Abstract
A replaceable sleeve insert for a choke assembly is disclosed, wherein the replaceable sleeve insert has a tubular member coaxially and sealingly retained within an upper body section of the choke assembly. The tubular member is also sealed against the bonnet. The tubular member has an inner diameter sufficient to accommodate coaxial linear displacement of a shuttle assembly and an outer diameter sufficient to fit within an upper body orifice in the upper body section. At least one attachment member outwardly extends from the tubular member and is retained between the upper body section and the bonnet. The tubular member has an opening in the sleeve wall to provide fluid communication from the choke inlet to the interior of the tubular member. A method of assembling a choke with a replaceable sleeve insert is also described.
