EA Services provides sprayed-in-place-pipe to American Airlines
In June 2011, American Airlines’ Tulsa Engineering Facility personnel discovered a severe leak in their fire suppression system following a recent activation. The section of damaged pipeline was approximately 70 feet long and was situated 8 feet below a power substation, and encompassed one 10-inch tee. Dig and replace was not a viable option.
American Airlines learned of Sprayed-in-Place-Pipe (SIPP) technology from EA Services’ website (www.pipeliningusa.com). SIPP is a new trenchless robotic lining process designed by engineers at Inspar for the rehabilitation of in-place or “insitu” pipelines. SIPP repairs meet or exceed the pipe’s original design parameters. SIPP saves time and money in corrosion and replacement costs, and is environmentally friendly.
After water jet cleaning of the pipeline, EA Services and Inspar technicians initiated and completed a camera inspection that identified several perforations ranging in diameters from 0.25 to 0.375 inches. The technicians robotically lined the deteriorated pipe section with 0.25 inch of StructrLine SS. StructrLine SS is a semi-structural severe service lining system specially formulated by Inspar scientists for the remediation of partially deteriorated pipelines including steel, concrete and plastic. It offers exceptional chemical, abrasion, impact and extreme tear resistance and can withstand temperatures of 400 degrees Fahrenheit or greater in dry applications and up to 350 degrees Fahrenheit in various chemical and aggressive environments. In addition, the product’s quick cure time enables a rapid return to service.
The turnkey project to rehabilitate this carbon steel pipe was completed in two working days and just one week after the initial contact from the customer.
