Summary of the Project

Unique Group On-Site Engineering team successfully helped a client make a 4” branch from a 12” main pipeline using hot tapping thus avoiding shutdown

Client Requirement

The client approached Unique Group with the requirement to create a 4” branch connection from the existing 12” Natural Gas pipeline with minimum interruption to a large number of clients using the existing pipeline. The location of the branch connection was in a heavy traffic area which added to the challenge.

Unique Solution delivered

Unique Group after evaluating the client conditions, performed in-service welding and hot tapping on the 12” natural gas pipeline in order to create a 4” tap off to connect the CNG Pump.

The On-Site Engineering team chose this solution because it could be performed on the live pipeline in the shortest time, as the location for the branching was in a heavy traffic area and shutdown of the pipeline was not a viable option.
