ASTM A106 Seamless Yeeb Nkab rau Siab -Kev Pabcuam Kub
ASTM A106 carbon steel yeeb nkab yog muaj nyob rau hauv tua- steel Qib A, B thiab C nrog qhov tsawg kawg nkaus yield zog ntawm 205, 240 thiab 275 MPa. Qib B (UNS K03006) yog lub neej ntawd xaiv rau lub hwj chim, refinery thiab boiler piping, thaum Qib C ntxiv zog qhov twg phab ntsa thickness tseem ceeb. Cov yeeb nkab yog muab rau hauv NPS 1/8–48 thiab Teem caij 10–160/XXS, yog ASME SA106 sib npaug, thiab xa nrog EN 10204 3.1/3.2 daim ntawv pov thawj. Qhia peb koj qib, qhov loj me thiab lub sijhawm, thiab peb yuav lees paub qhov kev qhia tshwj xeeb thiab xa rov qab ib nqe lus nrog lub sijhawm ua haujlwm.
ASTM A106 txhais tau li cas
A106 seamless carbon steel yeeb nkab yog tsim los rau ASTM A106 (Specification A106/A106M), US tus qauv rau siab -kev pab kub. Qhov sib npaug ASME yogSIB-106, tau txais ncaj qha rau hauv BPVC; technically ob yog zoo tib yam rau tib tsab. Tus qauv yog cov khoom siv ua ntej rau chav boiler, boiler thiab txheej txheem piping vim nws ua ke seamless kev ncaj ncees nrog kev kwv yees siab siab - qhov kub thiab txias. Lub npe nws tus kheej - "High-Kev Pabcuam Kub" - yog cov lus cog tseg: cov yeeb nkab tau tsim nyog rau kev txhawb nqa siab siab - kub siab lub luag haujlwm, tsis zoo li dav dav - cov kav dej.
A / B / C=qib ntaiv.Cov pa roj carbon thiab lub zog nce los ntawm A (205 MPa tawm los) txog B (240 MPa, tus neeg ua haujlwm) mus rau C (275 MPa). Qib B npog feem ntau ntawm ASME B31.1 thiab B31.3 daim ntawv thov.
Seamless nkaus xwb.A106 yog tsim los ntawm kev sib tsoo, tsis txhob siv vuam; tsis muaj ERW lossis SAW version ntawm A106. Qhov no tshem tawm cov longitudinal weld raws li ib tug qaug zog los yog tshuaj ntsuam kuj sib txawv.
Tua steel los ntawm lub neej ntawd.Silicon yog teev raws li qhov tsawg kawg nkaus ntawm 0.10%, uas ua rau tag nrho deoxidation - cov qauv nplej zoo ib yam thiab txhim khu kev qha ntawm qhov kub thiab txias. Qhov no kuj yog txoj kev huv tshaj plaws los qhia A106 los ntawm A53.
Graphitization yog nyob ntawm radar.Nco tseg 1 ntawm tus qauv ceeb toom rau cov neeg siv kom xav txog qhov ua tau graphitization thaum lub sij hawm ntev - lub sij hawm siab - qhov kub thiab txias, yog li kev siv lub neej ntev ntawm qhov kub yuav tsum tau tshuaj xyuas.
Hauv UNS system, Qib B yog A106 UNS K03006, nrog Qib A li K02501 thiab Qib C li K03501.

Ob qho A106 qhov ntsuas kub thiab A106 tso cai rau kev ntxhov siab poob nrog qhov ntsuas kub, yog li A106 siab ntsuas ntawm 400℃yog qhov zoo hauv qab chav tsev -tus nqi kub. Cov neeg sawv cev qhov tseem ceeb no yog los ntawm ASME B31.3 Table A-1 rau A106 Qib B, thiab koj yuav tsum nco ntsoov lees paub lawv tawm tsam tsab ntawv teev npe hauv koj qhov project specification. ASME B31.3 tso cai A106 Qib B mus txog 425℃(800℃F), tab sis qhov kev ntxhov siab tso cai tau poob mus rau 82 MPa ntawm qhov taw tes ntawd - kwv yees li 60% ntawm chav tsev-tus nqi kub. Cov tswv yim txuas ntxiv- kev pabcuam qab nthab yog li 425℃; saum toj no, kev tswj kev nkag thiab qis- cov qib alloy xws li ASTM A335 P11, P22 lossis P91 raug pom zoo. Kev raug mob mus ntev kuj ua rau muaj kev pheej hmoo ntawm graphitization, uas tus qauv A106 nws tus kheej chij hauv Note 1.
Dimensional Tolerances
ASTM A106 yeeb nkab qhov ntev khiav ntawm NPS 1/8 txog 48 nrog rau sab nraud rau ASME B36.10M; lub A106 yeeb nkab phab ntsa thickness thiab sab nraud - txoj kab uas hla tolerances yog muab hauv qab no.
| Dimension | Ua siab ntev |

FAQ:
ASTM A106 carbon steel yeeb nkab yog dab tsi?
ASTM A106 carbon steel yeeb nkab (Specification A106/A106M) yog seamless yeeb nkab ua rau siab - kev pab kub. Nws suav nrog peb tua- qib steel - A, B thiab C - nrog qhov muaj zog tsawg kawg nkaus ntawm 205, 240 thiab 275 MPa (30, 35 thiab 40 ksi) thiab lub zog tensile yam tsawg kawg nkaus ntawm 330, 415 thiab 485 MPa feem. Qhov sib npaug ASME yog SA-106, thiab cov yeeb nkab tau muab rau hauv NPS 1/8 txog 48 qhov ntau thiab tsawg thiab Teem caij 10 txog 160 / XXS.
