Hnyav Phab Ntsa Seamless Steel Tube ASTM A519
Vim li cas thiaj xaiv Hnyav Phab Ntsa Seamless Steel Tube ASTM A519?
Kev siv tau ntawm ASTM A519 tuab-walled seamless yeeb nkab hauv thaj chaw ntawm cov tshuab feem ntau yog los ntawm nws qhov siab - precision dimensional control, zoo heev mechanical zog, thiab optimized material design, uas zoo kawg nkaus haum cov kev cai nruj ntawm cov cuab yeej siv rau cov khoom siv.
1. Muab piv nrog ASTM A106, ASTM A519 tus qauv tuaj yeem ua tiav qhov kev ua haujlwm sab nraud nyob rau hauv ± 0.05mm los ntawm cov txheej txheem txias txias lossis cua sov txheej txheem, thiab qee qhov kev qhia tshwj xeeb txawm mus txog qib "tsis kam ua siab ntev" (piv txwv li, sab nraud txoj kab uas hla 6-630mm, phab ntsa thickness 1-50mm). Qhov no precision ua kom nruj ntawm txhua yam sib dhos, tshwj xeeb tshaj yog rau cov khoom uas yuav tsum tau muaj qhov sib txuam siab, xws li hydraulic thooj voos kheej kheej thiab cov kabmob rings.
2. ASTM A513 txhua yam yeeb nkab tsis muaj zog li A519 vim nws siv ERW nrog welds; thaum lub phab ntsa tuab ntawm A519 tuab-walled seamless yeeb nkab txhim kho nws lub peev xwm los tiv thaiv kev kub siab thiab tshem tawm cov ntsiab lus tsis muaj zog ntawm cov welds, ua rau kev ntxhov siab ntawm cov yeeb nkab ntau dua thaum nws raug siab los yog torsional loads, txo qhov kev pheej hmoo ntawm deformation.
3. ASTM A519 yeeb nkab, tshwj xeeb tshaj yog cov qib qis carbon (xws li 1020), yooj yim rau tshuab, txiav, laum, thiab ua tiav.

Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg ntawm cov phab ntsa hnyav seamless steel raj raws li ASTM A519 specification tuaj yeem sib txawv raws li qib tshwj xeeb. Txawm li cas los xij, lub
Cov tshuaj muaj pes tsawg leeg yuav suav nrog cov ntsiab lus xws li carbon, manganese, phosphorus, sulfur, silicon, chromium, molybdenum, npib tsib xee, thiab lwm yam. Qhov tseeb muaj pes tsawg leeg yuav nyob ntawm qib ntawm cov hlau.
Hauv qab no yog ib lub rooj qhia txog cov tshuaj muaj pes tsawg leeg ntawm ASTM A519 hnyav phab ntsa seamless steel hlab:
| Element | Cov pa roj carbon | Manganese | Phosphorus | Sulfur | Silicon | Chromium | Molybdenum | Nickel | Lwm tus |
| Kev sib xyaw ua ke | 0.15-0.25% | 0.30-0.60% | 0.035% max | 0.040% max | 0.15-0.35% | 0.80-1.10% | 0.15-0.25% | 0.40-0.70% | - |
Mechanical Properties
Cov khoom siv kho tshuab xav tau rau cov phab ntsa hnyav seamless steel raj hauv qab ASTM A519 nyob ntawm seb qib tshwj xeeb thiab txoj kab uas hla ntawm lub raj. Qee cov khoom siv kho tshuab muaj xws li lub zog tensile, lub zog tawm los, elongation, thiab hardness.
Cov lus hauv qab no qhia txog cov khoom siv kho tshuab ntawm ASTM A519 hnyav phab ntsa seamless steel hlab:
| Khoom | Tensile zog | Yield zog | Elongation | Hardness |
| Tus nqi | 580-760 MPa | 450 MPa min | 15% min | 80 HRB max |
Cov qhab nia xaiv tau
Txawm tias1020, 1021, 1022, 1025, thiab1026yog cov qib uas siv ntau tshaj plaws rauhnyav phab ntsa seamless steel raj, muaj lwm cov qhab nia uas yuav raug txiav txim siab raws li cov cai tshwj xeeb ntawm daim ntawv thov:
ASTM A106 1: Qhov no yog tus qauv specification rau seamless carbon steel yeeb nkab rau siab - kub kev pab cuam. Nws yog lwm txoj hauv kev zoo thaum daim ntawv thov cuam tshuam nrog siab - qhov kub thiab txias.
ASTM A333 Cov khoom lag luam: Tsim los rau qis- qhov kub thiab txias, cov raj no muaj kev cuam tshuam zoo dua ntawm qhov kub thiab txias.
ASTM A 213: Ib qho kev qhia tshwj xeeb rau seamless ferritic thiab austenitic alloy steel hlab, tshwj xeeb tshaj yog siv nyob rau hauv tshav kub exchangers thiab boilers.
ASTM A335 Cov Lus Qhia Tshwj Xeeb: Npog seamless ferritic alloy-steel kav rau siab- qhov kub thiab txias, haum rau kev siv fais fab nroj tsuag.
TIAB SA 17175: Tus qauv German rau seamless steel raj siv nyob rau hauv boilers, tshav kub exchangers, thiab siab hlab ntsha, muab siab dua tiv thaiv tshav kub.
Ntim
Thaum cov kav dej tau dhau tag nrho cov kev tshuaj xyuas thiab kev sim, lawv npaj txhij rau ntim. Lawv feem ntau yog ntim rau hauv bales qhwv hauv yas. Cov kav dej tuaj yeem muab ntim thiab npaj rau kev xa khoom raws li cov neeg siv khoom xav tau, kom ntseeg tau tias cov kav dej muaj kev tiv thaiv thaum lub sijhawm thauj mus los thiab tiv thaiv qhov chaw puas.
