At sasaalloy, sibonelela ngeemveliso zensimbi ezingenasici zekhemikhali ezihlangabezana nemigangatho yamazwe ngamazwe kunye neemfuno ezikhethekileyo zabathengi.

Izinto ekufuneka ziqwalaselwe xa ukhetha iStainless Steel

Xa ukhetha insimbi engenasici kwizicelo zeekhemikhali, iinjineli kufuneka zivavanye:

• Ukubunjwa kweekhemikhali zenkqubo yemidiya

• Ukugxila, ubushushu kunye noxinzelelo

• Uhlobo lomhlwa (umzekelo, ngokubanzi, ukugoba, ukuqhekeka koxinzelelo)

• Iimfuno zokuwelda kunye nokwenziwa

• Ukuthotyelwa ngokusemthethweni kunye nococeko

• Iindleko kunye nokufumaneka

Ukungalingani phakathi kokusingqongileyo kunye nezinto eziphathekayo kunokukhokelelaukusilela kwangaphambi kwexesha, ukuvalwa okuxabisa imali eninzi, kunye neengozi ezinokubakho zokhuseleko.

AmaBanga eNsimbi eStainless aQhelekileyo oLungiso lweMichiza

1. 304 Intsimbi engatyiwa

• Ukuqamba: 18% chromium, 8% nickel

I-304 isetyenziswa ngokubanzi kwizixhobo zemichiza yenjongo ngokubanzi, ngakumbi aphoiiasidi ezithambileyookanye iindawo ezingezizo i-chloride zikhona.

2. 316 / 316L iNtsimbi eNgatyiwayo

• Ukuqamba: 16% chromium, 10% nickel, 2% molybdenum

• Iingenelo: Ukuphucula ukuxhathisa kwiikloridi kunye neendawo ezine-acidic

• Usetyenziso: Iireactors, izitshintshi zobushushu, ii-evaporators, iivalvu

316L unayoumxholo wekhabhoni ephantsi, ukwenza kube ngconoizicelo weldingapho ukubola kumalungu kunokuba yingozi.

3. I-317L yeNtsimbi engatyiwa

• Ukuqamba: I-molybdenum ephezulu kune-316L

• Iingenelo: Ukomelezwa kokuchasai-chloride pitting kunye ne-corrosion ye-crevice

• Usetyenziso: I-Pulp kunye ne-bleaching yephepha, i-reactors chemicals, i-scrubbers

Xa i-316L iwa mfutshane kwiindawo ezinobungozi kakhulu, i-317L inika inyathelo loqoqosho ekukhuseleni.

4. I-904L yeNtsimbi eNgatyiwayo

• Ukuqamba: I-nickel ephezulu kunye nomxholo we-molybdenum

• Iingenelo: Igqwesile ngaphakathiiindawo zeasidi ezomeleleyokuquka i-sulfuric, i-phosphoric, kunye ne-acetic acids

• Usetyenziso: Abatshintshi bobushushu, izixhobo zokukha, ukuveliswa kweasidi

I-904L ixhathisa zombini ukunciphisa kunye ne-oxidizing agents kwaye isebenza ngokukodwa ngokuchaseneamajelo eendaba ndlongokumaqondo obushushu aphezulu.

5. I-Duplex Stainless Steels (umz., 2205, 2507)

• Ukuqamba: Ukulungelelaniswa kwesakhiwo se-austenitic-ferritic

• Iingenelo: Amandla aphezulu, ukumelana kakuhleukuqhekeka kwe-corrosion yoxinzelelo

• Usetyenziso: Iinqanawa zoxinzelelo, abatshintshisi bobushushu, ukusetyenzwa kwe-offshore

I-Duplex stainless steels idibanisa iipropathi ezingcono kakhulu ze-austenitic kunye ne-ferritic steels, ezenza zibe zilungele ukuxinzezeleka okuphezulu, ukusetyenziswa kwe-chloride-rich.

6. I-alloy 20 (UNS N08020)

• Iingenelo: Yenzelwe ngokukodwaukumelana ne-asidi ye-sulfuric

• Usetyenziso: Iitanki zokugcina i-asidi, izixhobo zokukha, ukuthuthwa kweekhemikhali

I-alloy 20 inika ukhuseleko oluhle kakhuluiinkqubo ze-acidic kunye ne-chloride-laden, ehlala idlula i-316 kunye ne-904L kwiindawo zesulfuric.

Izicelo kuShishino lweMichiza

Intsimbi engatyiwayo isetyenziswa phantse kuwo onke amanqanaba okwenziwa kwemichiza, kubandakanywa:

• Izitshintshi zobushushu kunye ne-condensers

• Iinkqubo zombhobho kunye neevalvu

• Iikholamu ze-distillation kunye ne-scrubbers

Ndiyabulela kucoceko kunye nendalo engasebenziyo, insimbi engenasici nayo ifanelekileamayezakwayeimveliso yeekhemikhali zodidi lokutya.

Iinzuzo zokukhetha iBanga eliLungileyo

Ukukhetha umgangatho ochanekileyo wensimbi engenasici kuqinisekisa:
