ASTM A53 Qib B (kuj tseem hu uaASTM A 53 Qib Blos yogA53 GrB) tseem yog ib qho ntawm cov yeeb nkab hlau carbon uas paub zoo tshaj plaws thoob ntiaj teb. Nws yog siv dav hauv kev xa dej, roj thiab roj av, cov kav dej ua vaj tse, cov tshuab kho tshuab, thiab cov kav dej boiler.
Tiam sis thaum cov haujlwm thoob ntiaj teb sib xyaw cov qauv, cov neeg yuav khoom yeej yuav nug tias:
"Dab tsi yog qhovASTM A53cov khoom sib npaug hauv EN, DIN lossis JIS?
Phau ntawv qhia no nthuav dav qhov kev sib piv, qhia txog cov qib hlau sib npaug, piav qhia txog kev sim sib txawv, thiab pab koj ntsuas kev sib pauv thaum nrhiav khoom.ASTM A53 yeeb nkab hlau, cov yeeb nkab seamless, lossis cov khoom hloov pauv.
Nkag Siab Txog ASTM A53 Qib B: Cov Yam Ntxwv Tseem Ceeb
ASTM A53/A53M npogcov yeeb nkab hlau tsis muaj seamless (Hom S)thiabERW vuam yeeb nkab(Hom E)rau lub hom phiaj dav dav.
✔ ASTM A53 Qib B lub zog qib yog nruab nrab-siab, feem ntau siv rau hauv kev thauj mus los kua thiab kev ua haujlwm siab.
Cov Tshuaj Lom Zem (ASTM A53 Gr B):
Cov pa roj carbon ≤ 0.30%
Manganese ≤ 1.20%
Phosphorus ≤ 0.05%
Sulfur ≤ 0.045%
Cov Khoom Siv Kho Tshuab:
Lub zog tensile ≥415 MPa
Lub zog tawm los ≥240 MPa
Kev ntev ≥20%
ASTM A53 GrB Cov Khoom Sib Npaug hauv EN, DIN & JIS
Cov qib no sib xws nrog ASTM A53 cov ntaub ntawv sib npaug hauv cov nqe lus ntawm lub zog, cov pa roj carbon thiab cov khoom elongation.
Vim Li Cas LawvMuaj Peev Xwm Sib Piv Tau?
EN P235GH→ Cov qoob loo: ~ 235 MPa, Tensile: 360–500 MPa - yuav luag zoo ib yam li ASTM A53 Qib B.
JIS STPG410→ Cov pa roj carbon zoo sib xws thiab elongation - zoo tagnrho rau cov ntawv thov uas xav tau kev tiv taus siab thiab weldability.
Yog li ntawd, cov ntaub ntawv no feem ntau tuaj yeem suav hais tias yog ASTM A53 GrB, tshwj xeeb tshaj yog nyob rau hauv boiler, cov qauv thiab cov kav dej siab.
ASTM A53 vs ASTM A106 vs API 5L — Kev Tsis Meej Pem ntawm Cov Neeg Yuav Khoom
Muaj ntau tus engineers thoob ntiaj teb tsis yog tsuas yog nrhiav"A53 GrB sib npaug"tab sis kuj nug tias:
✔ "ASTM A106 puas sib npaug rau ASTM A53?"
✔ "Puas yog API 5L sib npaug rau A53 GrB?"
Lus teb: tsis yog raws nraim.
Yog li ntawdle ASTM A106 Qibde B thiabAPI 5L Qib B feem ntau raug hais tawm, lawv yoglwm txoj kev xaiv, tsis yog qhov sib npaug nruj.
Qhov Txawv ntawm Kev Tsim Khoom Tseem Ceeb
Txawm tias cov khoom siv ASTM A53 sib npaug sib xws, cov cai tshuaj xyuas sib txawv:
ASTM A53 Qib B
Kev sim hydrostatic
NDT rau cov seams vuam
Kev sim khoov/ua kom tiaj tus
Npog ob qho tib siERW thiab seamless
Qhov no yog vim li cas koj thiaj li yuav pom cov lus hais txog kev nrhiav khoom xws li ASTM A53 ERW steel yeeb nkab thaum teev cov qauv welded.
EN P235GH / P235TR
Cov kev cai ntxiv rau kev ntsuam xyuas kev cuam tshuam
Cov ntaub ntawv ntxiv txog kev sib txuas ntawm cov hlau
DIN 1629
Kev kam rau siab dua rau cov kav dej tsis muaj qhov sib txuas
JIS G3454
Kev ua tau zoo rau kev siv boiler thiab cov kav dej siab
Yuav Ua Li Cas Thiaj Paub Tseeb Txog Kev Sib Npaug Ntawm Cov Qauv?
✔ Piv cov nqi kho tshuab thiab tshuaj lom neeg (± 5% kev kam rau siab lees txais)
✔ Thov daim ntawv pov thawj MTC lossis EN/DIN/JIS uas muaj hom ntawv no
✔ Kev tshuaj xyuas los ntawm lwm tus neeg (xws li SGS / BV / TÜV) rau kev lees paub tus qauv hla tus qauv
Cov txheej txheem no txo qhov kev pheej hmoo thaum xaivASTM A53 cov khoom sib npaugrau cov haujlwm thoob ntiaj teb.
