Pre-Insulated Geothermal Pipes, 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°C." For the main carrier pipe PPr and Steel can be purely used. When demanded, inner surface of the pipe can be covered in production. Steel with or without seam may be preferred. " If the carrier pipe is heated initially and filled with soil then Pre-tension system will be achieved. Therefore, elongation factor for the heated temperature is eliminated. Since the total amount of elongation is decreased, there is no need of using compensator." Any type of insulation pipes and fitting are available. (Elbow, TE, valve etc.) " With the aid of the sliding case system at joints leakage at connection points and damage on insulation are prevented." In pre-tension systems since L, Z, U bands are not used canal enlargement for these pieces is not required." The insulation and case of the product is accomplished in factory environment. Therefore, quality problems concerning the site conditions and long installation time are not a matter of article." The product doesnt need construction equipment for opening a gallery underground and for carrying on hangers." Production conforms to international standards (EN 253)" It has international certificates (GEF)" They are used for the transfer of waste heat in cogeneration systems in geothermal energy applications and district heating.
