I-304l i-staing yentsimbi engenanto

I-304l i-pipe enentsimbi engenanto ngumbhobho wentsimbi ephathwe ngentsimbi engenasitayile, kwaye inkqubo yayo yonyango ikakhulu ibandakanya amanyathelo amabini: ukuthathwa kunye nokudlula. Le ndlela yonyango yenzelwe ukuphucula ukumelana nokunganyangeki kunye nokunganyangeki kwe-run ye-304l ehamba i-304l yentsimbi.

Okokuqala, ukhangela yinkqubo yokucoca ikhemikhali esebenzisa isisombululo se-acidic, idla ngokuba sisisombululo se-nitrogen-hydrofluric-hydrofluoric acid esinentsimbi engenasitayile. Injongo yeli nyathelo kukususa ungcoliseko kumphezulu wensimbi engenasimo, kubandakanya iidiphozithi zomphezulu, i-welding roper, kunye ne-chirling celing chibing, echaphazela ukunganyangeki kwe-corosion kunye nokuxhathisa i-corrosions yentsimbi engenasimo. Emva kokuzithandela, hlamba umphezulu wombhobho wentsimbi engenanto ngamanzi acocekileyo ukuqinisekisa ukuba umphezulu ucocekile kwaye ucocekile, wadala iimeko zefilimu elandelayo.

Okulandelayo, idrivetion yindlela yokucoca iikhemikhali ezisebenzisa isisombululo esingazisiyo kwi-304l i-pipe engenasitayile esihamba ngentsimbi, kodwa inokususa ngokufanelekileyo i-iron yokuthintela ifilimu yokukhusela. Unyango lokuphucula unyango lunokuziqhelanisa nefilimu yoqobo yokukhusela, ngaloo ndlela kukuphucula ukumelana nokuziphatha. Eli nyathelo alikhuseli kuphela kwaye lilungisa ifilimu yokukhusela, kodwa kwakhona idibanisa ifilimu yokukhusela phezu kombhobho wentsimbi ye-304l enesitayile esincinci, ukuphucula kakhulu ukumelana nokunganyangeki kwe-purrosion.

Ke ngoko, umbhobho wentsimbi ophumayo we-304l ongezantsi oye watshixwa kwaye ugqitywe ungathathwa njengombhobho wentsimbi ye-304l enesibindi, kunye nokuchasana nokunganyangeki kwe-rurosion kunye nokuchasana nokunganyangeki kwengqondo eneemfuno eziphezulu zokunganyangeki ezineemfuno eziphezulu zokunganyangeki ezineemfuno eziphezulu zokunganyangeki ezineemfuno eziphezulu zokunganyangeki ezineemfuno eziphezulu zokunganyangeki ezineemfuno eziphezulu zokunganyangeki ezineemfuno eziphezulu zokunganyangeki ezineemfuno eziphezulu zokunganyangeki ezineemfuno eziphezulu zokunganyangeki ezineemfuno eziphezulu zokunganyangeki ezineemfuno eziphezulu zokunganyangeki ezineemfuno eziphezulu zokunganyangeki ezineemfuno eziphezulu zokunganyangeki ezineemfuno eziphezulu zokunganyangeki ezineemfuno eziphezulu zokunganyangeki ezineemfuno eziphezulu zokunganyangeki ezineemfuno eziphezulu zokunganyangeki ezineemfuno eziphezulu zokunganyangeki. , njengelishishini lekhemikhali, ishishini lepetroleum, njl.
