Indlela yokuphatha imibhobho yentsimbi engenamthungo eyi-16mn emva kokubola?

I-16mn i-seamless steel pipe yinto ebalulekileyo kwimibhobho yentsimbi engenamthungo. Kwizicelo ezisebenzayo, ngenxa yeendawo ezahlukeneyo kunye nezinto ezisetyenzisiweyo, umphumo wesicelo jikelele we-16mn umbhobho wensimbi ongenamthungo uhluke. Kudla ngokubakho iimeko zokubola kwemibhobho yentsimbi engenamthungo eyi-16mn. Indlela yokujongana ne-corrosion yingxaki enzima ejongene nayo wonke umntu. Loluphi unyango lokudleka kwemibhobho yentsimbi engenamthungo eyi-16mn? Intshayelelo kwiifektri zemibhobho yentsimbi engenamthungo: Ngokubanzi, unyango lwenziwa ngolu hlobo lulandelayo:

Intsimbi ye-16mn yombhobho wentsimbi engenamthungo idibana neoksijini esibhakabhakeni, yenze ifilimu ye-oxide phezu komhlaba. Nangona kunjalo, i-iron oxide eyenziwe kwimibhobho ye-carbon steel eqhelekileyo iyaqhubeka i-oxidize, ibangela ukubola kwande kwaye kubangele ukubunjwa kweepores. Ngale ndlela, umbhobho olungileyo we-16mn ongenamthungo uya konakala. Sinokusebenzisa ipeyinti okanye isinyithi esichasayo kwi-oxidation. Ngokomzekelo, i-zinc, i-nickel, kunye ne-chromium zi-electroplated ukukhusela umphezulu we-carbon steel, kodwa njengoko kulindelekile, oku kugcinwa kukuphela kwefilimu yokulondoloza. Ukucinga ukuba umaleko wokulondoloza wonakaliswe, intsimbi iya kuqala ukubola. Ukuxhatshazwa kwe-corrosion yensimbi engenasici kuxhomekeke kwi-chromium, eyinxalenye yokwakheka kwentsimbi. Xa i-chromium idityaniswe nentsimbi, iya kutshintsha uhlobo lwe-oksidi kumphezulu ukuze ifane naleyo yentsimbi ecocekileyo yechromium. Le chromium etyebileyo i-oksidi ibambelele ngokuqinileyo igcina umphezulu kwaye inqanda i-oxidation eyongezelelweyo.

I-16mn ipayipi yensimbi engenamthungo luhlobo olubalulekileyo lwensimbi, kwaye ingqwalasela ekhethekileyo kufuneka ihlawulwe kwinkqubo yonyango ye-corrosion eqhelekileyo. Unyango olungafanelekanga lwe-16mn yombhobho wentsimbi engenamthungo emva kokubola kunokukhokelela kwiingxaki ngokulula!
