1.Dab tsi yog txheej txheej feem ntau siv rau A53 Qib B yeeb nkab rau sab nraum zoov lossis corrosive ib puag ncig?
Teb:Cov txheej txheem tiv thaiv feem ntau yog Galvanization, uas cuam tshuam nrog kev siv cov zinc txheej. Cov txheej txheem no tsim ASTM A53 Qib B Galvanized Steel Yeeb Nkab, uas muaj kev tiv thaiv zoo rau atmospheric corrosion.
2. Puas yog A53 Qib B haum rau siab -kev pabcuam kub?
Teb:A53 Qib B tuaj yeem siv rau qee qhov nruab nrab - kev pabcuam kub (xws li chav dej), tab sis nws yogtsis cais raws li cov hlau alloy rau siab -kub kev pab cuam. Rau kev ua haujlwm siab -kev siv kub (xws li, hauv cov chaw tsim hluav taws xob), cov ntaub ntawv zoo li ASTM A106 Qib B, uas muaj kev tswj hwm nruj dua ntawm cov tshuaj muaj pes tsawg leeg, yog qhov nyiam.
3. Lo lus "Schedule" txhais li cas hauv cov ntsiab lus ntawm A53 yeeb nkab (piv txwv li, Teem caij 40)?
Teb:"Schedule" (abbreviated as SCH) yog ib tug txheej txheem ntawm cov zauv uas qhia tusphab ntsa thicknessntawm cov yeeb nkab rau ib qho loj me me. Lub sij hawm ntau dua txhais tau tias yog phab ntsa tuab thiab siab dua qhov ntsuas. Piv txwv li, 2-nti NPS Schedule 80 yeeb nkab muaj phab ntsa tuab dua li 2-nti NPS Schedule 40 yeeb nkab.
4. A53 Qib B yeeb nkab puas tuaj yeem welded yooj yim?
Teb:Yog, A53 Qib B yog cov pa roj carbon steel nrog zoo weldability. Nws tuaj yeem welded siv txhua txoj hauv kev xws li Shielded Hlau Arc Vuam (SMAW), Gas Hlau Arc Vuam (GMAW), thiab lwm yam. Yuav tsum ua raws li cov txheej txheem vuam kom raug.
5. Dab tsi yog qhov tseem ceeb ntawm cov tshuaj muaj pes tsawg leeg txwv rau A53 Qib B uas cuam tshuam rau nws cov weldability thiab lub zog?
Teb:Ib qho kev txwv tseem ceeb yog cov ntsiab lus Carbon, uas feem ntau yog qhov siab tshaj ntawm 0.30%. Cov pa roj carbon qib no muab qhov sib npaug zoo ntawm lub zog thiab ductility, ua rau cov hlau tawv thiab yooj yim weldable yam tsis dhau nkig.
