I le aso 8 o Iulai, 2023, na matou auina atu ai paipa uʻamea seamless alloy ASTM A335 P92 i Italia, ma tuʻuina atu i le taimi atofaina. I le taimi nei, na matou faia ai ni afifiina ua faʻamalosia 100%, e aofia ai afifiina PVC, afifiina o taga lalagaina, ma afifiina o pepa ua faʻatumuina i le omomi, lea e mafai ona toe faʻaaogaina atoa. O fusi uʻamea e faʻaaogaina e fusi ai paipa, ma o paipa i tafatafa o ia paipa e faʻatumuina i pepa pupuni e teteʻe atu i fetoʻai ma pepa faʻatumu omomi, ma mulimuli ane teuina i totonu o pusa laupapa. I le pito i fafo o le pusa laupapa, matou te faʻaaogaina foʻi se fusi uʻamea malosi tele e faʻamau ai le pusa, ina ia puipuia ai totonu ma fafo o le paipa atoa.
O le tuʻuina atu o oloa mai tagata faʻatau Italia ua faʻataʻatia ai se faʻavae sili atu mo la matou maketi Europa, ma matou te tulimatai atu i la matou galulue faʻatasi e sosoo ai!
O le ASTM A335 P92 o se paipa uʻamea e leai ni soʻoga, lea e faʻaaogaina tele i laʻau eletise faʻavevela i tausaga talu ai nei, aemaise lava mo paipa ausa autu ma toe faʻavevela paipa ausa.
Fa'asologa o vaila'au A335 P92: C: 0.07~0.13 Si: ≤0.50 Mn: 0.30~0.60 P≤0.020 S≤0.010 Cr: 8.50~9.50 Mo: 0.30~0.60Ni≤0.40 V:0.15~0.25 N:0.03~0.07 Al: ≤0.02 Ti: ≤0.01 Zr≤0.01Nb: 0.04~0.09 W: 1.5~2.0 B: 0.001~0.006
ASTM A335 P92 meatotino fa'ainisinia o paipa u'amea u'amea e leai ni fa'alavelave: malosi fa'asolosolo ≥ 620Map, malosi fua ≥ 440Mpa, fa'aloaloa pe a uma ona gau ≥ 20%
ASEM SA335 P92 Tulaga o le Tu'uina Atu o Paipa U'amea Fa'a'au'au Seamless: Fa'atulagaina + Fa'amalūlūina
O le tele o le paipa u'amea u'amea ASEM A335 P92 e leai ni so'oga: 60.3-765*2-120, o lautele e masani ona fa'aaogaina e 60.3, 73, 88.9, 114.3, 168.3, 219.1, 273.1, 323.9, 355.6, 406.4, 457.2, 508, 559, 610, 660, 711, 762, ma isi lapopo'a e mafai fo'i ona fa'apitoa e tusa ai ma mana'oga o tagata fa'atau.
Fa'aoga autū o le paipa u'amea u'amea ASME SA335 P92: e fa'aaogaina tele i le gaosiga o superheaters ma reheaters mo seti generator tetele
Paipa u'amea fa'a-Amerika tulaga fa'atulagaina ASTMA335 e fetaui ma le vasega u'amea P11, P12, P5, P9, P91
O le A335 P11 o se tulafono fa'avae o meafaitino na tu'uina atu e le ASTM (American Society for Testing and Materials), ma o le tulaga fa'atonuina fa'ale-atunu'u talafeagai o le 15CrMo, o se mea u'amea fa'afefiloi.
O le ASTM A335 P5 e tutusa ma le u'amea fa'a'au'au i totonu o le atunu'u: 1Cr5Mo. O le fausaga u'amea o le 1Cr5Mo o le martensite, lea e tete'e lelei i le oxidation i le pe tusa ma le 650 tikeri Celsius, malosi lelei i le vevela i lalo ifo o le 600 tikeri Celsius, mitiia lelei le te'i ma le fa'avevela, ma e fa'aaogaina lautele i turbine ausa.
O le tulaga fa'atonuina Amerika astm a335p91 e tutusa ma le tulaga fa'atonuina fa'aleatunuu 10Cr9Mo1VNb. T91/P91 (10Cr9Mo1VNb)
Fa'atulagaga o meafaitino o le P91 (wt%):
C 0.08~0.12; Mn 0.30~0.60; Si 0.20~0.50; P ≤0.02; S ≤0.01; Cr 8.0~9.5;
