NAB C95800 Pob Valves

Lus piav qhia luv luv:

Nickel Aluminium Bronze Ball Valves ntawm kev tiv thaiv corrosion zoo heev, ua qhov tsim nyog thiab pheej yig dua hloov mus rau monel rau ntau daim ntawv thov dej hiav txwv. Nickel Aluminium Bronze pob li qub yog tsim los ntawm npib tsib xee thiab ferromanganese. Nrog zoo corrosion kuj, Nickel Aluminium bronze pob li qub ua raws li cov khoom tseem ceeb rau marine propellers, twj, li qub thiab underwater fasteners, tau dav siv nyob rau hauv seawater desalination thiab petrochemical kev lag luam.

Vim li cas thiaj siv NAB Aluminium Pob Valves?

Qhov zoo ntawm NAB pob li qub yog qhov tseem ceeb. Cov hom kev lag luam no tshwj xeeb tshaj yog tsim rau cov dej hiav txwv, qhov twg cov khoom siv corrosion, tshwj xeeb tshaj yog lawv cov chloride pitting, zoo heev. Cov cuab yeej siv rau kev tsim cov castings ntawm qhov zoo ib yam yog paub zoo, thiab tsis muaj qhov xav tau me ntsis rau qhov kev sim uas tsis muaj kev puas tsuaj uas yuav tsum tau muaj rau 6Mo, duplex, thiab super duplex steels.
Mechanically, lub pob valve no yog piv rau lwm yam nrov corrosion-resistant alloys, tab sis nyob rau hauv thiaj li yuav coj kom zoo dua ntawm cov khoom no, tshwj xeeb tshaj yog cov kev ntsuas siab-kub yuav tsum tau siv. Zoo heev occlusal thiab hnav cov khoom pab kom lub neej ntev thiab kev ua tau zoo ntawm NAB pob li qub.
Cov kev txwv ntawm hom tes ua valve yog tias nws yuav tsum tsis txhob siv nyob rau hauv ib puag ncig sulphide thiab nws cov kev txwv ntws yuav tsum tau txiav txim siab. Kev sib tw cam khwb cia hlau thiab steel li qub xav tau qee hom kev tiv thaiv kom sib tw thiab txawm tias qhov zoo thiab ua haujlwm ntawm qhov kev tiv thaiv no txiav txim siab lub neej ntev. Stainless hlau li qub yog raug rau cov crevice corrosion thiab pitting nyob rau hauv seawater, thiab 6Mo, duplex thiab super duplex stainless hlau li qub yog txwv rau qhov kub ntawm 20 ℃ thiab siab tshaj chlorine ntsiab lus nyob rau hauv seawater kev pab cuam. Tus nqi ntawm cov kab txawv ntau dua alloys dhau los ua qhov tseem ceeb thiab yuav tsum tau muaj kev ncaj ncees tshwj xeeb.
