Ole ASTM 210/ASME SA210 Vasega C?

ASTM A210 Vasega C (ASME SA210 Vasega C) ose fa'alava uamea fa'alava-carbon fa'alava ua fa'atulagaina fa'apitoa mo le fa'aoga i le gaosiga o paipa fa'avevela ma fa'aauala, e aofia ai pito saogalemu, puipui o le ogaumu ma paipa lagolago, ma paipa fa'avevela.

O le Vasega C o loʻo i ai ni mea faʻainisinia lelei, faʻatasi ai ma le malosi faʻamalosi o le 485 MPa ma le malosi o le gaosiga o le 275 MPa. O nei mea totino, faʻatasi ai ma se vailaʻau faʻapitoa talafeagai, faʻapipiʻi ASTM A210 Grade C tubes e fetaui lelei mo le faʻaaogaina i le maualuga o le vevela ma le maualuga- si'osi'omaga fa'amalosi ma mafai ona tatalia omiga e fa'atupuina e ala i le fa'avela.

Gaosiga Fa'agasologa

O paipa e tatau ona faia e ala i le faʻaogaina o le faʻagasologa ma e tatau ona faʻamaeʻaina poʻo le malulu.

O lo'o i lalo le fa'asologa o le fa'agasologa o le gaosiga mo le fa'amaluluina o le paipa u'amea fa'alelei:

Fa'agasologa o le gaosiga o paipa u'amea malūlū

O le a la le ese'esega i le va o le paipa u'amea fa'avela vevela ma le malulu ma fa'afefea ona e filifilia?

Ua mae'a vevelapaipa uamea seamless o se paipa uʻamea e taʻavale pe tuʻia i se vevela maualuga ma isi faiga ma faʻamalulu saʻo i le vevela potu.O paipa uamea i lenei setete e masani lava ona sili atu le malosi ma le malosi, ae o le tulaga maualuga atonu e le lelei e pei o paipa uʻamea malulu ona o le togafitiga vevela e mafai ona oʻo atu ai i le faʻamaʻiina poʻo le decarburization o le pito i luga ole paipa uʻamea.

Ua mae'a malulupaipa uamea seamless faasino i le faagasologa mulimuli o paipa uʻamea e ata malulu, taʻavale malulu, ma isi faiga i le vevela potu.O paipa u'amea ua mae'a malulu e maualuga le sa'o atoatoa, ma lelei le tulaga lelei, ma talu ai ona o le malulu e mafai ona fa'aleleia atili ai le malosi ma le ma'a'a'a o le paipa uamea, o mea fa'ainisinia o paipa u'amea ua mae'a malulu e masani lava ona sili atu nai lo paipa u'amea vevela. .Ae ui i lea, o se aofaʻi o faʻamaʻi totoe e mafai ona faʻatupuina i totonu o le paipa uʻamea i le taimi o galuega malulu, lea e manaʻomia ona faʻaumatia e ala i togafitiga vevela mulimuli ane.

Togafitiga vevela

O paipa u'amea ua mae'a vevela e le mana'omia ni togafitiga vevela.

O paipa ua mae'a mālūlū e tatau ona fa'a'ele'ele, fa'a'ele'ele atoa, po'o le vevela masani e togafitia pe a mae'a le fa'auma mālūlū mulimuli.

Malosi

Vasega C: 89 HRBW (Rockwell) po'o le 179 HBW (Brinell).

Manaomia Su'ega Fa'ainisinia

O paipa u'amea ta'itasi e tatau ona faia i se su'ega o le mamafa o le hydrostatic po'o se su'ega eletise e le fa'aleagaina.

Ole su'ega ole su'ega ole hydrostatic e fa'atatau ile ASTM 450, mea 24.

O mana'oga fa'ata'ita'iga e le fa'aleagaina e feso'ota'i ma le eletise e tusa ai ma le ASTM 450, mea 26.

Fa'atulagaina o Galuega

O le faʻatulagaina o gaioiga e manaʻomia mo paipa faʻapipiʻi e faʻamautinoa ai o loʻo faʻamalieina e ia faʻauluuluga manaʻoga faʻapitoa o le faiga faʻapipiʻi.

Pe a fa'aofi i totonu o le fa'avela, o paipa e tatau ona fa'alautele ma fa'asolo e aunoa ma le fa'aalia o ta'e po'o ni faaletonu.A fa'aogaina lelei, e tatau ona tutu fa'alava fa'alavalava.uelo.ma fa'agaioiga punou e mana'omia mo le fa'aogaina e aunoa ma ni fa'aletonu.

Fa'atulagaina o Galuega

O le Botop Steel o se kamupani paipa uʻamea sili ona lelei ma faʻatau mai Saina, faʻapea foʻi ma se faʻatau paipa uʻamea, e tuʻuina atu ia te oe le tulaga maualuga, faʻamaonia, ma le faʻatauvaʻa tau paipa.
