Q1: Peb cov qauv ASTM feem ntau yog dab tsi rau seamless carbon steel kav siv nyob rau hauv siab -cov kev pabcuam kub?
A1:Peb cov qauv feem ntau yogASTM A106 1(Seamless Carbon Steel Pipe rau High-Tsev Kev Pabcuam),ASTM A53(Hom S), thiabAPI 5L(rau kab kav) -2-5.
Q2: Dab tsi yog qhov txawv ntawm daim ntawv thov ntawm ASTM A53 thiab ASTM A106?
A2:ASTM A53 feem ntau yog siv rau kev siv tshuab thiab kev siv siab thiab tuaj yeem welded lossis seamless. ASTM A106 tshwj xeeb yog tsim los rau siab - cov kev pabcuam kub (xws li boilers thiab superheaters) thiab nruj nreem seamless, nrog rau cov kev cai nruj dua (xws li, cov ntsiab lus silicon) -2-5.
Q3: Tus qauv ASTM twg yog siv cov pa roj carbon steel kav rau qis-kev pabcuam kub?
A3: ASTM A333 / ASME SA333 Cov Lus Qhiayog tus qauv rau seamless thiab welded carbon steel kav npaj rau qis- kev pabcuam kub (xws li, Gr. 6 feem ntau txog -50℃F/-45℃) -5-9.
Q4: "Qib B" txhais li cas hauv cov qauv xws li ASTM A106 lossis A53?
A4:"Qib" qhia cov khoom siv kho tshuab. Qib B muaj lub zog tensile siab dua thiab cov txiaj ntsig tau zoo dua piv rau Qib A. Piv txwv li, A106 Qib B yuav tsum muaj lub zog tensile yam tsawg kawg nkaus ntawm 60,000 psi (415 MPa) -2-5.
Q5: Qhov txawv ntawm API 5L PSL1 thiab PSL2 yog dab tsi?
A5:PSL2 (Product Specification Level 2) muaj qhov yuav tsum tau nruj dua li PSL1, suav nrog kev sim yuav tsum tau ua, qhov siab tshaj plaws carbon sib npaug (CE) txwv rau weldability zoo dua, thiab nruj dua rau cov tshuaj muaj pes tsawg leeg -5-9.
