O le lelei ma le faʻamaonia e fuafua ai le filifiliga o mea e faʻaogaina mo faiga e pei o mea faʻafefe vevela (PHEs), paipa ma pamu i totonu o le suauʻu ma le kesi.Fa'amatalaga fa'apitoa fa'apitoa e fa'amautinoa ai o aseta e maua ai le fa'aauauina o fa'agaioiga i luga o se fa'asologa umi o le olaga a'o fa'amautinoa le lelei, saogalemu ma le puipuiga o le si'osi'omaga.O le mafuaʻaga lea o le tele o tagata faʻatautaia e aofia ai nickel alloys e pei ole Alloy 625 i a latou faʻamatalaga ma tulaga.
I le taimi nei, e ui i lea, e faʻamalosia e inisinia e faʻatapulaʻa tau o tupe faavae, ma o nickel alloys e taugata ma aʻafia i fesuiaiga o tau.Na faʻaalia lea mea ia Mati 2022 ina ua faaluaina le tau o le nickel i le vaiaso ona o fefaʻatauaʻiga maketi, fai ulutala.E ui o tau maualuga o lona uiga o nickel alloys e taugata le faʻaaogaina, o lenei faʻalavelave e faʻatupu ai luitau tau pulega mo inisinia mamanu ona o suiga faʻafuaseʻi o tau e mafai ona faʻafuaseʻi ona aʻafia ai tupe maua.
O se taunuuga, o le tele o inisinia mamanu ua naunau nei e sui le Alloy 625 i isi mea e ui lava latou te iloa e mafai ona latou faʻalagolago i lona tulaga lelei.O le ki o le fa'ailoaina lea o le u'amea sa'o ma le tulaga talafeagai o le fa'afefeteina o le suasami ma tu'uina atu se u'amea e fetaui ma mea tau masini.
O le tasi mea fa'atatau ole EN 1.4652, fa'aigoa ole Outokumpu's Ultra 654 SMO.O lo'o ta'ua o le sila sili ona fa'a'ele'ele i le lalolagi.
Nickel Alloy 625 e aofia ai le itiiti ifo i le 58% nickel, ae o le Ultra 654 e aofia ai le 22%.E tutusa uma le chromium ma le molybdenum.I le taimi lava e tasi, o le Ultra 654 SMO o loʻo i ai foi se vaega itiiti o le nitrogen, manganese ma le kopa, 625 alloy e aofia ai le niobium ma le titanium, ma o lona tau e sili atu le maualuga nai lo le nickel.
I le taimi lava e tasi, o loʻo faʻatusalia ai se faʻaleleia atili o le 316L stainless steel, lea e masani ona manatu o le amataga mo uʻamea uʻamea maualuga.
I tulaga o le faʻatinoga, o le uʻamea e sili ona lelei le teteʻe atu i le pala, maualuga tele le tetee i pitting ma crevice corrosion, ma le lelei teteʻe i faʻamaʻi taʻei.Ae ui i lea, pe a oʻo mai i faiga vai o le sami, e sili atu le faʻaogaina o le uʻamea uʻamea 625 ona o lona teteʻe lelei i siosiomaga chloride.
O le vai o le sami e matua'i pala ona o lona masima e 18,000-30,000 vaega i le miliona o ion chloride.Chlorides o lo'o i ai se lamatiaga o le pala mo le tele o togi u'amea.Ae ui i lea, o meaola i totonu o le sami e mafai foi ona fausia ni biofilms e mafua ai le faʻaogaina o le eletise ma afaina ai le gaioiga.
Faatasi ai ma le maualalo o le nickel ma le molybdenum, o le Ultra 654 SMO alloy blend e maua ai le tele o tau faʻasaoina i luga o tuʻufaʻatasiga maualuga 625 alloy aʻo tumau pea le tulaga tutusa o le faʻatinoga.E masani ona fa'asaoina le 30-40% o le tau.
E le gata i lea, e ala i le faʻaitiitia o mea o loʻo i totonu o elemene faʻafefiloi taua, uamea faʻafefeteina foi e faʻaitiitia ai le lamatiaga o fesuiaiga i le maketi nickel.O se taunuuga, e mafai e le au gaosi oloa ona sili atu le mautinoa i le saʻo o a latou fuafuaga mamanu ma upusii.
O mea fa'ainisinia o meafaitino o se isi itu taua mo inisinia.O paipa, mea fa'afefe vevela, ma isi faiga e tatau ona tatalia le maualuga o le mamafa, fesuisuiai o le vevela, ma e masani ona tete'e masini po'o le te'i.Ole Ultra 654 SMO o loʻo faʻatulagaina lelei i lenei vaega.E maualuga le malosi e pei o le u'amea 625 ma e sili atu le maualuga nai lo isi u'amea u'amea.
I le taimi lava e tasi, e manaʻomia e le au gaosi mea e mafai ona faʻapipiʻiina ma faʻapipiʻiina e maua ai le gaosiga vave ma e faigofie ona maua i le mea e manaʻomia.
I lenei tulaga, o le u'amea o se filifiliga lelei aua o loʻo tumau lelei le faʻaogaina ma le faʻalauteleina lelei o togi austenitic masani, faʻapena lelei mo le mamanuina o ipu vevela vevela malosi ma mama.
E lelei fo'i le fa'aogaina ma o lo'o avanoa i ituaiga eseese e aofia ai coils ma laupepa e o'o atu i le 1000mm lautele ma le 0.5 i le 3mm po'o le 4 i le 6mm mafiafia.
O le isi tau fa'amanuiaga e fa'apea o le u'amea e maualalo le mamafa nai lo le u'amea 625 (8.0 vs. 8.5 kg/dm3).E ui o lenei eseesega e foliga mai e le taua tele, e faʻaitiitia ai tone i le 6%, lea e mafai ona faʻaolaina oe i le tele o tupe pe a faʻatau faʻatasi mo galuega faʻatino e pei o paipa ogalaau.
I luga o lenei faʻavae, maualalo le mamafa o lona uiga o le fausaga maeʻa o le a mama, faʻafaigofie ona faʻaogaina, sii ma faʻapipiʻi.E aoga tele lenei mea i totonu o le sami ma fafo o loʻo faʻaogaina ai masini mamafa e sili atu ona faigata ona taulimaina.
Tuuina atu uma foliga ma faʻamanuiaga o le Ultra 654 SMO - maualuga le faʻafefeteina ma le malosi faʻainisinia, tau mautu ma le mafai ona fuafua saʻo - e manino lava le mafai ona avea ma sui sili atu le tauvaga i nickel alloys.