Dab tsi yog qhov txawv ntawm ASTM A106 thiab A53?
Ob leeg sib koom tib chav kawm qib B- qhov kub thiab txias (240 MPa tawm los, 415 MPa tensile), tab sis ASTM A106 yog seamless nkaus xwb, yuav tsum tau tua hlau (Si 0.10 % min), npaj rau siab - qhov kub thiab txias kev pab cuam, thiab hais los ntawm ASME B31.1, Seamless beM 31.31. S) lossis hluav taws xob-kuj{11}}welded (Hom E), tsis tas yuav tsum tua, thiab yog ib qho kev qhia dav dav - kev pabcuam. A106 kuj muaj Qib C (275 MPa tawm los) uas A53 tsis muaj. Yog tias koj qhov tshwj xeeb hu rau A106, tsis txhob txais A53 lossis API 5L ua qhov sib npaug.
Cov tshuaj muaj pes tsawg leeg ntawm A106 Qib B yog dab tsi?
Ladle- tsom xam maxima rau A106 Qib B yog carbon 0.30 %, manganese 0.29–1.06 %, phosphorus 0.035 %, sulfur 0.035 %, nrog silicon teev tsawg kawg yog 0.10 % (tus tua- hlau marker). Residual txwv yog tooj liab, npib tsib xee thiab chromium txhua 0.40% max, molybdenum 0.15% max thiab vanadium 0.08% max. Cov txheej txheem tsuas yog qhov tsawg kawg nkaus rau silicon thiab tsuas yog maxima rau lwm yam, yog li tsis txhob sau silicon lossis lub zog tensile raws li qhov ntau.
Dab tsi yog cov khoom siv kho tshuab ntawm A106 Qib B?
A106 Qib B muaj qhov tsawg kawg nkaus lub zog ntawm 240 MPa (35 ksi), lub zog tensile yam tsawg kawg nkaus ntawm 415 MPa (60 ksi) thiab qhov tsawg kawg nkaus elongation ntawm 30% ntawm 2 hauv (50 mm) ntsuas qhov ntev. Cov lus qhia tshwj xeeb tsuas yog qhov tsawg kawg nkaus rau kev tawm los thiab tensile - tsis muaj qhov txwv siab - yog li qhov tensile ntau yam xws li 415–550 MPa yog qhov tsis raug. Qib C nce qhov tawm los rau 275 MPa (40 ksi) thiab tensile rau 485 MPa (70 ksi).
Qhov kev pabcuam siab tshaj plaws ntawm A106 yeeb nkab yog dab tsi?
ASME B31.3 tso cai A106 Qib B mus txog 425℃(800℃F), tab sis qhov tso cai kev ntxhov siab derates nrog kub: 138 MPa ntawm 100 degree, 118 MPa ntawm 300 degree, 96 MPa ntawm 400℃thiab 82 MPa ntawm 425 degree. Kev ua haujlwm tas mus li - kev pabcuam qab nthab yog li 425℃; saum toj no, kev tswj kev nkag thiab qis- qib alloy xws li ASTM A335 P11, P22 lossis P91 raug pom zoo. Ntev -lub sij hawm raug kuj ua rau muaj kev pheej hmoo ntawm graphitization, uas tus qauv A106 nws tus kheej chij hauv Note 1.
Dab tsi qhov ntev thiab phab ntsa -thickness kam rau ua A106 yeeb nkab muaj?
A106 yeeb nkab yog tsim nyob rau hauv NPS 1/8 txog 48 (DN 6 mus rau 1200) nrog sab nraud diameters rau ASME B36.10M thiab phab ntsa hauv Teem caij 10, 20, 30, 40, 60, 80, 100, 120, 140, 160 thiab XXS Phab ntsa-thickness kam rau ua yog rho tawm 12.5% ntawm nominal (cov yeeb nkab yuav tsis thinner tshaj qhov ntawd); cov specification tsis txwv tshaj -thickness, uas yog tswj los ntawm qhov hnyav kam rau ua. Sab nraud- txoj kab uas hla yog ± 0.4 hli rau NPS 1/8–1½ thiab ± 1% ntawm sab nraud txoj kab uas hla rau NPS 2–48.
Puas yog A106 Qib B haum rau qis- qhov kub thiab txias kev pabcuam?
Tsis yog. Standard A106 Qib B tsis pom zoo hauv qab no txog -29℃(-20℃F) vim tias cov hlau tsis muaj qhov tsis zoo thiab tuaj yeem ua rau muaj kev cuam tshuam. Rau qhov kub thiab txias los yog cryogenic cov kev pab cuam, qhia cov qib qis-kub xws li ASTM A333 Qib 6, uas khaws cov toughness mus rau -45℃(-50℃F). Kev ntsuam xyuas cuam tshuam rau A106 yog xaiv tau (Cov Lus Qhia Ntxiv S5/S6) thiab yuav tsum tau teev nyob rau hauv kev txiav txim thaum xav tau.
A106 Qib B muaj qhov sib npaug li cas?
Raws li A106 Qib B sib npaug hauv lwm lub tshuab, ASME qib yog SA-106 Qib B (tsim zoo ib yam rau tib tsab ntawv ASTM A106). Rau cross- siv, A106 Qib B feem ntau sib phim rau EN 10216-2 P265GH (ze tshaj los ntawm lub zog, kuj yog P235GH) rau seamless high-temperature raj, DIN 17175 St35.8, JIS G3454 STries 4}UNG, 37 thiab STPG 37 k03006 ua. Cov no yog cov qhab nia zoo sib xws rau kev yuav khoom hla kev siv, tsis nruj ASTM sib npaug, yog li lees paub nrog koj qhov kev pom zoo tsim.
