1. Dab tsi yog qhov txawv ntawm ASTM A53 thiab ASTM A106 kav?
ASTM A53yog tus qauv rau ob qho tib si seamless thiab welded kav, feem ntau yog siv rau kev siv tshuab thiab siab nyob ze - qhov kub thiab txias.ASTM A106 1yog tshwj xeeb rau cov kav dej seamless siv nyob rau hauv siab -cov kev pabcuam kub, xws li hauv cov refineries thiab fais fab nroj tsuag. A106 muaj cov kev cai tshuaj nruj dua thiab ib txwm seamless -2-10.
2. Qhov "X" hauv API 5L yeeb nkab qib zoo li X42 lossis X80 txhais li cas?
Hauv API 5L specification rau kab yeeb nkab, "X" yog ua raws li qhov tsawg kawg nkaus yield zog hauv kilopounds ib square inch (ksi). Piv txwv li, X42 muaj qhov tsawg kawg nkaus lub zog ntawm 42 ksi, thaum X80 muaj qhov tsawg kawg nkaus yield zog ntawm 80 ksi (kwv yees li 555 MPa) -1-2.
3. Dab tsi yog cov ntawv thov rau ASTM A500 yeeb nkab?
ASTM A500 yog tus qauv rau txias- ua welded thiab seamless carbon steel structural tubing. Nws yog siv rau hauv kev tsim kho, txuas hniav, vaj tse, thiab kev siv cov txheej txheem dav dav uas cov yeeb nkab ua haujlwm ua tus tswv cuab (qib A, B, C, lossis D) -6.
4. Cov khoom siv twg yog feem ntau siv rau boiler raj nyob rau hauv siab?
ASTM A192 Cov Lus Qhia Tshwj Xeebyog tus qauv rau seamless carbon steel boiler raj rau siab - kev pabcuam siab. Lwm qib sib txawv rau nruab nrab - carbon steel boilers thiab superheaters yog ASTM A210 -2.
5. Dab tsi yog cov qhab nia rau cov roj thiab cov kav dej raws li API 5CT?
Feem ntau API 5CT qib suav nrogJ55, K55, N80, L80, thiab P110. Cov qib no yog siv rau cov casing thiab tubing hauv kev lag luam roj thiab roj, nrog rau qib sib txawv ntawm lub zog thiab kev tiv thaiv corrosion -2.
