I-Trunnion Egibele Ngaphansi Komhlaba I-Welded Fully Ball Valve China Manufacture
Iyini i-Underground ball valve?
I-NortechI-Ashiselwe Ibhola Valve EgcweleYakhiwa ngabasebenzi bezobuchwepheshe bobunjiniyela abavela efektri abanolwazi olungaphezu kweminyaka engama-30 ekwakhiweni nasekukhiqizweni kwama-valve anomfutho ophezulu kanye nezindinganiso zobuchwepheshe zakamuva zomhlaba wonke, isetshenziswa kakhulu ekuthuthweni kwephayiphi likaphethiloli, igesi yemvelo kanye nohlelo lwamaphayiphi egesi oluhamba ibanga elide emadolobheni.
Izici eziyinhloko ze-Underground ball valve
Isakhiwo se-valve esihlanganisiwe esingu-1.
Ihlanganiswe ngokuphelele ngensimbi eyenziwe ngobumba. Izinto zokwakha zenziwa ngobumba olusebenzisa i-ultrasonic ngokwezidingo zokuthola amaphutha e-ASME non-destructive examination (NDE). Isiphetho se-buttweld sihlolwe ngobumba olusebenzisa i-particle, izinsizakalo ze-RT ziyatholakala.
2. Ukumelana Nokugqwala kanye Nokumelana Nokucindezeleka Kwe-sulfide
Imvume ethile yokugqwala igcinelwe ubukhulu bodonga lomzimba, uma kubhekwa ukugqwala. Isiqu sensimbi yekhabhoni, umgodi oqinile, ibhola, isihlalo kanye nendandatho yokugcina isihlalo kufakwe i-nickel plating yamakhemikhali ngokusho kwe-ASME B733 kanye ne-B656. Ngaphezu kwalokho, izinto ezahlukahlukene ezingamelana nokugqwala ziyatholakala ukuze abasebenzisi bazikhethe. Ngokwesicelo samakhasimende, izinto ze-valve zingahlangabezana nezidingo ze-NACE MR 0175/1S0 15156 noma i-NACE MR 0103, futhi ukulawulwa kwekhwalithi okuqinile kanye nokuhlolwa kwekhwalithi kufanele kwenziwe ngesikhathi senqubo yokukhiqiza ukuze kuhlangatshezwane ngokugcwele nezidingo ezindinganisweni futhi kuhlangatshezwane nezimo zesevisi endaweni ye-sulfurization.
5. Isakhiwo sesihlalo
Ngokwesicelo sekhasimende, isihlalo singaklanywa njenge-DBB, DIB-1, DIB-2, ukuze kuhlangatshezwane nezidingo zezimo zokusebenza ezahlukene.
Isihlalo se-DBB
Isihlalo DIB-1
Isihlalo DIB-2
