Qhov txawv ntawmAPI 5L Qib BthiabASTM A106 Qib Bfeem ntau yog lawvxav thovthiabkev txwv kev tsim khoom. Txawm hais tias lawv yog cov tshuaj lom neeg thiab mechanically zoo sib xws, lawv tau tswj hwm los ntawm cov qauv sib txawv rau qhov chaw sib txawv.
Scope thiab Lub Hom Phiaj
ASTM A106 Qib B:Tsim los rausiab - kub, siab - kev pabcuam siab. Nws yog yuav luag tsuas yog siv "sab hauv cov nroj tsuag" rau cov txheej txheem piping hauv refineries, fais fab nroj tsuag, thiab cov chaw tshuaj uas muaj cua sov yog qhov tseem ceeb.
API 5L Qib B:Tsim los rauthauj roj, roj, thiab dej. Nws yog siv rau "kab yeeb nkab"- mais ntawm cov kav dej uas txav cov kua dej los ntawm lub qhov dej mus rau lub chaw ua dej lossis thoob plaws lub tebchaws.
Manufacturing (Qhov txawv loj tshaj)
ASTM A106 Qib B:Yuav tsum yogSeamless. Tsis muaj qhov zoo li "Welded A106."
API 5L Qib B:Ua tauSeamless los yog Welded(ERW, LSAW, SSAW). Vim tias cov kav dej feem ntau xav tau cov kab uas loj heev (dhau 24 ntiv tes), welded API 5L yeeb nkab yog qhov tsis tshua muaj neeg.
Chemical Composition (Silicon Cov ntsiab lus)
A106 B:Yuav tsum muaj aSilicon cov ntsiab lus tsawg kawg yog 0.10%. Silicon ua tus deoxidizer (ua rau nws "Killed Steel"), uas txhim kho cov yeeb nkab kev ua tau zoo nyob rau hauv siab - qhov kub thiab txias.
API 5L IB:Tsis muaj qhov tsawg kawg nkaus Silicon yuav tsum tau rau PSL 1 (txawm hais tias nws yog feem ntau tam sim no).
Khoom Specification Levels (PSL)
ASTM A106 B Cov Lus Qhia:Nws tsuas muaj ib theem ntawm kev ua tau zoo.
API 5L IB:Muab faib ua ob theem:
PSL 1:Standard zoo rau kev siv.
PSL 2:Ntau qhov kev xav tau nruj dua rau cov tshuaj muaj pes tsawg leeg, tawv (kev sim cuam tshuam), thiab tsis yog -kev sim ua kom puas (NDT). PSL 2 feem ntau siv nyob rau hauv ntug dej hiav txwv lossis "qaub" (H2S) ib puag ncig.

Daim Ntawv Qhia Kev Xaiv: API 5L Qib B vs ASTM A106 Qib B
| Daim ntawv thov Scenario | Pom zoo Qib | Xaiv Logic | Manufacturing Requirements |
| Refinery & Chemical Process Piping | ASTM A106 B | Siab -kub tsis kam.A106 B mandates Silicon cov ntsiab lus ( Ntau dua lossis sib npaug rau Greater dua lossis sib npaug 0.10%), muab kev nkag siab zoo tshaj plaws nyob rau hauv siab - qhov chaw sov (txog 425℃). |
Seamless (SMLS) nkaus xwb |
| Ntev -Ntaus Roj, Roj, & Dej Pipelines | API 5L IB | Kev lag luam mus ntev.API 5L suav nrog cov kev xaiv welded (ERW / LSAW). Rau cov kab loj loj, cov kav dej welded yog tus nqi ntau dua - zoo dua seamless. | Seamless los yog Welded |
| Siab -Npaum Chav & Boiler Kab | ASTM A106 B | Kev nyab xeeb tseem ceeb.A106 B yog "Fullly Tua Steel." Cov kav dej seamless no yog tus qauv thoob ntiaj teb rau siab -heat / siab-siab tshuab tshuab. | Seamless (SMLS) nkaus xwb |
| Lub Nroog Gas Distribution Networks | API 5L IB | Weldability tseem ceeb.API 5L nruj me ntsis tswj cov Carbon Equivalent (CE), ua rau nws zoo tagnrho rau loj - nplai teb thiab nroog vuam siv. | Feem ntau ERW (welded) |
| General Structure / Piling | API 5L B (PSL1) | Tus nqi tseem ceeb.Rau cov qauv kev txhawb nqa lossis qis- thauj cov kua dej siab, API 5L PSL1 yog qib qis tshaj plaws muaj. | Seamless los yog Welded |
| Offshore / Severe Environments | API 5L B (PSL2) | Toughness qhov tseem ceeb.PSL2 txoj cai Charpy V-Kev ntsuas qhov cuam tshuam los tiv thaiv kev puas tsuaj hauv qhov hnyav lossis sub- xoom. | Seamless los yog LSAW (PSL2) |

FAQ
Cov khoom siv dab tsi yog A106 GRB?
A106 GRB yog ib tug neeg Asmeskas -tus qauv seamless carbon steel yeeb nkab khoom tsim los rau siab - qhov kub thiab txias kev pab cuam; raug xaiv raws li ASTM A106 Qib B, nws tau dav siv nyob rau hauv siab - kub thiab siab - cov kua xa hluav taws xob xa hluav taws xob thoob plaws hauv kev lag luam xws li roj av, tshuaj, thiab hluav taws xob fais fab.
Qhov txawv ntawm API 5L Qib B PSL1 thiab PSL2 yog dab tsi?
API 5L Qib B PSL1 thiab PSL2 sib txawv feem ntau hauv kev ua tau zoo thiab kev tshuaj xyuas: PSL1 yog tus txheej txheem zoo nrog cov tshuaj lom neeg muaj pes tsawg leeg thiab cov cuab yeej cuab yeej tshwj xeeb, thiab tsis tso cai rau kev sim cuam tshuam lossis tsis yog - kuaj kev puas tsuaj. PSL2 yog tus qauv siab dua nrog kev tswj hwm nruj ntawm cov tshuaj muaj pes tsawg leeg (piv txwv li, qis P thiab S cov ntsiab lus) thiab cov khoom siv kho tshuab, thiabyuav tsum tau Charpy V-notch (CVN) cuam tshuam kev sim thiab 100% tsis yog-kev kuaj kev puas tsuaj (NDT), ua rau nws haum rau kev pabcuam hnyav dua.
