Izici zikaMechanical:
•I-Duplex Stainless Steels cishe inamandla esivuno aphindwe kabili kozakwabo wamabanga ama-austenitic.
•Lokhu kuvumela abaklami bemishini ukuthi basebenzise i-thinner gauge material ekwakheni umkhumbi!

Inzuzo ye-Duplex yensimbi engagqwali:
1. Uma kuqhathaniswa nensimbi engagqwali ye-austenitic
1) Amandla okukhiqiza aphakeme ngokuphindwe kabili kunalawo ensimbi engagqwali ye-austenitic ejwayelekile, futhi inokuqina kwepulasitiki okwanele okudingekayo ekubunjweni. Ugqinsi lwethangi noma umkhumbi wokucindezela owenziwe ngensimbi engagqwali eyi-duplex luphansi ngo-30-50% kunalolo lwensimbi engenasici ye-austenitic evame ukusetshenziswa, okuzuzisa ukunciphisa izindleko.
I-2) Inokumelana okuhle kakhulu nokucindezeleka kokuqhekeka kokugqwala, ikakhulukazi endaweni equkethe ama-ion e-chloride, ngisho ne-duplex alloy enokuqukethwe kwe-alloy ephansi inokumelana okuphezulu nokucindezeleka kokuqhekeka kokugqwala kune-austenitic stainless steel. I-Stress corrosion Inkinga evelele okunzima ukuyixazulula evamile ye-austenitic stainless steel.
3) Insimbi engagqwali engu-2205 esetshenziswa kakhulu emithonjeni eminingi yezindaba inokumelana nokugqwala okungcono kunensimbi engagqwali engu-316L evamile, kuyilapho i-super duplex insimbi engagqwali inokumelana nokugqwala okuphezulu. Kwezinye imidiya, njenge-acetic acid ne-formic acid. Ingakwazi ngisho nokuthatha indawo yezinsimbi ezingagqwali ze-alloy austenitic kanye nama-alloys amelana nokugqwala.
4) Inokumelana okuhle nokugqwala kwendawo. Uma iqhathaniswa nensimbi engagqwali ye-austenitic enokuqukethwe kwe-alloy efanayo, inokumelana kangcono nokugqoka kanye nokumelana nokukhathala kokugqwala kune-austenitic stainless steel.
I-5) I-austenitic insimbi engagqwali ine-coefficient ephansi yokunwetshwa komugqa futhi iseduze ne-carbon steel. Ifanele ukuxhunywa ne-carbon steel futhi inokubaluleka okubalulekile kobunjiniyela, njengokukhiqiza amapuleti ayinhlanganisela noma ama-linings.

2. Uma kuqhathaniswa nensimbi engagqwali ye-ferritic, izinzuzo ze-duplex insimbi engagqwali zimi kanje:
1) Izakhiwo zemishini ezibanzi ziphakeme kunalezo zensimbi engagqwali ye-ferritic, ikakhulukazi ukuqina kwepulasitiki. Ayizweli njengokuqina njengensimbi engagqwali ye-ferritic.
2) Ngaphezu kokumelana nokugqwala kwengcindezi, okunye ukumelana nokugqwala kwendawo kuphakeme kunensimbi engagqwali ye-ferritic.
3) Ukusebenza kwenqubo ebandayo yokusebenza kanye nokusebenza okubandayo kokwakha kungcono kakhulu kunensimbi engagqwali ye-ferritic.
I-4) Ukusebenza kwe-welding kungcono kakhulu kunokwensimbi engagqwali ye-ferritic. Ngokuvamile, akukho ukwelashwa okushisa okudingekayo ngemva kokushisa kwangaphambili ngaphandle kokushisela.
5) Ibanga lesicelo libanzi kunalelo lensimbi engagqwali ye-ferritic.

IsiceloNgenxa yamandla aphezulu ensimbi eyi-duplex, ijwayele ukonga izinto, njengokunciphisa ukushuba kodonga lwepayipi. Ukusetshenziswa kwe-SAF2205 kanye ne-SAF2507W njengezibonelo. I-SAF2205 ilungele ukusetshenziswa ezindaweni ezine-chlorine futhi ifanele ukusetshenziswa endaweni yokucwenga noma enye inqubo yemidiya exutshwe ne-chloride. I-SAF 2205 ifaneleka ngokukhethekile ukusetshenziswa kuzishintshi zokushisa eziqukethe i-chlorine enamanzi noma amanzi anosawoti njengendawo yokupholisa. I-material ibuye ilungele izixazululo ze-sulfuric acid kanye nama-asidi e-organic ahlanzekile nezingxube zawo. Okufana nalokhu: amapayipi kawoyela embonini kawoyela negesi: ukuchithwa kukawoyela ongahluziwe ezindaweni zokuhluzwa, ukuhlanzwa kwamagesi anesulfure, izinto zokuhlanza amanzi angcolile; amasistimu okupholisa esebenzisa amanzi anosawoti noma izixazululo ezine-chlorine.

Ukuhlola Okubalulekile:
I-SAKY STEEL iqinisekisa ukuthi zonke izinto zethu zokusebenza zidlula ekuhlolweni kwekhwalithi eqinile ngaphambi kokuzithumela kumakhasimende ethu.

• Ukuhlolwa Kwemishini Okufana Nokuqina Kwendawo
• Ukuhlolwa kokuqina
• Ukuhlaziywa Kwamakhemikhali - Ukuhlaziywa Kwe-Spectro
• I-Positive Material Identification – Ukuhlolwa kwe-PMI
• Ukuhlolwa kokucaba
• I-Micro kanye ne-MacroTest
• Ukuhlolwa kokumelana ne-Pitting
• Ukuhlolwa kokuvutha
• Ukuhlolwa kwe-Intergranular Corrosion (IGC).

WAMUKELA UMBUZO.
