Pipeline Construction

The morning was sunny and bright as the 24 inch pipeline started its 1/2 mile journey through the bore hole. A row of three excavators lifted the pipeline into position for its entrance into the bore hole.



As the pipeline is pulled into the bore hole it is coated with a bath of drilling mud to lubricate it.

It didn't take very long for the first two of four sections of pipeline to be pulled into the bore hole. While pipeline section number three was being welded onto the pull back pipeline, it was a good time to inspect the bore hole entrance.

Welding the last section of pipeline onto the pull back pipeline. This will create the over 1/2 mile of pipeline needed to pull into the bore hole. Once the welded joint completes the X-ray inspection, sandblasting and coating, it will be ready for the pulling.
