Dab tsi yog sa106c seamless steel yeeb nkab?
Sa106cyog ib qho tshwj xeeb rau seamless cov pa roj hlau yeeb nkab hauv qab Astm A106 tus qauv. Qhov "C" txhais tau cov qhab nia, uas muaj cov txiaj ntsig carbon ntau dua li nws cov counterparts, A106 qib A thiab qib B.
Nws yog tshwj xeeb tsim rauhigh - kev pab kubThiab yog dav siv hauv cov nroj tsuag fais fab, kev ua kom zoo, thiab Petrochemical cov chaw rau thauj cov chav, dej, roj, thiab roj.
Cov yam ntxwv tseem ceeb & Cov txiaj ntsig zoo
Seamless kev tsim kho:Cov yeeb nkab tsim los ntawm tho ib lub ntsej muag ntawm cov hlau, tsim cov yeeb nkab uas tsis muaj welds nyob hauv nws txoj kev ncig. Qhov no ua rau nws muaj zog dua thiab txhim khu kev qha rau kev siab rau high- qhov kev siv hluav taws xob piv rau welded kav.
High - kub kev ua tau zoo:The primary advantage of the A106 specification is its ability to maintain strength at elevated temperatures (up to ~750℃F / 400℃).
Lub zog: muaj zog:Qib C muaj lub zog tshaj plaws thiab tawm lub zog tshaj plaws ntawm peb qib kawm A106, ua rau nws haum rau qhov kev xav tau lub siab.
Zoo machinability thiab weldability:Raws li cov pa roj carbon, nws yog qhov yooj yim rau lub tshuab thiab weld nrog cov txheej txheem ua ntej, txawm hais tias ua ntej weld cua sov vim muaj cov ntsiab lus muaj roj carbon ntau dua.
Tshuaj lom neeg tshuaj lom neeg (ASTM A106 Txuj Ci)
Cov tshuaj lom neeg muaj pes tsawg leeg yog qhov sib txawv tseem ceeb ntawm qib kawm. Sa106C muaj cov ntsiab lus ntau cov roj carbon ntau dua rau lub zog.
| Lub ntsiab | Muaj pes tsawg leeg (%) |
|---|---|
| Carbon (c) | 0.35 Max |
| Manganese (mn) | 1.00 max |
| Phosphorus (p) | 0.035 Max |
| Sulphur (s) | 0.035 Max |
| Silicon (si) | 0.10 min |
Nco tseg: Cov ntsiab lus tsawg kawg nkaus yog qhov tseem ceeb rau kev muab cov oxidation tiv thaiv ntawm qhov kub.
Cov Khoom Siv Neeg Kho Tshuab (ASTM A106 Txuj Ci)
Cov kev ntseeg no yog rau ib txwm muaj lossis qub -}- temperarent mob, uas yog tus qauv kev kho cua sov.
| Ntiag tug | Tus nqi |
|---|---|
| Tensile lub zog, min | 70,000 psi (485 mpa) |
| Paib muaj zog, min | 40,000 psi (275 mpa) |
| Elongation | Saib cov qauv rau cov nqi tsawg kawg nkaus raws li phab ntsa tuab |
Cov Kev Siv Cov Ntawv Siv
Sa106C Seamless kav yog cov haujlwm ntawm ntau qhov kev lag luam tseem ceeb:
Lub zog tiam:Cov kab hauv chav tseem ceeb, cov kab nuv ntses, thiab siab - kub piping hauv cov roj pob zeb thiab hluav taws xob.
Roj & Roj Tshuab:Cov txheej txheem piping rau cov roj nyoos, hydrocarbons, thiab cov roj av ntxiv nyob rau hauv kev kub siab thiab kub.
Petrochemical Nroj Tsuag:Hloov chaw cov kua dej thiab catalysts.
Tub tshib Tube:Rau siab - how boiler tshuab.
Kev Ua:Txhua daim ntawv thov xav tau lub zog, siab - qhov siab will rau chav lossis dej kub.
Kev sib piv nrog lwm cov qib thiab cov qauv
Nws yog qhov pab tau kom nkag siab li cas ntawm 56c cuam tshuam nrog rau lwm cov khoom siv cov yeeb nkab uas zoo ib yam.
1. Hauv Astm A106:
| Teem nqi | Tensile lub zog (min) | Yield zog (min) | Qhov tseem ceeb sib txawv |
|---|---|---|---|
| A106 A | 48,000 psi (330 MPa) | 30,000 PSI (205 MPA) | Qis tshaj plaws lub zog, siv rau txo siab. |
| A106 B | 60,000 psi (415 MPA) | 35,000 psi (240 MPA) | Cov qhab nia siv feem ntau rau cov siab siab - Temp kev pab. |
| A106 C | 70,000 psi (485 mpa) | 40,000 psi (275 mpa) | Lub zog siab tshaj plaws, rau cov haujlwm xav tau tshaj plaws. |
2. Astm A53 vs. Astm A106:
ASTM A53:A General - lub hom phiaj txheem rau cov txheej txheem thiab qis - cov kua siab ua kua conveye. Nws tuaj yeem yog seamless lossis welded (ERW). Thaum qib A53 B muaj cov khoom siv zoo sib xws rau A106 qib B,A106 yog qhov kev xaiv uas nyiam tshaj plaws rau qhov siab- kev pabcuam kubVim tias nws txoj kev kho kom sov thiab cov txheej txheem rho tawm cov kws kho teeb meem tswj hwm rau qhov siab - temp kev ua tau zoo.
3. Astm A333 vs. ASTM A106:
ASTM A333:NpogTsawg - kev pab kub(piv txwv li, nqis rau -50℃F / -45 degree). A106 yog rau qhov kub thiab txias; lawv siv rau kev mob ib puag ncig.
Cov kev txiav txim tseem ceeb rau kev siv
Kev Kho Cua Sov:Sa106C kav yog feem ntau muab rau hauvzoo li caslossisQub thiab Temperedmob. Cov kev kho cua sov no kho tau cov qauv grain, txhim kho lub zog thiab tawv.
Weldability:Vim nws cov ntsiab lus muaj roj carbon ntau dua, SA106C muaj qhov muaj txiaj ntsig zoo dua (CE) tus nqi dua qib B. Qhov no txhais tau tias nws muaj kev cuam tshuam ntau rauhardening nyob rau hauv lub tshav kub -} cuam tshuam cheeb tsam (Haz)thaum vuam. Tsim nyog vuam cov txheej txheem, suav nrogUa ntej - cua sov thiab tswj kev cuam tshuam qhov kub siab, feem ntau yuav tsum ua kom tiv thaiv kev tawg.
Corrosion Kuj:Raws li cov pa roj carbon hlau, nws tsis yog xeb - tsis kam. Rau kev xeb ib puag ncig, nws yuav tsum tau siv nrog cov txheej txheem tiv thaiv, cov pob, lossis ua ke nrog corrosion inhibitors.
