Siab -Quality Seamless and Welded Pipes for Marine and Industrial Applications
Copper nickel kavyog tsim los ntawm ib tug alloy ntawm tooj liab thiab npib tsib xee, nrog ntxiv dag zog rau cov ntsiab lus xws li manganese thiab hlau. Txawm tias muaj cov ntsiab lus tooj liab,tooj liab nickel kavmuaj xim nyiaj. Cov alloys no tau ua pov thawj tias yogtiv taus dej hiav txwv, dej brine, organic compounds, ntsev, thiab diluted uas tsis yog -oxidizing acids.
Vim muaj kev tiv thaiv siab rau cov kab mob marine xws li barnacles,tooj liab npib tsib xee feem ntau yog siv nyob rau hauv seawater piping systems thiab roj piping systems.
