1. Q: Dab tsi yog "Duplex" stainless hlau yeeb nkab? Muab piv txwv qib.
A: Duplex stainless hlau muaj ib qho sib xyaw microstructure ntawm austenite thiab ferrite, muab lub zog siab thiab zoo heev tiv thaiv kev ntxhov siab corrosion tawg. Qib ib txwm yog UNS S31803/S32205 (22% Cr, 5% Ni, 3% Mo, 0.15% N).
2. Q: ASTM A519 yog dab tsi?
A: ASTM A519 npog seamless carbon thiab hlau alloy hlau mechanical tubing, siv rau machining qhov chaw, hydraulic thooj voos kheej kheej, thiab cov khoom siv uas yuav tsum tau muaj qhov ntev thiab zoo mechanical zog.
3. Q: Dab tsi yog "DOM" raj, thiab nws puas seamless?
A: DOM (Drawn Over Mandrel) tubing yog aweldedcov khoom uas ces txias kos. Nws tsis yog seamless, tab sis nws muaj qhov zoo ntawm qhov tseeb thiab qhov chaw tiav, feem ntau sib tw nrog seamless mechanical tubing.
4. Q: Dab tsi yog "Hollow Forging" txheej txheem rau seamless kav?
A: Nws yog cov txheej txheem forging tshwj xeeb uas ib qho khoom siv tau pierced thiab tom qab ntawd forged rau ntawm lub mandrel los tsim loj - txoj kab uas hla, hnyav - phab ntsa seamless kav (xws li, rau nuclear lossis siab - kev siv lub nkoj siab).
5. Q: Dab tsi yog "Extrusion" txheej txheem rau seamless kav?
A: Nyob rau hauv extrusion, ib tug rhuab billet yog yuam los ntawm ib tug tuag nrog ib tug mandrel los tsim cov yeeb nkab zoo li. Nws feem ntau yog siv rau nyuaj- rau- cov ntaub ntawv ua haujlwm xws li stainless hlau, npib tsib xee alloys, thiab tsis yog - ferrous hlau.
