The “Make-up” process
At the “downhole” end of a drill pipe (drillstring), there is some sophisticated parts assembled to each other by a threaded connection. To be able to carry out this assembly of parts, with the high degree of accuracy that is required, ETS’ has a highly advanced ENERQUIP machinery, that is used for this operation.
In the work shop, the connection of several individual parts into an “assembly”, is referenced as the “Make-up” or “making” process and the disassembly of the parts is referenced as the “breaking” operation.
The make-up of assemblies, is one of the activities carried out in ETS’ workshop and it is performed by highly skilled technicians, following detailed instructions/procedures and as mentioned earlier, by use of the very advanced ENERQUIP makeup apparatus, making it possible to make an assemble by individually parts of “pipe fittings”, up to an outside diameter of 21” and up to a 50 ft total length of the assembly.
The ENERQUIP apparatus can operate with a very accurate torque force up to a maximum of 100.000 ft/lb. The specified torque will enable the individual pieces of pipe fittings to be held together without damaging the thread, but strong enough for the drilling operation, and afterwards make it possible to do the breaking of an assembly, so the individual parts can be replaced or reused.
