904L super austenitic insimbi engagqwali amapayipi ashiselwe ezimbonini

I-904L iyinsimbi engagqwali eyi-super-austenitic enokumelana nokugqwala okuphezulu kakhulu, ikakhulukazi ezindaweni eziqukethe ama-ion e-chloride. Le nto iqukethe i-nickel ephezulu kanye nokuqukethwe kwe-molybdenum, kanye nenani elilinganiselwe lethusi, elinikeza ukumelana nokugqwala okuhle kakhulu ezindaweni ezine-acidic, alkaline, ne-saline.904L insimbi engagqwali isetshenziswa kabanzi embonini yamakhemikhali, i-petroleum, ukwenza iphepha, ukucubungula ukudla, ubunjiniyela basolwandle kanye nezinye izimboni.

Xhumana nathi

imininingwane yomkhiqizo

Ukukhetha impahla eluhlaza

Sebenzisa ishidi lensimbi engagqwali engu-904L noma umucu kumazinga we-ASTM A312 / A312M noma we-EN 10216-5.

Ukubumba

Gcoba ishidi noma hlubula libe yisimo sepayipi ngokugoqa okubandayo noma inqubo yokudweba ebandayo.

Ukushisela

Ukusebenzisa i-TIG (i-tungsten pole argon arc welding) noma i-MIG (i-metal inert gas protective welding). Imingcele yokushisela idinga ukulawulwa ngokuqinile ngesikhathi senqubo yokushisela ukuze kuqinisekiswe ikhwalithi yokushisela.

Ukwelashwa kokushisa

Ngemuva kokushisela, ukwelashwa kwesisombululo esiqinile kungadingeka ukubuyisela ukumelana nokugqwala kanye nezakhiwo zemishini zezinto.

Ukuhlola nokuhlola

Yenza ukuhlola okungonakali kwepayipi elishiselwe, njengokutholwa kwe-ultrasonic, ukutholwa kwe-radiographic, njll., ukuze uqinisekise ukuthi i-weld ayinawo amaphutha. Ukuhlolwa kwezakhiwo zemishini nokuhlola ukumelana nokugqwala kwenziwa kanyekanye.

Ukwelashwa kwendawo

Ngokusho isidingo, ashiselwe ipayipi ukwelashwa surface, ezifana pickling, passivation, njll, ukuthuthukisa ukumelana ukugqwala.

Ukupakisha nokulethwa

Ukupakisha amapayipi ashiselwe afanelekayo ukuze kuqinisekiswe ukuthi akukho monakalo ngesikhathi sokuthutha.

Ipayipi elishiselwe insimbi engagqwali engu-904L ilungile ezinhlelweni eziningi zezimboni ngenxa yokumelana nokugqwala okuhle kakhulu. Lapho ukhetha futhi usebenzisa lezi zinto, qinisekisa ukuthi izindinganiso ezifanele kanye nokucaciswa kuyalandelwa ukuze kuqinisekiswe ukusebenza nokuphepha kwezinto. Ngesikhathi esifanayo, ngoba intengo ye-904L yensimbi engagqwali iphakeme kakhulu, ngakho-ke ekukhethweni kwezinto ezibonakalayo, kufanele kucatshangelwe ngokuvumelana nezidingo zangempela zohlelo lokusebenza kanye nenzuzo yezindleko.
