SERVICE OF RESTORING TOOL JOINTS THROUGH BUILD-UP AND HARDBANDING

Service of Restoring Tool Joints through Build-Up and Hardbanding.

Since autumn 2019, DENIMEX along with DJ Tubular Service Pte has launched a new service: hardbanding and build-up of drill pipe tool joints.

The high prices of new drill pipes create the search for and implementation of new technologies for the refurbishment thereof. Drill pipe wearing off is characterized by a gradual reduction in the wall thickness as a result of drilling operations. Accordingly, the priority direction for solving this problem is the development of technology of restoring tool joints that were already in operation, and the use of innovative hardbanding technology of applying of wear-resistant material strips onto DP tool joints.

HARDBANDING IS:

  • A reliable protection of tool joints: under conditions where drilling depth increases, more and more load is put on the joint and on the string itself, while the replacement of the string is too expensive;
  • An increase in surface hard-wearing and operational life of DP: due to the applied hardbanding, the total contact area of DP with surface is reduced, thus resulting in lower friction and tightening;
  • High performance hardbanding alloys: DJ Tubular Service Pte invented the most effective, durable and non-cracking alloys. The CR2000 product has optimal properties and can be reused at a minimum cost.
