A335 P91 Nqe lus piav qhia:
1) A335P91 yog cov khoom siv ntawm kev kub siab thiab kub resistant steel. P91 tuav, daim hlau, kav, yeeb nkab fittings, p91 feem ntau yog
hu ua A355P91, uas yog sib npaug rau lub teb chaws tus qauv 10Cr9Mo1VNb. Nws yog cov khoom siv ntawm kev kub siab thiab kub siab
resistant steel kav. Tus qauv Asmeskas yog ASME SA-335 / SA335M, lub zog tensile yog ≥ 585 (MPa), lub zog tawm los yog
≥ 415 (MPa), thiab elongation yog ≥ 20 (%). Tus yam ntxwv ntawm P91 yog tias phab ntsa thickness ntawm cov yeeb nkab yog nyias. Nyob rau hauv cov nqe lus ntawm
cov khoom siv, nws yog ntau dua 40% tsawg dua li ntawm lwm cov ntaub ntawv hlau, thiab nws yog ntau dua 30% tsawg dua ntawm kev txuag
cov ntaub ntawv thiab cov nqi installation. Txij li thaum tuag qhov hnyav ntawm P91 yeeb nkab yog txo, lub load ntawm kev txhawb nqa thiab hangers kuj tseem
txo qis, uas yooj yim rau kev txhawb nqa thiab nqa, thiab yooj yim rau kev tsim thiab teeb tsa.
2) Qhov sib thooj German steel qib ntawm T91 / P91 (10Cr9Mo1VNb) thiab P91 steel yog X10CrMoVNNb91, Japanese qib steel
yog HCM95, thiab Fabkis qib steel yog TUZ10CDVNb0901.
3) Nws tuaj yeem siv los ua cov kav hlau rau qhov kub thiab txias superheater thiab reheater nrog phab ntsa kub ≤ 625 ℃ hauv subcritical thiab
supercritical boilers, nrog rau kub kub header thiab chav kav nrog phab ntsa kub ≤ 600 ℃, thiab nuclear fais fab
heat exchanger thiab roj cracking unit rauv cov kav dej.

Ntim duab:
Daim ntawv thov:
Alloy raj yog tsuas yog siv rau cua sov saum npoo ntawm cov cua kub qis thiab nruab nrab siab boilers (feem ntau ua hauj lwm siab
tsis siab tshaj 5.88Mpa, thiab ua hauj lwm kub yog qis dua 450 ℃); Nws yog siv los ua cua sov cov kav dej, cov khoom lag luam,
superheaters, reheaters, kav dej rau kev lag luam petrochemical, thiab lwm yam ntawm high-pressure boilers (feem ntau lub siab ua hauj lwm yog
siab tshaj 9.8Mpa, thiab ua hauj lwm kub ntawm 450 ℃ thiab 650 ℃)
