Choke Valve Technology na ngwa nke Hard Alloys na Choke Valves
valvụ choke bụ ihe dị oke mkpa na sistemu njikwa mmiri maka ụlọ ọrụ mmanụ, gas na kemịkalụ, nke a na-eji ahazi nke ọma ọnụego erute, kwụsie nrụgide ike, ma gbochie cavitation na mmebi mbuze. N'okpuru ọnọdụ ọrụ dị oke egwu (nrụgide dị elu, corrosion, multiphase flow), ihe ọdịnala anaghị emezu ihe achọrọ ogologo oge. Alloys siri ike, dị ka tungsten carbide (WC), na ike siri ike ha dị oke elu, nguzogide na-eguzogide corrosion, abụrụla nhọrọ kacha mma maka ihe mejupụtara valvụ mkpagbu. Edemede a na-enyocha ụkpụrụ ọrụ nke valvụ choke, ụdị ọdịda a na-ahụkarị, wee lekwasị anya na uru nke alloys siri ike na valvụ trims, oche, na mkpuchi mkpuchi.
