Hot Tapping & Line Stopping

  • In our current operations, we have established a valuable partnership with Tritorc company to deliver Hot tapping and Line stopping services. Due to complexity of this scope we are presently utilizing their expertise to offer these services.

  • However, our future objective is to acquire the necessary equipment and enhance our personnel's capabilities to conduct these services independently, moving towards self-sufficiency in this area. Hot Tapping or Online drilling is the specialized engineering method of connecting a new branch pipeline to the existing piping system, pressure vessels, storage tanks or any other process equipment without the need of shut down / production interruption.

  • LINE STOPPING SERVICES
  • Line stopping is an interventional technique used to temporary isolate a section of pipeline, with a mechanical inserted and activated stopple head, to undertake maintenance activity or repair works on downstream pipeline. Line stops can be performed with permanent/ temporary bypass to enable continuous production while the pipeline section is isolated.

  • This method employs a Tapping Machine, a Full bore valve (typically know as hot tapping valve) and a Hot tap Fitting (Weld o let/Stub with RF Pad/Full Encirclement Split Tee) that is either welded or bolted to the run pipeline. Hot Taps can be performed safely on most types of pipes, ranging from carbon steel to GRE.

  • The Services can be carried out on systems containing oil, gas, fuel, steam, water and many other line mediums with pressures up to 1480 PSIG @ 100°F. Our services are performed in line with relevant industry standards - API and Shell DEP specifications
