TPEP corrosion pipe (outside 3PE within FBE composite pipe) and the traditional comparison of pipeline transporting water pipes using pipe economic and technical comparison? Piping design, according to the technical and economic characteristics of pipes and geological, topographical conditions appropriate to choose the best pipe in order to ensure the suitability of water engineering and economics. Note: What is TPEP TPEP anti-corrosion steel pipe, also known as external corrosion 3PE within FBE composite pipe (T is a Triple, said that three times, three of three parts, in this case three, PE, PE, EP? hot melt bonded epoxy powder) refers to a specific external 3PE preservative is within FBE composite pipe corrosion. ◆ hydraulic Comparison For comparison, we will all pipe roughly divided into two categories, the first category pipe for cement pressure pipes, cement mortar lining corrosion ductile iron pipe, the second pipe of thermosetting plastic, thermoplastic pipe and steel-plastic composite pipe, the first class of pipe roughness coefficient close n1 = 0.013, the second type of pipe n2 = 0.009. When the selected pipe is not the same, there is a big difference between the hydraulic conditions. Therefore, the water delivery pipe selection process, and taking into account the factors. Same diameter, the same flow, hydraulic losses plastic composite pipe, ductile iron pipe and comparison table below. Hydraulic comparison Conclusion: plastic composite pipe, ductile iron pipe head loss than saving 48%, reduce the use of plastic composite pipe lift, pump and motor power and electricity have been saved, significantly reduce operating costs ◆ relatively ductile iron pipe diameters: flow rate Q = 1836m3 / h velocity v = 1.01m / s, 1000i = 1.51 cast iron pipe found by "supply and drainage design manual," the first book in Table 11-11 DN800 plastic composite pipe diameter selection: Flow Q = 1836m3 / h 1000i = 1.51 was calculated dj = 700mm choice of plastic composite pipe DN700mm. Compare diameter Conclusion: Under the same volume and flow conditions using ductile iron pipe DN800 caliber plastic composite pipe DN700 chosen to meet the requirements. ◆ prices relatively large diameter (≥DN700) plastic composite pipe is lower than the ductile pipe prices. The larger the diameter, the lower the price of plastic composite pipe, the price advantage is more obvious. ◆ river, aisle, crossing, water hammer effect, uneven ground subsidence, only steel-plastic composite pipe. To sum up: TPEP plastic composite pipe corrosion and mechanical properties not only much larger than ductile iron pipes, plastic pipes, steel pipes, etc., and make the project investment costs and operating costs are significantly reduced, especially long-distance transmission, so steel plastic composite pipe with a high price, because a large project is now widely used.
