Is the steel mesh skeleton plastic composite pipe a rigid pipe or a flexible pipe

Steel mesh skeleton polyethylene composite pipe is a new type of pipe that is tightly connected with the inner and outer layers of high-density polyethylene with high-density polyethylene (HDPE) as the matrix and high-performance HDPE modified adhesive resin.

The steel wire mesh skeleton plastic composite pipe is a new type of steel skeleton plastic composite pipe that improves the car zhao. This type of pipe is also known as SRTP pipe.

This new type of pipeline is made of high-strength super-plastic steel wire mesh skeleton and thermoplastic polyethylene as raw materials, steel wire sail winding mesh as the skeleton reinforcement of polyethylene plastic pipe, with high-density polycracked ethylene (HDPE) as the matrix, and high-performance HDPE modified adhesive resin is used to closely connect the steel wire skeleton with the inner and outer layers of high-density polyethylene, so that it has excellent composite effect.

Because the high-strength steel wire reinforcement is encapsulated in a continuous thermoplastic, this composite tube overcomes the disadvantages of both steel and plastic pipes, while maintaining the advantages of both steel and plastic pipes.

Introduction of steel wire mesh skeleton plastic composite pipe

The steel mesh skeleton plastic composite pipe adopts high-quality materials and advanced production technology, which makes it have higher pressure resistance. At the same time, the composite pipe has excellent flexibility and is suitable for long-distance buried water supply and gas pipeline systems. The pipe fittings used in the steel wire mesh skeleton polyethylene composite pipe are polyethylene electrofusion pipe fittings.

When connecting, the heating element inside the pipe fitting is used to melt the outer plastic of the pipe and the inner plastic of the pipe fitting, and the pipe and the pipe fitting are reliably connected together. Light weight, easy to install, the pipe connection adopts electric hot melt joint, strong anti-axial tensile ability, mature and reliable connection technology, and pipe fittings are of variety and specification.

First, the pipe structure is different.

1. Steel wire mesh skeleton plastic with digging composite pipe.

Winding formed steel wire mesh in hot melt adhesive.

Under the effect of bonding with the inner and outer layers of plastic, due to the characteristics of the polyethylene material that the bridge body is difficult to stick, the bonding effect is general, and the quality uniformity of the pipe is poor because it is molded multiple times. Because the steel wires are only wound together and not welded, the grid spacing of the steel wire mesh is unevenly distributed, the structure is unstable, and the local strength of the pipe is very low where the steel wire spacing is large. Because the steel mesh does not support the plastic as well.

2. Steel skeleton plastic composite pipe: the inner and outer layers of the pipe wall are connected as a whole through the metal mesh in the middle of the pipe wall (like reinforced concrete.

The two materials are completely compounded into one, because the surface of the steel wire is very smooth and angular, and the flow resistance of the plastic is small and the extrusion is uniform during the molding process, so the quality of all parts of the pipe is uniform.

1. Stability. Because it is welded into a mesh, the grid spacing of the skeleton is consistent, the structure is stable, and the supporting effect on the plastic is strong.

Second, the size standards are different.

1. Steel mesh skeleton plastic composite pipe: the outer diameter is nominal. When connected with pumps, valves, etc., the inner diameter difference is large, and more reducer fittings are required, which increases the connection parts and leakage hazards.

2. Steel skeleton plastic composite pipe: the inner diameter is nominal, and the flow rate is scientific and reasonable. When connected with pumps, valves, etc., the inner diameter is consistent. The difference between the inner diameter of the pipe and the fitting is very small, and the flow resistance is small.

Third, the characteristics of the pipe are different.

1. Steel wire mesh skeleton plastic composite pipe: even if there is no corrosion problem, because the steel wire at the end of the pipe is not fixed (the bonding effect is not good), the steel wire will slide between the plastic layers under the action of pressure, resulting in the end part of the pipe no longer scattered and reinforced with steel wire, becoming a pure plastic pipe with a thin local wall thickness.

2. Steel skeleton plastic composite pipe: steel mesh welding and plastic extrusion are carried out simultaneously, the inner and outer plastic layers of the pipe wall are connected as a whole through the metal mesh in the middle of the pipe wall, there is no obvious interface between the steel wire and the plastic, the overall structure is similar to reinforced concrete, the two materials are completely composite into one, and the quality of all parts of the pipe is uniform.

First, the subject is different.

1. Steel wire mesh skeleton.

Composite pipe: It is made of high-strength superplastic steel wire mesh skeleton and thermoplastic.

Polyethylene is the composite pipe with polyethylene as the raw material and steel wire winding mesh as the skeleton reinforcement of the polyethylene plastic pipe.

2. PE pipe.

It is made by polymerization of monomer ethylene, due to the polymerization reaction due to pressure, temperature, etc. during polymerization.

Depending on the conditions, composite pipes with different densities of resin can be obtained.

Second, the characteristics are different.

1. Steel wire mesh skeleton composite pipe: It overcomes the rapid stress cracking phenomenon of plastic pipes, and because the structure of steel and plastic is composite, the rapid stress that is difficult to overcome will not occur because the structure of steel and plastic materials is composite.

2. PE pipe: PE pipe does not add heavy metal salt stabilizer during processing, the material is non-toxic, no scaling layer, and does not breed bacteria, which well solves the secondary pollution of urban drinking water.

Third, the application is different.

1. Steel wire mesh skeleton composite pipe: It is a new type of pipeline with excellent performance, which is widely used in oil fields, power plants, chemical and petrochemical enterprises, water supply companies, municipal gas, seawater utilization pipelines and other fields.

2. PE pipe: PE pipe is widely used. Among them, water supply pipes and gas pipes are its two largest application markets.
