Pazinthu zamakina amafuta ndi gasi, mapaipi achitsulo opanda msoko amagwira ntchito yofunikira.Monga mkulu-mwatsatanetsatane, mkulu-mphamvu zitsulo chitoliro, akhoza kupirira zosiyanasiyana nkhanza chilengedwe monga kuthamanga, kutentha, dzimbiri, etc., choncho chimagwiritsidwa ntchito mapaipi mayendedwe ndi zotengera kuthamanga m'minda mphamvu zatsopano monga mafuta ndi gasi wachilengedwe.
1. Makhalidwe
Mapaipi opanda zitsulo omwe amagwiritsidwa ntchito popanga mafuta ndi gasi ali ndi izi:
1. Zolondola kwambiri: Chitoliro chachitsulo chosasunthika chimakhala ndi khoma lofanana ndi lapamwamba kwambiri, lomwe lingathe kuonetsetsa kuti chitolirocho chikhale chosalala komanso chosindikizidwa.
2. Mphamvu yapamwamba: Popeza mapaipi achitsulo opanda msoko alibe ma welds, ali ndi mphamvu zapamwamba komanso zolimba ndipo amatha kupirira malo ovuta monga kuthamanga kwambiri ndi kutentha kwakukulu.
3. Kukana kwa dzimbiri: Zida za asidi ndi alkali mumafuta ndi gasi zimachititsa kuti mapaipi achitsulo aziwonongeka, koma zinthu zoyambira zomwe zimagwiritsidwa ntchito m'mapaipi opanda zitsulo ndizokwera kwambiri, motero zimakhala ndi mphamvu yolimbana ndi dzimbiri ndipo zimatha kuwonetsetsa kuti payipi ikugwira ntchito bwino.
4. Moyo wautali: Chifukwa cha ndondomeko yokhwima yopangira mapaipi achitsulo osasunthika, moyo wawo wautumiki ukhoza kutsimikiziridwa kuti udzakhalapo kwa zaka zambiri, motero kuchepetsa kuchuluka kwa ndalama zosinthidwa ndi zofanana.
2. Njira yopanga
Njira yopangira mapaipi achitsulo osasunthika amafuta ndi gasi makamaka imaphatikizapo izi:
1. Kusungunula: Onjezerani chitsulo chosungunuka mu ng'anjo kuti musungunuke kuchotsa zonyansa ndi mpweya kuti mutsimikizire chiyero cha chitoliro chachitsulo.
2. Kuponyera kosalekeza: Chitsulo chosungunuka chimatsanuliridwa mu makina opopera mosalekeza kuti amangirire kupanga billet yachitsulo.
3. Kugubuduza: Billet yachitsulo imayendetsedwa ndi njira zambiri zopukutira kuti ziwonongeke ndikupanga mawonekedwe ofunikira a tubular.
4. Kubowola: Chitoliro chachitsulo chokulungidwa chimapangidwa ndi makina obowola kuti apange khoma la chitoliro chachitsulo chosasunthika.
5. Kutentha mankhwala: Kutentha mankhwala ikuchitika pa perforated zitsulo chitoliro kuti athetse nkhawa mkati ndi kusintha mawotchi ake katundu.
6. Kumaliza: Kumaliza kwapamwamba ndi kukonza kwapaipi yazitsulo zosasunthika zotenthedwa ndi kutentha kuti zikwaniritse zosowa za makasitomala.
7. Kuyang'anira: Kuyang'anira mwamphamvu kumachitika pamapaipi omalizidwa opanda zitsulo, kuphatikiza kulondola kwazithunzi, makulidwe a khoma, mawonekedwe amkati ndi kunja, etc., kuonetsetsa kuti zinthu zili bwino.
Mwachidule, mapaipi achitsulo osasunthika omwe amagwiritsidwa ntchito m'munda wamafuta ndi gasi, monga chitoliro chapamwamba kwambiri, champhamvu champhamvu chachitsulo, chimakhala ndi gawo lofunikira pakupatsira mapaipi ndi zotengera zokakamiza m'munda wamagetsi.
Zogulitsa zazikulu zamakampani athu pamakampani amafuta ndi:
