Mafotokozedwe a mapaipi achitsulo cha kaboni akuluakulu amatanthauzidwa ndi mainchesi akunja, makulidwe a khoma, kutalika, ndi mtundu wa zinthu. Mainchesi akunja nthawi zambiri amakhala pakati pa 200 mm ndi 3000 mm. Kukula kwakukulu koteroko kumawathandiza kunyamula madzi ambiri ndikupereka chithandizo cha kapangidwe kake, chofunikira kwambiri pamapulojekiti akuluakulu.

Chitoliro chachitsulo chotenthedwa ndi moto chimaonekera bwino chifukwa cha ubwino wake wopanga: kugwedezeka kwa kutentha kwambiri kumasintha ma billets achitsulo kukhala mapaipi okhala ndi makulidwe ofanana a khoma komanso kapangidwe kolimba ka mkati. Kulekerera kwake kwa dayamita yakunja kumatha kulamulidwa mkati mwa ± 0.5%, zomwe zimapangitsa kuti chikhale choyenera mapulojekiti omwe ali ndi zofunikira zolimba, monga mapaipi a nthunzi m'malo opangira magetsi akuluakulu komanso maukonde otenthetsera apakati m'mizinda.

Chitoliro chachitsulo cha kaboni cha Q235ndiChitoliro chachitsulo cha kaboni cha A36khalani ndi malire omveka bwino a zinthu zosiyanasiyana.

1.Chitoliro chachitsulo cha Q235Chitoliro chachitsulo cha Q235 ndi chitoliro chachitsulo chodziwika bwino chomwe chimagwiritsidwa ntchito popanga kaboni ku China. Ndi mphamvu yotulutsa ya 235 MPa, nthawi zambiri chimapangidwa ndi makulidwe a makoma a 8-20 mm ndipo chimagwiritsidwa ntchito makamaka poyendetsa madzi otsika mphamvu, monga madzi ndi ngalande za m'matauni, ndi mapaipi a gasi wamba m'mafakitale.

2.Chitoliro chachitsulo cha kaboni cha A36Chitoliro chachitsulo cha kaboni cha A36 ndiye chitsulo chachikulu pamsika wapadziko lonse lapansi. Chili ndi mphamvu yokwera pang'ono yobereka (250MPa) komanso kusinthasintha kwabwino. Mtundu wake waukulu (nthawi zambiri wokhala ndi mainchesi akunja a 500mm kapena kuposerapo) umagwiritsidwa ntchito kwambiri m'mapaipi osonkhanitsa ndi kunyamula mafuta ndi gasi, omwe amafunika kupirira kusinthasintha kwa kuthamanga ndi kutentha.
