Tus qauv A106 hais txogASTM A106/A106Mtus qauv, uas yog tus qauv khoom rau cov kav hlau carbon seamless uas tau muab los ntawm American Society for Testing and Materials (ASTM International). Tus qauv no qhia txog cov kev cai rau kev siv cov kav hlau carbon seamless hauv qab qhov kub thiab txias thiab siab.
Tus qauv A106 siv rau cov chaw ua haujlwm kub siab hauv cov lag luam dav dav, xws li kev ua roj av, kev lag luam tshuaj lom neeg, chaw tsim hluav taws xob, boilers, cua sov thiab cov kav dej siab thiab lwm yam. Nws npog ntau qib ntawm cov yeeb nkab hlau carbon, suav nrog A, B, thiab C qib.
Raws li tus qauv A106, cov kav dej hlau carbon seamless yuav tsum muaj qee yam tshuaj lom neeg thiab cov khoom siv kho tshuab. Cov kev cai ntawm cov tshuaj lom neeg feem ntau suav nrog cov ntsiab lus carbon, cov ntsiab lus manganese, cov ntsiab lus phosphorus, cov ntsiab lus sulfur thiab cov ntsiab lus tooj liab. Cov kev cai ntawm cov khoom siv kho tshuab suav nrog lub zog tensile, lub zog tso zis, thiab elongation, thiab lwm yam. Tsis tas li ntawd, qhov loj me, qhov hnyav thiab qhov kev hloov pauv ntawm cov kav dej tau teev tseg.
Tus qauv A106 xav kom cov kav hlau carbon seamless yuav tsum muaj peev xwm tiv taus kev ntxhov siab hauv qab qhov kub thiab txias thiab siab, thiab muaj kev tiv thaiv corrosion zoo heev thiab hydrogen cracking tsis kam. Nws cov txheej txheem tsim khoom suav nrog kev kos duab txias, dov txias, dov kub lossis thermal nthuav dav, thiab lwm yam, kom ntseeg tau tias sab hauv thiab sab nraud ntawm cov yeeb nkab du thiab tsis muaj qhov tsis zoo.
Raws li cov kev cai ntawm A106 tus qauv, cov kav dej carbon seamless yuav tsum dhau los ntawm ntau qhov kev tshuaj xyuas thiab kev sim xws li kev tshuaj xyuas tshuaj lom neeg, kev sim kev ua haujlwm kho tshuab, kev tshuaj xyuas pom, kev ntsuas phab ntsa tuab, kev sim siab thiab kev tshuaj xyuas tsis puas tsuaj kom ntseeg tau tias lawv qhov zoo ua tau raws li cov qauv xav tau.
Xaus lus, tus qauv A106 yog tus qauv tseem ceeb ntawm cov yeeb nkab carbon steel seamless, uas qhia txog cov tshuaj lom neeg sib xyaw, cov khoom siv kho tshuab thiab cov txheej txheem tsim khoom ntawm cov yeeb nkab carbon steel, nrog rau kev tswj xyuas zoo thiab kev tshuaj xyuas. Kev ua raws li tus qauv no tuaj yeem ua kom ntseeg tau tias kev siv cov yeeb nkab carbon steel seamless hauv qhov kub thiab txias thiab qhov chaw siab.
Cov khoom uas tus neeg yuav khoom yuav lub sijhawm no yog cov yeeb nkab carbon steel ASTM A106 GR.C. Cia kuv qhia koj cov ntsiab lus tshwj xeeb ntawm kev ntsuas thiab kev tswj xyuas zoo ntawm tag nrho cov khoom.
Los ntawm qhov pom ntawm qhov tsos, peb xa daim duab tag nrho ntawm cov khoom rau tus neeg siv khoom, kom tus neeg siv khoom tuaj yeem pom daim duab ntawm lub raj kom meej dua. Hais txog qhov loj ntawm cov khoom thiab qhov tuab ntawm phab ntsa, peb muab daim duab ntsuas ncaj qha rau tus neeg siv khoom, raws li tus qauv, raws li qhia hauv daim duab:
Qhov txawv ntawmASTMA106GrB thiab ASTMA106GrC
Qhov sib txawv ntawm ASTM A106 GrB thiab ASTM A106 GrC: lub zog tensile txawv.
ASTM A106 GrB lub zog qib 415MPa. ASTM A106 GrC lub zog qib 485MPa.
ASTMA106GrB thiab ASTMA106GrC muaj cov kev cai sib txawv ntawm cov pa roj carbon
A106GrB cov ntsiab lus carbon ≤0.3, A106GrC cov ntsiab lus carbon ≤0.35
ASTM A106 GrB. Cov yeeb nkab hlau tsis muaj seamless sib raug rau tus qauv hauv tebchaws
ASTM A106Gr.B cov yeeb nkab hlau tsis muaj qhov sib txuas yog cov hlau uas tsis muaj carbon ntau uas siv dav hauv kev lag luam roj av, tshuaj lom neeg thiab boiler. Cov khoom siv muaj cov khoom siv kho tshuab zoo.
