Chitoliro chopanda zitsulo ndi chinthu chofunika kwambiri chachitsulo chomwe chimagwiritsidwa ntchito m'madera ambiri. Kupanga kwake kwapadera kumapangitsa kuti chitoliro chachitsulo chikhale chopanda ma welds, chokhala ndi zida zabwino zamakina komanso kukana kolimba, koyenera malo okhala ndi kuthamanga kwambiri komanso kutentha kwambiri.

Pankhani yogwiritsira ntchito, mapaipi achitsulo osasunthika amagwiritsidwa ntchito m'magawo monga mayendedwe amafuta ndi gasi, makampani opanga mankhwala, zomangamanga, zomanga zombo ndi magalimoto. Makamaka m'makampani amafuta ndi gasi, mapaipi achitsulo osasunthika amagwiritsidwa ntchito popanga mapaipi ndi zida zotsitsa, ndipo amatha kupirira zovuta zachilengedwe.

Ponena za miyezo, mapaipi achitsulo osasunthika nthawi zambiri amapangidwa ndikuyesedwa malinga ndi miyezo ya dziko (monga GB, ASTM, API, etc.).Mtengo wa GB/T8162imagwira ntchito ku mipope yachitsulo yopanda msoko kwa nyumba, pomweChithunzi cha ASTM A106zimagwiritsa ntchito mpweya zitsulo msoko mipope kwa mkulu kutentha utumiki. Kwa mapaipi achitsulo osasunthika a aloyi, miyezo wamba imaphatikizapoChithunzi cha ASTM A335, ndi magiredi oyimira ndi P5 ndi P9 kuti awonetsetse kuti mapaipi achitsulo akugwira ntchito pa kutentha ndi kupanikizika.

Pankhani ya zida, mapaipi azitsulo osasunthika a aloyi nthawi zambiri amagwiritsa ntchito zitsulo zotsika ndi aloyi, zokhala ndi kukana kwa dzimbiri, kukana kutentha kwambiri komanso kukana kwa okosijeni. Mwachitsanzo, zida zomwe zimagwiritsidwa ntchito kwambiri pamapaipi achitsulo a alloy zimaphatikizapo Cr-Mo alloy zitsulo (monga 12Cr1MoG etc.), zomwe zili zoyenera kutentha kwambiri komanso zida zamphamvu kwambiri monga ma boilers ndi osinthanitsa kutentha. Zidazi zimathandizidwa ndi kutentha kwakukulu ndikuwunika kuti zitsimikizire kukhazikika komanso chitetezo chawo pamikhalidwe yovuta kwambiri.

Mipope yachitsulo yopanda msoko, makamaka mapaipi azitsulo opanda aloyi, amagwira ntchito yofunika kwambiri pamakampani amakono. Kupanga kwawo kokhazikika komanso zida zapamwamba zimawapangitsa kukhala chisankho chabwino pamapulogalamu osiyanasiyana aukadaulo.
