Products and services. The Company engineers, designs, manufactures and sells specialty piping systems, and leak detection systems. Specialty piping systems include: (i) insulated and jacketed district heating and cooling ("DHC") piping systems for efficient energy distribution from central energy plants to multiple locations, (ii) primary and secondary containment piping systems for transporting chemicals, hazardous fluids and petroleum products, and (iii) the coating and/or insulation of oil and gas gathering and transmission pipelines. The Company's leak detection systems are sold with its piping systems or on a stand-alone basis, to monitor areas where fluid intrusion may contaminate the environment, endanger personal safety, cause a fire hazard, impair essential services or damage equipment or property.
The Company frequently engineers and custom fabricates to job site dimensions and incorporates provisions for thermal expansion due to cycling temperatures. This custom fabrication helps to minimize the amount of field labor required by the installation contractor. Most of the Company's piping systems are produced for underground installations and, therefore, require trenching, which is the responsibility of the general contractor, and completed by unaffiliated installation contractors.
