The system made of PVC-U pipes and fittings is in accordance with international standards for the transport of drinking water through plastic pipes.
Both PVC pipes and fittings have a high chemical resistance to most aqueous solutions, to the aggressive action of materials in the soil, salts and caustic substances or aqueous acid solutions. Thus, PVC-U pipes and fittings can be used for the transport of basic or acidic aqueous solutions, mineral salts, etc. with pH between 2 and 12, and working temperatures of max. 60°C.
The remarkable hydraulic characteristics of the PVC pipe and fitting systems are determined by the possibility of producing interior walls with an extremely low roughness (<0.01mm), 10 times lower compared to pipes made of materials other than plastic. Thus the flow rates and flows are higher than with steel pipes, and the pressure losses are reduced to a minimum.
Manoeuvrability and installation
The low weight of the components of the PVC pipe and fitting systems ensures an extremely high manoeuvrability in terms of transport, storage and handling, as well as installation. Installation is extremely simple, because the components are joined by gluing with adhesive.
Fields of application of pressure PVC-U pipes and fittings
• drinking water distribution networks for domestic and industrial consumers;
• irrigation networks and water management;
• transport of industrial liquids.
Transport, handling, storage
For transporting pipes, the vehicles used must have platforms free of nails or other metal protrusions which may damage the pipes. Securely fasten the pipes before transporting them. When loading pipes with a plug, the pipes will be stacked so that the plugs are in contact with the adjacent pipes.
When handling pipes and fittings, avoid damaging them. Plastic products can be damaged when they come in contact with sharp objects or if they fall, are thrown or dragged on the ground. Do not drop or throw products and pallets under no circumstances. The impact resistance of plastic products is reduced at very low temperatures and in such conditions extra care must be taken during handling to avoid any impact with sharp objects when handling, loading or unloading. We recommend paying special attention to the handling of pipes and fittings if the temperature is below -5°C.
When storing pipes and fittings on site, the contractor must provide an adequate space for their storage. Bulk or pallet PVC pipes must be stored on flat surfaces, without sharp objects (stones or protrusions). The fittings should be kept in their original packaging as much as possible. If there is no covered space, they can be kept outside. In the case of keeping the pipes in pallets, they can be stacked, but not more than 3 pallets - for pipes with a diameter of 110-200mm and a maximum of 2 pallets in the case of pipes with a diameter of D250-400mm. In both situations, safety measures must be taken to prevent sideway movements or the possibility of their collapse in case of wind gusts. When storing bulk pipes, the stack height must not exceed 1.5 m. In this situation, the pipes must be placed on wooden supports with a width of at least 7.5 cm, positioned at a distance of 1-2 m. The supports at the stack ends must be positioned at a distance of 0.5, maximum 1m from the pipe end. Smaller diameter pipes can be telescoped into larger diameter pipes, as long as the pipes are provided with supports along their entire length. In case of storage for a longer period (over 6 months), it is recommended to protect the pipes from solar radiation, avoiding to block their ventilation, and to remove the pipe gaskets and keep them in a space away from strong solar radiation and high temperatures.
