Su'esu'ega: E masani lava o paipa u'amea mo felauaiga sua e tatau ona faia su'esu'ega o vaila'au, su'ega ta'i, su'ega fa'amafola ma su'ega hydraulic.GB5310, GB6479, ma le GB9948 paipa uʻamea masani, faʻaopoopo i suʻega e tatau ona faia i luga o paipa uʻamea mo le felauaiga o le suavai, suʻesuʻega afi ma suʻega aʻafiaga e manaʻomia foi;o le gaosiga o asiasiga manaʻomia mo nei paipa uʻamea e tolu e matua faʻamalosi.O le tulaga GB6479 e faia ai foi manaoga faapitoa mo le maualalo o le vevela aafiaga faigata o mea.I le faʻaopoopoga i faʻataʻitaʻiga masani o paipa uʻamea mo le felauaiga o le suavai, o paipa uʻamea o le GB3087 e manaʻomia ai foʻi suʻega malulu malulu.GB / T8163 paipa uʻamea tulaga, i le faaopoopo atu i le tulaga manaomia suega lautele mo vai felauaiga paipa uamea, e tusa ai ma le maliega e manaomia ai le suʻega faʻalautele ma suʻega malulu punou.Ole mana'oga o le gaosiga o nei ituaiga paipa e lua e le fa'amaoni e pei o ituaiga muamua e tolu.

Gaosiga: GB / T8163 ma GB3087 paipa u'amea masani e tele lava fa'afefeteina i totonu o le afi tatala po o le liliu, ma o latou le mama ma faaletonu totonu e fai si tele.GB9948 tele lava fa'aaogaina le ogaumu eletise.O le toʻatele oi latou ua auai i le faʻamamaina i fafo atu o le ogaumu, ma o le tuʻufaʻatasiga ma faʻaletonu i totonu e laʻititi lava.O le GB6479 ma le GB5310 faʻataʻitaʻiga latou te faʻatulagaina manaʻoga mo le faʻamamaina i fafo atu o le ogaumu, faʻatasi ai ma le faʻaogaina o le le mama ma faʻaletonu i totonu, ma le tulaga sili ona maualuga.

Filifiliga: I se tulaga lautele, GB / T8163 paipa uʻamea masani e talafeagai mo le suauʻu, suauʻu ma le kesi ma faʻasalalauga lautele ma le vevela mamanu e itiiti ifo i le 350 ° C ma le mamafa o le itiiti ifo i le 10.0MPa;mo le suauu, suauu ma kesi ala o faasalalauga, pe a sili atu le vevela mamanu 350 ° C Pe a sili atu le mamafa nai lo 10.0MPa, GB9948 po GB6479 paipa uʻamea masani;mo paipa o loʻo faʻaogaina i le hydrogen, poʻo paipa o loʻo galue i siosiomaga faʻalavelave faʻaleagaina, GB9948 poʻo GB6479 e tatau foi ona faʻaoga.O paipa uʻamea uma e faʻaaogaina i le maualalo o le vevela (itiiti ifo i le -20 ° C) e tatau ona faʻaaogaina le tulaga GB6479, ma naʻo le faʻamaʻotiina o manaʻoga mo le malosi o le aʻafiaga o le mea.O tulaga GB3087 ma GB5310 o tulaga faʻatulagaina faʻapitoa mo paipa uʻamea.O le "Tulafono o le Vaavaaiga mo le Saogalemu o Boiler" o loʻo faʻamamafaina ai o paipa uma e fesoʻotaʻi atu i le pusa e aofia i le lautele o le vaavaaiga, ma o le faʻaogaina o meafaitino ma tulaga faʻataʻitaʻiga e tatau ona tausisia manaoga o le "Boiler Safety Supervision Regulations".O le mea lea, o loʻo faʻaaogaina i pusa, nofoaga eletise, faʻamafanafana ma fale gaosi oloa.O paipa ausa uma lautele (tuuina atu e le faiga) e tatau ona faʻaaogaina tulaga GB3087 poʻo GB5310.E taua le maitauina o le tau o paipa uʻamea faʻatasi ai ma tulaga lelei paipa paipa lelei e fai si maualuga.Mo se faʻataʻitaʻiga, o le tau o GB9948 e toetoe lava 1/5 maualuga atu nai lo le tau o mea GB8163.O le mea lea, pe a filifilia tulaga faʻameamea paipa uʻamea, e tatau ona tuʻuina atu le iloiloga atoatoa i tulaga o le faʻaaogaina, lea e tatau ona faʻatuatuaina ma Ia taugofie.E tatau foi ona maitauina o paipa uʻamea e tusa ai ma tulaga GB / T20801 ma TSGD0001, GB3087 ma GB8163 e le tatau ona faʻaaogaina mo paipa GC1 (sei vagana ai le tasi i le tasi o le ultrasonic, o le lelei e le maualalo ifo i le L2.5, ma e mafai ona fa'aaogaina mo le GC1 ma le fa'aosoina o le mamanu e le sili atu nai lo le 4.0Mpa paipa).

（二）Low alloy paipa paipa u'amea seamless

I masini gaosiga petrochemical, o le chromium-molybdenum u'amea masani ma chromium-molybdenum-vanadium uamea seamless paipa uamea tulaga faatonuina o GB9948 "seamless paipa u'amea mo suauu ta'e" GB6479 "maualuga-miomiga seamless paipa uʻamea mo meafaigaluega fetilaisa" GB / T5310 "seamless. paipa u'amea mo le faumea maualuga》GB9948 o lo'o i ai togi mea uamea chromium-molybdenum: 12CrMo, 15CrMo, 1Cr2Mo, 1Cr5Mo, ma isi mea uamea maualuga togi meafaitino: 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12Cr1MoVG, ma isi. Faatasi ai ma i latou, o le mea e masani ona faʻaaogaina o le GB9948, vaʻai i luga mo tulaga filifilia

（三） paipa u'amea lamolemole

E masani ona fa'aaogaina paipa u'amea u'amea leai se fa'aogaina o:

E lima tulaga: GB/T14976, GB13296, GB9948, GB6479, ma GB5310.Faatasi ai ma i latou, e na o le lua pe tolu togi meafaitino uamea o loo lisiina i tulaga mulimuli e tolu, ma e le masani ona faaaogaina togi meafaitino.

O le mea lea, pe a faʻaaogaina tulaga faʻaogaina o paipa uamea e leai se mea e faʻaaogaina i le inisinia, e faʻaaogaina tulaga masani GB / T14976 ma GB13296.

GB/T14976 “Papa u’amea e leai se mea mo le felauaiga o le suavai”:

Fa'ailoga mea: 304, 304L ma isi ituaiga 19 e talafeagai mo felauaiga lautele o le suavai.
