Txhua qib yog silicon-tua los ntawm qhov yuav tsum tau ua - ib txoj kab yooj yim rau kev saib tsis tau ntawm daim ntawv qhia txog kev xeem zeb, tab sis kev coj ua deoxidation uas muab A106 nws cov qauv nplej thiab siab - qhov kub thiab txias.
Kub-Tiav vs. Txias-Drawn
A106yog seamless los ntawm cov ntsiab lus, tab sis tus qauv tso cai rau ob txoj hauv kev sib txawv tom qab tho, thiab qhov kev xaiv cuam tshuam qhov tseeb qhov tseeb ntau dua li nws cuam tshuam rau chemistry:
- Kub-ua tiav:Cov yeeb nkab yog dov thiab qhov loj me thaum tseem kub los ntawm lub tshuab tho, ces cua- txias. Qhov no yog tus qauv, qis dua - tus nqi txoj kev thiab npog qhov loj feem ntau ntawm A106 qhov ntau thiab tsawg.
- Txias- tau kos:Qhov kub- cov yeeb nkab tiav yog rub los ntawm qhov tuag ntawm chav tsev kub kom coj mus rau nruj OD thiab phab ntsa kam rau ua, ces normalized. Txias- kos A106 tus nqi ntau dua thiab feem ntau khiav ntawm lub sijhawm ua haujlwm ntev dua, tab sis nws yog txoj hauv kev los qhia thaum cov txheej txheem qis qis (precision dabtsi yog khoov, nruj- haum instrumentation tubing, me me- tho siab siab - lub siab sib dhos) tsis tuaj yeem nqus tau kub - ua tiav kev hloov pauv siab ntev.
Tsis yog txoj kev hloov cov qib chemistry lossis yam khoom siv yam tsawg kawg nkaus - A106 Qib B kub- tiav thiab A106 Qib B txias- kos tau raws li qhov yuav tsum tau muaj zog tib yam. Qhov sib txawv yog tag nrho nyob rau hauv nruj npaum li cas qhov kawg qhov ntev yog tuav, uas yog ib qho kev sib txawv uas tau ploj thaum "A106 Qib B" tau teev tseg yam tsis muaj qhov ua tiav.
Dimensional Tolerances
A106 ua raws li NPS/Schedule phab ntsa system nyob rau hauv ASME B36.10M es tsis yog ib tug ncaj qha OD callout. Key tolerance bands:
| Dimension | Kub-Tiav lawm | Txias-Tau |
|---|---|---|
| Sab nraud txoj kab uas hla | ± 0.75% (NPS 1/8–1½), nruj dua % raws li qhov loj me | ± 0.4% lossis zoo dua, qhov loj me -nyob ntawm |
| Phab ntsa Thickness | -12.5% ntawm nominal (tsis muaj ntxiv txwv) | -10% ntawm nominal (tsis muaj ntxiv txwv) |
| Kev ncaj | 0.2% ntawm tag nrho qhov ntev | Tighter, ib daim ntawv cog lus yuav khoom |
Phab ntsa thickness kam rau ua yog ib qho uas feem ntau miscalculated ntawm ib tug tsim tshuaj xyuas - ib tug Schedule 40 phab ntsa tsis tau lees paub los ntsuas Schedule 40 nyob txhua qhov chaw ntawm cov yeeb nkab. Kev ntsuas kev ntsuas siab uas siv cov phab ntsa nominal yam tsis siv qhov tso cai -muab daim duab rho tawm yog tsim los tiv thaiv phab ntsa thickness cov yeeb nkab tsis tas yuav xa.
Kev Ntsuas: Ntau dua li "Hydrostatic lossis tsis muaj dab tsi"
A106 muab lub zeb xaiv qhov kev lees paub, thiab qhov no yog qhov chaw cov neeg yuav khoom uas xav tias tsuas muaj ib txoj hauv kev tau txais qhov tsis txaus siab:
- Hydrostatic xeem- txhua qhov ntev siab- sim rau cov qauv kev ntxhov siab uas tau teev tseg hauv tus qauv.
- Nondestructive electric test (eddy tam sim no lossis ultrasonic)- lwm txoj rau hydrostatic, yog tias nws tau ntxiv los ntawm kev sim hydrostatic tsawg kawg ib qhov ntev, lossis raws li pom zoo.
Daim ntawv pov thawj zeb yuav tsum hais meej meej uas siv txoj kev thiab, thaum NDE raug xaiv, cov qauv kev lees paub thiab cov qauv siv tau siv. Kev yuav khoom uas tsuas yog hais tias "kuaj ib A106" yam tsis tau sau npe rau txoj kev nyiam tshaj tawm qhov kev txiav txim siab rau lub zeb - feem ntau zoo, tab sis tsim nyog lees paub thaum kawg daim ntawv thov (steam service, refinery piping) nws muaj nws tus kheej kev soj ntsuam kev cia siab nyob rau sab saum toj ntawm lub hauv paus ASTM.
