O le a le ASTM A252?

ASTM A252 o se tulaga faʻapitoa na atiaʻe mo le faʻaogaina o paipa paipa paipa.

ASTM A252 fa'aoga i fa'aputuga paipa o lo'o galue ai le pa'u u'amea o se sui tumau e amoina uta, po'o se atigi e fausia ai fa'aputu sima.

Vasega 2 ma vasega 3 e lua o nei togi.

ASTM A252 Vasega

A252 ua vaevaeina i ni togi se tolu ma faʻasolosolo faʻaleleia mea faʻainisinia.

O i latou ia: Vasega 1, Vasega 2, maVasega 3.

Vasega 2 ma le Vasega 3 o togi e masani ona fa'aoga i le ASTM A252, ma matou fa'amatala au'ili'ili meatotino o togi e lua.

Gaosiga Fa'agasologa

ASTM A252e mafai ona gaosia e ala i seamless, uelo tetee, uelo moli, po o faiga uelo fusi.

I totonu o fa'aputuga paipa, fa'au'u u'amea e leai ni fa'auiga e maua ai le lagolago sili ona o lo latou malosi maualuga ma uiga tutusa o le malosi.

E le gata i lea, o paipa uʻamea e le faʻaogaina e mafai ona gaosia i le mafiafia o puipui mafiafia, lea e mafai ai ona latou tatalia le mamafa tele, faʻaleleia atili lo latou faʻalagolago i fausaga lagolago.

fa'agasologa-paipa-u'amea

Ae ui i lea, e mafai ona gaosia paipa u'amea e oo atu i le maualuga maualuga o le 660 mm, lea e fa'atapula'a ai lo latou fa'aogaina i talosaga e mana'omia ai fa'aputu tetele tetele.I lenei tulaga,LSAW(Longitudinal Submerged Arc Welded) maSSAW(Spiral Submerged Arc Welded) paipa uamea e sili atu ona lelei.

Fa'avasegaga o vaila'au o le ASTM A252 Vasega 2 ma le Vasega 3

Ole mea ole phosphorus e le sili atu ile 0.050%.

E leai se isi elemene e manaʻomia.
