ASTM A252 Vasega 3 Va'aiga lautele

ASTM A252 Vasega 3o le mea sili ona taatele o loʻo faʻaaogaina e avea o se paipa faʻaputuga.

Vasega 3 paipa paipa uʻamea e le faʻatapulaʻaina i se faʻagasologa o le gaosiga faʻapitoa ma e mafai ona gaosia e faʻaaoga ai auala eseese o paipa, e aofia ai.SMLS(seamless),SA(fa'aluulu arc uelo), maEFW( fa'afefiloi eletise uelo).O lenei fetuutuuna'i e mafai ai ona fa'afetaui i mana'oga fa'ainisinia eseese ma fa'ata'ita'iga fa'aoga.

I le avea ai ma vasega maualuga i le tulaga A52, o loʻo i ai mea faʻainisinia sili ona lelei ma le maualalo o le malosi o le 310 MPa ma le laʻititi laʻititi malosi o le 455 MPa ma e mafai ona faʻaaogaina e avea o se vaega tumau e amoina uta poʻo se atigi mo le lafo i totonu. -tuu faaputuga sima.

I'uga paipa

O fa'aputuga paipa e tatau ona fa'ata'atia.

O pito e tatau ona tipi afi poʻo masini-oti ma faʻamalo.

I le tulaga opito pi'opi'o, e tatau ona i ai le tulimanu o le pito u'amea30 - 35°.

Oa Tatou Oloa Fa'atatau

Uamea i laloofoina atu le tele o tulaga maualuga ASTM A52 paipa uamea.Fa'amolemole lagona le saoloto e fa'afeso'ota'i matou mo au mana'oga.

Mea Mata

O le uamea e tatau ona faia e se tasi poʻo le sili atu o faʻagasologa o loʻo taʻua i lalo: faʻagogo matala, faʻavae-oxygen, poʻo le ogaumu eletise.

Fa'agasologa o le gaosiga o le ASTM A252

A252 e tatau ona faia e leleai se su'ega, fa'afefe eletise uelo, uila uelo, pefusuaga uelofaiga.

O su'iga o fa'aputu paipa uelo e tataufaaumiumi, u'u-u'u, pevae-moe.

Ina ia mautinoa le lelei ma le faʻatinoina o paipa uʻamea, e taua tele le filifilia o le gaosiga saʻo.

O le LSAW (SAWL) faʻagasologa e lelei mo le tele-diameter, mafiafia-puipui paipa uʻamea, aemaise lava i galuega faufale ma atina'e tetele e mana'omia ai le maualuga o le gafatia o le amoina ma le loloto o le fausiaina o faavae.Ona o lona malosi sili atu, gafatia e ave ai uta, ma le loloto o le fetuutuunai, e mafai ona faʻafetaui i le tele o tulaga faʻalavelave faʻafanua aʻo tuʻuina atu faʻamanuiaga o le faʻapipiʻi vave ma le tumau umi.

LSAW paipa uamea faiga gaosiga

JCOEo se faiga masani masani i le gaosiga o le LSAW paipa uamea, lea e i ai le lelei o le maualuga maualuga, maualuga tulaga lelei, tele gafatia gaosiga, fua saʻo, fetuutuunai, ma le tamaoaiga, lea na faia ai le faiga o paipa sili ona lelei i le tele o mea tetele- fua fa'ainisinia poloketi.

Vaega Kemisi o le ASTM A252 Vasega 3

 

O le uamea e tatau ona i aie le sili atu i le 0.050% phosphorous.

O le faʻatapulaʻaina o le phosphorus i totonu o le uʻamea o le faʻamautinoa lea o loʻo i ai i le sila ni mea faʻainisinia lelei, aemaise lava pe a faʻaaogaina mo faʻaoga faʻavae e pei o le faʻaputuina o fale.

O lenei tapulaʻa e fesoasoani e puipuia ai le sila mai le maʻaleʻale i le maualalo o le vevela, ma faʻamautinoa ai lona saogalemu ma le faʻamaoni i le faʻaaogaina.

Mo isi elemene elemene, e leai ni mea e manaʻomia.

E mafua ona o le taulaiga autu o paipa paipa o le faʻamautinoaina o paipa e lava le malosi faʻavae ma le faigata, o mea taua ia mo le faʻaogaina i fausaga lagolago.
