Bonet minangka penutupan penahan tekanan saka tutup gapura bolted-bonnet menyang API 600. Iku nggawa kothak isi, flange bolting bonet, lan kursi mburi - lan kudu dibuwang kanthi resik, mesin kanthi tepat, lan lulus tes hidrostatik tanpa bocor. Porositas ing casting bonet ora masalah kosmetik: iku bagean scrapped ditemokaké ing wayahe paling awon, sawise jam mesin wis nandur modhal.
Iki kok tutup manufaktur global bonet sumber saka Ningbo Ruican. We gawé tutup tutup gapura ing ASTM A216 WCB baja karbon (karo WC6, WC9, CF8M, lan CF8 opsi stainless) dening casting investasi, ngirimke castings kandhel, bocor-nyenyet karo banget minangka-cast lumahing Rampung ing area kothak stuffing. Proses cedhak-net-wangun minimalake sangu mesin ing flange, wilayah kelenjar, lan pasuryan gasket, ngurangi loro mesin wektu lan sampah materi dibandhingake bonet wedhi-cast.
Sawise casting lan normalisasi, bonet wis CNC machined lengkap - flange pasuryan, munggah rai rampung (125-250 µin AARH serration saben ASME B16.5), stuffing kothak bolongan, backseat, lan bolongan kandang jaran - karo program CNC dikunci kanggo gambar Panjenengan. Castings bisa diwenehake bukti-dites, NDE-dipriksa (RT/UT/MT saben ASME B16.34 syarat tambahan), lan didokumentasikake karo EN 10204 3.1 sertifikat materi lan traceability panas lengkap.

Bonet 2" kelas 300 wedhi bisa nggawa stok mesin 8-12 mm ing endi wae, sing paling akeh dadi kripik. Pengecoran investasi nyuda saham dadi 1.5-3 mm ing pasuryan mesin lan ngasilake profil internal kothak isian minangka cast. Digabungake karo baja sing luwih resik (gas sing luwih murah lan tingkat inklusi saka proses silika sol 5% sing luwih murah tinimbang biaya silika sol saben 5% rampung). 500-5.000 potongan volume taunan.