Kev xa khoom thiab kev kho cua sov
Qib B thiab C yeeb nkab hla tej phab ntsa thicknesses tej zaum yuav xav tau normalizing, thiab kub - cov yeeb nkab tiav ua tiav saum toj kawg nkaus qhov kub thiab txias tuaj yeem ua tiav raws li - dov yam tsis muaj kev kho cua sov sib cais, muab cov khoom siv ua kom tiav. Qhov no yog ib qho lus nug cais los ntawm kev tshaj tawm-weld heat treatment thov tom qab kev tsim kho thaj chaw - A106 qhov kev xa khoom tswj hwm cov yeeb nkab raws li- xa khoom metallurgical xeev, tsis yog dab tsi tshwm sim rau nws tom qab tus fabricator txiav thiab welds nws mus rau hauv ib qho system.
Ib qho me me -Cov Ntaub Ntawv Npog Uas Qhia Txog Qhov Tsis Txaus Siab
A fabricator tau xaj A106 Qib B rau 2 "NPS, Teem caij 160 ntsuas cua header, qhia tsuas yog qib thiab lub sijhawm uas tsis muaj qhov ua tiav. Lub zeb xa khoom kub -cov yeeb nkab tiav - tag nrho ua raws li kev txiav txim raws li sau tseg - tab sis OD variation thoob plaws qhov ntau yog txaus tias ob peb qhov ntev ntawm kev sib txuas ua ntej yuav tsis muaj qhov loj me mus rau ib tug nruj zog band Re- xaj raws li txias- kos tau daws qhov teeb meem haum nrog tib qib, tib lub sij hawm, thiab tsis muaj kev hloov chemistry Qhov kev txiav txim tsis tau teev dab tsi tsis ncaj ncees lawm nws tsuas yog tsis tau teev ib qhov loj me ntawm daim ntawv thov tiag tiag.
Cov lus nug nquag nug (FAQ)
Q: Puas yog txias -kos A106 tau zoo dua li kub - tiav?
A: Tsis muaj zog lossis chemistry - ob qho tib si ua tau raws li qib kawm tib yam. Txias- kos tsuas yog tuav nruj dua qhov ntev ntawm tus nqi siab dua thiab lub sijhawm ua haujlwm ntev dua, yog li nws tsim nyog qhia tsuas yog thaum daim ntawv thov tiag tiag xav tau qhov tseeb.
Q: Puas yog A106 xav kom normalizing ntawm txhua qhov kev txiav txim?
A: Tsis yog. Kev ua kom zoo li qub hauv A106 yog khi rau qib thiab phab ntsa tuab qhov pib, thiab kub- cov yeeb nkab tiav ua tiav saum toj kawg nkaus qhov ntsuas kub tuaj yeem ua tau raws li cov kev xav tau yam tsis muaj cua sov sib cais- kho cov kauj ruam. Daim ntawv pov thawj zeb yuav tsum hais txog kev xa khoom ntawm ob txoj kev.
Q: Kev ntsuas tam sim no puas tuaj yeem hloov qhov ntsuas hydrostatic nkaus?
A: Tsis yog tag nrho ntawm nws tus kheej - A106 yuav tsum muaj qhov kev sim ntsuas hluav taws xob uas tsis muaj kev puas tsuaj ntxiv los ntawm kev sim hydrostatic tsawg kawg ib qhov ntev ntawm ib qho tshwj tsis yog pom zoo ntawm tus neeg yuav khoom thiab cov chaw tsim khoom. Daim ntawv pov thawj uas qhia tias tsuas yog NDE uas tsis muaj kev siv hydrostatic ntxiv yog tsim nyog rau cov lus nug ncaj qha rau lub zeb.
Q: Vim li cas kuv A106 Teem sijhawm 40 phab ntsa ntsuas nyias dua li tus lej nominal?
A: Vim tias tus qauv tso cai rau phab ntsa thickness khiav mus txog 12.5% hauv qab nominal ntawm kub- cov yeeb nkab tiav (10% ntawm txias- kos) uas tsis muaj ntxiv rau - sab txwv. Qhov no yog ib txwm, tus qauv- ua raws li kev ua siab ntev, tsis yog qhov tsis xws luag - tab sis nws yuav tsum tau suav rau hauv kev ntsuas kev ntsuas siab dua li qhov xav tau tam sim ntawd.
