UHMW-PE Pipe Features: 1 high impact resistance UHMWPE impact resistance and absorb impact energy in the first ranks of plastic, whether it is strong external shocks or internal pressure fluctuations are difficult to make it crack. The impact strength of nylon 66 of 10 times, 20 times of PVC, polyethylene, 4 times. Especially at low temperatures, but higher impact strength values. This ultra-high molecular weight polyethylene flexible conveyor system provides for the safe and reliable protection. (2) high wear resistance in many piping materials, ultra-high molecular weight polyethylene smallest friction coefficient, combined with ultra-high molecular chain particularly long, so the wear resistance of ultra high molecular weight polyethylene pipe than when in transport all kinds of slurry steel pipe, stainless steel tube 4-7 times higher than the PVC pipe and polyethylene pipe about 10 times higher, substantially increased the life of the pipeline. 3 based on ultra high molecular weight polyethylene corrosion resistance is a structure of saturated molecules, so its high chemical stability. In a certain range of temperature and concentration ability of various highly corrosive media (acids, bases, salts) and organic solvents erosion. 4 no scaling UHMWPE self-lubricating and non-adhesion, friction coefficient minimum. Special process produces pipe wall corrosion resistance, abrasion resistance, no scaling, so the flow resistance is small, can be maintained long-term velocity and flow unabated. Designed to reduce the inner diameter of 15.4% than steel. 5 weathering and aging resistance Our company produces black modified ultrahigh molecular weight polyethylene pipe has good weathering and aging resistance. On the one hand, because the high molecular chain pipeline chain unsaturated molecules little molecular weight; other hand, adding a special modifier, so high greatly exceeds the normal life of the pipeline polyethylene pipes. Using 60 years or so, still maintain high pipeline more than 70% of the mechanical properties. 6 width can be long at optimum temperature to 80 ℃ -269 ℃ operating temperatures. 7 for fire retardant special industry environment, adding flame retardant modification, special machining process, overcoming UHMWPE itself flammability, flame retardant. 8, light weight, easy installation, good flexibility of the product.

High molecular weight polyethylene pipe as industrial pipes, the following five main application areas. 1, oilfield oil well pipes and pipeline pumping wells currently in service with more than 120,000 population, the depth is generally between 500 m - 3000 m, with an average depth of 1,500 meters, according to projections, each well requiring ultra-high molecular weight polyethylene lined composite pipe about 1 ton, if a 10% annual wells with high wear resistance, high corrosion-resistant composite OCTG, then the annual UHMWPE lined pipe demand will reach 12,000 tons. According to the information in PetroChina, Sinopec, the two groups, the internal oil pipeline 104,123 km, due to its much larger than the average diameter of the pipe OCTG requires high temperature, high wear resistance, high corrosion-resistant lining pipe amount more large. 2, CWS pipeline, according to the information reported to the end of 2004, China had more than 20 coal slurry plant, with a total designed capacity of approximately 500 tons / year, the largest coal slurry plant 1 million tons / year. China since the early 1980s to begin planning the 10 coal pipes of different lengths, including Bangladesh - Wei pipes up to 600km. In addition there are 10 million tons per year of coal preparation plant byproducts - Slime needs through the pipeline. Using ultra high molecular weight polyethylene lined composite pipe, which can effectively avoid anti-viscosity liquid mixture produced this high wear and corrosion, and because of its self-lubricating and reduce transport resistance, greatly reduce power consumption. In 1998, China's energy industry to develop long-term development plan outline clearly pointed out: "To develop pipeline transporting coal, coal slurry transportation," coal pipeline transportation of coal is the current lack of capacity to solve our major mode of transport. 3, power plants and hydro power plant fly ash conveying system, the prevalence of tube wall fouling problems. Entrance 100m range scaling, corrosion is more serious. Ash tube in addition to scaling, the wear and tear is more serious, straight pipe mill in just two years there will be leakage phenomenon, elbow position is more prominent. Ultrahigh molecular weight polyethylene (UHMWPE) composite pipe liner anti-adhesion, easy to hang gray scaling phenomenon can be reduced, even if there is some degree of fouling, is relatively easy to remove, and the pipe resistance, wear resistance corrosion, which can greatly extend the service life, and does not require paint anti-corrosion coatings, thereby saving maintenance costs. There have been volumes with UHMWPE sheet liner made of a test, the results showed that the basic scaling, its wear resistance than ordinary steel increased by 8 times. China's existing large coal-fired power plants of more than 400 seats, small power plants more in the future will be an annual rate of more than 10 additional power plants. For each plant ultrahigh molecular weight polyethylene pipe 100t, the country would need a few tons. 4, river sediment transport tube according to statistics, China's annual average sedimentation rate of the Yellow River has 400 million tons. Dredging governance task is very arduous. Similarly, China's other inland rivers and estuaries are dredging governance need to be implemented. Under normal circumstances, every ship of sediment dredging vessels to be equipped with 4km pipeline. Steel is easy due to corrosion, wear fast, heavy, and difficult handling, with ultra high molecular weight polyethylene liner to replace the traditional steel composite pipe is the general trend. Dredger over 1000 of our existing fleet, if all coupled with ultra-high molecular weight polyethylene (UHMWPE) lined composite pipe, which demand is relatively large. 5, the material pneumatic conveying fertilizer, grain and other materials requires the use of pneumatic conveying equipment to transport the unloader. China's coastal port of unloading imported grain in bulk grain berth equipped with pneumatic grain machines, handling machines and silos, the majority of small and medium-grain port berths are equipped with fixed suction grain machine, need to wear appropriate pipeline. To 2004 shipments of bulk cement has reached more than 320 million t of grain in bulk shipments there are more than 60 million t. With strong wear resistance, ultra high molecular weight polyethylene lined composite pipe in the bulk material transport also has broad application prospects. 6, mining mineral processing, metallurgy coal, chemicals, iron ore, non-ferrous metal ores and non-metallic mineral mining, concentrator slurry transportation extensive use of pipes, tubes, such as ore, tailings pipe, concentrate pipe, tube flotation system and so on. According to Japanese statistics, transporting ore slurry pipe service life 15000h, when the original tailings pipe shortest 6000h, mortar tubes filled with mostly 6000h, the longest time for the 1000h. At present, China concentrator tailings, concentrates mostly conveying pipe steel pipe, because the pulp contains about 30% of the iron ore, steel pipe wear quite severe, life is only 1 ~ 2a, and every six months to turn 90 °, the heavy workload. Metallurgical industry, coke powder, slag, pulp and smelting slag processing also involves a lot of pipelines. If a steel company in a selection of various mineral concentrator for conveying piping up to 60km, the worst parts for wear and tear usually need to be replaced once a pipeline of several weeks, the rest intervals not long pipeline on the need to flip, workload can be imagined. Our country is coal mining country, over 90,000 mines up. According to incomplete statistics, the annual need to wear mine with plastic tube about 20,000 t, if widely used, the annual demand for 40,000 t or more, can save steel 200 000 t. According to reports, the U.S. Federal Environmental Protection Commission requires mining industry, especially the ore draining operation to ultra-high molecular weight polyethylene pipe. Ultra-high molecular weight polyethylene pipe is also widely used in: food, feed processing industry; oils, wine industry; food and pharmaceutical industry; textile, chemical industry; building materials, bulk materials transport; chemical industry; sea lake salt chemical industry; treatment; Pharmaceuticals Industrial; gas industry; seawater utilization, shipbuilding; refrigeration technology and cryogenic engineering and other fields.
