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.
