Casing Spacers Replaced
8” pipeline, X-52, double fusion bonded epoxy coating
Operating pressure 975 psi
Encased pipe under highway (HCA)
Replacement with new pipeline. Pipe had defect from original pull where spacers failed to say in place.
Existing pipeline was cut and pulled through casing for removal. Almost all of the existing casing spacers were broken, showed significant corrosion at bolts, and many failed to hold during pipe removal. Clock Spring were custom cut to 5 1/2″ widths and used as casing spacers to provide protection of girth welds and pipeline during installation.
57 units, spaced 12′ apart, were installed on new pipe sections in advance of installation. The crew of 10 installed all 57 units in 8 hours. Sections were then assembled on-site. Entire replacement of pipeline took approximately 4 days.
