Summary of the Project:
Wellube has successfully completed hot tapping and line stopping with a customised mechanical head on a 16” line (which was connected to a 24” main line) and replaced the damaged 24” gate valve in the fire water cement line.Client Requirement:
The client had a damaged 24” gate valve in their fire water tank line which needed to be replaced without interruption to the full firefighting system.Challenges faced
- Complexity involving executing hot tapping on a cement lined pipeline
- As the valve was old, the removal of the old stud & bolts from the valve by hot bolting was also a concern
Unique Solution delivered
Wellube team visited the site and had discussions with the client to develop a customised solution considering the age of the pipeline which is over 20 years. Based on their inputs, we performed an inhouse mock-up test on a pipe sample provided by the client to confirm the ideal line stop operation for the cement pipeline. After the successful mock-up test, we modified our 16” mechanical head equipment to suit the cement lined pipe’s internal diameter. We also designed 3 different outside diameter elements for installing in the mechanical head.Benefits delivered
- Completed the project ahead of schedule
- Achieved 100% seal on the cement line
- Fully HSEQ compliant
