Ole ASTM A179/ASME SA179?

ASTM A179 (ASME SA179) o se faagaau u'amea e leai ni fa'ameamea e fa'aogaina i totonu o mea fa'afefe vevela, condensers, ma fa'aoga fa'afefete tutusa.

ASTM A179 ma le ASME SA179 e lua tulaga e tutusa lelei.Mo le faʻaogaina o le faʻaogaina, ASTM A179 o loʻo faʻaogaina i lalo.

Fuafuaga

ASTM A179 e talafeagai mo paipa uʻamea ma le lautele fafo o le 1/8″ – 3″ [3.2mm - 76.2mm].

Uamea i laloose fa'ameamea paipa u'amea teu oloa mai Saina, ofoina atu ia te oe se filifiliga tele o le tulaga maualuga ASTM A179/ASME SA179 toso malulu uamea paipa.

Matou te faʻamaoni i le tuʻuina atu ia matou tagata faʻatau oloa ma auaunaga sili ona maualuga ina ia mautinoa o loʻo sologa lelei au galuega faatino.Filifili Botop Steel, ma filifili se paaga faatuatuaina.

Fa'agasologa o Gaosi

Ua uma ona matou taʻua o le A179 o loʻo gaosia e faʻaaoga ai le faʻaogaina o le faʻaogaina o le gaosiga o le malulu.O a fa'agasologa fa'apitoa o lo'o a'afia i le gaosiga e le'i fa'aogaina le malulu?Fa'amolemole va'ai le siata fa'agasologa o lo'o i lalo.

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

I le tulaga ASTM,A556fa'aoga fo'i le fa'agasologa o le gaosiga e le'i fa'apipi'iina le malulu ae fa'apitoa mo fa'avevela vai tubular.O i latou e fiafia e mafai ona suʻe atili.

Togafitiga vevela

A maeʻa le ata malulu mulimuli, ona faʻafefeina lea o paipa uʻamea i le vevela o le 1200°F [650°C] pe maualuga atu.

Su'ega Hydrostatic

O paipa ta'itasi e tatau ona faia i se su'ega o le mamafa o le hydraulic po'o, afai e fa'atonuina e le tagata fa'atau, e mafai ona fa'aaoga se su'ega eletise e le fa'aleagaina.

O le paipa u'amea e tumau pea le mamafa mo le itiiti ifo i le 5s e aunoa ma le tafe.

Ole fua ole su'ega e fa'atatau ile fa'atatau lea:
