UHMWPE complex pipe is made of UHMWPE pipe and carbon steel
pipe according to the scientific process. Its outer layer is the
steel pipe with flange as the enhanced protective layer, and its
inner layer is UHMWPE pipe as the matrix pipe. The inner UHMWPE
pipe is extended out of the outer layer of the matrix nozzle and
cover the flange face into a whole structure, so we can combine
UHMWPE pipe and carbon steel pipe to form the pipeline equipments
with the features of wear resistance, impact resistance,
anti-corrosion, resistance to high pressure, self-lubrication,
impact performance absorbing, anti-bonding. The pipeline
equipments are widely used in the transport of powder and coal
ash in thermal power system, backwater pipelines, the transport
of mine tailings and slurry in the mining industry, the
high-pressure transport of pulverized coal and coal-water slurry
of coal preparation plant in the coal industry, as well as the
transport of mud and corrosive media with slag in other
industries.
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 cant 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 cant 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 cant absorb water, and its specific weight is small. It is
easy to do mechanical working, and can be colored.
