Pipeline Construction

The pipeline welding crew was back working on welding the last few sections of pipe for the pipeline boring.



While one crew finishes the pipe welding, another crew started sandblasting and coating the welded joints.

Sandblasting the welds after they pass an X-ray inspection.

A protective coating of Powercrete® epoxy is applied to seal the welded pipeline joints. The epoxy coating will cure within minutes.
