Astm A179 Cold Drawn Carbon Steel Yeeb Nkab
ASTM A179 yog tus qauv luam tawm los ntawm American Society for Materials and Testing (ASTM) uas qhia txog lub seamless txias-draw me steel yeeb nkab rau siv nyob rau hauv qis thiab nruab nrab siab boilers, tshav kub exchangers, thiab condensers.
ASTM A179 Seamless Boiler Tube
ASTM A179 yog cov yeeb nkab steeltus qauv tsim los ntawm American Society for Testing and Materials (ASTM) thiab feem ntau yog siv los tsim cov cuab yeej siv siab xws li chav turbines. Cov yeeb nkab steel no yog ua los ntawm cov pa roj carbon zoo lossis hlau alloy thiab yog tsim los ntawm cov txheej txheem kub dov lossis txias txheej txheem. Nws muaj qhov zoo ntawm lub zog siab, siab ua haujlwm siab, thiab corrosion kuj.
ASTM A179 steel kav yuav tsum tau mus los ntawm ntau yam txheej txheem thaum lub sij hawm tsim cov txheej txheem, xws li billet npaj, dov, straightening, tshav kub kev kho mob, pickling, soj ntsuam, thiab lwm yam. cev steel.
Hauv kev tsim cov khoom siv hluav taws xob siab, ASTM A179 seamless steel yeeb nkab ua lub luag haujlwm tseem ceeb heev. Vim nws lub zog siab, kev kub siab tsis kam thiab corrosion kuj, kev nyab xeeb thiab ruaj khov ntawm cov cuab yeej tuaj yeem ua kom ntseeg tau. Piv txwv li, nyob rau hauv chav turbines, hom steel yeeb nkab no tuaj yeem tiv taus qhov yaig thiab cuam tshuam ntawm qhov kub thiab txias siab, ua kom muaj kev ua haujlwm zoo ntawm cov khoom siv.
Hauv cov ntsiab lus, ASTM A179 yeeb nkab yog cov khoom siv hluav taws xob zoo, ua haujlwm siab steel yeeb nkab uas tau siv dav hauv kev tsim cov khoom siv hluav taws xob. Nws qhov zoo ntawm lub zog siab, kev kub siab ua haujlwm thiab corrosion kuj ua kom muaj kev ruaj ntseg thiab ruaj khov ntawm cov khoom siv.
