Tikufotokoza mfundo zazikulu pakati pa zinthu ziwirizi (chitsulo chofewa kapena chitsulo chosapanga dzimbiri) pansipa. Chitsulo chosapanga dzimbiri chimakhala cholimba kwambiri m'malo okhala ndi mchere ndipo chingagwiritsidwe ntchito m'makampani ogulitsa chakudya, pomwe chitsulo chofewa chimakhala champhamvu ndipo chingapangitse kuti nyongolotsi ziyambe kugwedezeka kwambiri.

chitsulo chofewa:
Chitsulo chofewa, chomwe chimadziwikanso kuti chitsulo cha kaboni, ndicho chitsulo chofala kwambiri pa ntchito zonse, ndipo ma clamp a mapaipi ndi osiyana. Ndi chimodzi mwa chitsulo chochuluka kwambiri chomwe chimaphimba zinthu zosiyanasiyana zamakanika. Izi zikutanthauza kuti kumvetsetsa ndi kutchula kalasi yoyenera kungathandize kwambiri pakugwira ntchito kwa chinthu chomalizidwa. Mwachitsanzo, kupsinjika ndi zofunikira za mapepala achitsulo omwe amapanga mapanelo a thupi la magalimoto ndizosiyana kwambiri ndi za zipangizo zolumikizira mapaipi. Ndipotu, kufotokozera bwino kwa zinthu zolumikizira mapaipi sikofanana ndi chipolopolo ndi zingwe.

Vuto limodzi la chitsulo chofewa ndilakuti chimakhala ndi kukana dzimbiri kwachilengedwe kochepa kwambiri. Izi zitha kuthetsedwa poika chophimba, chomwe nthawi zambiri chimakhala ndi zinc. Kusiyana kwa njira zophikira ndi miyezo kumatanthauza kuti kukana dzimbiri kungakhale malo amodzi omwe ma clamp a payipi amasiyana kwambiri. Muyezo wa Britain wa ma clamp a payipi umafuna kukana dzimbiri lofiira looneka bwino mu mayeso a 5% a mchere wopanda mchere, ndipo zinthu zambiri za kite zosalembedwa sizikwaniritsa izi.

Chitsulo chosapanga dzimbiri:
Chitsulo chosapanga dzimbiri chimakhala chovuta kwambiri kuposa chitsulo chofewa m'njira zambiri, makamaka pankhani ya ma clamp a mapaipi, chifukwa opanga omwe amawononga ndalama zambiri amagwiritsa ntchito mitundu yosiyanasiyana ya zinthu kuti apereke chinthucho ndalama zochepa zopangira komanso magwiridwe antchito otsika.

Opanga ma hose clamp ambiri amagwiritsa ntchito chitsulo chosapanga dzimbiri cha ferritic m'malo mwa chitsulo chofatsa kapena ngati njira yotsika mtengo m'malo mwa chitsulo chosapanga dzimbiri cha austenitic. Chifukwa cha kukhalapo kwa chromium mu alloy, chitsulo cha ferritic (chomwe chimagwiritsidwa ntchito mu ma W2 ndi W3 grades, mu mndandanda wa ma 400-grade) sichifuna kukonzanso kwina kulikonse kuti chiwongolere kukana dzimbiri. Komabe, kusakhalapo kapena kuchepa kwa nickel mu chitsulochi kumatanthauza kuti makhalidwe ake ndi otsika kwambiri poyerekeza ndi ma austenitic stainless steels.

Zitsulo zosapanga dzimbiri za Austenitic zili ndi mphamvu yolimbana ndi dzimbiri pa mitundu yonse ya dzimbiri, kuphatikizapo ma acid, zimakhala ndi kutentha kwakukulu kogwira ntchito, ndipo sizimagwiritsa ntchito maginito. Kawirikawiri ma grade 304 ndi 316 a zitsulo zosapanga dzimbiri amapezeka; zipangizo zonse ziwiri ndizovomerezeka kugwiritsidwa ntchito m'madzi komanso kuvomerezedwa ndi Lloyd's Register, pomwe ma grade ferritic sangatero. Ma grade awa angagwiritsidwenso ntchito mumakampani azakudya ndi zakumwa, komwe ma acid monga acetic, citric, malic, lactic ndi tartaric acid sangalole kugwiritsa ntchito ma ferritic steels.
