Q1: Qhov txawv ntawm Yield Strength thiab Tensile Strength yog dab tsi?
A1: Yield zogyog qhov kev nyuaj siab uas cov khoom pib deform plastically.Tensile zog(los yog lub zog kawg) yog qhov siab tshaj plaws uas nws tuaj yeem tiv taus ua ntej tawg -10.
Q2: Lub hom phiaj ntawm kev sim flattening ntawm cov yeeb nkab seamless yog dab tsi?
A2:Kev kuaj flattening yog ib qho kev kuaj xyuas zoo los ntsuas qhov ductility ntawm cov hlau thiab lub suab ntawm cov yeeb nkab phab ntsa. Cov yeeb nkab yog flattened mus rau qhov sib txawv ntawm daim hlau tsis tawg -3.
Q3: Charpy V-Notch (CVN) cuam tshuam li cas?
A3:Nws yog ib qho kev ntsuam xyuas uas ntsuas lub zog ntawm cov khoom siv absorbs thaum tawg ntawm qhov kub thiab txias. Nws yog ib qho tseem ceeb rau kev txiav txim siab cov khoom siv hluav taws xob - mus rau - qhov hloov pauv kub, tshwj xeeb tshaj yog rau cov kev pabcuam kub qis (ASTM A333) -5-6.
Q4: Kev kuaj Hydrostatic yog dab tsi?
A4:Nws yog ib qho kev sim siab qhov twg cov yeeb nkab tau ntim nrog dej thiab nias rau ib theem tshwj xeeb kom paub tseeb tias cov xau nruj thiab lub zog ntawm cov khoom siv yeeb nkab tsis ua rau deformation mus tas li -3-7.
Q5: Dab tsi yog "Hardness" hais txog cov pa roj carbon steel, thiab vim li cas nws tseem ceeb rau kev pabcuam qaub (H2S)?
A5:Hardness yog qhov tsis kam rau indentation. Hauv kev pabcuam qaub (H2S ib puag ncig), NACE MR0175 txwv qhov siab tshaj plaws hardness txwv los tiv thaiv Sulfide Stress Cracking (SSC) -9.
