What is UHMWPE pipe?

What is UHMWPE pipe?

Material introduction: 
UHMWPE (Ultra High Molecular Weight Polyethylene) has extremely long chains, with molecular weight numbering in the millions (usually between 2 to 6 million, the pipeline  raw material we quoted you is 3.5million). In general, HDPE molecules have between 700 and 1,800 monomer units per molecule, whereas UHMWPE molecules tend to have 100,000 to 250,000 monomers each. The chains of UHMW align in the same direction. The bonds between the chains are not very strong however, because they are so long there are more bonds holding it together then polyethylene with shorter chains. These long chains give UHMW high tensile strength. The longer chains serve to transfer load more effectively to the polymer backbone by strengthening intermolecular interactions. This causes the material to be very tough and gives it the highest impact strength of the polyethylenes. It has a density of 0.928-0.941 g/cm3.

Collision Resistant UHMWPE Plastic Buoy

Collision Resistant UHMWPE Plastic Buoy 

UHMW-PE Navigation Buoy is kind of signal for vessel guiding, positioning, obstacles marking and warning marking. The buoy consists of light stand, floating body and tail pipe. The light stand is used for the signal light, which will provide light signal for vessels, the floating body will provide sufficient buoyancy for the buoy, and the tail pipe with ballast is to guarantee the stability of the buoy.

The raw material of the UHMWPE plastic buoy is Ultra High Molecular Weight Polyethylene, which is a polyethylene polymer with an average molecular weight greater than 1,500,000 .  This molecular weight is well above the molecular weight of most typical polymers which are between 1,000,000 and 400,000 thus earning the title Ultra-High Molecular Weight Polyethylene. Because of the ultra high molecular weight, the UHMWPE plastic buoys have the following advantages:

UHMWPE plastic buoy advantages:

a.Maintenance free:

The color of the floating body is material's color without painting(The color is moulded in, so the floating body needs no painting); the UHMWPE floating body and tail pipe is not easy to adhere to water growth, which minimize the costs for cleaning.

b. Collision Resistance:

The floating body with great resilience, stretch resistance, and inside with scientific physical structure, thus it could absorb the collision force, when it was impacted, it can rebound immediately without deformation.

c. Longer service life:

 The floating body and tail pipe material is UHMWPE and scientific formulations, with higher chemical stability and corrosive resistance, thus it could keep mechanical properties without aging for at least 20 years. Also it has passed the 200h Xenon lamp aging test without fading and aging.                                                                              
d. Environment Friendly:

The main material of UHMWPE buoy is UHMWPE, which is non-toxic and tasteless, has no pollution to the environment during the manufacturing process and operation process.

DN800mm UHMWPE pipe 

Advantage of UHMWPE escape pipe:
The escape tunnel has excellent comprehensive properties. There is no other enginnering

plastics comparable to UHMWPE's shock resistance, high pressure resistance, abrasion

resistance, aging resistance, light weight, and chemical corrosion resistance, non-toxic, 
no easy adhesion, in foreign countries known as "magical plastic". Therefore, it is widely

used in the fields of machinery, transportation, textile, paper making, mining, agriculture,

chemical industry and so on.

- light weight, which is about 1/8 of steel weight, convenient disassembly and

transportation.

-The pipeline of good toughness, high impact strength, the instantaneous deformation under

strong impact, absorbing impact energy, and then quickly restore to the original shape,

provides safe and reliable guarantee for the construction of highway tunnel emergency

escape.

-The UHMWPE pipe has high ring stiffness, good pressure resistance, not easy deformation, in

highway tunnel construction collapse, bearing capacity and anti environment damage ability

far more than the general pipeline.

From 2004 to 2007 according to the tunnel construction accident statistics, 39 occurred in

China (highway, railway tunnel construction accidents). Due to the diversity and complexity

of the geological conditions, the occurrence rate of the highway tunnel construction is

higher than that of other geotechnical engineering.

Therefore, the collapse of emergency rescue technology of highway tunnel construction will

be able to effectively reduce casualties and property losses of the construction of highway

tunnel collapse accident, which has important practical significance to improve the safety

of highway tunnel construction. However, the existing emergency rescue channel of current

road tunnel construction is  steel pipe,which is very heavy, more bulky, inconvenient

disassembly and transportation, low efficiency of use. At the same time, in the selection of

emergency rescue pipeline, the pipeline needs to have high impact resistance, high pressure

resistance, high wear resistance and other excellent properties.

The feasibility of using super high molecular weight polyethylene pipe to the emergency

rescue channel of highway tunnel was demonstrated by the impact test and pressure test.

Meantime, from the angle of human engineering, the structure size of the new type of

emergency rescue channel is optimized.

The hull of dredging floaters are made from PE material with good flexibility, and it is filled with high density polyurethane foam inside. With reasonable structure and good performances, the polyethylene dredging floaters are ideal to replace the steel pontoons for the floating discharging pipe.

1. Good flexibility and excellent impact resistance, particularly suitable for the installation in the sea;

2. Light weight, easy for installation and handling, with lower costs for transportation;

3. Corrosive Resistance with longer working life, it could work 3 times longer than steel pontoons.

4. The costs and performances are more economical than steel pontoons.

High wear resistance

The wear resistance ability of UHMWPE pipe is 4 to 7 times of Q235 steel pipe or PE100 pipe

Which means :

Longer Working life

Less Maintainence cost

Less downtime for  pipe replacement and rotation

Extremely Smooth

Surface roughness of UHMWPE pipe is 0.00022mm superior to PTFE (Teflon).

 UHMWPE has a friction coefficient of 0.05 compared to 0.28 for HDPE or 0.58 for steel (ISO 8295) 

For its Exrtemely smooth surface, UHMWPe pipe has far superior anti scaling property to any other pipelines on the market curretly

Which  means:

 less friction loss, less pressure loss and greatly reduced energy inputs to deliver the same result.

By our test, in the same working condition, UHMWPE pipe water head loss is 30% less than HDPE pipe and 50% less than steel pipe.

High impact strength, flexible and light

UHMWPE is 5 times of oridinary PE pipes, 4 times than HDPE, 2 times of polycarbonate pipe, and 10 times of PTFE pipe.

It means easy installation and less installation cost

High corrosion resistance

For its saturated molecular structure, it has high chemical stability, resistance to all kinds of corrosive medium (acid, alkali, salt) and organic solvent.

It will offer longer life than other pipelines in acid or corrosive applications.

UHMWPE pipe is widely applied for the sand/slurry dredging project, mine tailing discharging project.
