S32205 Meatotino Meatotino
ASTM A240/A240M--01 Duplex u'amea u'amea 2205 u'amea o se u'amea u'amea lua e aofia ai le 22% chromium, 2.5% molybdenum ma 4.5% nickel-nitrogen alloy.E maualuga le malosi, lelei a'afiaga faigata ma lelei lautele ma fa'alotoifale tetee corrosion.O le malosi e maua mai ai le 2205 duplex stainless steel e sili atu nai lo le faaluaina o le austenitic stainless steel masani.O lenei vaega e mafai ai e tagata mamanu ona faʻaitiitia le mamafa pe a mamanuina oloa, ma sili atu le taugofie o lenei uʻamea nai lo le 316 ma le 317L.O lenei u'amea e sili ona talafeagai mo le fa'aoga i le -50°F/+600°F le vevela.Mo faʻaoga i fafo atu o lenei vevela, e mafai foʻi ona mafaufauina lenei uʻamea, ae o loʻo i ai ni tapulaʻa, aemaise lava pe a faʻaogaina i fausaga faʻapipiʻi.
Tulaga lelei o le S32205 Duplex Steel
1. O le malosi e maua ai e sili atu nai lo le faaluaina o le austenitic stainless steel masani, ma o loʻo i ai manaʻoga e manaʻomia.
Lava palasitika.O le mafiafia o le puipui o tane teuina po o ipu mamafa e faia i le duplex uamea uʻamea e 30-50% maualalo nai lo le austenite masani faʻaaogaina, lea e faʻaogaina e faʻaitiitia ai tau.
2.It e sili ona tetee atu i le mamafa corrosion ta'e.E oo lava i le u'amea u'amea duplex fa'atasi ai ma le pito sili ona maualalo o lo'o i totonu o lo'o i ai le maualuga o le tete'e atu i le fa'amamafaina o le pala nai lo le sila austenitic, aemaise lava i le si'osi'omaga o lo'o i ai ion chloride.O le pala o le mamafa o se fa'afitauli iloga lea e faigata ona fo'ia le sila austenitic masani.
3.The corrosion teteʻe o le sili ona faʻaaogaina 2205 duplex uʻamea uʻamea i le tele o ala o faasalalauga e sili atu nai lo le masani 316L austenitic uʻamea uʻamea, ao le super duplex uamea uamea e matuaʻi maualuga tetee corrosion, ma i nisi ala o faasalalauga, e pei o le acetic acid, formic acid E mafai foi ona suitulaga maualuga austenitic u'amea u'amea, ma e oo lava i alloys corrosion.
4. E lelei le fa'apitonu'u fa'apitonu'u.Pe a faatusatusa i austenitic uamea uʻamea ma mea tutusa uʻamea anotusi, o lona ofuina teteʻe corrosion ma vaivai vaivai e sili atu nai lo austenitic uʻamea uʻamea.
5. O le coefficient o le faʻalauteleina laina e maualalo ifo nai lo le austenitic stainless steel, lea e latalata i le uamea carbon.E fetaui lelei mo le faʻafesoʻotaʻi ma le carbon steel ma e iai sona taua faʻainisinia taua, e pei o le gaosiga o papatusi tuʻufaʻatasia poʻo linings.
6. E tusa lava pe i lalo o le mamafa o le avega poʻo le mamafa tulaga, o loʻo i ai le maualuga o le malosi o le absorption nai lo austenitic stainless steel, o loʻo i ai tulaga lelei mo vaega faʻavae e feagai ai ma faʻalavelave faʻafuaseʻi e pei o le faʻalavelave, pa, ma isi, ma e iai le aoga aoga.
S32205 Vaega Fa'aaogā Mea
Vaʻa faʻamalosi, tane faʻapipiʻi maualuga, paipa maualuga, mea faʻafefe vevela (faigaluega gaosi vailaʻau).
1. Suauʻu ma kesi paipa, mea faʻapipiʻi vevela.
2. Faiga faʻaogaina o otaota.
3.Pulp ma pepa alamanuia fa'avasegaina, bleaching laau, teuina ma togafitiga faiga.
4. Rotary shafts, lola lolomi, lau, impellers, ma isi mea i totonu o siosiomaga maualuga-malosi ma corrosion.
5. Pusa uta mo va'a po'o loli
6. Meaʻai gaosi meaʻai
