Make-up Acceptance Criteria

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:

CONNECTIONS

GROUP 1

Blue™

Blue™ Near Flush

Blue™ Thermal Liner

MS™

3SB™

HW™

PJD™

ER™

GROUP 2

Wedge Series 500™

MACII™

SLX™

PH4™, PH6™ and CS®

The use of a torque-turn monitoring system is

highly recommended for Group 1 connections.

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 ConnectionsRecommended make-up equipment

TURN MEASUREMENT RECOMMENDATIONS

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.

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

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.

This result will be achieved if

the recommended guidelines

for running and thread lock

compound application are

followed.

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:

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:

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.

.

.

VARIANTS 521, 561, 563, 551 AND 553

These connections have a make-

up 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.

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 buck-

on coupling. If face still fails to

reach the band, mark the pin and

coupling and set aside.

.

.

.

WEDGE SERIES 500™

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.

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.

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.

.


9/10

MACII™

This connection should have the

external seal in contact after

make-up.

PH4™, PH6™ AND CS®

These connections will make-up

to the external seal with no gap

visible.
