Nyob rau hauv cov neeg xav tau ib puag ncig ntawm cov tubrog nkoj, fais fab, thiab kev lag luam ua lag luam, kev xaiv ntawm cov ntawv xa khoom yog qhov tseem ceeb. Ntawm cov cav saum toj kawg nkaus rau corrosion - tiv taus tubing yog tooj liab alloys, teev nyob rau hauv cov qauv zoo li ASTM B466 rau seamless yeeb nkab yeeb nkab thiab raj. Tus qauv no yog npog ob peb tus copper - nickel (c71500, txhua qhov kev muab cov khoom sib luag tshwj xeeb ntawm cov kev pabcuam tshwj xeeb. ASTM B466 tau teeb tsa cov cai rau seamless kav thiab cov leeg ua los ntawm cov alloys, ua kom zoo nkauj, thiab cov kws kho mob {13} {tiv thaiv cov ntawv thov.
Vim li cas thiaj xaiv ASTM B466 tooj liab - cov leeg npib tsib xee?
Dej hiav txwv corrosion:Cov alloys ib daim ntawv tiv thaiv, cov yeeb yaj kiab adherent oxide uas ruaj khov rau pitting, thiab kev ntxhov siab corrosion tawg.
Zoo biofouling Kuj:Tooj liab ionse rached los ntawm nplaim insibit thiab kev loj hlob ntawm cov kab mob marine uas zoo li barnacles thiab qwj txoj kev txij nkawm thiab txhim kho kev ua hluav taws xob.
Zoo Bricability:ASTM B466 cov hlab muaj peev xwm tau yooj yim khoov, thiab tsoo siv cov txheej txheem txheej txheem, tso cai rau kev teeb tsa yooj yim thiab cov kab ntsig.
Pov thawj ntev:Cov txheej txheem pov tseg los ntawm cov ntaub ntawv no muaj cov ntaub ntawv tso cai ua haujlwm tshaj 40 xyoo hauv ib puag ncig marine, muab lub neej tsawg- lub neej.
