Running Manual

These guidelines indicate acceptance and rejection criteria to be used when making up TenarisHydril connections at the well site. Should you have any questions, please contact your local field services contact ([email protected]).

Connections nomenclature TenarisHydril Premium connections are divided into three types: Blue™ Series, Wedge Series 500™ and Legacy Series. For clarity, our premium connections series are organized in the following manner:

The use of a torque-turn Monitoring System is not necessary for Group 2 connections. If torque-turn equipment is used, verify calibration dates on load cells. Unless clearly stated, torque values published in TenarisHydril Data Sheets are for make-up with a running compound having a friction factor of 1. Use of other compounds may result in higher or lower torque values.

Group 1 Connections Recommended make-up equipment

Time measurements

Time measurement is useful but not necessary for monitoring the make-up of TenarisHydril premium connections. Dump valve recommendations 1. Check the dump valve opening time before the first make-up. 2. Test the dump valve by applying the torque-turm system to the pipe body.

3. Fix or replace the dump valve if the real make-up torque does not match the optimum make-up torque. Friction Factor correction

MAKE-UP ACCEPTANCE CRITERIA

The use of a torque-turn monitoring system is highly recommended for Group 1 connections.

1. Use

a turn transducer device independent of the power tongs. 2. Perform a test to ensure that one turn of the transducer device indicates one turn on the graph. 3. Use a turn transducer that can deliver preferably 1000 pulses per turn for an accurate reading.

For all Group I connections, torque values should be adjusted by multiplying by the corresponding friction factor. This applies for running compound and for thread lock compound as well.

Make-up acceptance criteria

Make-up curves shown throughout this Section are schematic. Some variations may be observed in real make-up graphs. For a correct interpretation of make-up graphs, it is important to consider the behavior exhibited by the joints that were previously run into hole. Any graph reflecting anomallies should be investigated (i.e., back out and inspect joint).

Group 2 Connections The primary make-up criteria for Group 2 connections is the attainment of target torque. As a secondary visual aid the following guide is applicable:

Wedge Series 500™ Friction factor correction

When running compound is employed it is recommended not to apply any friction factor correction, regardless of the recommendations made by compound's manufacturer. Use TenarisHydril published make-up torque. For thread lock compounds apply the following recommendations:

Variants 521, 561, 563, 551 and 553

.

These connections have a makeup band stencilled round the circumference of the pin OD. The face of the coupling should be within the range of the band.

.

.

. .

If the face of the coupling ends pass the maximum limits of the band, mark the pin and coupling and set both aside.

Variants 533 and 503

These connections have a wear indicator gap between the pin and box shoulders after make-up. This gap should always be visible.

.

Wedge Series 500™: Torque applied should be 15-20% over target torque regardless of the recommendations made by thread lock compound's manufacturers. Do not exceed 1.75 times minimum torque. TSH SLX™ and TSH MACII™ use maximum torque value from Data Sheet.

If the face falls short of the band, breakout the coupling, clean pin and box, and inspect for damage. Repair any damage. Reapply running compound and buckon coupling. If face still fails to reach the band, mark the pin and coupling and set aside.

When the gap is closed it is an indication that the connection is worn, and both pin and box should be marked and sent for re-cut.

Variants 511, 513 and 523

These connections have no make-up band on pin end. Correct make-up has been attained if no pin threads are visible after make-up. 8
