Workstring Completion Tubing Rebuild
U.S. Pat. No. US 10,751, 824 B2
A premium build-up wire and procedure for the rebuilding of workstring completion tubing upset connections
Designed specifically for the rebuilding of workstring tubing upset connections our procedure provides outstanding metallurgical properties and weldability under unique conditions. This combination of carefully controlled heat and managed welding parameters, significantly reduces the possibility of burning through the original metal.
Once the weld has been properly applied, the weld material is milled to the connection's original specified diameter and the threads are re-cut.
When the cost and availability of new work string completion tubing is high and getting higher, our solution will save owners significant sums.
The rebuilt upset can then be applied with Duraband NC to protect it from any future wear. (see TubeBanding)
