Steel Wire Mesh Skeleton Reinforced HDPE Composite Pipe

The HDPE steel mesh skeleton plastic composite pipe represents an innovative type of structural wall pipe. It is constructed using high-strength steel wire and polyethylene plastic. The steel wire, serving as the core layer, is encased by high-density polyethylene plastic, which forms both the inner and outer layers, creating a unified pipe wall.

Description of Steel Wire Mesh Skeleton Reinforced HDPE Composite Pipe

The Steel Wire Mesh Skeleton Reinforced HDPE Composite Pipe is manufactured using premium materials and state-of-the-art production techniques, resulting in enhanced pressure resistance. Additionally, this composite pipe boasts exceptional flexibility, making it ideal for long-distance buried water supply and gas transmission systems. The fittings used with these pipes are polyethylene electrofusion fittings. During the connection process, the internal heating element of the fitting melts the outer plastic of the pipe and the inner plastic of the fitting, ensuring a secure and reliable joint
The Steel Wire Mesh Skeleton Reinforced HDPE Composite Pipe shares common features with other plastic pipes, such as corrosion resistance, non-scaling, smooth low resistance, thermal insulation without wax formation, wear resistance, and lightweight properties.

Additionally, its unique structure imparts the following distinctive characteristics

(1) Superior Creep Resistance and High Mechanical Strength
Plastic materials tend to deteriorate under normal temperatures and stress, leading to brittle fractures under prolonged high stress. Consequently, the allowable stress and load-bearing capacity of pure plastic pipes are relatively low, typically within 1.0 MPa. In contrast, steel possesses mechanical strength approximately ten times greater than thermoplastics and remains stable without creeping within the temperature range of plastics. When combined with plastic, the mesh steel skeleton effectively restricts the plastic’s creep, significantly enhancing its durable strength. As a result, the allowable stress of the wire mesh skeleton polyethylene composite pipe is double that of a pure plastic pipe.

(2) Excellent Temperature Resistance
The strength of plastic pipes generally diminishes as the temperature increases within their operational range, with a reduction of over 10% for every 10°C rise. However, since approximately two-thirds of the strength of the wire mesh skeleton polyethylene composite pipe is supported by the steel mesh skeleton, its strength decreases less with rising temperatures compared to any pure plastic pipe. Experimental data indicates that the strength of the steel wire mesh skeleton polyethylene composite pipe decreases by less than 5% for every 10°C increase.

(3) Rigidity, Impact Resistance, Dimensional Stability, and Moderate Flexibility
Steel’s elastic modulus is typically about 200 times that of high-density polyethylene. The rigidity, impact resistance, and dimensional stability of the polyethylene composite pipe with a steel mesh skeleton surpass those of any pure plastic pipe due to the reinforcing effect of the steel mesh skeleton. Additionally, the mesh steel skeleton’s inherent flexibility imparts some axial flexibility to the composite pipe. Consequently, the pipe exhibits a combination of rigidity and flexibility, offering excellent performance in loading, unloading, transportation, installation adaptability, and operational reliability. Ground installations can reduce the number of supports and lower costs, while underground installations can effectively withstand sudden impact loads from settlement, slippage, or vehicles. Small diameter pipes can be appropriately bent to follow terrain contours or arranged in a serpentine pattern, reducing the need for fittings.

(4) The thermal expansion coefficient is small
Due to the plastic pipe wire expansion coefficient of 10.6 ~ 12.2×10-6 (1/℃), pure plastic pipe wire expansion coefficient of 170×10-6 (1/℃), steel wire mesh skeleton polyethylene composite pipe under the constraint of mesh steel skeleton, the thermal expansion of composite pipe is greatly improved, lower than any kind of commonly used plastic pipe, through the test, The expansion coefficient of wire mesh skeleton polyethylene composite pipe is 35.4 ~ 35.9×10-6 (1/ C), which is only 3 ~ 3.4 times that of ordinary carbon steel pipe. The experimental results show that the heat compensation device can be used in buried installation, and the pipe can be absorbed (or released) by meandering laying, thus reducing the installation cost.

(5) Rapid cracking will not occur
Pure plastic pipe, especially large diameter pure plastic pipe, under the action of persistent circumferential stress at low temperature, easy to produce rapid cracking caused by local defects and stress concentration (momentary hundreds of meters to more than kilometers), so the current international requirements for the rapid cracking resistance of pipe plastic are very high, and low carbon steel does not exist brittle fracture problems. The existence of steel mesh makes the deformation and stress of the plastic not reach the critical point that causes it to crack quickly. Therefore, theoretically speaking, there is no rapid cracking of the wire mesh skeleton polyethylene composite pipe.

(6) The composite of steel and plastic materials is uniform and reliable
At present, the steel-plastic composite pipe on the market because the composite surface between steel and plastic is a continuous regular interface, long-term use under the action of alternating stress is easy to delamination, resulting in leakage at the connection, internal bottleneck contraction, blockage and failure. Compared with the wire mesh skeleton polyethylene composite pipe is a mesh structure through a special hot melt adhesive (modified HDPE) to make the plastic and wire mesh closely combined and integrated. The binding force between the two materials is large and uniform, and the stress concentration is small.

(7) Double anti-corrosion
The steel mesh skeleton is composite in the plastic through the special hot melt adhesive layer, the inner and outer surfaces of the pipe have the same anti-corrosion performance, wear resistance, the inner wall is smooth, the transportation resistance is small, no scale, no wax, the energy saving effect is obvious, and it is more economical and convenient for buried transportation and corrosive environmental conditions.

(8) Easily tracked
Due to the existence of the wire mesh skeleton, the buried wire mesh skeleton polyethylene composite pipe can be located by the usual magnetic detection method to avoid the damage caused by other excavation projects. This damage is pure plastic pipes and other non-metallic pipes produce the most damage.

(9) Product structure performance adjustment is convenient and flexible
The structure and performance of the product can be adjusted by changing the diameter of the wire, the spacing of the mesh, the thickness of the plastic layer, the plastic and the type to meet the different requirements of pressure, temperature and corrosion resistance.

(10) Special electric fusion joint, variety, installation is very fast and reliable
The connection of wire mesh skeleton polyethylene composite pipe adopts two ways: electrothermic connection and flange connection. The electrothermic connection is to insert the composite pipe into the electrothermic pipe fitting and electrify the electric heating wire embedded in the inner surface of the pipe fitting to heat it up. First, the inner surface of the pipe fittings is melted to produce melt, the melt expands and fills the gap of the pipe fittings, until the outer surface of the pipe also produces melt, the two melts melt together, and after cooling and forming, the pipe and the pipe fittings are closely connected as one.
