Plant engineers were experiencing multiple leaks on a 6” carbon steel discharge line that ran from the refinery to a discharge facility approximately 3.5 miles away. Because of the compromised line, the engineers determined that the refinery was inadvertently discharging treated waste water into the surrounding soil around the pipe line.
Obviously this situation was unacceptable to ODFJELL management and the pipe line was shutdown to alleviate the inadvertent discharge into the ground. As a result of the pipe line shut down, and at great expense, ODFJELL was forced to truck the treated waste water from the refinery to the discharge facility on a daily basis until a solution could be discovered.
Engineers made public a Request for Quote (RFQ) to rehabilitate the pipe using Cured in Place Piping (CIPP). While HS is a seasoned CIPP contractor, due to the length and pressure requirements of the discharge line, HS personnel determined that a Primus Line installation would be a much faster and economical way to rehabilitate the pipe line as opposed to using the CIPP method.
HS was the winning bidder and subsequently cleaned the pipe using an “air” pigging method. Once the cleaning of the pipe line was completed, HS video inspected the line to verify it was properly cleaned
and then successfully deployed the Primus Line Low Pressure Liner for approximately 16,000 linear feet. The project was a success and HS finished under budget and on schedule allowing ODFJELL to resume the normal use of the discharge line.
Chemours plant maintenance personnel had repeatedly repaired an aging 10”carbon steel water line that ran through the heart of the plant for approximately 1,400 linear feet (LF). This water line was located under cooling towers, buildings and a main road artery that made conventional excavation very difficult if not impossible.
Plant engineers contacted HS to seek out an alternative method of rehabilitating the water line as opposed to conventional replacement. Due to pressure on the line and the fact that the media flowing through the pipe was potable water, HS recommended the installation of the Primus Line Low Pressure Liner to rehabilitate the water line.
After careful review of the Primus Line product, Chemours engineers agreed that Primus Line was an excellent option for rehabilitating their pipe. Once the material was on hand and the proper excavations were made, HS cut the piping as necessary and using hydro flushing, HS cleared the pipe line of debris in preparation for the deployment of the Primus Line liners. Once cleared, HS video inspected the pipe using CCTV and deployed the Primus Line liners. The entire project took about (7) days from start to finish.
Chemours engineers were very pleased with the short time frame involved in the installation as well as the cost savings that were realized from the use of the Primus Line product as opposed to conventional excavation.
Our comprehensive approach to designing, building, maintaining and servicing mechanical systems makes us a preferred partner in the industry .Your company is dependent on systems and equipment to operate smoothly and efficiently, and we know it.
We offer complete coverage in professional pipelining maintenance and repairs. These services include:
