1 PPR PIPELINE WELDING TOOLS

2 AQUART always with you! AQUART PPR pipes and fittings are well known on the pipeline market for more than 15 years already. China and Indonesia, Russia and former Soviet countries, North Africa and Gulf states, India and Pakistan, Turkey and Bulgaria are familiar with AQUART as with a high quality trading group. AQUART applies exceptionally the best modern thermoplastic equipments and raw materials of such approved trade marks as BOREALIS, HOSTALEN,SAMSUNG, HUSSONG, SINAPEC. AQUART PPR pipes and fittings are produced in different countries that makes them easy for our customers to buy, and provides the highest quality at the most convenient price. Thus, all PPR fittings are produced in China, Ningbo; all pipes go from China, Russia, Germany, Turkey, Poland. AQUART GROUP constantly develops the range of goods and offers its customers new products. In this catalogue you can find new types of PPR pipes: copper (PPR - CP) and stainless steel (PPR SS) pipes in PPR covering; composite PPR pipes with fiber glass middle layer (PPR FB PPR); and new reinforced pipes (PPR AL PPR) which do nor require fettling. This catalogue also includes new-type PPR fittings: filtrate valves, elbows with plaster clamp, a variety of PPR valves, and others. In the year 2006 our system of product distribution has changed. For our wholesale customers we have opened a new office and a show-room in Shanghai, so it has become possible to buy our products directly at the plant. Our retail customers can still buy AQUART goods through AQUART Trading System and via Internet shop

7 MOUNTING PROCEDURE The main method of jointing polypropylene elements is the spigot-and-faucet welding. For jointing PPRC piping systems with metal components, combined fittings with embedded threaded parts, couplings with nuts, or flanges are used. In case of joining with the help of couplings with nuts and flanges, plastic faucet with shoulder should be welded to the pipe. You can use hacksaw or other sharp instrument to cut pipe segments, but it is more preferable to apply special scissors and cutters. For different pipe diameters special types of these tools developed. The cut off should be made at right angle strictly, the contortion is inadmissible. The contortion of the pipe means that your instrument is not sharp enough. You should clear burrs off the sheared edges, you may use the cuter or the knife. Spigot-and-faucet welding The welded parts should be prepared carefully. It is strongly recommended to cut off the both ends of the pipes at angle C, especially when pipes with diameter 40 mm and more are used. It is also advisable to scrape off the edge outer layer for about 0.1 mm at the jointing places of the pipes with big diameters. Damaged and cracked pipes can not to be used. If the pipe and the fitting can be joined easily when not heated, they should not be used. The common rule for spigot-and-faucet jointing is that the inner diameter of the unheated faucet part should be just a little smaller than the outer diameter of the pipe. The same rule concerns the welding adaptors as well: they should not fix easily with the welded parts in cool state; in the process of welding the adaptor and the welded component should be closely connected. The parts that do not meet the requirements can not be used! Welding parts should be cleaned in the joint area from any kind of dirt and degreased with the help of spirit or specific cleaner. Mark the depth of welding according to the table bellow. Remove metal layer from the reinforced pipe with the help of grinding instrument. You may heat the pipe with the drier to remove the aluminum layer easier. Diameter of the pipe, mm Welding depth, mm Heating time, sec Welding time, sec Cooling time, min Table 2. Welding depth and processing time at ambient temperature 20 С Fix the welding dies of proper diameters the bushing and the draw bar on the welding machine. Switched to the power supply socket machine warms up to essential working temperature (260 o C) automatically. You can settle the heat regulator on the desired temperature if necessary. Welding itself is the jointing of two parts when they are already heated in the machine. Put the pipe into the heating bushing and the spigot part on the draw bar. The process should be done smoothly; radial rotation is prohibited. Pipe axis line should not deviate from the bushing axis line by more than 5 degrees.

8 MOUNTING PROCEDURE For welding pipes with big diameters (more than 40 mm) and length above 2 meters, apply specific welding device with centrator to gain coaxiality of the jointing. After the stipulated heating time remove the welded parts and join them immediately. Push the pipe into the faucet up to the end of the welded area. Do not turn the jointing and keep the coaxiality of the parts. Note: a pipe pushed too deep into the faucet can trample and reduce the inner section. As a result of overheating, the pipe diameter may become too narrow, and the fitting diameter may increase. It is recommended to keep the parts fixed strongly for about welding time. Do not align the parts or use cold water during the cooling time. After the cooling time the jointing may be used under moderate mechanical stress. The piping system may be filled with water in 1 hour after welding. A well-done jointing may have the axial deviation of the pipe and fitting below 5 C. There should not be cracks, or folds, or other damages caused by overheating on the faucet part; there should be even all-round bead of welded plastic material around joint. Polypropylene pipes welding should be held at ambient temperature 0 C or higher. Prevent welded connection from dust and atmospheric precipitates. The ambient temperature during the mounting is very important. You should increase the welding time in cold conditions (up to 50% when the temperature is about 5 C) and decrease the time when it is hot. Consider also the cooldown of the surface of the welding machine. It is the best to use heat signal light to make sure that the welding surface temperature has reached 260±5 С. Welding dies and welding machine should be kept clean. Remove the left over material with the help of rough napkin, avoid damaging of teflon surface of welding dies. Pic. 6. Basic operations of butt fusion: cutting, heating, connecting. THERMAL INSULATION Thermal insulation should be installed on the heating systems, laid in non-heated buildings; in the place s of possible freezing of the heater; in artificially cooled rooms; for the purpose of preventing scalds and condensation. Polypropylene material has rather low thermal conductivity, thus PPRC pipes require less insulation material than metal pipes. For example, PN20 pipe will have 53 С surface temperature as a result of transporting water at temperature 80 С for a continuous time.
