large diameter HDPE pipe for submersible sand dredging pump
Junxing HDPE dredging pipes have unique features for a long term,corrosion free abrastion resistant and low maintenance in the seas,lakes and all other water liquids.Our HDPE dredging pipe are fitted with welded stub-ends&steel flanges. And floats are available together.
HDPE Dredging Pipe Application:
1. Transport sad and dirty water from the river.
2. Used to conveyor mud and from the pond
3. Used in to deliver slurry, mud, sad etc in dredging projects
HDPE Dredging Pipe Properties:
Specific Gravity, g/cm3, 20(C): 0.941-0.965
Longitudinal Reversion, % (110(C)): <=3
Oxidation Induction Time, min (200(C)): >=20
Extension Rate at Break. %: >=350
Hydraulic Pressure Test:
20(C), Hoop Stress is 12.4Mpa, 100h: No Failure.
80(C), Hoop Stress is 5.5Mpa, 165h: No Failure.
80(C), Hoop Stress is 5.0Mpa, 1000h: No Failure
HDPE Dredging Pipe Performance:
1..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.
2.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.
3.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.
4.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.
5.HDPE Sand Delivery Pipe is either on land or water for using, total engineering cost is low, high efficiency, safer, and more convenient.
