Xaus Lus: Kev Npaj Ua Ntej Rau Kev Hloov Pauv Lag Luam
Qhov kev siv daim ntawv tso cai xa khoom tawm uas tau kwv yees tseg sawv cev rau ob qho tib si kev ua raws li txoj cai thiab cov cib fim txheeb xyuas qhov zoo rau kev yuav cov yeeb nkab hlau. Los ntawm kev tsim cov txheej txheem pov thawj pob tshab thiab txhawb kev sib raug zoo ntawm cov neeg muab khoom tam sim no, cov neeg yuav khoom thoob ntiaj teb tuaj yeem tswj hwm txoj cai hloov pauv tau zoo thaum nrhiav tau cov khoom siv txhim khu kev qha ntawm cov yeeb nkab hlau tsis sib xws, cov yeeb nkab hlau carbon, thiab cov yeeb nkab hlau tshwj xeeb rau xyoo 2026 cov haujlwm.
Tiv tauj peb pab neeg muag khoom thoob ntiaj teb kom tau txais kev tshuaj xyuas tshwj xeeb txog seb cov kev txhim kho no cuam tshuam li cas rau koj cov yeeb nkab seamless, yeeb nkab welded, thiab cov raj xa khoom xav tau. Peb muab cov kev hloov tshiab hauv kev lag luam, kev txhais lus txoj cai, thiab kev tsim cov tswv yim yuav khoom rau cov kav dej roj thiab roj av, cov tshuab tsim hluav taws xob, thiab cov ntawv thov hauv kev lag luam.
ASTM A106 Qib BCov yeeb nkab hlau tsis muaj qhov txuas yog cov yeeb nkab hlau carbon uas muaj qhov kub siab thiab tsis muaj qhov txuas hauv American Society for Testing and Materials tus qauv, uas feem ntau siv rau kev thauj mus los ntawm cov kua dej hauv qab qhov kub thiab txias thiab qhov siab. Cov ntaub ntawv sib xws hauv Suav teb feem ntau yog hais txog tus qauv hauv tebchaws Suav (GB) thiab cov qauv kev lag luam, thiab yuav tsum tau sib phim los ntawm peb lub zeem muag: cov tshuaj lom neeg sib xyaw, cov khoom siv kho tshuab, thiab cov xwm txheej siv.
Feem ntau muaj ob txoj kev xaiv rau kev sib piv cov khoom siv hauv tsev:
Cov khoom siv thawj zaug: 20 hlau (GB / T 8163)
20 hlau yog cov hlau carbon ib txwm muaj, uas yog cov khoom siv dav dav hauv GB / T8163 tus qauv thiab tsim nyog rau kev thauj mus los ntawm cov kua dej dav dav. Kev sib piv ntawm cov tshuaj lom neeg: ASTM A106 Gr.B muaj cov ntsiab lus carbon (C) ntawm 0.17-0.24%, thiab manganese (Mn) ntawm 0.29-1.06%; 20 hlau muaj cov ntsiab lus carbon ntawm 0.17-0.24%, thiab cov ntsiab lus manganese ntawm 0.35-0.65%. Cov ntsiab lus carbon ntawm ob qho yog ze, tab sis cov ntsiab lus manganese ntawm ASTMA106 Qib Bmuaj qhov siab dua qhov txwv thiab kev ua haujlwm kub zoo dua.
Kev sib piv cov khoom siv kho tshuab: ASTM A106 Gr.B muaj lub zog tensile ntawm >415MPa thiab lub zog yield ntawm >240MPa; 20 hlau muaj lub zog tensile ntawm >410MPa thiab lub zog yield ntawm >245MPa. Cov ntaub ntawv zoo sib xws tab sis qhov kub thiab txias siv tau sib txawv.
Kev txwv tsis pub siv: 20 hlau yog tsim rau cov xwm txheej ua haujlwm nrog qhov kub tsim qis dua 350 ℃ thiab qhov siab qis. Yog tias siv rau qhov kub thiab siab siab (xws li cov kav dej boiler), yuav tsum xaiv cov khoom siv siab dua.
Cov khoom siv thib ob sib xws: 20G (GB 5310)
20G yog cov yeeb nkab hlau tsis muaj seamless rau cov boilers siab, uas yog tus qauv GB 5310 thiab tsim nyog rau cov tshuab ua pa kub thiab siab.
Kev sib piv ntawm cov tshuaj lom neeg:20Gmuaj cov ntsiab lus carbon ntawm 0.17-0.24%, cov ntsiab lus manganese ntawm 0.35-0.65%, thiab kev tswj hwm nruj dua ntawm cov phosphorus thiab sulfur cov ntsiab lus, uas yog sib xws nrog cov ntsuas ntawm ASTMA106 Gr.B.
Kev sib piv ntawm cov khoom siv kho tshuab: 20G lub zog tensile yog ≥410MPa, thiab nws lub zog tawm los yog >245MPa, uas yuav luag zoo ib yam li ASTM A106 Gr.B, thiab qhov kub ua haujlwm tso cai yog txog li 450 ℃.
Cov xwm txheej ntawm daim ntawv thov: 20G feem ntau siv rau hauv cov kav dej boiler ntawm cov chaw tsim hluav taws xob thermal thiab cov khoom siv tshuaj lom neeg siab, thiab tuaj yeem hloov ASTM A106 Gr.B rau tib yam kev ua haujlwm.
Kev ceev faj hloov 1. Qhov sib txawv ntawm tus qauv: ASTM A106 Gr.B xav tau kev sim tensile transverse thiab kev sim flattening, thaum GB/T 8163 tsuas yog xav tau kev sim tensile longitudinal. Thaum hloov, nws yog qhov tsim nyog los xyuas kom meej tias cov khoom sim puas ua tau raws li qhov yuav tsum tau ua.
2. Cov kev cai kho cua sov: ASTM A106 Gr.B feem ntau xa tuaj rau hauv lub xeev kub-kub, 20G xav tau kev kho mob normalizing, thiab cov txheej txheem yuav tsum tau hloov kho yog tias hloov.
3. Cov kev cai ntawm daim ntawv pov thawj: Yog tias qhov project xa tawm qhia txog cov khoom siv tus qauv Asmeskas, nws yog ib qho tsim nyog los paub meej nrog cov neeg siv khoom seb puas lees txais qhov kev hloov pauv tus qauv hauv tebchaws. Qee qhov project yuav xav tau kev tshuaj xyuas ntxiv los ntawm lwm tus neeg.
Cov ntaub ntawv siv tau
Ib lub tuam txhab petrochemical tau yuav cov kav dej ASTM A106 Gr.B rau kev thauj roj kub siab. Vim yog lub voj voog xa khoom ntev, nws hloov mus rau cov khoom siv 20G. Tom qab kev sim sab nraud, qhov cuam tshuam tawv (-20 ℃ KV2234J) thiab lub zog kub siab (lub zog tso zis> 180MPa ntawm 450 ℃) ntawm 20G ua tau raws li qhov yuav tsum tau tsim, thiab qhov project tau txais.
Kev Txheeb Xyuas
ASTM A106 Gr.B tuaj yeem sib haum rau 20 hlau (kev ua haujlwm dav dav) lossis 20G (kev ua haujlwm kub thiab siab siab). Thaum hloov pauv, nws yog qhov tsim nyog los ua ke cov qauv kub, siab thiab kev xeem tshwj xeeb. Nws raug pom zoo kom muab qhov tseem ceeb rau cov khoom siv 20G, uas nws cov tshuaj lom neeg thiab kev ua tau zoo ze rau cov qauv ntawm Tebchaws Meskas thiab muaj ntau yam kev siv.
