carbon steel din standard globe valve

Timawagwiritsa ntchito kuti tikupatseni chidziwitso chabwino kwambiri.Ngati mupitiliza kugwiritsa ntchito tsamba lathu, tikuganiza kuti ndinu okondwa kulandira ma cookie onse patsamba lino. Kuyambira 1953, BFESpA yakhala ikuyang'ana kwambiri pakupanga ma valves achitsulo.BFE ndi mtundu wolemekezeka padziko lonse lapansi, womwe umadziwika ndi mapangidwe ake apamwamba komanso khalidwe. kukhazikitsidwa kulamulira kwathunthu pa BFE Mavavu amapangidwa m'mafakitale awiri: kuzindikira koyamba kwa zinthu zamtengo wapatali kunakwaniritsidwa mufakitale yomanga ya Bosisio Parini, pomwe ma billets ndi ma billets adatsimikiziridwanso ndikupangidwa pansi pa ulamuliro wonse, katundu wakuthupi ndi njira zopangira. M'malo mwake, timayika kufunikira kwakukulu kwaubwino ndipo takhazikitsa labotale yoyesera yokhala ndi zida zowongolera zinthu zisanachitike, panthawi komanso pambuyo popanga. The processing wa forgings ndi zigawo zikuluzikulu ikuchitika mu fakitale yaikulu ya Albano S. Alessandro. Chifukwa cha mapangidwe oyendetsedwa a CAD, miyezo yodziwika bwino ndi makasitomala amakwaniritsa miyezo yapamwamba kwambiri. Zotengera zoyendetsedwa bwino ndi zida zogwiritsira ntchito zimagwiritsidwa ntchito pokonza ma valve ambiri ovomerezeka. , makina angapo a CNC amatha kukonza ma valve ochepa.Ndalama zambiri zimapanga zotsatira zabwino, kukhathamiritsa luso la kupanga ndi kupititsa patsogolo luso. Kapangidwe kamangidwe: mlingo wapamwamba kwambiri 1500-API 602, BS 5352, NF M87.412.Grade: 2500 ndi 4500-ANSI B16.34. Kapangidwe kamangidwe: ANSI B16.34.Grade: mpaka mapaundi a 4,500, ovomerezeka ndi apadera, masukulu apakatikati akupezeka pa pempho. Mapeto opangira matako akugwirizana ndi: ANSI B16.25.Kutsatana ndi maso: ANSI B16.10 mtundu waufupi. Mtundu: Valve yachiwiri ya mpira kapena valavu yachipata yapawiri yokhala ndi valve ya singano. Kuphatikiza kwapadera: ikhoza kukhala ndi valavu yoyendera ndi manja a jekeseni malinga ndi zofunikira. Kapangidwe kamangidwe: ANSI B16.34; B31.1; B31.3 ndi MSS-SP84. Maphunziro: Malinga ndi ANSI B16.34. Kuchuluka kwa mapaundi a 4,500. Kukula kwa doko: Malinga ndi zomwe makasitomala amawauza. Maziko oyesera: API 598 ndi BS 6755. Kuyika chizindikiro: MSS SP25. Maziko oteteza moto: API 6A kapena BS 6755. Kapangidwe kapangidwe: API 6A. Mulingo watsatanetsatane wazinthu: PSL 1, PSL2 ndi PSL3. Gulu: 2000, 3000, 5000 ndi 10000 PSI Mapangidwe okhazikika: ASME B16.34-BS5351-API 6D. Zidutswa ziwiri kapena zitatu za bawuti kapangidwe-wolimba mpira-wofewa mpando-anti-kuphulitsa kunja valavu tsinde kapangidwe odana ndi malo amodzi chipangizo mbali kulowa-moto chivomerezo- ISO 5211 doko lodzaza zokha zokha kapena doko lochepetsedwa.
