Dej hiav txwv yog cov kua electrolyte uas muaj ntau cov ntsev thiab yaj qee qhov oxygen. Feem ntau cov khoom siv hlau yog electrochemically corroded hauv dej hiav txwv. Cov chloride ion cov ntsiab lus hauv dej hiav txwv yog loj heev, uas ua rau tus nqi corrosion nce. Tib lub sijhawm, cov tam sim no thiab cov xuab zeb me me tsim cov kev ntxhov siab reciprocating qis zaus thiab cuam tshuam rau cov khoom siv hlau. Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho sai ntawm kev txhim kho thiab kev siv dej hiav txwv, kev tsim kho loj ntawm cov dej hiav txwv nuclear fais fab projects thiab kev txhawb nqa ntawm kev lag luam desalination dej hiav txwv, daim ntawv thov ntawm seawater-resistant npauj npaim li qub tau dhau los ua ntau dua thiab ntau dua. Txhawm rau qhov kawg no, NSEN tau tsim ib tug seawater-resistant npauj npaim li qub uas yog tsim rau kev lag luam marine, nuclear fais fab dej hiav txwv txias thiab lwm yam lag luam.

Cov npauj npaim li qub uas tiv taus dej hiav txwv, txhawm rau hloov kho rau qhov xeb ntawm chloride ions hauv dej hiav txwv, lub cev valve, npauj npaim phaj thiab lwm yam khoom siv feem ntau yog ua los ntawm duplex stainless hlau, titanium alloy thiab txhuas bronze. Qhov tsis zoo tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov dej hiav txwv. Piv txwv li, titanium alloy npauj npaim valve muaj kev ua tau zoo heev hauv txhua yam, tab sis cov thev naus laus zis smelting ntawm titanium thiab titanium alloy yog qhov nyuaj, thiab txoj kev tau txais titanium alloy castings yog qhov nyuaj, nyuaj rau ua, thiab tus nqi kim heev. Yog tias lub npauj npaim valve yog ua los ntawm duplex stainless hlau, nws tuaj yeem tiv taus qhov xeb ntawm chloride ions, tab sis qhov tsis kam tiv taus kev yaig tsis zoo. Lub qhov dej ntws thiab qhov chaw sib khi tau yooj yim puas tsuaj los ntawm kev yaig, ua rau qhov chaw sib khi ntawm lub npauj npaim valve xau.

NSEN muab kev daws teeb meem zoo rau peb cov neeg siv khoom-Roj Hmab Tiv Thaiv Dej Hiav Txwv, cov koob no tsim nrog ob chav offset tsim thiab nrog cov khoom siv sealing mos xws li EPDM lossis cov khoom PTFE.
