I-Trunnion Efakwe Ngaphantsi Komhlaba I-Welded Fully Ball Valve China Manufacture
Yintoni ivalvu yebhola engaphantsi komhlaba?
I-NortechIvalve yeBhola edibeneyo epheleleyoIphuhliswe ngabasebenzi bobuchwephesha bobunjineli abavela kumzi-mveliso abanamava angaphezu kweminyaka engama-30 kuyilo kunye nokuveliswa kwevalvu yoxinzelelo oluphezulu kunye nomgangatho wamva nje wobugcisa wamazwe ngamazwe, isetyenziselwa kakhulu ukuthuthwa kwepayipi yepetroli, igesi yendalo kunye nenkqubo yepayipi yegesi kwiidolophu.
Iimpawu eziphambili ze-Underground ball valve
Ulwakhiwo lweValve oludibeneyo lwe-1.lntegral
Ihlanganiswe ngokupheleleyo ngentsimbi eqingqiweyo. Izinto zokubumba zivavanywa nge-ultrasonic ngokweemfuno zokufumanisa iziphene ze-ASME non-destructive examination (NDE). Isiphelo se-buttweld sivavanywa ngokungena kwamasuntswana, iinkonzo ze-RT ziyafumaneka.
2. Ukumelana nokugqwala kunye nokumelana noxinzelelo lwe-sulfide
Isibonelelo esithile sokugqwala sigcinelwe ubukhulu bodonga lomzimba, xa kujongwa ukugqwala. Isiqu sentsimbi yekhabhoni, umngxuma osisigxina, ibhola, isihlalo kunye neringi yokugcina isihlalo zifakwa kwi-nickel plating yamakhemikhali ngokwe-ASME B733 kunye ne-B656. Ukongeza, izixhobo ezahlukeneyo ezichasene nokugqwala ziyafumaneka ukuze abasebenzisi bazikhethe. Ngokwesicelo sabathengi, izixhobo zevalvu zinokuhlangabezana neemfuno ze-NACE MR 0175/1S0 15156 okanye i-NACE MR 0103, kwaye ulawulo olungqongqo lomgangatho kunye nokuhlolwa komgangatho kufuneka kwenziwe ngexesha lenkqubo yokuvelisa ukuze kuhlangatyezwane ngokupheleleyo neemfuno kwimigangatho kwaye kuhlangatyezwane neemeko zenkonzo kwindawo yesulfurization.
5. Isakhiwo sesihlalo
Ngokwesicelo somthengi, isihlalo singenziwa njenge-DBB, DIB-1, DIB-2, ukuhlangabezana neemfuno zeemeko zokusebenza ezahlukeneyo.
Isihlalo seDBB
Isihlalo DIB-1
Isihlalo DIB-2
