Piping Solutions for HVAC

Georg Fischer Piping Systems offers Piping Solutions for HVAC applications. These have many useful features enumerated below. Corrosion resistance: plastics are not conductive and are therefore immune to galvanic or electrolytic erosion. Because plastics are corrosion resistant, plastic pipe can be buried in acidic, alkaline, wet or dry soils and protective coatings are not required. Low thermal conductivity: all plastic piping materials have low thermal conductance properties. This feature maintains more uniform temperatures when transporting fluids in plastic than in metal piping. Low thermal conductivity of the wall of plastic piping reduces greatly the thickness for pipe insulation to control sweating. Flexibility: in general, thermoplastic piping is relatively flexible as compared to metal piping. This facilitates use of efficient installation techniques. Some of the more flexible materials allow for coiling, which permits long pipe runs with a minimum number of joints. Low friction loss: because the interior surface of plastic piping is generally very smooth, less power may be required to transmit fluids in plastic piping compared with other piping systems. Furthermore, the excellent corrosion resistance of plastics means that the low friction loss characteristic will not change overtime. Long term performance: owing to the relative chemical inertness and the minimal effects of internal and external corrosion, there is very little change in the physical characteristics of plastic piping over dozens of years. Variety of joining methods: plastic piping can be joined by numerous methods. For each material there are several appropriate methods. Some of the most common are solvent cementing, heat fusion, threaded joints, flanges, O-rings, rolled grooves, and mechanical compression joints. This variety of joining methods allows plastic piping to be adapted easily to most field conditions.
