitoliro chake chochepa chachitsulo (J55, N80) chimatha kulumikizidwa ndi chitoliro chachitsulo.

Kupaka Machubu: Chitoliro cholowetsedwa mu chidebe kuchokera pamwamba pa nthaka kupita ku gawo la mafuta, ndipo mapaipiwo amalumikizidwa ndi zolumikizira kapena integrally. Ntchito yake ndikulola chipangizo chopompa kuti chinyamule mafuta kuchokera ku gawo la mafuta kupita pansi kudzera mu chubu. Zipangizo zazikulu ndi magiredi achitsulo monga J55, N80, P110, ndi C90, T95 omwe amalimbana ndi dzimbiri la hydrogen sulfide. Chitoliro chake chochepa chachitsulo (J55, N80) chimatha kulumikizidwa ndi chitoliro chachitsulo.
