409 410Ukuqina okuphezulu amapayipi ashiselwe insimbi engagqwali yensimbi ye-Martensitic Lesi sihloko siza kuqala kanye no-409 410

Ubulukhuni obuphezulu be-martensitic insimbi engagqwali yepayipi yokushisela yezimboni isetshenziselwa ikakhulukazi amandla aphezulu nobulukhuni bezicelo, futhi idinga ukumelana nokugqwala okuthile. Insimbi engagqwali ye-Martensitic yethiwa ngobulukhuni bayo obuphezulu namandla ngemva kokwelashwa kokushisa, futhi ifaneleka ukwakhiwa kwamathuluzi okusika, iziphethu, ama-bearing, ama-valve, imizimba yokupompa nezinye izingxenye.

Xhumana nathi

imininingwane yomkhiqizo

Ukukhetha impahla eluhlaza

Khetha ishidi lensimbi engagqwali eqinile ye-martensitic noma umucu we-ASTM A268 / A268M noma i-EN 10297-2.

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 kanye nokwelashwa kokuguga kungadingeka ukuze kubuyiselwe izakhiwo zemishini kanye nokumelana nokugqwala kwezinto.

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.

Uma ukhetha futhi usebenzisa i-high-hardness martensite insimbi engagqwali amapayipi ashiselwe, imvelo yabo yesicelo esithile kanye nezidingo zokusebenza kufanele kucatshangelwe ukuze kuqinisekiswe ukusebenza nokuphepha kwezinto. Ngesikhathi esifanayo, izindinganiso ezihambisanayo kanye nokucaciswa kuzolandelwa ukuze kuqinisekiswe ikhwalithi yamapayipi ashiselwe.
