ASTM A106 Qib B yog dab tsi?
ASTM A106 yog American Society for Testing and Materials specification for seamless carbon steel pipe for high -kub kev pab cuam, raug xaiv A106/A106M. Qib B yog qib siv dav tshaj plaws ntawm cov lus qhia tshwj xeeb, npog cov pa roj carbon seamless nrog lub zog qis kawg nkaus ntawm 240 MPa thiab lub zog tensile yam tsawg kawg nkaus ntawm 415 MPa. Nws tsuas yog tsim los ntawm seamless yeeb nkab, los ntawm kub xov los yog txias kos duab, thiab yog lub neej ntawd cov khoom siv rau ntau lub zog, refining thiab tshuaj txheej txheem piping systems.
Cov khoom siv yog cov pa roj carbon steel uas ua rau nruj kev txwv kev txwv. Ib qho tshwj xeeb ntawm A106 yog qhov yuav tsum tau muaj qhov tsawg kawg nkaus ntawm silicon cov ntsiab lus, uas qhia tau hais tias tag nrho cov hlau tua thiab ua rau lub suab, weldable yeeb nkab nrog ruaj khov siab - qhov kub thiab txias.
Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg ntawm A106 Qib B yog tswj nyob rau hauv cov kev txwv hauv qab no, uas sib npaug lub zog, weldability thiab tsis kam mus rau siab - qhov kub thiab txias kev pab cuam.
| Element | Txwv,% |
|---|---|
| Cov pa roj carbon C | 0.30 max |
| Manganese Mn | 0.29 - 1.06 |
| Phosphorus P | 0.025 max |
| Sulfur S | 0.025 max |
| Silicon Si | 0.10 min |
| Chromium Cr | 0.40 max |
| Nickel Nim | 0.40 max |
| Tooj Cu | 0.40 max |
| Molybdenum Cov | 0.15 max |
| Vanadium V | 0.08 max |
Cov kev txwv seem ntawm chromium, npib tsib xee, tooj liab, molybdenum thiab vanadium xyuas kom meej tias cov khoom tseem yog cov pa roj carbon monoxide tiag tiag yam tsis muaj kev sib koom ua ke, uas ua rau cov txheej txheem vuam yooj yim thiab kwv yees.
Mechanical Properties
| Khoom | Kev xav tau |
|---|---|
| Tensile zog, min | 415 MPa rau |
| Yield zog, min | 240 MPa |
| Elongation | Ib lub rooj hauv ASTM A106, raws li phab ntsa tuab thiab ntsuas qhov ntev |
Cov nqi no tau teev nyob rau ntawm chav tsev kub; nyob rau ntawm qhov kev pab cuam siab kub qhov tso cai rau kev ntxhov siab yog muab los ntawm cov lej kev ntxhov siab, uas suav nrog kev txo qis ntawm lub zog nrog qhov kub thiab txias.
Qhov ntau thiab tsawg ntawm kev tsim khoom
A106 Qib B seamless yeeb nkab yog muaj nyob rau hauv ntau qhov loj, feem ntau ntawm 21.3 hli mus txog 762 hli txheej kab, nrog phab ntsa thickness ntawm 2.0 hli mus txog 140 hli. Qhov loj seamless loj yog tsim los ntawm kub xov, thaum me me diameters thiab nruj tolerances yog tsim los ntawm txias txias.
Cov yeeb nkab feem ntau yog muab nrog cov xaus los yog beveled xaus rau vuam, thiab nyob rau hauv ib qho random, ob chav random los yog tsau ntev. Kev ntsuam xyuas hydrostatic yog ua tiav ntawm txhua cov yeeb nkab tshwj tsis yog qhov tsis yog -kev ntsuas hluav taws xob puas tsuaj tau pom zoo, thiab kev sim tensile thiab flattening lossis dabtsi yog khoov yog ua raws li qhov tshwj xeeb.
Tej kev siv
Kev tsim hluav taws xob: boiler thiab superheater piping, chav kab thiab feedwater systems.
Petrochemical thiab refining: txheej txheem piping, furnace transfer lines thiab utility systems handle high -kub fluids.
Kev tsim kho thiab kev lag luam cov nroj tsuag: siab - kub thiab siab - siab carbon steel piping qhov twg seamless tsim yuav tsum tau.
Qib A, B thiab C thiab cov khoom sib piv
A106 txhais tau peb qib. Qib A muaj cov pa roj carbon tsawg tshaj plaws thiab lub zog, Qib B yog tus qauv kev xaiv rau kev ua haujlwm siab - qhov kub thiab txias, thiab Qib C muaj lub zog tensile siab tshaj plaws ntawm peb.
Hauv kev xyaum suav, A106 Qib B feem ntau ua rau GB / T 8163 qib 20, thiab Qib A mus rau qib 10. Cov kev sib piv no yooj yim rau kev siv, tab sis cov kev cai tswj xyuas kev yuav khoom, kuaj thiab tsim qauv yuav tsum yog tus qauv siv tau raws li kev cog lus, vim tias kev kho cua sov, qhov ntsuas qhov ntsuas thiab kev kam rau siab tuaj yeem sib txawv.
Xaiv thiab soj ntsuam cov ntsiab lus
Xaiv Qib B tshwj tsis yog tias tus qauv tsim kub lossis siab yuav tsum muaj lub zog siab dua ntawm Qib C, thiab paub meej tias yuav tsum tau ua kom tiav cov phab ntsa tuab ua ntej xaj.
Ua pov thawj ntawm daim ntawv lees paub tias daim ntawv pov thawj zeb kuaj pom cov naj npawb cua sov, tshuaj ntsuam xyuas thiab tensile cov txiaj ntsig, thiab tias qhov kev sim hydrostatic thiab ib qho kev pom zoo uas tsis yog -kev kuaj xyuas puas tau ua tiav.
Thaum lub sij hawm vuam, ua raws li cov txheej txheem tsim nyog rau carbon steel yeeb nkab thiab paub meej tias cov hlau muab tub lim sib tw rau cov khoom siv lub zog.
