Product Description
Ultra-high molecular weight
polyethylene (UHMWPE) is a kind of engineering thermoplastics with
more than 2 million viscosity-average molecular weight, under the
polymerization of ethylene, butadiene monomer in the catalyst.
Ultra-high molecular weight polyethylene pipe has the superior
performance such as very high wear resistance, impact resistance,
excellent resistance to internal pressure strength, resistance to
environmental stress cracking, eminent self-lubricating,
anti-adhesion, the unique low temperature resistance, good chemical
stability and so on, and it is widely used in metallurgical mines,
electric power, petroleum, natural gas, textiles, paper making,
food, chemical industry, machinery, electrical and other
industries.
Ultra-high molecular weight
polyethylene (UHMWPE) pipe characteristics
1. Extremely high wear resistance
UHMWPE pipe has 2 million or more molecular
weight, the smallest wear index, which makes it have a very high
capacity of anti-sliding friction. Its wear resistance is 6.6 times
higher than normal alloy steel, *7.3 times that of stainless steel,
*7.9 times that of phenolic resin, 6 times that of nylon 6, 4 times
that of polyethylene, and it increases the life of the pipeline
substantially.
2. Very high impact resistance
Of the existing
engineering plastics, the value of the impact toughness of
ultra-high molecular weight polyethylene pipe is the highest, and
many materials will crack, break, split or surface stress fatigue
in the explosion of serious or repeated impact. Our products will
not damage by Cantilever beam impact test according to GB***3
standards, and can bear strong external impacts, internal overload
and pressure fluctuation.
3. Corrosion resistance
UHMWPE is a kind of
structure of saturated molecules, so its chemical stability is very
high. It can withstand the erosion of potent chemical substances,
and it is not subject to corrosion in other lye and acid except for
some mild acid at high temperature outside. UHMWPE can be used in
the concentrated hydrochloric acid with less than *0%
concentration, and its performance is quite stable in the sulfuric
acid with less than *5% concentration and in the nitric acid with
less than *0% concentration.
4. Good self-lubrication
UHMWPE pipe contain the waxy
substance itself, and its self-lubrication is very good. The
frictional coefficient (**6N, 2 hours) is only 0.**9MN/m (GB***0),
so its self-lubrication is better than steel or brass with oil
lubrication. Especially its dry lubrication can be fully displayed
in the poor environment and places of more dust and sand. It not
only can be used freely, and can protect the workpiece from wearing
or strain.
5. The unique resistance to low temperature
The
resistance to low temperature of UHMWPE pipe is excellent, and its
impact resistance and anti-abrasion can’t change basically at minus
**9 degrees Celsius. It is the only available engineering plastics
can work at temperatures close to absolute zero. Meanwhile, the
adaptable temperature range of UHMWPE pipe is large, and it can be
used within ***9 to *0 degrees Celsius.
6. Not easy to form dirt
UHMWPE pipe has excellent
surface non-adhesion and surface smoothness due to its small
friction coefficient and non-polarity. Existing materials form dirt
usually in the medium with PH value of 9 or above, but UHMWPE pipe
can’t form dirt. This characteristic has great significance to the
system of discharging powder and coal ash of power plant, and is
also well suited for the pipeline of crude oil, mud and so on.
7. Long life-span
The unsaturated genes of UHMWPE
molecular chain are less, and its fatigue resistance strength is
more than **0 thousand times, and its Environmental Stress Cracking
Resistance is more than ***0h, which is twice more than the PE. It
can still maintain more than *0% mechanical properties after it is
buried and used for *0 years.
8. Easy installation
The weight of unit length of UHMWPE
pipe is only one-eighth of the steel pipe, which makes loading and
unloading, transportation, installation be more convenient, and can
reduce workers’ labor intensity. Anti-aging properties of UHMWPE
pipe are very strong, and it is not easy to get aging within *0
years, regardless of setting up on the ground, or being covered
underground. It is possible whether it is welded or connected by
flange when install. Safety, reliability, swiftness, convenience,
no anti-corrosion and labor-saving effort all fully show the
superiority of "energy conservation, environmental protection,
economy, efficiency" of UHMWPE pipe.
9.non-toxic for
food
*0. Other characteristics
UHMWPE pipe can also absorb
energy, absorb noise and resist static electricity, and holds
shielding ability to the electron. It can’t absorb water, and its
specific weight is small. It is easy to do mechanical working, and
can be colored.
