1. Brooklyn Union Gas Co., NY (United States)

Innovative use of a new HDPE lining technology recently saved Brooklyn Union Gas Co. 30% over conventional replacement costs. The company chose lining technology from United Pipeline Systems called Tite Liner to rehabilitate 2,500 ft of 20-in., 15 psig, bare steel main in Brooklyn's Bay Ridge section, an area spanning six city blocks and crossing three major avenues. The main is mechanically joined with no offsets or service connections. Due to surface and subsurface working space restrictions and the impact on costs, the company elected to employ the liner system in which a specially designed HDPE liner pipe is reduced to a smaller diameter through a rolldown box for insertion into a steel or cast iron main. A tight fit is attained as the liner is allowed to expand against the pipe wall after pull through.
