Tulaga Autu ole Duplex 2205
Tulaga Fa'apitoa Malosi-i-Mamafa: Vasega 2205 e maua ai le malosi e tusa ma le faaluaina o u'amea austenitic masani. Ole mea lea e mafai ai ona fausia fausaga (va'a, tane, paipa, ma isi) 30-50% manifinifi, fa'aitiitia le mamafa ma tau o meafaitino a'o fa'atumauina tutusa fua fa'atatau o le mamafa po'o le gafatia o uta.
Mata'utia Tete'e a'e: O le maualuga o le chromium, molybdenum, ma le nitrogen mea e maua ai le 2205 stainless steel e sili atu le lelei o le fa'a'ele'ele lautele nai lo le 316L/317L. E tete'e ai le pala ma le ga'o i totonu ole si'osi'omaga e maua ai le chloride e sili atu le lelei nai lo le 300-series grades. I fa'asalalauga fa'asalalau po'o suasami, o le duplex 2205 e masani ona sili atu nai lo austenitics masani; e mafai fo'i ona suitulaga u'amea super duplex mo u'amea nickel taugata i tulaga sili ona faigata.
Fa'amamafa Sili Fa'asagaga Ta'eta'e Tete'e:O le fa'apipi'i fa'ato'aga e tu'uina atu ai le fa'alavelave fa'afuase'i i le ta'e a'e o le chloride stress (SCC). E o'o fo'i i togi la'ititi la'ititi e sili mamao atu i le 304/316 fa'amauina i su'ega SCC. O le mea lea e lelei ai le 2205 mo si'osi'omaga susu, masima, po'o si'osi'omaga (gaogao ole gataifale, fa'amama fa'amama, fa'amalieina o le sami, ma isi) lea e ta'e ai u'amea austenitic i le fa'alavelave.
Malosi maualuga ma le vaivai: O le Duplex 2205 e fa'atumauina le maa'a'a lelei (tusa lava pe i lalo ifo o le vevela o le vevela) ma tetee atu i le tupu a'e i lalo ole uta fa'ata'amilomilo e sili atu le lelei nai lo u'amea austenitic tutusa. E mitiia le tele o le malosi i lalo o le a'afiaga poʻo le vibration, faʻamalosia atili ai i lalo o avega faʻamalosi poʻo faʻalavelave faʻafuaseʻi. O lona ma'a'a maualuga pe a fa'atusatusa i le fa'amauina 304/316 e maua ai fo'i le fa'aleleia atili o le ofuina i tulaga fa'afefe.
Fa'aloloto Fa'amala maualalo ma Feso'ota'i Carbon-Steel:Vasega 2205 o loʻo i ai se faʻatusatusaga maualalo o le faʻalauteleina o le vevela (latalata i le sila carbon). E aoga lea pe a uelo po'o fa'aofuina laminating i carbon steel, talu ai o fua fa'alautele tutusa e fa'aitiitia ai le fa'alavelave ma le fa'alavelave. E fa'atumauina fo'i le tulaga mautu i suiga o le vevela e sili atu nai lo 300-series alloys.

Kemisi ma Fa'agasologa Alamanuia: Lelei mo vaʻa mamafa, tane e teu ai le mamafa, paipa, ma faʻafefe vevela i vailaʻau vailaʻau, gaosiga o le suka, ma fale gaosi petrochemical. Na te taulimaina acids pala, alkalis, ma solvents lea e ono faaletonu ai le 300-series stainless.
Suau'u, Kesi ma Atunu'u: Faʻaaogaina i paipa, risers, separators, ma vaega faʻavae. O lona tetee atu i le chloride stress corrosion ta'e e taua tele mo pamu tui o le sami, paipa vai masima, ma si'osi'omaga o le gataifale i su'esu'ega ma gaosiga i fafo.
Totogi Suavai ma Fa'a'ese'esega: O lo'o fa'afaigaluegaina i faiga e fa'amalie ai le suasami, fale fa'amama fa'amaina, ma vai fa'aleaga. Duplex 2205's pitting resistance e mautinoa ai le umi o le auaunaga i le faʻafesoʻotaʻi ma brines poʻo vai togafitia.
Alamanuia a'oa'o ma Pepa: E fa'aaogaina i mea e fa'amama, olo fa'amalama, ma tane e teu ai vaila'au. E tetee atu i le maualuga o le vevela ma vailaʻau faʻamalosi (pei o le chlorine dioxide ma le ava malosi) e faʻafeiloaʻi i le pulupulu ma le faʻamalama.
Mea'ai, Meainu ma Fa'agaio'iga Fa'afoma'i: E fetaui lelei mo tane, paipa, ma meafaigaluega i le gaosiga o meaʻai, faʻafefeteina, susu, ma vailaʻau. E ofoina atu le malosi ma le fa'a'ele'ele i lalo o le fa'amama mama ma tulaga tumama.
Masini Alamanuia ma Vaega o le Gataifale: Faʻaaogaina i vaega pamu ma valve, impellers, shafts, ma vaega faʻavae e manaʻomia ai le malosi maualuga ma le faʻafefe. Fa'aoga fo'i i fauva'a, fausaga i fafo, ma pusa felauaiga e fa'aalia i tulaga faigata.
Isi fa'aoga fa'ainisinia: Po'o fea lava e mana'omia ai se tu'ufa'atasiga o le malosi maualuga, ma'a'a'a, ma le fa'a'ele'ele. O fa'ata'ita'iga e aofia ai fa'amau, fa'au'u, paipa fa'afesuia'i vevela, ma vaega fa'avae i le fa'atupuina o le eletise, eli, ma le gaosiga lautele.
