Amagwiritsidwa ntchito makamaka mu boilers, superheaters, exchangers kutentha, condensers, catalytic machubu, etc. wa makampani mankhwala. Amagwiritsidwa ntchito kutentha kwambiri, kuthamanga kwambiri, chitoliro chachitsulo chosapanga dzimbiri. Zida zake zoimira ndi 0Cr18Ni9, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, etc. GB/T14975-1994 (Chitsulo chosapanga dzimbiri chosapanga dzimbiri chitoliro). Amagwiritsidwa ntchito kwambiri popanga zinthu zonse (zokongoletsa hotelo ndi malo odyera) komanso makina amabizinesi amabizinesi, omwe amalimbana ndi dzimbiri mumlengalenga ndi asidi ndipo amakhala ndi mipope yachitsulo yamphamvu. Zoyimira zake ndi 0-3Cr13, 0Cr18Ni9, 1Cr18Ni9Ti, 0Cr18Ni12Mo2Ti, etc.

YB/T5035-2010 (Mapaipi opanda zitsulo opanda manja a manja a nkhwangwa yagalimoto). Amagwiritsidwa ntchito kwambiri popanga chitsulo chapamwamba kwambiri cha carbon structural steel ndi alloy structural zitsulo zotentha-zopiringizika zopanda msokonezo zamapaipi agalimoto a manja a theka-axle ndi machubu a ekisi ya ma drive axle housings. Zoyimira zake ndi 45, 45Mn2, 40Cr, 20CrNi3A, etc.

API SPEC 5L-2018 (mafotokozedwe a mapaipi), yopangidwa ndi kuperekedwa ndi American Petroleum Institute, imagwiritsidwa ntchito kwambiri padziko lonse lapansi.

Chitoliro chamzere: chimaphatikizapo mapaipi opanda msoko ndi owotcherera. Mapeto a chitoliro amakhala ndi malekezero athyathyathya, nsonga za ulusi ndi malekezero azitsulo; njira zolumikizirana ndizowotcherera kumapeto, kulumikizana kolumikizana, kulumikizana kwa socket, etc. Zida zazikulu ndi GR.B, X42, X52. X56, X65, X70 ndi makalasi ena zitsulo.

API SPEC5CT-2012 (Casing and Tubing Specification) idapangidwa ndikuperekedwa ndi American Petroleum Institute (American Petreleum Instiute, yotchedwa "API") ndipo imagwiritsidwa ntchito padziko lonse lapansi.

mu:

Choyikapo: Chitoliro chochokera pansi kupita pachitsime ndipo chimakhala ngati chitsime cha khoma. Mapaipi amalumikizidwa ndi ma couplings. Zida zazikulu ndi magiredi achitsulo monga J55, N80, ndi P110, ndi magiredi achitsulo monga C90 ndi T95 omwe amalimbana ndi hydrogen sulfide corrosion. zitsulo zake otsika kalasi (J55, N80) akhoza welded zitsulo chitoliro.

Tubing: Chitoliro chomwe chimayikidwa m'bokosi kuchokera pansi kupita ku mafuta osanjikiza, ndipo mapaipi amalumikizidwa ndi ma couplings kapena kuphatikiza. Ntchito yake ndikulola kuti makina opopera azitha kunyamula mafuta kuchokera pagawo lamafuta kupita pansi kudzera mu chubu. Zida zazikulu ndi magiredi achitsulo monga J55, N80, P110, ndi C90, T95 omwe amalimbana ndi hydrogen sulfide corrosion. zitsulo zake otsika kalasi (J55, N80) akhoza welded zitsulo chitoliro.
