Ipayipi Lensimbi Engagqwali engu-304L Yemigqa Yamakhemikhali: Ukushibilika Nokugqwala

Isingeniso

Ipayipi lensimbi engagqwali elingu-304L lemigqa yamakhemikhaliisetshenziswa ezinhlelweni zokudlulisa amakhemikhali okugqwala okuphansi kuya kokuphakathi, amapayipi okucubungula, izintambo zikagesi, imishini yokwelapha amanzi, ukuxhumeka kwamathangi okugcina izinto, izinhlelo zokuhlanza kanye nezintambo zoketshezi olujwayelekile lwezimboni. I-304L inguqulo yensimbi engagqwali engu-304 enekhabhoni ephansi, okwenza ifaneleke ezinhlelweni zamapayipi ahlanganisiwe lapho ukushintshwa okuhle kanye nengozi encishisiwe yokugqwala okuphakathi kwe-granular ngemva kokushintshwa kubalulekile.

Ekusetshenzisweni kwemigqa yamakhemikhali, ipayipi lensimbi engagqwali elingu-304L livame ukukhethwa lapho i-medium ingenaso i-asidi ephezulu, ingathwali i-chloride enamandla futhi ingadingi ukumelana nokugqwala okuphezulu kwe-alloy. Inikeza ukusebenza okuhle kokwenziwa, indawo ehlanzekile, ukutholakala okubanzi kanye nokuhlinzekwa okungabizi kakhulu. Kodwa-ke, abathengi kufanele babuyekeze ngokucophelela ukuhlushwa kwamakhemikhali, izinga lokushisa, izinga le-chloride, i-pH, ingcindezi, indlela yokuhlanza kanye nezidingo zokushisela ngaphambi kokukhetha izinto zensimbi engagqwali ezingu-304L kunezinto zensimbi engagqwali ezingu-316L, 321, 904L, insimbi engagqwali noma i-nickel alloy ezimbili.

Izimo Zokusetshenziswa Kwepayipi Lensimbi Engagqwali engu-304L Emigqeni Yamakhemikhali

Ipayipi lensimbi engagqwali elingu-304L livame ukusetshenziswa ezitshalweni zamakhemikhali nasezindaweni zezimboni lapho uketshezi luhambisana nensimbi engagqwali ye-austenitic nalapho kudingeka khona ukushisela. Akuyona ipayipi elimelana namakhemikhali elijwayelekile, ngakho-ke ukusetshenziswa kufanele kuhlolwe ngaphambi kokukhetha.
