1. Cov tshuaj muaj pes tsawg leeg ntawm A106 Qib B seamless carbon steel yeeb nkab yog dab tsi?
A106 Qib B yog cov pa roj carbon steel seamless yeeb nkab qib rau siab -kev pabcuam kub. Nws cov tshuaj muaj pes tsawg leeg (feem ntau) yog: Carbon (C) ≤ 0.30%, Manganese (Mn) 0.29-1.06%, Phosphorus (P) ≤ 0.035%, Sulfur (S) ≤ 0.035%, Silicon (Si) ≤ 0.10%, Fe ). Nws tsis muaj lub siab xav alloying cov ntsiab lus, uas ua kom zoo ductility thiab weldability thaum ua tau raws li qhov yuav tsum tau ua ntawm qhov kub thiab txias.
2. Qhov kev pabcuam siab tshaj plaws ntawm A106 Qib B seamless yeeb nkab yog dab tsi, thiab nws cov kev siv tseem ceeb yog dab tsi?
Qhov siab tshaj plaws kev pabcuam kub ntawm A106 Qib B seamless yeeb nkab yog 454 ° C (850 ° F). Nws yog tsuas yog siv nyob rau hauv cov chaw tsim hluav taws xob, refineries, thiab tshuaj nroj tsuag rau kev thauj cov siab - kub thiab nruab nrab - cov kua dej siab, xws li chav dej, dej, thiab roj teeb. Nws kuj tau siv dav hauv cov kav dej dav dav vim nws cov nqi -kev ua tau zoo thiab kev ua tau zoo.
3.Dab tsi yog qhov txawv ntawm API 5L Qib B thiab A106 Qib B seamless kav?
Cov kev sib txawv tseem ceeb nyob hauv lawv cov qauv tsim, cov ntawv thov scenarios, thiab cov khoom siv tshuab: ① Standard: API 5L yog tsim los ntawm American Petroleum Institute rau roj thiab roj tsheb thauj mus los, thaum A106 yog tsim los ntawm American Society for Testing and Materials (ASTM) rau siab -cov kav dej kub. ② Mechanical zog: API 5L Qib B muaj qhov tsawg kawg nkaus yield zog ntawm 241 MPa thiab lub zog tensile yam tsawg kawg nkaus ntawm 414 MPa; A106 Qib B muaj qhov tsawg kawg nkaus lub zog ntawm 248 MPa thiab lub zog tensile yam tsawg kawg nkaus ntawm 414 MPa. ③ Daim Ntawv Thov: API 5L Qib B feem ntau yog siv rau ntev - cov roj thiab cov kav xa hluav taws xob (sab qaum teb thiab sab ntug dej hiav txwv), thaum A106 Qib B yog siv rau siab -kub dej sib kis hauv cov khoom siv.
4. A106 Qib C seamless yeeb nkab puas tuaj yeem siv rau hauv qhov chaw qis -kub? Dab tsi yog nws qhov qis - qhov kub thiab txias qhov yuav tsum tau muaj?
A106 Qib C tuaj yeem siv rau hauv qhov chaw qis - qhov kub thiab txias, tab sis nws qhov qis - qhov kub thiab txias qhov kev ua tau zoo yog qis dua li qib B. Tus qauv xav kom A106 Qib C yuav tsum tau kuaj xyuas qhov cuam tshuam ntawm -10 ° C (14 ° F), thiab qhov tsawg kawg nkaus qhov nruab nrab ntawm lub zog (KV) yuav tsum yog 27 J rau txhua qhov teeb tsa. Nws yog qhov tsim nyog rau qhov tsis tshua muaj - qhov ntsuas kub ntawm cov dej xa mus rau qhov chaw uas qhov kub tsis poob qis dua -10 ° C, xws li cov dej kub qis thiab lub teeb hydrocarbon tsheb thauj mus los hauv thaj chaw txias nrog lub caij ntuj no me me.
5. Dab tsi yog daim ntawv thov ntawm API 5L X42 seamless yeeb nkab, thiab nws cov khoom tseem ceeb yog dab tsi?
API 5L X42 yog ib qho nruab nrab - lub zog raj steel qib, dav siv nyob rau hauv onshore thiab offshore roj thiab roj xa cov kav dej, nrog rau cov kav dej hauv nroog. Nws cov yam ntxwv tseem ceeb yog: qhov tsawg kawg nkaus lub zog ntawm 290 MPa, lub zog tensile yam tsawg kawg nkaus ntawm 414 MPa, elongation ≥ 21%, thiab cuam tshuam lub zog ≥ 40 J (kuaj ntsuas kub -20 ° C rau feem ntau daim ntawv thov). Nws muaj qhov zoo toughness thiab weldability, uas tuaj yeem hloov mus rau qhov kev hloov pauv kev ntxhov siab tshwm sim los ntawm cov kav dej tso thiab cov kua dej siab.
