Kufunika kotsatira ndondomeko yeniyeni ya chitoliro cha carbon steel mu ntchito zamafakitale sikungathe kupitirira. Izi zikuwonetsetsa kuti zida zomwe zimagwiritsidwa ntchito pomanga ndi kupanga zimakwaniritsa zofunikira pachitetezo, kulimba, komanso magwiridwe antchito. Pakati pa mitundu yosiyanasiyana ya mapaipi, mapaipi achitsulo osasunthika a kaboni amawonekera, makamaka pakugwiritsa ntchito kutentha kwambiri.
Chimodzi mwazinthuzo chimakwirira chitoliro chachitsulo chosasunthika cha kaboni kuchokera ku NPS 1 kupita ku NPS 48 yokhala ndi makulidwe odziŵika bwino malinga ndi muyezo wa ASME B 36.10M. Izi ndizofunikira kwa mafakitale omwe amafunikira mapaipi omwe amatha kupirira zovuta, monga mafuta ndi gasi, kupanga magetsi, ndi kukonza mankhwala. Kukhoza kwa mapaipiwa kupirira kutentha kwakukulu pamene kusunga umphumphu wapangidwe n'kofunika kwambiri pa chitetezo ndi ntchito za mafakitale.
Chikhalidwe chopanda msoko cha izicarbon steel pipeimapereka maubwino angapo. Mosiyana ndi mipope yowotcherera, mapaipi opanda msoko amapangidwa kuchokera kuchitsulo chimodzi chachitsulo, kuchotsa chiopsezo cha mfundo zofooka zomwe zingachitike pa seam weld. Katunduyu amawapangitsa kukhala oyenera kupindika, kuwotcherera ndi kupanga zofanana, komanso kuwotcherera. Mipope yachitsulo yopanda mpweya ya carbon imakhala yosunthika ndipo ingagwiritsidwe ntchito m'njira zosiyanasiyana, kuyambira kusamutsa madzimadzi kupita ku chithandizo chamakina olemera.
Pakatikati pa makampaniwa pali kampani yomwe ili ku Cangzhou, m'chigawo cha Hebei, yomwe yakhala ikuyendetsa makampani kuyambira pomwe idakhazikitsidwa mu 1993. Kampaniyi ili ndi dera la 350,000 square metres, ili ndi chuma chonse cha RMB 680 miliyoni ndipo imalemba antchito aluso pafupifupi 680. Zomangamanga zolimba ndi ogwira ntchito amphamvu zimathandiza kampani kupanga mapaipi apamwamba kwambiri a carbon steel kuti akwaniritse zofunikira, kuonetsetsa kuti makasitomala amalandira zinthu zodalirika zomwe zimakwaniritsa zosowa zawo zamakampani.
Kufunika kwandondomeko ya carbon steel pipezimapitirira kutsata kuonetsetsa kuti moyo wautali ndi wodalirika wa machitidwe a mafakitale. Mabizinesi akamagulitsa zinthu zapamwamba kwambiri zomwe zimakwaniritsa zomwe zakhazikitsidwa, samangoteteza magwiridwe antchito komanso amapangitsa kuti pakhale zokolola zambiri. Mafotokozedwe oyenera amatha kuchepetsa mtengo wokonza, kuchepetsa kusokonezeka kwa ntchito, komanso kupititsa patsogolo chitetezo cha ogwira ntchito.
Kuphatikiza apo, pamene mafakitale akusintha komanso zovuta zatsopano zimatuluka, kufunikira kwa zida zapamwamba kukukulirakulira. Mipope yachitsulo yopanda kaboni yopangidwa ndi kampani ya Cangzhou idapangidwa kuti ikwaniritse zosowa zomwe zikusintha, kupereka mayankho anzeru komanso odalirika. Potsatira mosamalitsa muyezo wa ASME B 36.10M, kampaniyo imawonetsetsa kuti zogulitsa zake ndizoyenera kugwiritsa ntchito zosiyanasiyana, kuphatikiza zomwe zimafunikira ntchito yotentha kwambiri.
Mwachidule, kufunikira kwa mafotokozedwe a chitoliro cha chitsulo cha carbon mu ntchito zamafakitale sikunganyalanyazidwe. Sikuti izi zimangotsimikizira ubwino ndi ntchito ya chitoliro, komanso zimagwira ntchito yofunika kwambiri pa chitetezo ndi ntchito za mafakitale. Ndi maziko amphamvu opanga komanso kudzipereka ku khalidwe, kampani ya Cangzhou idzapitiriza kutsogolera njira yoperekera mapaipi opanda mpweya wa carbon steel omwe amakwaniritsa zofunikira zamakampani. Pamene makampani akupitiriza kukula ndi kusinthika, zipangizo zamakono zidzapitiriza kugwira ntchito yofunika kwambiri poyendetsa luso komanso kupambana.
