Chitoliro chachitsulo chopanda msoko ndi chinthu chofunika kwambiri chachitsulo chomwe chimagwiritsidwa ntchito kwambiri m'magawo ambiri. Njira yake yapadera yopangira imapangitsa chitoliro chachitsulocho kukhala chopanda ma weld, chokhala ndi mawonekedwe abwino amakina komanso kukana kupsinjika, kukhala choyenera malo okhala ndi kuthamanga kwambiri komanso kutentha kwambiri.

Ponena za momwe zinthu zimagwiritsidwira ntchito, mapaipi achitsulo chosasunthika amagwiritsidwa ntchito kwambiri m'magawo monga mayendedwe amafuta ndi gasi, makampani opanga mankhwala, zomangamanga, zomangamanga ndi mafakitale a magalimoto. Makamaka m'makampani opanga mafuta ndi gasi, mapaipi achitsulo chosasunthika nthawi zambiri amagwiritsidwa ntchito pa mapaipi ndi zida zolowera pansi, ndipo amatha kupirira nyengo zovuta zachilengedwe.

Ponena za miyezo, mapaipi achitsulo osapindika nthawi zambiri amapangidwa ndikuyesedwa mogwirizana ndi miyezo ya dziko (monga GB, ASTM, API, ndi zina).GB/T 8162imagwira ntchito pa mapaipi achitsulo opanda msoko pa nyumba, pomweASTM A106imagwiritsidwa ntchito makamaka pa mapaipi opanda msoko a chitsulo cha kaboni kuti agwiritsidwe ntchito kutentha kwambiri. Pa mapaipi opanda msoko a chitsulo chopanda msoko, miyezo yodziwika bwino imaphatikizapoASTM A335, ndipo magiredi oyimira ndi P5 ndi P9 kuti zitsimikizire kuti mapaipi achitsulo amagwira ntchito bwino pa kutentha ndi kupsinjika kwina.

Ponena za zipangizo, mapaipi achitsulo chosasunthika nthawi zambiri amagwiritsa ntchito zitsulo zotsika mtengo komanso zokhuthala kwambiri, zomwe zimakhala ndi kukana dzimbiri, kukana kutentha kwambiri komanso kukana okosijeni. Mwachitsanzo, zipangizo zomwe zimagwiritsidwa ntchito kwambiri pa mapaipi achitsulo chosungunuka ndi monga chitsulo cha Cr-Mo (monga 12Cr1MoG ndi zina zotero), zomwe zimayenera kugwiritsidwa ntchito pazida zotentha kwambiri komanso zothamanga kwambiri monga ma boiler ndi ma heat exchanger. Zipangizozi zimayesedwa ndi kutenthedwa kwambiri kuti zitsimikizire kuti zili zokhazikika komanso zotetezeka pakakhala zovuta kwambiri.

Mapaipi achitsulo chopanda msoko, makamaka mapaipi achitsulo chopanda msoko, amagwira ntchito yofunika kwambiri m'makampani amakono. Kupanga kwawo kokhazikika komanso zipangizo zapamwamba zimapangitsa kuti akhale chisankho chabwino kwambiri pa ntchito zosiyanasiyana zauinjiniya.
