Chitoliro chachitsulo chosasunthika ndi mtundu wa chitoliro chopanda chitsulo, ndipo ntchito yake ndi yokwera kwambiri kuposa chitoliro chachitsulo chosasunthika, chifukwa chitoliro chachitsulo ichi chili ndi Cr, ndi kukana kwake kutentha, kutsika kwa kutentha ndi kukana kwa dzimbiri kuli bwino kuposa mapaipi ena opanda msoko. Zosayerekezeka, kotero machubu aloyi amagwiritsidwa ntchito kwambiri mumafuta, mankhwala, magetsi, boiler ndi mafakitale ena. Chubu chachitsulo chosasunthika (Seamless Steel Tube) chili ndi gawo lopanda kanthu, chingwe chachitali chachitsulo chosalumikizana mozungulira. Chitoliro chachitsulo chimakhala ndi gawo lopanda kanthu ndipo chimagwiritsidwa ntchito kwambiri ngati payipi yonyamula madzi, monga mapaipi onyamula mafuta, gasi, gasi, madzi ndi zinthu zina zolimba. Poyerekeza ndi zitsulo zolimba monga zitsulo zozungulira, chitoliro chopanda phokoso cha aloyi chimakhala ndi mphamvu yofanana ndi yozungulira komanso yopepuka komanso yopepuka. Ndi gawo lazachuma chitsulo ndipo chimagwiritsidwa ntchito kwambiri popanga zida zamakina ndi zida zamakina, monga kunyamula mafuta. Kupanga mbali mphete ndi aloyi msokonezo zitsulo chitoliro akhoza kusintha mlingo magwiritsidwe zipangizo, kuphweka ndondomeko kupanga, kupulumutsa zipangizo ndi processing nthawi, monga anagubuduza mphete kubala, akanema Jack, etc., amene akhala ankagwiritsa ntchito popanga zitsulo chitoliro. Chitoliro chachitsulo chosasunthika ndi chinthu chofunikira kwambiri pazida zosiyanasiyana wamba, ndipo mbiya, mbiya, ndi zina zotere ziyenera kupangidwa ndi chitoliro chachitsulo. Kuonjezera apo, pamene gawo la mphete likukhudzidwa ndi kupanikizika kwa ma radial mkati kapena kunja, mphamvuyo imakhala yofanana. Chifukwa chake, mapaipi ambiri a aloyi opanda chitsulo ndi mapaipi ozungulira.
Gulu:
Chitoliro chachitsulo chosasunthika: makamaka amagwiritsidwa ntchito popanga zonse komanso makina. Zoyimira zake (mtundu): zitsulo za carbon 20, 45 zitsulo; aloyi zitsulo Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, etc.
Mipope yachitsulo yopanda msoko yotumizira madzi: Amagwiritsidwa ntchito makamaka potengera mapaipi amadzimadzi mu engineering ndi zida zazikulu. Zoyimira (kalasi) ndi 20, Q345, etc.
Mipope yachitsulo yopanda msoko kwa ma boilers otsika komanso apakatikati: Amagwiritsidwa ntchito kwambiri pamapaipi operekera madzi otsika komanso apakatikati pama boiler a mafakitale ndi ma boilers apanyumba. Zoyimira ndi 10, 20 zitsulo.
Mipope yachitsulo yopanda msoko yama boilers othamanga kwambiri: Amagwiritsidwa ntchito kwambiri pakutentha kwambiri komanso kuthamanga kwambiri kunyamula mitu yamadzimadzi ndi mapaipi pama boiler m'mafakitale amagetsi ndi magetsi a nyukiliya. Zida zoyimira ndi 20G, 12Cr1MoVG, 15CrMoG, etc.
Mipope yachitsulo yopanda msoko ya zida za feteleza zapamwamba kwambiri: Amagwiritsidwa ntchito makamaka pakutentha kwambiri komanso mapaipi amadzimadzi othamanga kwambiri pazida za feteleza. Zida zoyimira ndi 20, 16Mn, 12CrMo, 12Cr2Mo, etc.
Mipope yachitsulo yopanda msoko yophwanyira mafuta: Amagwiritsidwa ntchito makamaka mu ma boilers, osinthanitsa kutentha ndi mapaipi awo otumizira madzimadzi muzosungunulira mafuta. Zoyimira zake ndi 20, 12CrMo, 1Cr5Mo, 1Cr19Ni11Nb, etc.
Mipope yachitsulo yopanda waya yamasilinda a gasi: yomwe imagwiritsidwa ntchito kwambiri popanga ma silinda osiyanasiyana a gasi ndi ma hydraulic. Zida zake zoyimira ndi 37Mn, 34Mn2V, 35CrMo ndi zina zotero.
Mapaipi achitsulo osasunthika otentha opangira ma hydraulic props: omwe amagwiritsidwa ntchito kwambiri popanga zothandizira ma hydraulic, masilindala ndi mizati m'migodi ya malasha, komanso masilindala ena a hydraulic ndi mizati. Zoyimira zake ndi 20, 45, 27SiMn, etc.
Chitoliro chozizira chokoka kapena chozizira chopanda chitsulo chosasunthika: chomwe chimagwiritsidwa ntchito kwambiri pamakina, makina osindikizira a kaboni, omwe amafunikira kulondola kwapamwamba komanso kutsirizika kwabwino. Zoyimira zake ndi 20, 45 zitsulo, etc.
