High Performance Drilling Casing Spool , Wellhead Casing Spool
Product Introduction
Casing spool has a straight bore bowl with 45°landing shoulder design which avoids damage to sealing areas by drilling tools and prevents test plug and bowl protector wedging problems when pressure is applied. Our Casing spools are normally furnished with threaded outlets and studded outlets and also can be manufactured by request. They can be used for single completions and model of dual completions.
Casing Spool uses a straight bore based on the same reliable design as the C-22 except the bowl is 2 inches deeper, permiting the acceptance of the minimal-deflection C-29 Casing Hanger. This allows extreme-load casing-hanging capacity compared with the C-22 profile. C-29 Casing Spools normally are furnished with studded outlets, and threaded outlets are available upon request. Bottom preparation can include PE seal or X-bushing secondary seals. HPE seals for high-performance frac wells are available upon request.
