BRORN Non-Selective Landing Nipple
(ORN-Type) (Bottom No-Go)

Model “BRORN” Nipple is a bottom No-Go seating nipple designed for use in single nipple installations or as the bottom nipple when placed with a series of “BROR” landing nipples. This is due to the restricted internal dimension (No-Go) machined into the bottom of the landing nipple. This restriction has a smaller ID in comparison to the Seal Bore ID.

The Model “BRORN” Profile Nipple can be used in heavy tubing applications, as the blanking plug offers a higher pressure rating than the normal weight tubing blanking plugs.

Applications:
  • Land blanking plugs to shut in well or test the production tubing.
  • Land velocity type safety valves.
  • Land equalizing check valves.
  • Land chokes to reduce surface flowing pressures.
  • Land instrument hangers such as pressure and temperature recorders.
Features:
  • Internal sealing bore for maximum sealing capacities.
  • Nipple bore compatible with tubing size and weight to permit flow capacity.
  • Designed for standard tubing weight.
  • Premium threads available upon request.
  • Premium grades of material available upon request.
