ASTM A335 Alloy Steel Seamless Paipa

ASTM A335 Alloy Steel Seamless Pipe Fa'aalia Ata

Fa'amatalaga Puupuu:

ASTM A335 e masani ona taʻua o le paipa moly chrome ona o le vailaʻau o loʻo i ai le Molybdenum (Mo) ma le Chromium (Cr).Molybdenum faʻateleina le malosi o le uamea ma Chromium (poʻo le chrome) o le mea taua lea o le uʻamea uʻamea.O le tu'ufa'atasiga o le paipa u'amea chrome moly aloia e fa'aoga lelei mo le fa'aoga i fale eletise, fale fa'amamā, fale kemikolo penisini, ma auaunaga tau suau'u lea e felauai ai vai ma kasa i le maualuga o le vevela ma le mamafa.

Togafitiga vevela

Alloy Steel paipa e faʻafefeteina e maua ai mea faʻainisinia e tusa ai ma le mea e manaʻomia.O lo'o i lalo nisi o ituaiga o togafitiga vevela.

Fa'amasani tineia ma fa'avevela.

Tinei ma Fa'asa.

Fa'asalaina & Fa'amalo.

Su'ega Manaoga

Fa'asa'o/fa'apa'u: fa'atete'e ma fa'amafola, ma'a'a, su'ega pi'o-mo mea na fa'avevela i totonu o ogaumu, o nei su'ega e tatau ona faia i luga o le 5% o paipa mai numera ta'itasi vevela.Mo fasi fanua laiti, e tasi le paipa i lalo ifo e tatau ona su'eina.

ASTM A335 Gr.P91 e tatau ona i ai le maaa o le 250 HB / 265 HV (25 HRC).

Su'ega vai: e tatau ona fa'aoga i umi uma o paipa.

Ole su'ega eletise e le fa'aleagaina e filifili.
