Uyini umehluko phakathi kuka-304 no-316 we-stainless steel tube?

Amashubhu ensimbi engagqwali asetshenziswa kakhulu ezimbonini ezahlukahlukene ngenxa yokuqina kwawo, ukumelana nokugqwala, namandla aphezulu. Izinhlobo ezimbili ezivamile zamashubhu ensimbi engagqwali zingama-304 no-316. Nakuba zombili zenziwe ngensimbi engagqwali, kunomehluko omkhulu phakathi kwazo. Nakhu ukuhlukaniswa komehluko omkhulu phakathi kwamashubhu ensimbi engagqwali angama-304 nangama-316.

 

Ukwakheka

Umehluko omkhulu phakathi kwamashubhu ensimbi engagqwali angama-304 nangama-316 usekubunjweni kwawo. Zombili zenziwe ngensimbi, i-chromium, ne-nickel, kodwa insimbi engagqwali engu-316 iqukethe i-molybdenum eyengeziwe. Lokhu okuqukethwe okwengeziwe kwe-molybdenum kunikeza insimbi engagqwali engu-316 ukumelana nokugqwala okuphakeme uma kuqhathaniswa no-304.

 

Ukumelana Nokugqwala

Insimbi engagqwali engu-304 yaziwa ngokumelana nokugqwala okuhle, okuyenza ilungele ukusetshenziswa kwangaphakathi nangaphandle. Kodwa-ke, ayimelani nokugqwala njengensimbi engagqwali engu-316. Okuqukethwe kwe-molybdenum yensimbi engagqwali engu-316 kuyenza imelane kakhulu nokugqwala kwe-chloride, okusho ukuthi ifaneleka kangcono indawo yasolwandle nezinye izindawo ezigqwalile.

 

Izinhlelo zokusebenza

Ngenxa yokumelana nokugqwala okuhle, insimbi engagqwali engu-304 ivame ukusetshenziswa ezinhlelweni ezifana nemishini yasekhishini, imishini yokucubungula ukudla, nezinye izinhlelo zokusebenza zokwakha. Ngakolunye uhlangothi, insimbi engagqwali engu-316 ikhethwa ezindaweni ezibucayi kakhulu njengokucutshungulwa kwamakhemikhali, ukusetshenziswa olwandle, nezifakelo zokuhlinzwa ngenxa yokumelana nokugqwala okuphakeme.

 

Izindleko

I-304 insimbi engagqwali ngokuvamile ithengeka kakhulu kune-316 yensimbi engagqwali ngenxa yokwakheka kwayo okulula nokusetshenziswa kwayo okusabalele. Uma ufuna inketho engabizi kakhulu esanikeza ukumelana nokugqwala okuhle, insimbi engagqwali engu-304 ingaba inketho engcono. Kodwa-ke, uma udinga izinga eliphakeme kakhulu lokumelana nokugqwala kohlelo oluthile, insimbi engagqwali engu-316 ingase ifanele izindleko ezengeziwe.

 

Kafushane, umehluko omkhulu phakathi kwamashubhu ensimbi engagqwali angama-304 nangama-316 usekubunjweni kwawo, ukumelana nokugqwala, nasekusetshenzisweni kwawo. Insimbi engagqwali engu-304 inikeza ukumelana nokugqwala okuhle futhi iyabiza, kuyilapho insimbi engagqwali engu-316 inokumelana nokugqwala okuphakeme ngenxa yokuqukethwe kwayo okwengeziwe kwe-molybdenum. Lapho ukhetha phakathi kwakho kokubili, cabangela izidingo ezithile zohlelo lwakho lokusebenza kanye nezinga lokumelana nokugqwala okudingayo.
