A199 Cold Drawn Seamless Alloy Steel Yeeb Nkab
ASME SA 199 Round Pipes
A199 yog ib hom carbon structural steel hauv Asmeskas tus qauv. Nws yog tsuas yog siv nyob rau hauv cov xwm txheej uas yuav tsum tau muaj zog tsis siab. Nws lub zog tawm los thiab lub zog tensile ntau yog 250 ~ 400MPa thiab 400 ~ 620MPa feem. Vim nws muaj ntau tshaj 0.2% alloying ntsiab
A199 tshav kub exchanger raj muaj superior tag nrho txhua yam khoom. Cov yeeb nkab steel no tuaj yeem tsim los ntawm ob txheej txheem: seamless txias kos duab lossis kub dov, qhov kev xaiv tshwj xeeb yog nyob ntawm qhov xav tau tiag tiag. Kev siv seamless txias txheej txheem pab txhim kho qhov tseeb qhov tseeb thiab qhov zoo ntawm cov kav dej.
A199 alloy steel yeeb nkabfeem ntau yog ua los ntawm cov hlau tsis tshua muaj carbon steel, uas muab nws zoo plasticity thiab toughness thiab yooj yim rau txheej txheem. Txawm li cas los xij, nws qhov kev tiv thaiv corrosion yog txwv, thiab rau qhov tshwj xeeb ib puag ncig uas xav tau kev tiv thaiv corrosion ntau dua, lwm yam khoom siv hlau yuav xav tau.
A199 alloy structural steel yeeb nkab yog dav siv nyob rau hauv pipelines rau thauj cov kua, xws li roj thiab natural gas, vim nws zoo corrosion kuj thiab kua sealing zog.
