Product Description:


The Steel Reinforced PE Pipe is a new kind of high density polyethylene pipe which is reinforced by a steel wire skeleton. Crossing steel wire are spots welded as a net-cylinder structure during the manufacturing process. HDPE , the stuffing material of the structure ,is continuously extruded on producing line. The structure is similar to reinforced concrete structure.

This combination makes the pipe far stronger than standard HDPE pipe and more flexible and corrosion-resistant than steel pipe. Many of its inherent characteristics are far superior to those of HDPE or steel pipe.


The stuffing material of the steel mesh reinforced HDPE pipe and fittings is PE 80 (piping class), and the high quality low-carbon steel wire is used as the reinforced part of the pipes and Q235 steel sheet is used for the fittings.

a. Excellent corrosion resistance

Generally acknowledged as the anti-corrosion material, PE has an excellent property that can resist nearly 275 kinds of corrosive medium, such as non-oxidizing acid, alkali and saline solutions.

b.Super hydraulic performance

The absolute roughness of the steel mesh reinforced PE pipe is 0.01mm only while that of the steel pipe is 0.2mm. So the flow resistance is smaller and the conveying capacity is obviously higher than the normal steel pipe under the same condition.

c.Good flexibility and anti-seismic property

The steel mesh reinforced PE pipe has moderate elastic modulus. So it has excellent adaptability to the nonuniform settlement foundation and ground displacement. The good anti-seismic performance will reduce the cost of losses maximally when earthquake occurs.

d.Lighter weight and easier installation

The density of steel mesh reinforced PE pipe is only 40% of that of steel pipe, we don't need the lifting equipment on site when  installing pipes of small caliber. Using this kind of pipe can also save bend fittings benefit from the pipe laying according to the topography to the general undulating land. And the requirement of trench digging is less than steel pipe.

e.Super abrasion resistance

Generally, the abrasion property of polyethylene is superior to normal metal material .lt dedicates the abrasion resistance feature of steel framed reinforced PE composite pipe is exactly better than that of the normal steel pipes.

f.Excellent heat preservation property

The basic stuffing material of steel mesh reinforced PE pipe is polyethylene. The Thermal conductivity coefficient of PE is 0.43W/m℃,and that of the steel pipe is 2.5 W/m. So the heat preservation property is very good. Also we don't need any heat-insulation treatment even installing overhead.

g.Outstanding hygienic character

PE material is nontoxic and is widely used in food industry . The steel mesh reinforced PE pipe use PE as basic stuff ,and it has passed each test of the National Preventive Medical Association and gotten the Healthy Permit for portable water conveying. So our pipe can meet the requirements of Food Hygiene Law and Healthy Evaluation. At the same time, the inner surface of our pipe is bacteria free ,electrochemistry corrosion free and won’t introduce secondary pollution.

h.Working lifetime is longer and comprehensive cost is lower

The features of PE material ensure the working lifeof steel mesh reinforced PE pipe is much longer and comprehensive cost much lower than those of the normal steel pipe in the fields of conveying corrosive medium.

Benefit from the property of anti-corrosion, flexibility and heat preservation, etc., this pipe can be used on the industry of Mining, Oil, Gas, Chemical, the transportation of Ore Pulp and Tailings.

Q:Is the plastic lined steel pipe the same as the PSP composite pipe?
Now many places are using PSP steel composite pipe, pressure bearing ability, recommend you a family.
Q:What does "plastic steel composite pipe" mean?
Plastic steel composite pipe, the product of seamless steel pipe, welded steel pipe as the base pipe, painted on the interior of high adhesion, anti-corrosion, food grade hygiene polyethylene powder coating or epoxy resin coating.
Q:What is the difference between high-density PVC double wall corrugated pipe and steel skeleton PE composite pipe?
HDPE double wall corrugated pipe has excellent chemical stability, aging resistance and environmental stress cracking performance. The HDPE double wall corrugated pipe produced by the raw material belongs to the flexible pipe. Its performance is as follows:Strong resistance to external pressureThe outer wall of an annular corrugated structure, greatly enhance the ring stiffness of the pipe, so as to enhance the pipeline load on soil resistance, in this performance, HDPE double wall corrugated pipe compared with other pipe has obvious advantages.Low construction costUnder the condition of equal load, the HDPE double wall corrugated tube needs only thinner tube wall to meet the requirement. Therefore, compared with the solid wall pipe with the same material specification, the material of the utility model can save about half of the raw material, so the cost of the HDPE double wall corrugated pipe is also low. This is another outstanding feature of this pipe.
Q:What's the difference between aluminum alloy lined pipe and aluminium plastic composite pipe?
Lining plastic pipe is an ordinary carbon steel as base, lined with excellent chemical thermoplastic composite by cold or rotational molding, its mechanical properties both steel pipe and plastic pipe, corrosion resistance, corrosion and fouling characteristics, no growth of microorganisms, transport of acid and alkali, salt, there is an ideal pipeline corrosive gas medium.
Q:Plastic steel composite pipe what are the disadvantages?
Retains the traditional metal pipe steel and strength, far better than plastic pipes, aluminum pipe;The fire inside and outside the plastic pipe plastic composite pipe
Q:What are the connecting modes of steel wire mesh and plastic composite pipe?
Characteristics of electric fusion welding:Electric heating welding technology is convenient for construction. Prompt. The connection installation group can be implemented, and the uniform welding can be carried out.The welding reliability is good and the strength and density are better than those of other connections.Keep the inner wall smooth, without affecting the flow area.
Q:Is there any difference between steel wire mesh and polyethylene composite pipe for water supply and fire protection?
The winding wire mesh as the skeleton of polyethylene plastic pipe reinforced by high density polyethylene (HDPE) matrix, using high performance HDPE modified resin bonded steel skeleton and the inner and outer layer of high density polyethylene closely connected together, so that it has excellent composite effect.
Q:What is the structure and principle of the sample tube with heat sampling?
Automatic temperature limiting function with tropical temperature limit, can guarantee the sampling tube to maintain a certain temperature, so as to ensure as far as possible to collect samples consistent with the initial value, and ultimately ensure that environmental monitoring system continuously and correctly collect sample gas.
Q:Can steel wire mesh composite pipe sleeve HDPE Double wall corrugated pipe be fixed?
The Design Institute of rain water pipe connected with PE pipe. Apply the rainwater pipe fixed, the main sections into pe. Because the main difference in the material of pipeline installation.
Q:What is the difference between the PPR aluminium plastic composite pipe and the steady pipe?,
papAluminum plastic composite pipe is the earliest water supply pipe replacing cast iron pipe, and its basic composition should be five layers, namely, inside and outside are plastic, hot melt adhesive, aluminum alloy, hot melt adhesive and plasticPPR plastic composite pipe is composed of five layers, the middle layer of thin aluminum layer, the outer layer is PP-R, the inner layer is PE-RT, between the layers of imported hot melt, extruded under high pressure and high temperature, five layers of organic compound, corrosion resistance, light weight, high mechanical strength, good heat resistance, no fouling and long service life long and other excellent characteristics.
