1. Q: Dab tsi ua rau AISI 1018 steel ib qho kev xaiv rau txhua yam tubing?
A:AISI 1018 yog ib qho me me, qis - carbon steel (0.15-0.20% C) nrog weldability zoo heev thiab machinability zoo. Nws tuaj yeem ua tau yooj yim txias kos thiab fabricated. Nws yog siv rau cov ntawv thov uas xav tau qhov ntev thiab qhov chaw du, xws li shafts, pins, thiab rollers.
2. Q: Rau siab - lub zog boiler daim ntawv thov, qib twg yog feem ntau siv?
A:ASTM A192 yog qib tshwj xeeb rau siab - siab boiler raj. Nws yog ib qho qis- carbon steel (seamless) paub txog nws txoj kev ntseeg siab nyob rau hauv siab - kub thiab siab - ib puag ncig siab hauv boiler systems.
3. Q: Dab tsi yog qhov tseem ceeb ntawm ASTM A179 tubing?
A:ASTM A179 yog seamless low - carbon steel tube tshwj xeeb tsim los rau kev sib pauv cua sov thiab kev pabcuam condenser. Nws cov nplaim du thiab thermal conductivity ua rau nws zoo tagnrho rau kev hloov cov cua sov hauv cov ntawv thov no.
4. Q: Cov ntsiab lus carbon ntawm AISI 1045 steel cuam tshuam li cas rau nws siv hauv cov kav dej thiab lub tog raj kheej?
A:AISI 1045 yog ib qho nruab nrab - carbon steel (0.43-0.50% C) muab lub zog thiab hardness ntau dua 1018. Thaum siv rau hydraulic thooj voos kheej kheej lossis cov khoom siv tshuab precision, nws tuaj yeem raug kho cua sov (quenched thiab tempered) kom ua tiav lub zog ntau dua thiab hnav tsis kam, tab sis nws cov weldability yog qhov nyuaj dua.
5. Q: Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm kev siv galvanized ASTM A53 yeeb nkab?
A:Qhov kub-dip galvanizing (zinc txheej) siv rau A53 yeeb nkab muab kev tiv thaiv corrosion zoo heev, ua rau nws zoo tagnrho rau kev siv sab nraum zoov, cov kav dej, thiab cov laj kab uas tiv thaiv xeb yog qhov tseem ceeb.
