CobaltAlloy Installation Procedures

INSTALLATION AND HANDLING PROCEDURES

You have just invested in CobaltAlloy Production Tubing. Correct handling and installation procedures must be followed to ensure maximum life from your new tubing string.

Following these procedures will not increase your cost, however, it will help increase the return on your investment.

Inspection of Tubing on Arrival

CobaltAlloy recommends the following inspection points be followed;

1) Upon arrival of the tubing at the wellsite, the tubing and pup joints should be inspected for any damage during transport or forklift operations.

2) Stripping should be placed between the pipe on the racks on which the pipe is to be stored.

3) Thread protectors should be in place and firmly installed to protect all threaded connections

4) All CobaltAlloy tubing, Couplings and Pup Joints are shipped with a lead-free API modified thread compound applied to the threads.

Should special thread compounds be required;

a) The protectors should be removed.

b) The threads should be cleaned and dried.

c) The special thread compound can then be applied.

d) The pin end thread protectors should then be reinstalled to protect the threaded area from possible damage while the pipe is elevated through the “V” door into the derrick.

e) If the pipe is placed in the stands of the derrick to await the running of the string, pin end protectors should be left in place and removed as each length is installed.

f) For more information please refer to API RP 5C1, Section 2.9

Use Stabbing Guides
We recommend a Cobalt stabbing guide should always be used while running the CobaltAlloy tubing. This is to avoid damage to the threaded connection and any potential for damage to the protective layer.

For CobaltAlloy tubing installation using a stabbing guide the procedure is;

1) Open the stabbing guide and place over the tubing coupling.
2) Place pin end inside guide and make up the connection to the correct torque.
3) Open the stabbing guide and remove from the tubing coupling.

Make-up Connections

We recommend that API specifications be followed when making up CobaltAlloy tubing and pup joint connections.

Use Protective Drift Bars

Often workover crews will run drift bars or “rabbits” through the tubing while elevating the pipe through the “V door”. Should this be necessary, the drift bar should be made of UHMWPE or any other material that would not inflict damage on the tubing protective layer.

Note: Each joint of CobaltAlloy production tubing is drifted before it is shipped to the customer.

Pulling Tubing

When it becomes necessary to remove a tubing string from the well, it is important that you select the best tools (slips, power tongs, back up tongs, and elevators) that are available to do the job.

If the tubing to be pulled will racked in stands in the derrick, a resilient pad should be used on the rig floor to protect the pin end of the tubing. If such a pad is not available, thread protectors should be installed prior to setting the joint of tubing on the rig floor. It is also suggested that the thread protector be installed on the pin end if the tubing is laid down through the “V door.”

For Sucker Rod Pumped Wells

For maximum tubing asset lifecycle, we recommend installation of Cobalt Premium Sucker Rod Guides and Cobalt® X Coupling Centralizers. The CobaltAlloy Production Tubing internal protective internal layer was engineered to be compatible with ARPMAX Polymer Technology... Abrasion and Chemical Resistant, Self-Lubricating, Very Low Co-Efficient of Friction and Impact Resistant.
