2205 2507 Austenitic Ferritic Duplex uamea uamea u'amea paipa （Tetee ile chloride corrode）
O le gaosiga o le 2205 ma le 2507 duplex paipa u'amea uamea e masani ona aofia ai laasaga nei:
Sauniuniga o mea mata
Filifili le 2205 poʻo le 2507 pepa poʻo le fasipepa e talafeagai mo ASTM A790 / A789 poʻo le EN 10216-5 faʻataʻitaʻiga.
Fa'ailoga
Fa'agasolo le pepa po'o le fa'asolo i foliga o paipa e ala i le ta'avale malulu po'o le ata malulu.
Uelo
Fa'aaogā le TIG (tungsten pole argon arc welding) po'o le MIG (metal inert gas protective welding). E manaʻomia le faʻatonutonuina o faʻamaufaʻailoga faʻapipiʻi i le taimi o le faʻagasologa o le uelo e faʻamautinoa ai le lelei.
Togafitiga vevela
A maeʻa le faʻapipiʻiina, atonu e manaʻomia togafitiga faʻamaʻi fofo e toe faʻafoʻi ai le faʻafefeteina ma mea faʻainisinia o mea.
Asiasiga ma asiasiga
Faia le suʻega le faʻaleagaina o le paipa uelo, e pei ole suʻesuʻega ultrasonic, suʻesuʻega leitio, ma isi mea, ina ia mautinoa o le uelo e leai ni faaletonu. O su'ega fa'ainisinia ma su'ega fa'asao e faia i le taimi e tasi.
Togafitiga luga
E tusa ai ma le manaʻoga, o le faʻaogaina o le paipa faʻafefeteina, e pei o le pickling, passivation, ma isi, e faʻaleleia atili ai le faʻafefe.
afifiina ma tilivaina
Fa'apipi'i lelei paipa uelo ina ia mautinoa e leai se fa'aleagaina i le taimi o felauaiga.
2205 ma le 2507 lua-vaega uʻamea uamea uʻamea paipa e lelei mo le tele o alamanuia talosaga ona o latou sili chloride corrosion tetee. Pe a filifilia ma faʻaogaina nei mea, faʻamautinoa o loʻo mulimulitaʻia tulaga talafeagai ma faʻamatalaga e faʻamautinoa ai le faʻatinoga ma le saogalemu o mea.
