Welded steel pipes are widely used and are one of the most common pipes used in power systems. Its advantages are high pressure resistance, high strength, the most safe and reliable for projects with good water quality, but the welding workload is large, the corrosion protection workload is large, and the pipeline is heavy. Steel sleeve concrete pipe is also a kind of water conveying pipe, and its connection interface mostly uses socket type rubber ring interface. It is difficult to guarantee the quality of the socket interface. Damaged at the socket. The wonton soil pipe is not resistant to acid and alkali, and its weight is large. If the DN60 steel sleeve concrete pipe is used, the weight per meter of the pipe is about Zt. It is inconvenient to install and transport. In addition, metal fittings should be used when turning, branching, and reducing the diameter of the pipeline, and it is necessary to design stick-concrete town piers and make concrete pipe supports at the sockets. When the geological conditions are poor, it is necessary to make a concrete pipe strip foundation. This situation often causes the pipeline itself to be low in cost and the overall cost is high. PE pipe PE pipe has excellent characteristics such as good toughness, twist resistance, shock resistance, wear resistance and impact resistance. The interface adopts hot-melt butt fusion and electric fusion butt. Shixian has a continental semi-dry early climate. Ten years and nine early, the water resources are seriously insufficient, and agricultural water accounts for more than 85% of the total water consumption. The traditional farmland canal irrigation method has serious losses in water transmission and leakage. Field irrigation generally wastes a lot of water, seepage, and leakage. The effective utilization rate of water is only 60p%.
In addition, PE pipe is a kind of high-toughness pipe. Its elongation at break generally exceeds 50%. It has a strong adaptability to the uneven settlement of the pipe base and has good seismic performance. The absolute roughness K value of the inner wall of the PE pipe does not exceed 0.01rnm, while the K value of the new steel pipe and ductile iron pipe ". 06mm, the inner wall adopts enhanced anti-corrosion and the K value is greater. The absolute roughness K value of the inner wall of the PE pipe will not change with time, and has good water flow and hydraulic conditions. The pipeline resistance of the PE pipe when transporting water is small. According to national standards, the maximum diameter of PE pipe can be produced to 1000mm. The pipe is light in weight.
We are a manufaturer of Scouring Pad that we can sell the in roll directly. A lot of clients will buy the clothes and then process other cleaning products.
