Carbide Choke stem and seat 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.
