Yorktown Terminal Pier

US Pipelining recently completed a CIPP project at the Plains All American Yorktown Terminal.

US Pipelining LLC., recently completed a major cured-in-place pipe (CIPP) relining project Plains All American Pipeline’s Yorktown Terminal in Yorktown, Virginia.

The CIPP liner was installed utilizing air inversion into a 12-in. diameter concrete lined steel sump line located on a pier and extending nearly a half mile over the York River. According to the Langhorne, Pennsylvania-based contractor, it is believed to be the longest single-shot, one-piece, CIPP liner ever installed.

“It is our understanding that this is the longest air-inverted, one-piece CIPP liner that has ever gone in a pipe, and the longest ever to breach a waterway,” said Jeremy Bowman, field project manager for US Pipelining, the project’s lead contractor. “Air was used for the liner inversion and steam was the method of cure. Water inversion was not an option as the process water presented an issue given the pipes location above an active waterway. This was one for the record books.”

Access for construction was created by removing spool sections from the host pipe where the pipe system meets the shoreline. Additional spool sections were removed at the far end of the pipe which extended out 2,500 ft over the York River. The construction and cure of the CIPP would take nearly 24 hours.

The CIPP liner was manufactured to meet project specifications by Manufactured Technologies Corp (MTC) of Chesterfield, Missouri. The custom-made liner was the longest MTC had ever produced. The resin impregnation (wet-out) was performed at the MTC facility in Olyphant, Pennsylvania.

“This was an extremely technical project,” said Mark Wetzel, senior director of MTC. “Installing a liner of this length requires in-depth planning and technical experience. The conditions have to be perfect, the obstacles mitigated. Hats off to US Pipelining.”
