Natural Gas Pipeline Replacement Near State College PA

Allegheny started a $1.7 million project to update 5,000 feet of four- and six-inch 1940s-era bare steel natural gas pipeline near the main campus of Penn State University. The lines parallel a section of Atherton Street, a roadway traveled by more than 38,000 vehicles a day during peak traffic periods, according to Pennsylvania DOT statistics.

Allegheny is placing on average 250 feet of line per day. The new six-inch diameter medium density plastic pipeline is being installed in a manner that minimizes service disruptions to homes and businesses. Sections are fused above ground to length using McElroy 28 fusion machines, lowered into place on top of 4 inches of limestone sand and backfilled with sand bedding followed by crushed stone. Allegheny is utilizing trench shoring equipment manufactured by Kundel to protect employees from trench collapse.
