I-Choke Valve Technology kunye nokuSetyenziswa kwee-Hard Alloys kwi-Choke Valves

    Iivalve ze-Choke ziyinxalenye ebalulekileyo kwiinkqubo zokulawula ulwelo lweoli, igesi, kunye namashishini ekhemikhali, asetyenziselwa ukulawula ngokuchanekileyo amazinga okuhamba, ukuzinzisa uxinzelelo, kunye nokuthintela umonakalo we-cavitation kunye nokuguguleka komhlaba. Ngaphantsi kweemeko zokusebenza ezigqithisileyo (uxinzelelo oluphezulu, i-corrosion, i-multiphase flow), izinto zemveli zihlala zisilela ukuhlangabezana neemfuno zokuqina kwexesha elide. I-alloys eqinile, efana ne-tungsten carbide (WC), enobulukhuni obuphezulu kakhulu, ukuxhathisa ukunxiba, kunye nokumelana nomhlwa, iye yaba lolona khetho lufanelekileyo kumacandelo aphambili evalve yokutshontsha. Eli nqaku liphonononga imigaqo yokusebenza yeevalvu eziminxayo, iindlela zokusilela eziqhelekileyo, kwaye lijolise kwiingenelo ze-alloys eqinile kwi-valve trims, izihlalo, kunye neendawo zokutywina.
