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 tolerance is ±0.5 mm.
3. Tenaris is not responsible for the specifications of non-Tenaris Material Product Data Sheet. Consider the ratings above as reference values only. Internal Pressure Ratings based on analytical estimation (Structural).
4. Due to the oversized OD there is an increase in contact pressures and as a result there is a higher risk of galling. To minimize this risk and assure a proper make-up, extreme care shall be taken when making-up the connection:
   1. Correct dope application
   2. Constant make-up speed
   3. Proper Alignment
   4. Tong chucks shall be placed on the accessory body and not over the thread/seal area in order to avoid any additional contact pressure on the connection produced by the tong pressure which may lead to galling.
5. Accessory Performance ratings: The referenced accessory is non-Tenaris material. Tenaris is not responsible for the specifications from the material manufacturer’s Product Data Sheet so consider the pipe ratings above as reference values only.
6. Accessory Tensile and Pressure ratings are based on the minimum between the casing hanger and the nominal pipe strengths.
7. The connection manufacturing shall be performed based on Tenaris Specification.
8. For Wedge family connection Acc. Eff is related to Connection Yield Strenght.
