Tool Joint Build-up
This is an industry accepted procedure to prolong the service life of drill pipe and heavy weight drill pipe. A tool joint build-up by Stable Services will yield a connection with the same OD, seal face and bevel diameter as a new tool joint.

Tool Joint Hard-banding
Hard-banding to drill pipe, heavy weight drill pipe and drill collars is applied by automatic Gas Metal Arc Welding (GMAW).

Hard-facing
Stable Services specialises in hard-facing of stabilisers and other speciality tools. The type of hard-facing applied to drilling equipment has to be carefully chosen according to the drilling parameters and the drilling formation. Stable Services offers a range to suit all drilling conditions.

Stub Welding (Low Alloy Carbon Steel)
When drill stem members, such as drill collars, hole openers and other specialty tools become short, box weak from OD wear or pin weak through ID wear, they can be put back into service using this process, often referred to as “stubbing”. Stable Services is the industry leader in stub welding new material to existing worn tools thereby cost effectively restoring the physical dimension back to the acceptable requirements.

Stub Welding (Non-magnetic Materials)
As above, non-magnetic drill string components can also be stub welded.
Stable Services uses a semi automatic welding process. This process has
been approved to NS-1.

Heat Treatment
Specially designed electric thermally controlled ovens are used to ensure controlled pre-heat, interpass and post-weld heat treatment.
