1. Mapaipi achitsulo osasunthika amakulungidwa kuchokera kuchitsulo chopangidwa ndi mpweya wamba, chitsulo chochepa cha aloyi kapena chitsulo chopangidwa ndi aloyi molingana ndi zinthuzo. Mwachitsanzo, mapaipi opanda mpweya opangidwa ndi chitsulo chochepa cha carbon monga No. 10 ndi No. chitsulo chapakati cha kaboni monga 45 ndi 40Cr Mapaipi opanda msoko omwe amapangidwa amagwiritsidwa ntchito makamaka popanga zida zosiyanasiyana zamakina ndi zopangira mapaipi.

2. Mipope yachitsulo yosasunthika pazinthu zambiri imaperekedwanso molingana ndi kapangidwe ka mankhwala ndi makina, komanso malinga ndi mayeso a hydraulic. Mapaipi achitsulo osasunthika omwe amakhala ndi kuthamanga kwamadzimadzi ayenera kudutsa mayeso a hydraulic pressure.

3. Mapaipi opanda msoko amagwiritsidwa ntchito mu boilers, kufufuza kwa nthaka, mayendedwe, kukana kwa asidi, ndi zina zotero monga petroleum geological pobowola chitoliro.API 5CTJ55, K55, N80, L80, P110, Etc, mapaipi osweka ndi mapaipi owiritsa amakampani a petrochemical.

Mipope yachitsulo yopanda msokoamagwiritsidwa ntchito makamaka pazomangamanga ndi makina. Zida zake zoimira (makalasi): carbon steel No. 20, No. 45 zitsulo; aloyi zitsulo Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, etc.

Mipope yachitsulo yosasunthika yotengera madzimadzi imagwiritsidwa ntchito makamaka potengera mapaipi amadzimadzi muukadaulo ndi zida zazikulu. Zoyimira (makalasi) ndi 20, Q345, etc.

Mipope yachitsulo yopanda msoko yotsika komanso yapakatikatiboilersamagwiritsidwa ntchito makamaka pamapaipi onyamula madzi otsika komanso apakati pama boilers a mafakitale ndi ma boilers apanyumba. Zida zoyimira ndi 10 ndi 20 zitsulo.

Mipope yachitsulo yopanda msokoma boilers apamwambaamagwiritsidwa ntchito makamaka pakutentha kwambiri komanso zotengera zamadzimadzi zotengera mitu ndi mapaipi m'mafakitale amagetsi ndi ma boiler opangira magetsi a nyukiliya. Zoyimira ndi 20G, 12Cr1MoVG, 15CrMoG, etc.

Mipope yachitsulo yopanda msokohigh-pressure feterezazida zimagwiritsidwa ntchito makamaka kunyamula mapaipi otentha kwambiri komanso othamanga kwambiri pazida za feteleza. Zoyimira ndi 20, 16Mn,12CrMo, 12Cr2Mo, etc.

Mapaipi osasunthika achitsulo osweka mafuta amagwiritsidwa ntchito makamaka mu ma boiler, osinthanitsa kutentha ndi mapaipi onyamula madzimadzi muzomera zosungunulira mafuta. Zida zake zoyimira ndi 15mog, 15CrMoG, 12crmog, etc.

Mapaipi achitsulo osasunthika a masilinda a gasi amagwiritsidwa ntchito makamaka kupanga masilindala osiyanasiyana a gasi ndi ma hydraulic. Zoyimira zake ndi 37Mn, 34Mn2V, 35CrMo, etc.

Mapaipi achitsulo osasunthika otentha amagwiritsidwa ntchito popangira ma hydraulic props, omwe amagwiritsidwa ntchito makamaka 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.

Mapaipi achitsulo oziziritsidwa kapena ozizira osasunthika amagwiritsidwa ntchito makamaka pamakina opangira makina ndi zida zosindikizira mpweya, zomwe zimafuna kulondola kwambiri komanso kutsirizika kwabwino pamtunda. Zoyimira zake zikuphatikizapo 20, 45 zitsulo, etc.

Mapaipi achitsulo osakanizika oziziritsa kuzizira ndi mapaipi achitsulo okhala ndi mawonekedwe apadera amagwiritsidwa ntchito makamaka popanga magawo ndi magawo osiyanasiyana. Amapangidwa ndi chitsulo chapamwamba kwambiri cha carbon structural steel ndi chitsulo chochepa cha alloy structural steel.

Mapaipi achitsulo osakanizika amkati mwamapaipi a hydraulic ndi pneumatic cylinders amagwiritsidwa ntchito makamaka popanga mapaipi azitsulo ozizira kapena ozizira okhala ndi mainchesi olondola amkati a ma silinda a hydraulic ndi pneumatic. Zoyimira zake ndi 20, 45 zitsulo, etc.
