Shandong-Buoy - UHMWPE Water Pipe

No Leakage

The traditional water supply and drainage pipelines like PCCP pipes, steel pipes, FRP pipes are connected by socket welding and sealed with rubber washers which results in serious leakage with an average leakage rate of 15~30%. Correspondingly, it increased energy consumption and maintenance cost. UHMWPE pipe with its extraordinary performance successfully solved this problem and is a great revolution for water supply and drainage projects.

Low Energy Consumption

Friction resistance coefficient of UHMWPE pipes is 0.009 while that of steel pipe is 0.013 and that of cement pipe is 0.15. With the same diameter, UHMWPE pipe can deliver more water than PCCP pipe and others. With the same flow rate, UHMWPE pipes can save 25% energy than other pipes.

Maintenance Free

With characteristics of corrosion resistance, low temperature resistance, non-scaling, no leakage, etc, UHMWPE pipe can work without extra anticorrosive coating, cleaning and maintenance which save more than 95% energy.

Corrosion Resistance

With high chemical stability, UHMWPE can resist corrosion of corrosive media like acid，alkali and salt and organic solvent. It can be applied in water supply at seabed and transmission of salt water and acid or alkali fluid.

Low Temperature Resistance

At the temperature of -70 ℃，UHMWPE pipe can work with normal mechanical performance. It is suitable for water supply and drainage in cold area.

Non-scaling

With smooth inner wall and roughness of 0.00022, UHMWPE pipe can work for a long time without scaling and breeding bacteria , while roughness of PCCP and steel pipe is 0.01-0.09 which is easy scaling and growing moss therefore influencing the water quality and doing harm to human health.

Environment Friendly

UHMWPE is authorized by the nation as material being environment friendly, non-toxic, harmless to human health. UHMWPE pipe is the best alternative for water supply pipe.

High Pressure Resistance

The compressive strength of UHMWPE pipe is 2 times to that of PE100 pipe and 2.5 times to that of PE80. UHMWPE pipes can withstand wide fluctuate of water pressure in the pipeline. Its ring stiffness is more than 8 KN/㎡ which can withstand high load for the pipeline underground.

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.

Impact Resistance

UHMWPE pipe has good impact resistance and can withstand impact of water hammer. There is no need to build anchor block at the turning site.

Advantage of UHMWPE pipe in non-excavation water supply&drainage projects in urban areas

When placing traditional pipelines of PCCP, steel, FRP, we have to damage roads, plants and buildings while there is no need to excavate for installation of UHMWPE pipelines but for small tunneling machine to pull and place it. The length of pipeline placed at one time can reach 1000m.

Advantage of UHMWPE pipes in water projects in narrow area

UHMWPE pipe is light in weight and flexible. It can pass by the obstacles within the range of its bend radius. There is lower area compensation, and smaller excavation area, no need of large scale lifting machine, base and sand filling when placing the UHMWPE pipeline, only to push the connected pipeline into the pipe ditch, fill the earth in and compact it.

Advantage of UHMWPE pipes when pipeline crossing rivers

For PCCP, steel, FRP pipes, it is in need of reclamationdam, cement base when the pipeline is crossing rivers. Meanwhile, for UHMWPE pipes, it can be installed with non-excavation techniques or excavating pipe ditch to install without cement base. UHMWPE pipe has unique advantage than others.

Advantage of UHMWPE pipe in wetland projects

With characteristics of non-base, easy installation, low cost, fast and safe operation when the UHMWPE pipe are placed in wetland, it solves problems of PCCP, steel, FRP pipe like being necessary for large cement base, difficult to installation, dangerous operation, and difficult to maintain.

Advantage of UHMWPE pipes in seabed pipeline projects

Compared with PCCP, steel, FRP pipes being placed at seabed, UHMWPE pipel is no need of construction of base, maintenance free, and great energy saving.
