Flanges and 18″ Pups were welded to each outlet of a 6″ Standard Lateral that we fabricated for a Hydrostatic Pressure Test. We then added blind flanges and filled the test fitting with water. Though we guarantee our 6″ STD Laterals to have a maximum operating pressure of 480PSI, this test piece held strong at 600PSI. Looks like we’re gonna need a bigger pump to see just how high they’ll go!
