1. Qhov txawv ntawm A106 thiab A53 yeeb nkab yog dab tsi?
A106yog rausiab -kubkev pabcuam thiab ib txwm muajseamless.
A53yog rau qhov dav dav, qis dua -kev pabcuam kub thiab tuaj yeem ua tauseamless(Hom S) los yogwelded(Type E, ERW).
2. Puas yog A106 yeeb nkab weldable?
Yog lawm, A106 yeeb nkab feem ntau suav hais tias yog weldable siv ntau txoj hauv kev xws li SMAW (Stick), GTAW (TIG), thiab GMAW (MIG). Txawm li cas los xij, preheat thiab post-weld heat treatment (PWHT) tej zaum yuav tsum tau, tshwj xeeb tshaj yog rau cov phab ntsa tuab thiab cov qib carbon siab dua (xws li Qib C), kom tsis txhob tawg.
3. Cov kev xeem twg yuav tsum tau ua los ntawm ASTM A106 tus qauv?
Tus txheej txheem mandates:
Tensile Test:Txhawm rau txheeb xyuas cov khoom siv kho tshuab (yield zog, tensile zog, elongation).
Flattening Test:Txhawm rau txheeb xyuas qhov ductility ntawm lub nplhaib qauv ntawm txhua qhov kawg ntawm cov yeeb nkab.
Hardness Test:(Yeem, tab sis feem ntau teev).
Tsis yog -Kev Ntsuas Hluav Taws Xob:(Yeem xaiv tau, zoo li qhov ntsuas tam sim no).
Hydrostatic Test:Txhua lub yeeb nkab yuav tsum tiv taus qhov kev sim siab uas ua rau muaj kev ntxhov siab sib npaug li 60% ntawm qhov tsawg kawg nkaus tawm los.
4. Qhov ntsuas hydrostatic siab rau A106 yeeb nkab yog dab tsi?
Kev ntsuas siab tsis yog tus nqi ruaj khov; nws yog xam raws li cov yeeb nkab phab ntsa thickness, txoj kab uas hla, thiab qib. Cov mis yog: P=2St / D, qhov twg P yog siab, S yog 60% ntawm min yield zog, t yog phab ntsa thickness, thiab D yog sab nraud txoj kab uas hla.
5. A106 yeeb nkab cim rau kev txheeb xyuas li cas?
Txhua yeeb nkab yog stenciled los yog tagged nrog:
Chaw tsim tshuaj paus lub npe los yog Trademark
ASTM A106 Daim Ntawv Pov Thawj
Qib (A, B, lossis C)
Kub naj npawb
Loj (NPS thiab Teem sijhawm)
Hydrostatic Test Siab los yog "HT"
Cov cim ntxiv yog tias tau teev tseg (piv txwv li, "NDE" rau tsis yog- kuaj kev puas tsuaj).
