Kufunika kotsatira malangizo enieni a mapaipi achitsulo cha kaboni m'mafakitale sikunganyalanyazidwe. Malangizo awa amatsimikizira kuti zipangizo zomwe zimagwiritsidwa ntchito popanga ndi kupanga zikukwaniritsa miyezo yofunikira kuti zikhale zotetezeka, zokhalitsa, komanso zogwira ntchito. Pakati pa mitundu yosiyanasiyana ya mapaipi, mapaipi achitsulo cha kaboni chopanda msoko amaonekera kwambiri, makamaka pakugwiritsa ntchito kutentha kwambiri.
Chimodzi mwa zofunikira chimakhudza chitoliro chachitsulo cha kaboni chopanda msoko kuyambira NPS 1 mpaka NPS 48 chokhala ndi makulidwe ofanana ndi makoma motsatira muyezo wa ASME B 36.10M. Chofunika kwambiri pa izi ndi mafakitale omwe amafunikira mapaipi omwe amatha kupirira mikhalidwe yovuta kwambiri, monga mafuta ndi gasi, kupanga magetsi, ndi kukonza mankhwala. Kuthekera kwa mapaipi awa kupirira kutentha kwambiri pamene akusunga umphumphu wa kapangidwe kake ndikofunikira kwambiri pachitetezo ndi magwiridwe antchito a mafakitale.
Chikhalidwe chopanda msokonezo cha izichitoliro chachitsulo cha kaboniimapereka zabwino zingapo. Mosiyana ndi mapaipi olumikizidwa, mapaipi osalumikizana amapangidwa ndi chitsulo chimodzi, kuchotsa chiopsezo cha malo ofooka omwe angachitike pa msoko wolumikizira. Kapangidwe kameneka kamawapangitsa kukhala oyenera kwambiri kupindika, kupalasa ndi ntchito zina zofanana, komanso kuwotcherera. Mapaipi achitsulo cha kaboni chopanda msoko ndi osinthika ndipo angagwiritsidwe ntchito m'njira zosiyanasiyana, kuyambira kusamutsa madzi mpaka kuthandizira kapangidwe ka makina olemera.
Pakati pa makampaniwa pali kampani yomwe ili ku Cangzhou, Hebei Province, yomwe yakhala ikutsogolera makampani kuyambira pomwe idakhazikitsidwa mu 1993. Kampaniyo ili ndi malo okwana 350,000 square meters, ili ndi chuma cha RMB 680 miliyoni ndipo imagwiritsa ntchito antchito aluso pafupifupi 680. Zomangamanga zolimba komanso antchito olimba zimathandiza kampaniyo kupanga mapaipi apamwamba achitsulo cha carbon omwe ali ndi zofunikira zenizeni, kuonetsetsa kuti makasitomala amalandira zinthu zodalirika zomwe zimakwaniritsa zosowa zawo zamafakitale.
Kufunika kwandondomeko ya chitoliro cha chitsulo cha kaboniZimapitirira kutsata malamulo kuti zitsimikizire kuti machitidwe a mafakitale ndi odalirika komanso a nthawi yayitali. Mabizinesi akamaika ndalama pa zipangizo zapamwamba zomwe zikugwirizana ndi zofunikira zomwe zakhazikitsidwa, sizimangoteteza ntchito zokha komanso zimawonjezera phindu lonse. Zofunikira zoyenera zimatha kuchepetsa ndalama zokonzera, kuchepetsa kusokonekera kwa ntchito, komanso kukonza chitetezo cha ogwira ntchito.
Kuphatikiza apo, pamene mafakitale akusintha ndipo mavuto atsopano akubuka, kufunikira kwa zipangizo zamakono kukukulirakulira. Mapaipi achitsulo cha kaboni chopanda kaboni omwe amapangidwa ndi kampani ya ku Cangzhou adapangidwa kuti akwaniritse zosowa izi zomwe zikusintha, kupereka mayankho atsopano komanso odalirika. Potsatira mosamalitsa muyezo wa ASME B 36.10M, kampaniyo ikuwonetsetsa kuti zinthu zake ndizoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikizapo zomwe zimafuna ntchito yotentha kwambiri.
Mwachidule, kufunika kwa ma specification a mapaipi a carbon steel mu ntchito zamafakitale sikunganyalanyazidwe. Ma specification awa satsimikizira ubwino ndi magwiridwe antchito a mapaipiwo, komanso amatenga gawo lofunikira pachitetezo ndi magwiridwe antchito amafakitale. Pokhala ndi maziko olimba opanga zinthu komanso kudzipereka ku khalidwe labwino, kampani yomwe ili ku Cangzhou ipitiliza kutsogolera njira yopereka mapaipi a carbon steel opanda msoko omwe amakwaniritsa zofunikira zamakampani. Pamene makampaniwa akupitiliza kukula ndikusintha, zipangizo zapamwamba zipitiliza kuchita gawo lofunika kwambiri pakuyendetsa zatsopano ndi kupambana.
