P.V. Prefabet Kluczbork, as the first producer in Poland, offers egg-shaped pipes in concrete and reinforced concrete versions. The egg shape of the pipe guarantees, even with low filling of the sewer, high speed of flow and ensures a lot of space in the event of seasonal increase of the amount of wastewater. At the proper lengthwise elongated slope of the collector and even with low filling, the speed of flow will not drop below the speed of hydraulic cleaning of the conduit.

We offer egg-shape pipes with footing, guaranteeing easy assembly in the trench and stable functioning in extended periods of time. Pipes are equipped with gaskets integrated in the flare. Each pipe has pre-installed transportation hooks, which help in unloading of the pipes and their placing in the trench. Besides standard classes of concrete, that is C40/50, we also offer pipes manufactured from high-durability concretes (e.g. C 70/85), based on sulphate-resistant cement and with Preco® type polyurethane linings or PEHD (high-density polyurethane). Egg-shape pipes manufactured by P.V. Prefabet Kluczbork are cured in stationary moulds, thanks to which their surface is extremely smooth and dimensional tolerances very low. For all egg-shape pipes we offer well-known and proven sewerage chambers type P.V. with leak-proof connections.

Advantages of the solution

• optimum flow speed, guaranteeing self-cleaning of the sewer;
• intelligent solution for sewers periodically transporting large volumes of wastewater;
• the possibility of not only selecting the proper material and structural protection (concrete class, cements with increased resistance to sulphates), but also surface protection (plastic lining);
• flexible system consisting of pipes and chambers with leak-proof connections, which make possible optimum customisation to the specific needs of each project.
