1. Qhov kev pab cuam yam tsawg kawg nkaus ntawm A333 Qib 6 carbon steel yeeb nkab yog dab tsi?
Teb: A333 Qib 6 carbon steel yeeb nkab yog qhov qis -kub resistant carbon steel yeeb nkab, nrog rau qhov kev pab cuam yam tsawg kawg nkaus kub ntawm -45 degree, uas yog dav siv nyob rau hauv qis-kub pipelines xws li liquefied natural gas (LNG) thiab tub yees tshuab.
2. Dab tsi yog qhov txawv ntawm A106 Qib B thiab A333 Qib 6 carbon steel kav?
Teb: A106 Qib B yog qhov tsim nyog rau siab - qhov kev pabcuam kub (max 454℃), thaum A333 Qib 6 yog qhov tsim nyog rau qis - kev pabcuam kub (min -45℃). Cov tshuaj muaj pes tsawg leeg zoo sib xws, tab sis cov txheej txheem kev kho cua sov sib txawv, ua rau muaj qhov sib txawv ntawm qhov kub thiab txias.
3. Q355B carbon steel yeeb nkab puas tuaj yeem welded nrog A106 Qib B carbon steel yeeb nkab?
Teb: Yog. Q355B thiab A106 Qib B yog ob qho tib si carbon steel kav, nrog cov tshuaj muaj pes tsawg leeg zoo sib xws thiab weldability. Thaum vuam, xaiv cov khoom siv vuam tsim nyog (xws li E43 series electrodes) thiab tswj cov txheej txheem vuam kom ntseeg tau qhov vuam zoo.
4. Daim ntawv thov ntawm A53 Qib F carbon steel yeeb nkab yog dab tsi?
Teb: A53 Qib F yog seamless carbon steel yeeb nkab ua raws li ASTM A53 tus qauv, nrog cov ntsiab lus ntawm manganese ntau dua (1.00-1.35%) thiab tawv zoo dua qib B. Nws feem ntau yog siv rau siab - kub, nruab nrab-siab siab thauj khoom thiab cov khoom siv kho tshuab.
5. Lub zog tawm ntawm ST52-3 carbon steel yeeb nkab yog dab tsi?
Teb: ST52-3 yog carbon steel yeeb nkab ua raws li tus qauv DIN 17100, sib npaug rau Q355B hauv Suav teb. Nws qhov tsawg kawg nkaus tawm lub zog yog 355 MPa, tensile lub zog yog 490-630 MPa, nrog lub zog siab thiab zoo toughness, haum rau hnyav-load structural kav.
