Pakalipano, mapaipi achitsulo amagwiritsidwa ntchito kwambiri ndipo ali ndi mitundu yambiri.Matenthedwe kukula mpweya zitsulo chitoliro ndi chimodzi mwa izo.Lili ndi ubwino wambiri, koma ndithudi si wopanda kuipa.Zotsatirazi ndi kufotokozera mwatsatanetsatane za ubwino ndi kuipa kwa mapaipi otentha owonjezera zitsulo ndiopanga mpweya zitsulo chitoliro, ndikuyembekeza kukuthandizani kumvetsetsa mankhwalawa.

Ubwino wakukulitsa kutenthacarbon steel pipe:

Ikhoza kuwononga mapangidwe a chitoliro chachitsulo, yeretsani kukula kwa mbewu ya chitoliro chachitsulo chowonjezera kutentha, kuthetsa zolakwika za microstructure, kupanga chitoliro chachitsulo chowonjezera kutentha kuti chikhale chophatikizika ndikusintha makina.Kuwongolera uku kumawonekera makamaka mumayendedwe akugubuduza, kuti chitoliro chachitsulo chowonjezera kutentha sichikhalanso ndi isotropy yofananira, ndi thovu, ming'alu ndi porosity zomwe zimapangidwira pakutsanulira zimathanso kuwotcherera pansi pa ntchito ya kutentha kwambiri komanso kuthamanga kwambiri. .

Kuipa kwakukulitsa kutenthacarbon steel pipe:

1. Kupsinjika kotsalira komwe kumachitika chifukwa cha kuzizira kosiyana.Kupsinjika kotsalira kumatanthawuza kupsinjika kwamkati kwamkati popanda mphamvu yakunja.Kupsinjika kotsalira kotereku kumakhalapo mu mapaipi achitsulo owonjezera kutentha a magawo osiyanasiyana.Nthawi zambiri, kukula kwa gawo la gawo lachitsulo, kumapangitsanso kupanikizika kotsalira.Kupanikizika kotsalira mwachibadwa kumakhala kofanana, koma kumakhalabe ndi zotsatira zofanana pa makhalidwe a zitsulo zomwe zimagwiritsidwa ntchito ndi mphamvu zakunja.Zinthu monga kusinthika, kusasokonezeka, kukana kutopa, ndi zina zotero zingakhale ndi zotsatira zoipa.

2. Pambuyo pakuwonjezedwa kwamafuta, ma inclusions osakhala a zitsulo (makamaka opangidwa ndi sulfides ndi oxides ndi silicates) mu chitoliro chachitsulo chowonjezera kutentha amapanikizidwa kukhala mapepala owonda, zomwe zimapangitsa delamination (interlayer).Delamination idzawononga kwambiri mphamvu ya chitoliro chachitsulo chowonjezera kutentha motsatira makulidwe ake, ndipo weldyo ikachepa, kung'ambika kwa interlaminar kuyenera kuchitika.Kupsyinjika pang'ono chifukwa cha kuwotcherera shrinkage nthawi zambiri kangapo kuchuluka kwa zokolola komanso kukulirapo kuposa kupsinjika pang'ono chifukwa cha katundu.
