A choke is used to control the flow of fluids and is usually mounted on or close to the Christmas tree. 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/ceramic or stainless steel/tungsten carbide or similar durable material.
D-TUFF Choke Beans are lined with a high hardness, abrasion and corrosion resistant 98% Alumina Ceramics or Tungsten Carbide liners, to protect them from corrosive and abrasive wear.
WE manufactures a big range of bean chokes to match 'OCT' Type FC140, 'ThronillCraver', Gray Tool', Cameron' & types. These are manufactured with a precise diameter hole that forms the choke, through which all the abrasive/corrosive fluids must pass. Beans are available in a complete range of sizes, generally identified by the choke diameter stated in 64ths of an inch. |
