Su'esu'ega: su'esu'ega o vaila'au, su'ega fa'alavelave, su'ega fa'amafola ma su'ega o le vai e tatau ona faia i luga o le paipa u'amea fa'aaogaina mo felauaiga lautele o le suavai.

GB5310, GB6479, GB9948e tolu ituaiga o paipa u'amea masani, e faaopoopo atu i le paipa felauaiga vai e tatau ona tofotofoina, ae manaomia foi le faia o le suʻega afi ma suʻega aafiaga; Ole mana'omia ole su'esu'ega o nei ituaiga e tolu o paipa u'amea e matua fa'amalo.

GB6479e fa'apena fo'i e tulaga fa'apitoa mana'oga mo le maualalo o le vevela a'afiaga faigata o meafaitino.

GB3087 paipa u'amea masani, fa'aopoopo i le su'esu'ega lautele mana'omia mo paipa u'amea felauaiga vai, ae mana'omia fo'i le su'ega malulu malulu.

GB / T8163 paipa u'amea masani, i le faaopoopo atu i le suega masani manaomia mo le suavai felauaiga paipa uʻamea, e tusa ai ma manaoga o le maliega e faia le suʻega afi ma suʻega malulu punou. e pei o ituaiga muamua e tolu.

Gaosiga: GB / T / 8163 ma GB3087 paipa uamea tulaga faatonuina o le ogaumu tatala po o le converter smelting, o ona eleelea ma faaletonu totonu e fai si sili atu.

GB9948fa'afefeteina o le ogaumu eletise. O le tele o lo'o fa'aopoopoina i le fa'amamāina o le ogaumu fa'atasi ai ma ni nai mea fa'apitoa ma fa'aletonu i totonu.

GB6479maGB5310faʻataʻitaʻiga latou lava faʻamaʻoti manaʻoga mo le faʻamamaina i fafo atu o le ogaumu, faʻatasi ai ma le maualalo o le eleelea ma faʻaletonu i totonu ma le tulaga sili ona maualuga.

O loʻo i luga le tele o paipa uʻamea o loʻo gaosia i le faasologa o le lelei mai le maualalo i le maualuga:

GB/T8163＜GB3087＜GB9948＜GB5310＜GB6479

Filifiliga: i lalo o tulaga masani, GB / T8163 paipa uamea masani e talafeagai mo le vevela mamanu e itiiti ifo i le 350 ℃, mamafa e itiiti ifo i le 10.0mpa suauu oloa, suauu ma kesi ma tulaga lautele lautele;

Mo oloa suauu, suauu ma kesi ala, pe a sili atu le vevela mamanu nai lo le 350 ℃ poʻo le mamafa e sili atu nai lo le 10.0mpa, e talafeagai le filifiliaGB9948 or GB6479paipa uamea masani;

GB9948 or GB6479e tatau fo'i ona fa'aoga tulaga mo paipa o lo'o fa'agaoioi i tafatafa o le hydrogen po'o totonu o si'osi'omaga e faigofie ona pala.

Ole vevela maualalo lautele (itiiti ifo i le -20 ℃) ​​faʻaaogaina paipa uamea e tatau ona faʻaogainaGB6479tulaga masani, naʻo le faʻamaoti mai o manaʻoga o le maualalo o le vevela o aʻafiaga faigata o mea.

GB3087 maGB5310faʻapitoa faʻatulagaina tulaga faʻapitoa mo tulaga faʻapipiʻi paipa uʻamea. "Tulafono o le vaavaaiga o le saogalemu o le boiler" na faamamafaina ai o mea uma e fesoʻotaʻi ma paipa faʻapipiʻi e aʻafia i le lautele o le vaavaaiga, o le faʻaaogaina o meafaitino ma tulaga masani e tatau ona tausisia tulafono o le saogalemu o le pusa, o le mea lea, faʻafu, nofoaga eletise, faʻamafanafana ma le gaosiga o suauu. masini e faʻaaogaina i paipa ausa lautele e tatau ona faʻaaogaina (e ala i le tuʻuina atu) GB3087 poʻo tulaga masaniGB5310.

E taua le matauina o le tulaga lelei o tulaga lelei paipa paipa, tau paipa uamea e fai si maualuga, e pei oGB9948nai lo GB8163 tau meafaitino e toetoe lava 1/5, o le mea lea, i le filifilia o tulaga o mea paipa uamea, e tatau ona mafaufau e tusa ai ma tulaga o le faaaogaina, uma faatuatuaina ma le tamaoaiga. E tatau foi ona maitauina o paipa uʻamea e tusa ai ma GB / T20801 ma TSGD0001, GB3087 ma GB8163 e le tatau ona faʻaaogaina i le GC1 paipa (sei vagana ai le ultrasonic taʻitasi, le lelei e le itiiti ifo i le L2.5, e mafai ona faʻaaogaina i le GC1 (1) mamanu paipa. mamafa e le sili atu i le 4.0Mpa).
