installed in the PT, and the pipeline was pressurized to 150 psi at the PT. For this <br />phase of the hydrostatic testing, a calibrated test gauge was used to measure the <br />pressure. After afour-hour pressurization phase, the pressure in the pipe was <br />reduced to 140 psi. After cone-hour period had passed, the pressure was again <br />measured. The pressure was found to be still at 140 psi, indicating no loss of <br />pressure. Again, per the PPI procedure, it would have been acceptable if the <br />pressure in the pipeline had dropped by up to 7 psi. During both phases of the <br />hydrostatic test, the pipeline was visually inspected for leaks, and none were found. <br />The entire 24-inch HDPE section of the Storke aipeline was therefore <br />hydrostatically tested and found to be leak-tight. The test pressure of 140 psi is <br />higher than any normal operating pressure (130 psi max.) that the pipeline is likely <br />to experience. It is recommerided,that the new Storke pipeline be accepted for use, <br />and that it be put into service as soon as it is scquired. <br />In addition, the Storke pipeline will be routinely tested by hydrostatic <br />methods during its operating lifetime. It is planned that Climax personnel will <br />perform a hydrostatic test once a year so that the pipeline integrity can be verified. <br />10 <br />
