Drilling spool is designed to allow smooth circulation of mud in well and BOP hook up. Drilling spools usually have the same nominal end connections and same nominal side outlet connection but it can be different as per the customer's requirements.
Drilling spools can be supplied in all standard API 6A sizes and types with any combination of flange or hub sizes, material grades, prssure rating and PSL level. Each drilling spool is manufactured to the customer's requirements. Welding performed conform to the applicable API standard and the provisions of ASME Section IX. Each spool is drift tested to ensure that access to the well-bore is not restricted.
Basic material of construction is alloy steel. For corrosion resistance, overlays like SS316L or Inconel 625 can be incorporated to improve product life if required.
