Company: Shandong Buoy&Pipe Industry Co., Ltd.
Business type: Manufacturer
Shandong Buoy & Pipe Industry Co., Ltd. is a technology leader specializing in research and
manufacturing of UHMWPE (ultra high molecular weight polythene) products--UHMWPE pipes, UHMWPE Navigation Buoys and UHMWPE Light Houses.
What is Ultra High Molecular Weight Polyethylene?
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.
UHMWPE Pipes Advantages:
Longer Life
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.
Non-Scaling
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.
Chemical and Corrosion Resistance
With chemical resistance second only to PTFE (Teflon), UHMWPE pipe will offer superior life to other pipeline products in acidic or corrosive applications under 85 degrees C.
Key Applications:
- UHMWPE pipe for dredging
- Slurry pipe
- Tailings pipe
- Coal mine pipe
- Wear resistance pipe
- Mud & sand dredging pipe
-
Pipe for municipal sewage sludge dredging
