UHMWPE Slurry Dredging Pipe
Introduction on UHMWPE Pipe :
Ultra-high molecular weight polyethylene (UHMWPE) is a new kind of engineering thermoplastics with more than 3 million viscosity-average molecular weight. Ultra-high molecular weight polyethylene pipe has superior performance over conventional HDPE pipe such as very high wear resistance, impact resistance, excellent resistance to internal pressure strength, resistance to environmental stress cracking, intrinsically self-lubricating, anti-adhesion, low temperature resistance and excellent chemical resistance.
Advantages of the UHMWPE slurry dredging pipe:
With a wear resistance 4 to 7 greater than Q235 Steel or 10 times that of HDPE (PE100) pipes under the same operating conditions, UHMWPE Pipe will give you far superior life under most operating conditions. UHMWPE is an inexpensive alternative to metals and ceramics
Because of its very smooth surface and self-lubricating properties, UHMWPE Pipe has far superior anti-scaling properties to any other pipeline on the market today. A non-stick factor that leads to its strength in the marine industry, preventing barnacle formation.
Lower Maintenance Costs, Less Maintenance Time, Less Downtime, Less Loss of Production
The far superior collaboration of wear resistance and weight reduction (0.93 SG) means the time between pipe replacements and/or rotations can be increased whilst simultaneously reducing installation management constraints of lifting gear and excavation requirements.
Reduced Pumping Costs
Along with the benefits mentioned above, UHMWPE Pipes also offer significant cost savings through increased pumping efficiency. With a surface roughness of 0.00022mm UHMWPE Pipe is extremely smooth and has resultant properties superior to PTFE (Teflon). Quantifying by example UHMWPE has a friction coefficient of 0.05, compared to 0.28 for HDPE or 0.58 for Steel (ISO 8295). This means less friction, less pressure loss and greatly reduced energy inputs to deliver the same result.
Lower Installation Costs
UHMW PE Pipe is connected by flanges and fastened by bolts and nuts.It has merits of quick connection,easy to dismantle,high strength,good tightness,etc.There is no need to do corrosion proof and rare trouble spots in the pipeline.It saves a lot of installation and maintenance cost and increases benefits.
Lower Maintenance Costs
The superior wear resistance enables the UHMWPE pipes to have longer service life than steel pipes, and effectively reduce the rollover times for the UHMWPE pipelines, which minimize the maintenance costs for the project.
