Casing head spool is the very important equipment used in drilling process,casing spool can control the wellhead pressure,casing spool are often flange ended on the top of the casing head and connected with the bottom of the tubing head then become a part of the wellhead system of the oil well.
The 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.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.
Space Spool / Riser Spool is a sort of wellhead adapter spool and made of integral alloy steel forging, the wellhead adapter spool is designed and manufactured in accordance with API 6A, and have end connectors in same size or different size, rated working pressure. The spacer spool / riser spool is pressure-containing piece of equipment. As the part of wellhead equipment, the adapter spools have no provision for suspension of tubular member and for sealing of tubular members. The spacer spool provide separation between two components.
