Remanufactured Drilling Spools and Fittings

Petroleum Oil Tools remanufactures various types and sizes of flange drilling (diverter) spools, studded drilling spools, and hub drilling spools for blowout preventer stacks. We also remanufacture spacer spools, risers, and diverter spools under strict API 16A specifications.

  • Our drilling spools can be individually remanufactured to meet height and outlet requirements.
  • Our drilling spools can be remanufactured with flanged or hub connections.
  • Our spools are drift tested to prevent restriction to the well-bore.
  • Welding on drilling spools conform to API standards.
