1, Material introduction:
Ultra-high molecular weight polyethylene (UHMWPE) is a new kind of engineering thermoplastics with more than 2.0 million viscosity-average molecular weight.
2, Production method of UHMWPE pipe:
UHMWPE wear resistant pipe is continually extruded by special extruders and specially designed moulds. Because of the ultra high molecular weight, the UHMWPE material is difficult to be extruded out, with higher requirements to the machines. But this point also make the UHMWPE pipe to be the wear resistant pipe.
3, Demension of the UHMWPE pipe:
Wall thickness: 5~50mm
4, Advantages of the UHMWPE pipe:
a. High Wear Resistance
High wear resistance is 4 to 7 times that of Q235 steel pipe and 2.7 times that of wear-resistant steel 16Mn.The working life of UHMWPE pipes is more than 3 times that of wear-resistant steel pipe.
b. High Corrosion Resistance
UHMWPE material structure is saturated molecular group, with great chemical stability,good resistance of various corrosion mediums(acid,alkali,salt)and organic solvents.
c. High Impact Resistance
Which is 5 times that of HDPE pipe, 2 times that of PC pipe and 10 times that of PTFE pipes. which makes UHMWPE pipe can withstand great water hammer impact when starting up pump station.
d. High Pressure Resistance
which is 2 times to that of PE100 pipe and 2.5 times to that of PE80.UHMWPE pipe can withstand wide fluctuate of water pressure in the pipeline.
e. Environment Proctection
The manufacturing and processing of wear resistant UHMWPE pipe is low carbon,without wasted water,exhausted gas and waste residue,which saves 20% energy compare with the traditional steel pipes.
f. High Flexibility
With high toughness and elongation of no less than 350%,the UHMWPE pipe and the connection site will not crack when crust settling which maximally ensure to supply water normally.
With toughness of 0.00022 and smooth pipe inner wall, it can efficiently avoid scaling without acid cleaning,which save a lot of maintenance cost.
h. Low energy consumption
Its coefficient of friction resistance is 0.009 while that of steel pipe is 0.013. With the same diameter, flow rate of UHMWPE pipe is large than steel pipe, and with the same flow rate,UHMWPE pipe can save 25% energy.
5, Application of the UHMWPE pipe:
1. Dredging Industry: Floating dredge pipe for river channel/sea shore/lake/pond, sand suction/slurry dredge
2. Mining industry: mine powder, mine slurry, mine tailings, mine waste rock delivery
3. Water Drainage: Sewage pipe
4. Sea engineering: Sea water desalinization, bunder dredgin
5. Chemical industry: mud and corrosive medium with slag delivery
6. Gas & Oil Industry: Crud oil,petroleum and natural gas transport
UHMWPE pipes have been widely used in Mine Tailings Discharge, Sand & Slurry Dredging, Chemical Industry, Gas & Oil field etc.
6, Matched products:
The hull of MDPE FLOATER is made from medium density polyethylene material with excellent flexibility, filled with high strength polyurethane foam inside. With reasonable structure and good performance, the MDPE floater becomes the ideal substitution of the traditional steel floater for the floating dredging pipes
Rubber pipe: Add the rubber pipe into the pipeline will help the whole pipeline increase the flexibilty
