UkuthethelelwaUngowemboni yezinto zokwakha, ukusetshenziswa kwawo kabanzi kabanzi, kusukela kumqondo:ukuthethelelwaIngabe insimbi isetshenziswa ingcindezi, ngokuguquguquka kwepulasitiki ukwakheka ukwakheka okudingekayo noma amandla afanele okucindezela entweni.
Ukuthethelelaukusetshenziswa kwemishini yokwakha ekwakheni ukwakheka kwesitoko sebha, ngokuvamile akwaziukuthethelelaUbuciko obunzima ngokwengeziwe, badinga umthamo omkhulu wokucubungula, kepha isakhiwo esibunjiwe sihlangene, hhayi ukuthambekela ekulimaleni kwangaphakathi, ngakho-ke kusetshenziswa kabanzi ekufuneni izingxenye, njenge-valve squem, i-valve stem valve , Ukwenza umzimba nawo usetshenziswa kabanzi.
Uma kuqhathaniswa nokukhokhwa, umzimba wama-valves anezinkinga ezifanayo, ukuqina okungcono, ubuqotho obungcono, izici ezingcono kakhulu, nephutha elincanyana. Ukwakhiwa Kwezindlela Zokuqondisa (ipayipi) kunokwenza okuphezulu kunama-carings ngokuya ngamandla aphelele kanye nengcindezi.
Amandla aphezulu - ashisayoukuthethelelaIkhuthaza i-crystallization kanye nokuhlaziywa kokusanhlamvu, okuvumela lokho okuqukethwe ukufezekisa amandla aphezulu kakhulu nokuvumelana nokuhluka okuncane kusuka engxenyeni kuya engxenyeni. Izinhlayiya zihamba kahle eduze kwephrofayili yomzimba. Lezi zinhlaka eziqhubekayo zisiza ukunciphisa izehlakalo zokukhathala noma amaphutha ajwayelekile.

Ubuqotho bezinhlekelele - Ukwenza kuqede iziphambeko zangaphakathi futhi kukhiqize isakhiwo esihambisanayo nesingaguquki se-metallographic, siqinisekisa ukusebenza okuhle kakhulu.UkuthethelelwaNikeza impilo yenkonzo ende nensizakalo engenazinkinga lapho ingcindezi nokugqwala kwe-crystal kuyinkinga enkulu.
Ukuthembela - Ubuqotho bezinhlekelele Ukwenza ukuqeda iziphazamiso zangaphakathi futhi kukhiqize isakhiwo esihambisanayo nesingaguquki se-metallographic, kuqinisekiswe ukusebenza okuhle kakhulu. Ukukhonjiswa kuhlinzeka ngempilo yenkonzo ende nensizakalo engenazinkinga lapho ingcindezi nokugqwala kwe-crystal kuyinkinga enkulu.
Ukuqinisekiswa kwekhwalithi - ngokusebenzisa ukuthethelelwa, ngokuvumelana kwayo kanye nekhwalithi ephezulu, isidingo semisebe ye-X-Rays for Class 1 CAST PARTS iyaqedwa. I-US Navy ibamba isimo esifanayo lapho sisebenzisa izithembiso ezinjengezakhi zemikhumbi yenuzi kanye nezithwali zendiza. Zonke izidingo zekhodi ze-ASME zokuthethelelwa zingukuhlola kwe-ultrasonic (ut), ukuhlolwa kwama-magnetic partencle (MT) noma ukuhlolwa kwe-liquid penetation (PT). Ukukhokhiswa kwesikhafu okutholwe yi-Ut, MT, noma izindlela ze-PT zivamile kakhulu. Izakhi zithengwa ngezikhathi ezilawulwayo zokulethwa, ngakho-ke ukulethwa kwe-valve kuthembeke kakhulu.
Ukucushwa kwenkomba komzimba we-valve - Amandla okukhathala okukhohlakala angaphezu kwezikhathi ezi-3 eziphakeme kunalezo zokuphonsa ngaphansi kwesimo sezinguquko ezinkulu zokushisa.
Inkampani esemqokai-flange, ukuthethelela, Ukwenza ukucubungula, noma yimiphi imibuzo noma udinga ukwamukela ukubuza futhi uxoxisane.
