HDPE Sand Delivery Pipe is most suitable for mud & sand delivery and discharge, the performance is as follows:1. HDPE Sand Delivery Pipe of weight is light, only one-eighth of steel pipe, Through activities flange bolts to connect, installation and dismantle, transportation are convenient, shorten the time, improve efficiency, so as to avoid the pipeline welding together to repair and replacement pipe time-consuming faults after external damage.2. HDPE Sand Delivery Pipe has good flexibility, tensile strength and elastic, pipe extrusion, pack, it doesn't break after internal and external force impact, Plastic pipe can be directly connected, in the water it can bend, 4-8 pieces can bend 360 degrees. Good resistance of stormy waves, On land of connection, the concave-convex is within 30 degrees of area, can be connected directly, it does not need to repair ground of surface.3. HDPE Sand Delivery Pipe has good wear-resistance, it is 4-8 times of steel pipe, use longer, Piping material of corrosion resistance is strong, can soak in sea water for 50 years with no change, Anti-uv, anti-aging, and it can be used for 5-8 years upon sand content.4. HDPE Sand Delivery Pipe is assembled with two metal activity flanges at both pipe ends. The entire pipe is without any weld, pipe and pipe are connected by flanges of bolt., Steel pipe lining, can ensure pipe will not deformation and drip when installation and disassembly, ensure transportation engineering of high efficiency.5. HDPE Sand Delivery Pipe has smooth outer and inner wall, friction coefficient is tiny, high transmission efficiency than steel pipe 20% to 30%, temperature is used at - 40-60 ° c, can adapt to bad weather changes in temperature.6. HDPE Sand Delivery Pipe is either on land or water for using, total engineering cost is low, high efficiency, safer, and more convenient.HDPE pipe types: SDR33, SDR26, SDR21, SDR17, SDR13.6, SDR11
