TeelBQ Americas and Tricon Piping Systems Partner for Bridge Installation of New Insulated PP-RCT Pipe System

TeelBQ Americas is excited to announce the successful installation of a new insulated version of its PP-RCT pipe in collaboration with Tricon Piping Systems of Syracuse, New York. As a result of the project’s success, the two companies will now partner to offer the insulated PP-RCT system to the market.

In spring 2020, Tricon installed 510 feet of the insulated pipe to the bottom of a bridge stretching over the Merrimack River in Tyngsborough, Massachusetts for use as a pressurized sewer line.

First, Tricon jacketed the 250mm (10-inch) TeelBQ PP-RCT with 14-inch HDPE pipe, filling the gap between the two pipes with foam insulation to prevent the line from freezing.

Tricon utilized a barge as a platform for a forklift, boom lift, and other equipment as it maneuvered the pipe and crew to the underside of the bridge for the installation.

Installing the PP-RCT system saved time, weight on the bridge, and money compared to what standard steel piping options would have required. The project involved no sweating or conventional steel welding, as fittings and 19-foot long joints were fused using electrofusion, a much faster joining process. The method involves melting pipe ends together to form a strong weld using electrically active wires.

In addition to making fusions easier, fewer overall were needed compared to steel pipe. Only two expansion joints were required for the project, one at either end of the line. Steel pipelines typically require more joints to be interspersed throughout the length of the pipe, but the three-layer construction of TeelBQ PP-RCT pipe includes a fiberglass reinforced inner layer that helps control thermal expansion and contraction and makes fewer expansion joints necessary.

Tricon and TeelBQ are now offering the insulated pipe system used for this project, the Tricon TeelBQ PP-RCT Pipe System, as a standard product to the market. The pipe system is ideal for sewer applications such as the Tyngsborough Bridge project, but also more broadly for process piping applications and use involving chilled water, hot water, and condenser water where it is more energy efficient.
