1. Q: Dab tsi tsis yog -kev kuaj kev puas tsuaj (NDT) txoj kev siv los ua kom zoo?
A:Cov txheej txheem NDT feem ntau suav nrog Kev Ntsuas Ultrasonic (UT) txhawm rau txheeb xyuas qhov tsis zoo ntawm sab hauv thiab subsurface, Eddy Current Testing (ET) rau saum npoo thiab ze ntawm - deg tsis xws luag, Hydrostatic Testing los xyuas kom meej lub zog siab, thiab Dye Penetrant Inspection (DPI) rau saum npoo tawg.
2. Q: Dab tsi yog "Hydrostatic Testing," thiab nws puas yuav tsum tau ua?
A:Kev ntsuas hydrostatic suav nrog kev sau cov yeeb nkab nrog dej thiab nias nws mus rau qib siab dua li nws qhov ntsuas kev ua haujlwm siab los xyuas nws qhov kev ncaj ncees thiab xau- nruj. Nws yog qhov yuav tsum tau ua ntawm feem ntau cov qauv yeeb nkab.
3. Q: Cov pa roj carbon seamless yeeb nkab puas tuaj yeem corroded? Qhov no txo qis li cas?
A:Yog, carbon steel yog raug rau corrosion. Txoj kev txo qis suav nrog kev siv cov txheej txheem sab hauv / sab nraud (xws li epoxy, FBE), galvanizing, lossis siv cov txheej txheem tiv thaiv cathodic thaum cov yeeb nkab faus lossis submerged.
4. Q: Dab tsi yog qhov tseem ceeb ntawm "S," "R," thiab "T" hauv cov ntaub ntawv xeem?
A:Hauv cov qauv zoo li EN 10204, a2.2 Daim Ntawv Qhia Txog Cov Khoom Sivyog ib daim ntawv pov thawj muab los ntawm cov chaw tsim khoom. Hom "S" qhia txog daim ntawv pov thawj ntawm kev ua raws cai yam tsis muaj cov txiaj ntsig kev xeem tshwj xeeb, "R" qhia cov txiaj ntsig ntawm cov zeb, thiab "T" qhia cov kev ntsuas tshwj xeeb tau ua los ntawm cov qauv ntawm cov khoom muab lawv tus kheej.
5. Q: Dab tsi yog "Quenching thiab Tempering" (Q & T) kev kho cua sov?
A:Q&T yog ob - cov txheej txheem kev kho cua sov siv rau cov kav dej siab dua - qib. Quenching (ceev txias) tsim ib qho nyuaj heev tab sis nkig qauv. Tempering (reheating kom qis dua) ces txo qhov brittleness thiab nce toughness, ua rau muaj kev sib xyaw ua ke zoo heev ntawm lub zog thiab ductility.
