Chitsulo chosapanga dzimbiri cha paipicholetsa motoNdi chida chofunikira kwambiri chotetezera mapaipi otumizira mafuta ndi mpweya. Chopangidwa ndi chitsulo chosapanga dzimbiri 316, chimakwirira kukula kuyambira DN50 mpaka DN300. Chopereka chathu chachikulu ndi chotchingira moto cha DN200, chomwe chimapereka chitetezo chodalirika cha moto ndi kuphulika kwa makina otumizira madzi m'mikhalidwe yovuta yogwira ntchito.

Mapaipi a mafakitale nthawi zambiri amanyamula mpweya wophulika woyaka ndi nthunzi ya mafuta yosakhazikika. Kulowa kwa moto m'mapaipi kungayambitse ngozi zamoto ndi kuphulika. Zinthu zoletsa moto za carbon steel zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala pachiwopsezo cha dzimbiri pansi pa zinthu zowononga, zomwe zimafupikitsa nthawi yogwira ntchito komanso kumabweretsa zoopsa zazikulu. Ichi ndichifukwa chake mapulojekiti ambiri amasankha zinthu zoletsa moto zachitsulo chosapanga dzimbiri 316.

Mndandanda wa zomangira moto uwu uli ndi zinthu zabwino kwambiri. Thupi lake lalikulu ndi lopangidwa ndi chitsulo chosapanga dzimbiri 316 chokhala ndi asidi wabwino komanso cholimba, choyenera kugwiritsidwa ntchito ndi mpweya wowononga komanso mankhwala onyowa. Choyikapo moto chozimitsa moto cholimba bwino chimatha kuzimitsa moto mwachangu ndikuletsa kufalikira kwa flashback, pomwe chimasunga kuyenda bwino kwapakati ndi kutsika pang'ono kwa mphamvu. Kapangidwe ka flange kolumikizidwa ndi bolt kogawanika kamalola kusweka mosavuta. Chinthu chomangira moto chimatha kuchotsedwa kuti chiyeretsedwe ndikukonzedwa kuti muchepetse ndalama zogwirira ntchito. Kulumikizana kwa flange wamba kumathandiza kukhazikitsa kosavuta pamalopo komanso kugwirizana ndi miyezo yayikulu ya mapaipi amafakitale.

Zimabweretsa ubwino waukulu pakugwiritsa ntchito. Kugwira ntchito kodalirika kosaphulika kumaletsa kubwerera kwa mapaipi ndikuletsa kuphulika kwa moto. Kukana dzimbiri bwino kumathandiza kugwira ntchito kwa nthawi yayitali m'madzi a m'nyanja, mpweya wotayidwa ndi mankhwala ndi mpweya wowononga mafuta popanda dzimbiri kapena kubowoka. Pali mitundu ingapo ya DN50-DN300. Mtundu wa DN200 womwe wagwiritsidwa ntchito kwambiri umagwirizana ndi mapaipi ambiri apakatikati. Kapangidwe kake kolimba kamapereka kukana kwakukulu komanso nthawi yayitali yogwirira ntchito, kuchepetsa kuchuluka kwa kusintha ndikusunga ndalama zomwe makasitomala amawononga komanso nthawi yopuma yopangira.

Amagwiritsidwa ntchito kwambiri poyendetsa mafuta, kuyeretsa mafuta, kukonza mpweya wotayira mankhwala, mapaipi otulutsa mpweya m'matangi, makampani opanga mankhwala a malasha ndi madera ena amafakitale. Monga gawo lofunikira la chitetezo pamapaipi, limamanga chitsimikizo cholimba chachitetezo pa ntchito yonse yopanga.
