2205 2507 Austenitic Ferritic Duplex Stainless Stainless Steel amapayipi ashiselwe (Ukumelana nokugqwala kwe-chloride)
Ukukhiqizwa kwamapayipi okushisela ensimbi engagqwali angu-2205 no-2507 ngokuvamile kuhilela lezi zinyathelo ezilandelayo:
Ukulungiselela impahla eluhlaza
Khetha 2205 noma 2507 ishidi noma strip efanelekayo ASTM A790 / A789 noma EN 10216-5 amazinga.
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.
2205 kanye ne-2507 amapayipi ashiselwe ensimbi engagqwali enezigaba ezimbili alungele ukusetshenziswa kwezimboni eziningi ngenxa yokumelana nokugqwala kwawo okuhle kakhulu kwe-chloride. Lapho ukhetha futhi usebenzisa lezi zinto, qinisekisa ukuthi izindinganiso ezifanele kanye nokucaciswa kuyalandelwa ukuze kuqinisekiswe ukusebenza nokuphepha kwezinto.
