API 600 Gate Valve Bonnet Castings

Bonnet ke ho koaloa ha khatello ea ho koala ha valve ea heke ea bolted-bonnet ho API 600. E na le lebokose la ho roala, bonnet bolting flange, le backseat - 'me e tlameha ho lahlela ka mokhoa o hloekileng, mochine o nepahetseng, le ho fetisa tlhahlobo ea hydrostatic ntle le ho lutla. Porosity ka ho etsa bonnet ha se taba ea litlolo: ke karolo e lahliloeng e fumanoeng ka nako e mpe ka ho fetesisa, kamora hore lihora tsa machining li tsetetsoe.

Ke ka lebaka leo baetsi ba li-valve ba tsoang lefats'eng ka bophara ba tsoang Ningbo Ruican. Re hlahisa libono tsa li-valve tsa heke ka ASTM A216 WCB carbon steel (e nang le WC6, WC9, CF8M, le CF8 likhetho tse sa hloekang) ka ho etsa matsete, ho fana ka li-castings tse teteaneng, tse lutlang tse nang le sepakapaka se setle ka ho fetisisa sebakeng sa lebokose la lintho. Ts'ebetso e haufi-ufi e fokotsa tumello ea ho sebetsa sebakeng sa flange, sebaka sa tšoelesa le sefahleho sa gasket, e fokotsa nako ea ho sebetsa le litšila ha e bapisoa le libone tsa lehlabathe.

Kamora ho beoa le ho tloaeleha, libono li entsoe ka mochini oa CNC ka botlalo - sefahleho se sephara, sefahleho se phahamisitsoeng (125–250 µin AARH serration ho ea ka ASME B16.5), bore ea mabokose, setulo se ka morao, le masoba - mananeo a CNC a notletsoe litšoantšong tsa hau. Li-castings li ka fanoa ka tlhahlobo ea bopaki, NDE-ea hlahlojoa (RT/UT/MT ho latela litlhoko tsa tlatsetso tsa ASME B16.34), 'me li ngotsoe ka litifikeiti tsa thepa tsa EN 10204 3.1 le ho latella mocheso ka botlalo.

Litlhaloso Tse Bohlokoa

Near-Net-Shape Economics for Valve Makers

Bonnet ea sand-cast 2" ea sehlopha sa 300 e ka jara 8-12 mm ea thepa ea machining hohle, eo boholo ba eona e fetohang lichifi. Ts'ebetso ea matsete e fokotsa thepa ho 1.5-3 mm lifahlehong tse entsoeng ka mochine 'me e hlahisa lebokose la lintho tse ka hare ho sebopeho. ka 500-5,000 sengoathoana meqolo ea selemo le selemo.

Hobaneng U Khetha Ningbo Ruican

• Lilemo tse 17+ ho lahlela likarolo tsa valve tse bolokang khatello (libone, 'mele, li-discs, litulo, litšoelesa, lijoko)
• Lenaneo le felletseng la alloy: WCB, WC6, WC9, CF8, CF8M, CF3M, duplex, le monel ka kopo
• Setso sa NDE sa indasteri ea li-valve: mekhoa ea radiography le ho amoheloa ka ASME B16.34
• Phepelo e felletseng ka mochini - kenya ka kotloloho mohala oa hau oa kopano
• Sistimi ea boleng bo netefalitsoeng ea IATF 16949 e nang le merero e inehetseng ea boleng ba karolo ea li-valve
•
