Dizayn - Heating and Geothermal Pipes and Fittings

Prior isolated pipes are made compact in the company production field. PPr pipe is produced on extrusion tracks as the main carrier pipe. Placed on the serial production track. Axing parts and leakage sensor wires are placed over pipe. PE pipe is swiped over the axing parts. Nozzles are closed to insert PUR in the region between internal carrier pipe and external casing. PUR is inserted form the hole over the pipe nozzles. PUR is obtained by the mixture of two liquids called Poliol and isocyanate. The two fluid is mixed with machine and pushed out. Two product make a reaction and start to blister and has a structure which does not transfer heat by its cellular structure. After PUR inserted in between the pipe solidifies, pipe is ready for usage. If steel pipe is being used instead of PPr it is provided from outside and the pipe is produced by applying the operation applied to PPr.

The fittings of the product is produced manually without necessity of plant. The carrier pipe is produced by injection or confection method and placed inside the product.

• The casing pipe being Polyethylene show high resistance for corrosion.
• The humid on the ground and underground does not effect the isolation material.
• Isolation life time against external factırs are 30 years.
• By the corona operation applied as the polyurethane casing maked a chemical reaction with pipe it is moved integrally on thermal expansion and the effects of elongation of carrier pipe on isolation is prevented.
• By the integral structure steel pipe elongation is prevented by earth rubbing forces.
• The polyurethane used has certificate in conformity with EN 253 norm.
• The pipe can be applied up to fluid transfer at 140°C.
• Steel, PPr, copper can be used as main carrier pipe. If required production can be made as the inside of the pipe is covered (such as epoxy). Sewed, non sewed steel can be preferred.
• Prestressed system is obtained if the carrier pipe is heated before being furnished and its earth filling is made. Thus the elongation effect is removed as much as the heated temperature. As the total elongation values decrease, there is no necessity of using compensator.
• All kinds of isolation pipes and attachments are available. (Bend, TE, Valve etc.)
• Retention and distortion of isolation is removed by the sliding casing system used on attachment.
• On prestressed systems as the L, Z, U bends are not being used, there is no necessity for channel expansion forthe furnishing of these parts.
• As the isolation and the casing pipe pf the product is made in the factory environment conditions of buildig site, quality problems, teh length montage period is not in subject.
• It does not require cobstruction structures for opening gallery underground, to carry on hanger. Problems composed by the water filling of the channel are not in subject.
• Production is made in accordance with the international standards (EN 253).
• It has international certificates (GEF).
• It is used in the transfer of waste heating on regional heating, geothermal energy applications, cogeneration systems.
