Tungsten Carbide Choke Stem For Christmas Tree And Wellhead With Long Lasting Time
Tungsten Carbide Valve Choke Bean / Choke Seat / Choke Beans For Oil & Gas Industry
Choke bean used in the positive chokes for controlling the flowrate,and are usually mounted on or close to the wellhead equipment.High pressure gas/oil, with abrasive sand minerals passes through these chokes at high speed causing rapid wear. Bean chokes contain a replaceable insert, or bean, made from hardened steel or similar durable materials.
