Description
Self-Lubricating UHMWPE Floating Pipe For Dredger 1.Brief
introduction of Floating Pipe For Dredger Ultra-high molecular
weight polyethylene (UHMWPE) Dredger Pipe 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, easy installation 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. 2.Raw
material of Floating Pipe For Dredger UHMWPE is a thermoplastic
engineering plastic with a viscosity-average molecular weigh
greater than 1.5×**6, and is made by polymerization of ethylene
under the action of a catalyst. Its molecular weight has reached
over 5 million, its five properties of abrasion, impact and
corrosion resistance, self-lubrication, and absorption of impact
energy are the best among the available plastics. It is called
globally “marvelous plastics” UHMWPE, a new star of materials, will
present a vigorous life and play an important part in many regions
of the national economy. 5.Characteristics of Floating Pipe For
Dredger 1).Extremely high wear resistance; 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).High impact resistance: It won’t
damage by Cantilever beam impact test according to GB***3 standards
3).High corrosion resistance: It can withstand hydrochloric acid
with less than *0% concentration 4).High-pressuer resistance: The
working pressure is between 0.2Mpa to 4.0Mpa 5).Good
self-lubrication: Its self-lubrication is better than steel or
brass with oil 6).The unique resistance to low temperature:It can
be used within ***9 to *0 degrees Celsius. 7).Not easy to form
dirt: It can’t form dirt in the medium with PH value of 9 or above
8).Long life-span:It can maintain more than *0% mechanical
properties after it is buried and used for *0 years. 9).Easy
installation:The weight of unit length of UHMWPE pipe is only
one-eighth of the steel pipe, it is possible whether it is welded
or connected by flange. 6.Applications of Floating Pipe For Dredger
1).transport powder and coal ash in thermal power plant.
2).transport mine tailings and slurry ,metallurgical mines,in the
mining industry. 3).transport pulverized coal and coal-water slurry
of coal preparation plant in the coal industry. 4).transport mud
and corrosive media with slag in the chemical industry.
5).transport crud oil,petroleum, food and natural gas.
