Pipeline Construction

A crew was at the 20 inch pipeline valve ("pig launcher") today preparing for a pressure test of the 20 inch pipeline section.



The crew was torquing bolts on a valve to 800 foot pounds using special torque wench.



Once the bolts on the valve were torqued to the correct amount, they started filling the pipeline with water. When all of the air in the pipeline is displaced with water, the pipeline will be pressurized to 2,100 PSI for the test.
