A335P92 hlau tsis muaj hlau yeeb nkab, qhov tshwj xeeb 48.3 * 7.14 (piv txwv li sab nraud txoj kab uas hla 48.3 hli, phab ntsa tuab 7.14 hli), ua lub raj xa dej siab siab, nws tus qauv siv yog ASTM A335M. Cov hauv qab no yog kev tshuaj xyuas ntxaws ntxaws ntawm cov yeeb nkab hlau:
I. Kev piav qhia yooj yim ntawm Cov Kav Hlau Boiler
A335P92 alloy seamless steel yeeb nkab yog ib hom yeeb nkab kub thiab siab siab alloy seamless steel yeeb nkab, uas yog siv dav hauv qhov kub thiab siab ib puag ncig xws li cov kav dej loj thiab cov kav dej rov ua kom sov ntawm cov chaw tsim hluav taws xob thermal. Nws cov khoom siv yog P92, uas yog tus lej hlau ASTM A335 P92 martensitic kub-resistant hlau.
Qhov thib ob, cov tshuaj lom neeg muaj pes tsawg leeg ntawm Cov Hlau Boiler Tubes
A335P92 alloy seamless steel yeeb nkab tshuaj lom neeg muaj pes tsawg leeg yog tswj tau meej, feem ntau suav nrog carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum, vanadium, nitrogen, nickel, txhuas, niobium, tungsten thiab boron thiab lwm yam ntsiab lus. Cov ntsiab lus tshwj xeeb yog raws li nram 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 tseg tias piv nrog SA-335P91 hlau, SA-335P92 hlau txo cov ntsiab lus ntawm Mo element, thiab txhim kho kev ua tau zoo 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%
Txhuas (Al): ≤0.04%
Niobium (Nb): ≤0.040 ~ 0.09%
Tungsten (W): 1.5 ~ 2.0%
Boron (B): 0.001 ~ 0.006%
Qhov sib piv tsim nyog ntawm cov ntsiab lus no ua rau A335P92 alloy seamless steel yeeb nkab muaj qhov kub zoo heev corrosion tsis kam, oxidation tsis kam, kub muaj zog thiab creep zog.
3. Cov khoom siv kho tshuab ntawm Cov Kav Hlau Boiler
A335P92 alloy seamless steel yeeb nkab muaj cov khoom siv kho tshuab zoo heev, uas tau qhia raws li hauv qab no:
Lub zog tensile: ≥620MPa
Lub zog tawm los: ≥440MP
Cov khoom siv kho tshuab no ua kom muaj kev nyab xeeb thiab kev ntseeg tau ntawm cov kav hlau hauv qhov kub thiab txias thiab qhov chaw siab.
4. Daim ntawv thov ntawm Steel Boiler Tubes
A335P92 alloy seamless steel yeeb nkab vim nws cov yam ntxwv ua tau zoo heev, yog siv dav hauv cov teb hauv qab no:
Lub Hoobkas Fais Fab Thermal: ua cov khoom siv tseem ceeb rau cov kav dej loj thiab cov kav dej rov ua kom sov, nws tuaj yeem tiv taus qhov kub thiab txias siab thiab qhov chaw siab kom ntseeg tau tias lub Hoobkas fais fab ua haujlwm zoo.
Petrochemical: Hauv cov txheej txheem ntawm kev ua roj av thiab kev tsim tshuaj lom neeg, nws yog siv los tsim cov khoom siv xws li reactors, cov cua sov sib hloov thiab cov kav dej xa mus rau qhov chaw kom ua tau raws li qhov yuav tsum tau ua ntawm qhov kub thiab txias thiab kev kub siab thiab kev tiv thaiv corrosion.
Kev lag luam fais fab nuclear: Hauv cov chaw tsim hluav taws xob nuclear, siv los tsim cov tshuab cua txias nuclear reactor thiab cov kav dej ntsig txog kom ntseeg tau tias muaj kev nyab xeeb thiab ruaj khov ntawm kev tsim hluav taws xob nuclear.
5. Cov qauv kev siv thiab cov lus qhia txog kev txiav txim ntawm Cov Kav Hlau Boiler
Cov yeeb nkab hlau A335P92 ua raws li tus qauv ASTM A335/A335M. Thaum xaj khoom, cov ntaub ntawv hauv qab no yuav tsum meej:
Qhov ntau (piv txwv li hauv ko taw, meters, lossis cov hauv paus hniav)
Lub npe khoom siv (seamless alloy steel nominal yeeb nkab)
Chav Kawm (P92)
Txoj kev tsim khoom (kub tiav los yog txias kos duab)
Cov Lus Qhia Tshwj Xeeb (piv txwv li sab nraud txoj kab uas hla, phab ntsa tuab, thiab lwm yam)
Qhov Ntev (qhov loj sib faib thiab qhov loj sib txawv)
Kev ua kom tiav
Cov kev cai xaiv (piv txwv li qhov siab ntawm dej thiab qhov hnyav uas tso cai hloov pauv)
Daim ntawv qhia txog kev xeem uas yuav tsum tau ua
Tus lej txheem
Cov kev cai tshwj xeeb lossis lwm yam kev cai ntxiv uas xaiv tau
Hauv kev xaus, A335P92 alloy seamless steel yeeb nkab yog cov yeeb nkab kub thiab siab siab alloy seamless steel yeeb nkab, uas siv dav hauv ntau qhov chaw nrog nws cov yam ntxwv ua tau zoo heev. Thaum xaj thiab siv, nws yog qhov tsim nyog ua raws li cov qauv thiab cov kev cai kom ntseeg tau tias nws muaj kev nyab xeeb thiab kev ntseeg siab.
