I. Cov ntsiab lus tseem ceeb ntawm Steel Boiler Tubes
A335P92 alloy seamless steel yeeb nkab yog ib hom kev kub siab thiab siab siab alloy seamless steel yeeb nkab, uas yog dav siv nyob rau hauv kub thiab kub siab ib puag ncig xws li lub ntsiab chav pipeline thiab reheated chav pipeline ntawm thermal fais fab nroj tsuag. Nws cov khoom yog P92, yog nyob rau hauv Teb Chaws Asmeskas steel tooj ASTM A335 P92 martensitic tshav kub-resistant steel.

Thib ob, tshuaj muaj pes tsawg leeg ntawm Steel Boiler Tubes
A335P92 alloy seamless steel yeeb nkab tshuaj lom neeg muaj pes tsawg leeg yog tswj hwm, feem ntau suav nrog carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum, vanadium, nitrogen, nickel, aluminium, niobium, tungsten thiab boron thiab lwm yam khoom. Cov ntsiab lus tshwj xeeb yog raws li hauv qab no:

Cov pa roj carbon (C): 0.07 ~ 0.13%
Manganese (Mn): 0.30-0.60%
Phosphorus (P): ≤0.020%
Sulfur (S): ≤0.010%
Silicon (Si): ≤0.50%
Chromium (Cr): 8.5 ~ 9.50%
Molybdenum (Mo): 0.30 ~ 0.60% (tab sis nws tsim nyog sau cia tias piv nrog SA-335P91 steel, SA-335P92 hlau tsim nyog txo cov ntsiab lus ntawm Mo, thiab txhim kho kev ua haujlwm ntawm cov khoom los ntawm kev ntxiv qee qhov W)
Vanadium (V): 0.15 ~ 0.25%
Nitrogen (N): 0.03 ~ 0.07%
Nickel (Ni): ≤0.40%
Aluminium (Al): ≤0.04%
Niobium (Nb): ≤0.040 ~ 0.09%
Tungsten (W): 1.5 ~ 2.0%
Boron (B): 0.001 ~ 0.006%

Qhov tsim nyog feem ntawm cov ntsiab lus no ua rau A335P92 alloy seamless steel yeeb nkab muaj qhov kub thiab txias corrosion kuj, oxidation tsis kam, kub siab zog thiab creep zog.

3. Mechanical zog ntawm Steel Boiler Tubes
A335P92 alloy seamless steel yeeb nkab muaj cov khoom siv zoo heev, uas tau qhia raws li hauv qab no:

Tensile zog: ≥620MPa
Yield zog: ≥440MP
Cov khoom siv kho tshuab no ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov raj steel nyob rau hauv qhov kub thiab txias ib puag ncig.

4. Daim ntawv thov teb ntawm Steel Boiler Tubes
A335P92 alloy seamless steel yeeb nkab vim nws cov yam ntxwv ua tau zoo, yog dav siv hauv cov nram qab no:

Thermal fais fab nroj tsuag: raws li ib tug tseem ceeb cov ntaub ntawv rau lub ntsiab chav pipeline thiab reheated chav pipeline, nws muaj peev xwm tiv taus kub thiab kub siab ib puag ncig los xyuas kom meej kev ruaj ntseg ntawm lub fais fab nroj tsuag.

Petrochemical: Nyob rau hauv cov txheej txheem ntawm roj av refining thiab tshuaj ntau lawm, nws yog siv los tsim cov khoom xws li reactors, tshav kub exchangers thiab kis pipelines kom tau raws li qhov yuav tsum tau ntawm kub kub thiab siab thiab corrosion kuj.

Kev lag luam hluav taws xob Nuclear: Hauv cov chaw tsim hluav taws xob nuclear, siv los tsim cov tshuab hluav taws xob hluav taws xob cua txias thiab cov kav dej cuam tshuam los xyuas kom muaj kev nyab xeeb thiab ruaj khov ntawm kev tsim hluav taws xob nuclear.

5. Kev ua raws li cov qauv thiab kev txiav txim ntawm Steel Boiler Tubes
A335P92 alloy seamless steel yeeb nkab ua raws li ASTM A335 / A335M tus qauv tswj hwm. Thaum txiav txim, cov ntaub ntawv hauv qab no yuav tsum tau meej:

Qhov ntau (piv txwv li hauv ko taw, meters, lossis hauv paus)

Khoom npe (seamless alloy steel nominal yeeb nkab)
Chav Kawm (P92)

Txoj kev tsim khoom (kub tiav lossis kos duab txias)
Specifications (xws li sab nraud txoj kab uas hla, phab ntsa thickness, thiab lwm yam)
Length ( faib qhov loj me thiab qhov sib txawv)
Xaus machining
Cov kev cai xaiv (xws li dej siab thiab qhov sib txawv qhov hnyav)
Daim ntawv xeem yuav tsum tau
Txheem naj npawb
Cov kev cai tshwj xeeb lossis lwm yam kev xav tau ntxiv

Nyob rau hauv cov ntsiab lus, A335P92 alloy seamless steel yeeb nkab yog ib tug high-zoo kub thiab siab siab alloy seamless steel yeeb nkab, uas yog dav siv nyob rau hauv ntau lub teb nrog nws zoo heev cov yam ntxwv. Thaum txiav txim thiab siv, nws yog ib qho tsim nyog yuav tsum ua raws li cov qauv tsim nyog thiab cov kev cai kom ntseeg tau tias nws muaj kev nyab xeeb thiab kev ntseeg tau.
