    Upset Type: IU Fluid Capacity w/o IPC (gal/ft): 0.13

    Fluid Displacement (gal/ft): 0.10

    MUT Values are based on a friction factor of 1.15. A copper-based thread compound with a 1.15 FF must be used to achieve the

    maximum performance for this connection. There is no published pressure rating for this connection.

    This asset must be handled with a lift nubbin. For more information, please consult Workstrings Operations.MW20 is a trademark of NOV Grant-Prideco.

The user is fully responsible for the accuracy and suitability of use of the technical information. Workstrings International cannot assume responsibility for the results obtained through the use of this material. No expressed or implied warranty is intended. Drill pipe assembly properties are calculated based on uniform OD and wall thickness. No safety factor is applied. The information provided for various inspection classes and for various wear conditions (remaining body wall) is for information only and does not represent or imply acceptable operation limits. It is the responsibility of the customer and the end user to determine the appropriate performance ratings, acceptable use of the product, maintain safe operational practices, and to apply a prudent safety factor suitable for the application. For API connections that have different pin and box IDs, tool joint ID refers to the pin ID. Per Chapter B, Section 4 VII of the IADC drilling manual, it is recommended that drilling torque should not exceed 80% of MUT.
