Seal Headisetshenziselwa ukuvala ukuphela kwesiqukathi ukuze izingxenye zayo zokuhlukanisa imidiya zangaphakathi nezangaphandle, ezaziwa nangokuthi isembozo sokuphela.Iyingxenye yesitsha futhi ixhunywe kusilinda ngokushisela.
Ngokwezimo ezihlukahlukene zejiyomethri, ingahlukaniswa ibe yi-hemispherical, elliptical, dished, umqhele oyindilinga, igobolondo le-cone kanye nesembozo, phakathi kwayo ikhanda eliyi-hemispherical, inhloko eyi-elliptical, inhloko edayiwe, inhloko yomqhele eyindilinga yaziwa nangokuthi i-convex head. ingahlukaniswa ngekhanda le-butt welding kanye nekhanda le-socket welding, elisetshenziselwa imikhumbi ehlukahlukene kanye nemishini, njengamathangi okugcina, ama-heaters, ama-reactors, ama-boilers kanye nemishini yokuhlukanisa, njll. Izinto zokwakha ziyi-carbon steel (A3 20 # Q235 Q345B 16Mn, njll.), insimbi engagqwali (304 321 304L, 316 316L, njll.), insimbi ye-alloy, njll.
Isicelo:
Ikhanda liyingxenye ebalulekile yemishini yemikhumbi yokucindezela ku-petrochemical, amandla e-athomu, ukudla kanye nezimboni zemithi.
●Inhloko iyisembozo sokugcina emkhunjini wokucindezela, okuyingxenye eyinhloko ethwala ingcindezi yomkhumbi wokucindezela.Umsebenzi uwumsebenzi wokuvala.Okunye ukwenza okuphansi nangaphansi komkhumbi wokucindezela okumise okwe-can, kanti omunye ukuthi ipayipi selifinyelele ekupheleni kwalo futhi alisazukunwebeka, ngakho-ke ikhanda lisetshenziselwa ukuvala ipayipi ngendlela yokushisela.Okufana nomsebenzi wekhanda ipuleti eliyimpumputhe kanye nesivalo sepayipi, kodwa lezi imikhiqizo emibili ingasuswa.Ikhanda alikwazi ukuhlakazwa ngemva kokushiselwa.Ukufakwa kwamapayipi okusekela kuyimikhumbi yokucindezela, amapayipi, ama-flange, izindololwane, ezintathu, ezine kanye neminye imikhiqizo.
● Izinga lekhanda le-seal lihlobene ngokuqondile nokusebenza okuphephile nokuthembekile kwesikhathi eside komkhumbi wokucindezela.
●Ikhanda lophawu lingasetshenziswa ukwenza imihlobiso yengadi yomgodi womlilo.
