Pre-Insulated Geothermal Pipes

The pre-insulated pipes are turned into one single piece at the production facilities of the company. The main carrier pipe PPr is produced at the extrusion lines. They are placed at the mass production lines. Axis pieces and leakage sensor wires are placed inside the pipe. PE pipe is slipped on the axis pieces. The openings are closed in order to fill the space between the inner carrier pipe and the outer case pipe with PUR. PUR is obtained through mixing 2 fluids called Polio and Isocyanides. These two fluids are mixed by a machine. They react to each other and puff up and because of the porous structure it gains, it prevents heat conduction. After the PUR filled between the pipes solidifies, the pipe is ready for use. When steel pipe is used instead of PPr, it is outsourced and it is similarly processed like the PPr for the production of the pipe. The fittings of the product are manually produced without a requirement of facility. Carrier pipe is produced via injection or fabrication method and is placed inside. Outstanding Features Since the case pipe is produced from Polyethylene, it is highly resistant to corrosion." The humidity over and underground doesnt affect the insulation material." The service life of insulation is 30 years against external factors." With the corona system there are chemical bonds forming between the Polyurethane and the case pipe. Therefore, they behave together in terms of expansion and the effect of the elongation of the carrier pipe to the insulation is prevented." The Polyurethane that is used has the certificate conforming to EN 253 standard." The pipe can be used for the transportation of fluids up to 140
