Notes

(1) The torque values presented apply to all Special Bevel (including Wider Face), Corrosion Barrier or Recess Free Bore options of the selected products.

(2) Box outside diameter tolerances are according to connection drawing.

(3) Due to the oversized box outside diameter there is an increase in contact pressures and as a result there is a higher risk of galling. Follow Tenaris Running Manual indications for proper make-up.
