ASTM A335 Alloy Uamea Su'ega Paipa
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.
Ua matou sauni e faʻasoa atu lo matou malamalama i faʻasalalauga i le lalolagi atoa ma fautuaina oe i oloa talafeagai i tau faʻatauga sili ona malosi.O lea la ua tu'uina atu e Profi Tools ia te oe le tau sili o tupe ma ua matou sauni e gaosia fa'atasi ma le ASTM A335Alloy Seamless Paipa Uamea, O le tulaga lelei o le olaga o le falegaosimea, Taulai atu i manaoga o tagata faatau o le puna lea o le ola ma le atinaʻeina o kamupani, Matou te pipii atu i le faʻamaoni ma le faʻamaoni galue uiga, tulimatai atu i lou sau!

Malosi o le tetee i le malepelepe i le maualuga o le vevela ma le maualuga o le mamafa.
E mafai ona fa'aoga mo Au'aunaga Fa'a'ele'ele Hydrogen Sulfide.
Tetee i le ta'e mai le hydrogen osofaiga ma le embrittlement.
Tetee i le vevela sulfide corrosion ta'e.
E mafai ona fa'aoga mo Talosaga NACE o lo'o iai si'osi'omaga oona i lalo ole vevela ma le mamafa.
E mafai ona fa'aoga ile NACE-MRO 175 Sour Service.
Lelei mo talosaga fetolofi rupture.
E mafai ona taulimaina le maualuga o le vevela ma le maualalo tele.
O ituaiga u'amea u'amea o lo'o ufiufi e le ASTM A335 - ASME SA335 fa'amatalaga ua mamanuina i le "P" prefix, mai le P5 i le P92.Vasega P11/P22 ma le P91/92 e masani ona maua i nofoaga eletise, ae o le vasega P5 ma le P9 e sili atu ona taatele mo le faʻaogaina i totonu o fale gaosi oloa.Vasega P9, P91 o loʻo i totonu o le lisi, e sili atu le taugata
