I-Trunnion Egibele Ngaphansi Komhlaba Eshiselwe Ngokugcwele I-Valve yase-China Yokukhiqiza
Iyini i-Underground ball valve?
NortechI-Valve Yebhola Ehlanganisiwe Egcweleithuthukiswa ngabasebenzi bezobuchwepheshe bobunjiniyela abavela efektri abanesipiliyoni seminyaka engaphezu kwengama-30 ekwakhiweni nasekukhiqizeni i-valve enengcindezi ephezulu kanye nezinga lezobuchwepheshe lakamuva lamazwe ngamazwe, isetshenziswa kakhulu ekuthuthweni kwepayipi lebanga elide likaphethiloli, igesi yemvelo kanye nohlelo lwamapayipi egesi. emadolobheni.
Izici eziyinhloko ze-Underground ball valve
1.lntegral Valve Ukwakheka
Igcwele i-welded ngensimbi engumgunyathi.Izinto zokubumba zingaphansi kokuhlolwa kwe-ultrasonic ngokuvumelana ne-ASME non-destructive examination(NDE) izidingo zokuthola amaphutha.I-buttweld ending ingaphansi kokuhlolwa kokungena kwezinhlayiyana,izinsizakalo ze-RT ziyatholakala.
2.I-Corrosion Resistance kanye ne-sulfide Stress Resistance
Isibonelelo esithile sokugqwala sigcinelwe ukujiya kodonga lomzimba, uma kucatshangelwa ukugqwala.Isiqu sensimbi ye-carbon, shaft egxilile, ibhola, isihlalo kanye neringi yesibambi sesihlalo zingaphansi kokufakwa kwamakhemikhali e-nickel ngokusho kwe-ASME B733 kanye ne-B656. Ngaphezu kwalokho, ukumelana nokugqwala okuhlukahlukene Izinto ezisetshenziswayo ziyatholakala ukuze abasebenzisi bazikhethe. Ngokwesicelo samakhasimende, okokusebenza kwevalvu kungahlangabezana nezidingo ze-NACE MR 0175/1S0 15156 noma i-NACE MR 0103, futhi ukulawulwa kwekhwalithi okuqinile kanye nokuhlolwa kwekhwalithi kufanele kwenziwe ngesikhathi sokukhiqiza ukuze ukuhlangabezana ngokugcwele nezidingo emazingeni futhi uhlangabezane nezimo zesevisi endaweni ye-sulfurization.
5. Isakhiwo sesihlalo
Ngokwesicelo sekhasimende, isihlalo singaklanywa njenge-DBB, DIB-1, DIB-2, ukuze sihlangabezane nezidingo zezimo zokusebenza ezahlukene.
Isihlalo se-DBB
Isihlalo DIB-1
Isihlalo DIB-2
