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 water pipe in the house made of PPR pipe or stainless steel pipe? What brand is better?
As far as I know, or PPR, stainless steel has been eliminated, and the stainless steel is easy to rust, like home of our own is Su You PPR
Q:Can steel wire frame polyethylene composite pipe work as fire hose?
Can, plastic steel mesh skeleton plastic composite pipe for underground pipeline fire has been used in many engineering projects, steel wire reinforced composite pipe has the advantages of convenient installation, no corrosion, stable performance, excellent performance, construction speed has great advantages than traditional pipe, steel mesh skeleton composite pipe in the earthquake in Wenchuan is superior to the performance of its products to be fully affirmed. If there are more pipe problems, you can add.
Q:How welded wire skeleton plastic polyethylene composite pipe?
Steel skeleton plastic composite pipe laying and steel pipe, and pipe connection generally adopts electric melting connection and sleeve flange connection in two ways, and the connection between the pipe between the welding connection, pipes and pipe fittings fused the control points of construction. The important temperature parameters of polyethylene thermoplastic are glass temperature, viscous flow temperature, crystal melting temperature and pyrolysis temperature. When the plastic is above the viscous flow temperature or the crystal melting temperature, the plastic is melted into a viscous fluid by the solid state, and the welding is carried out in this temperature range. Hot melt welding principle established in semi crystalline thermoplastic polyethylene (HDPE crystallization degree is 85% ~ 95%) melting properties, melting process of polyethylene is basic ground connection interface by heating to melt state, contact theory according to the viscosity, by controlling the temperature and time are connected into a bond in under the action of pressure, the fusion zone can reach the same intensity of pipe.
Q:Construction technology of PE steel plastic composite pipe
PE the water supply pipe is connected by hot melt welding and electrofusion welding. The hot melt connection is divided into hot melt socket connection and hot melt butt joint, and the electric melting connection is divided into an electric melting plug connection and an electric melting saddle type connection.
Q:PE pipe and plastic lined steel composite pipe like?
The pressure is consistent with the pipe pressure above the PE80 pipe but equal or lower than the PE100 pipe.
Q:PSP plastic steel pipe and lining plastic pipe difference
PSP is the abbreviation of steel plastic composite pressure pipe, P is PE or PPR, PERT and other materials should be the initial letter, S steel English letter referred to, as the name suggests PSP is sandwiched between two layers of plastic steel, with the aim of internal and external corrosion types, such products generally have high water to melt connection pipeline, inside and outside the plastic pipe with the use of fire, underground pipeline steel mesh skeleton.
Q:How long is a plastic steel composite pipe?
Look at the material you use steel: seamless welded pipe 5.13kg/ meters, straight welded pipe is light, because the wall thickness is simply that 5.17 meters per meter, kg plastic steel composite pipe type more, you mean steel skeleton
Q:What is the difference between aluminum plastic composite pipe and aluminum plastic PPR pipe?
Generally, there are dimension indexes, inner diameter, outer diameter and wall thickness.Strength index, pipe strength indicators have radial compressive strength, that is, ring stiffness, flexibility index, bending index, impact strength, etc.For drinking water pipes, there are technical aspects of health indicators, as well as water pressure indicators.For the communications industry, there are other technical requirements.
Q:Steel wire frame composite pipe hot melt connection should be set what quota ah?
If there is no quota included, then can apply different pipe construction quota, no single set of items, unless it is beyond the diameter of the pipe fixed, the related item you can borrow for industrial pipelines, explain inside that quota
Q:Plastic steel composite pipe buried pipe how to connect?
Plastic steel composite pipe connection method: thread connection, groove connection and flange welding, steel plastic composite pipe is generally threaded connection.
