PE Power Conduit

Product Description

PE threading pipe is a high-tech product which is processed and formed by extrusion with high-quality high-density polyethylene resin as the main raw material, adding appropriate additives. The product has the characteristics of corrosion resistance, anti-aging, impact resistance, high mechanical strength, long service life and excellent electrical insulation performance.

Application field

Widely used in urban road construction, community development, garden landscape, enterprise construction and other places, as the cable threading sheath for electric power, street lamps, lawn lamps, garden lamps, residential intelligence, cable TV, communication, intelligent transportation, etc.

Product Specifications

Nominal outer diameter: dn16- 1800mm (can be customized)

Nominal pressure: 0.4mpa-1.6mpa (customizable)

Features

1. Excellent physical properties: It is produced with high-quality polyethylene raw materials. It has good rigidity, strength and flexibility. Facilitates the installation of pipes.

2. Corrosion resistance and long service life. In coastal areas, the groundwater table is high and the land humidity is high. The use of metal or other pipes must be anti-corrosion, and the service life is generally only 30 years. The PE pipe can withstand a variety of chemical media and is not affected by soil corrosion.

3. Good toughness and deflection: PE pipe is a kind of high toughness pipe, and its elongation at break exceeds 500%. The ability to adapt to uneven ground subsidence and dislocation of the foundation is very strong. Good shock resistance. Small diameter pipes can be bent arbitrarily.

4. The pipe wall is smooth, the friction coefficient is small, the cable threading is easy, and the construction period efficiency is high.

5. Good electrical insulation performance, long service life (over 50 years for buried pipes), durable, safe and reliable line operation.

6. Light weight, easy maintenance, installation and construction, easy maintenance, easy transportation and operation.

7. Small-diameter pipes can be in the form of coiled pipes, with long pipe sections, few joints, and easy installation.

8. The pipes can be made into a variety of colors to show distinction.

9. Excellent low temperature impact resistance: PE has a very low low temperature embrittlement temperature and can be used safely within the temperature range of -20-40. During construction in winter, due to the good impact of the material, the pipe will not be brittle.

10. Good wear resistance: Compared with other metal pipes, PE pipes. Wear resistance is 4 times that of metal pipes.

11. A variety of new construction methods. In addition to the traditional excavation method for construction, PE pipes can also be constructed by a variety of new non-excavation techniques, such as pipe jacking, lining pipe, cracking pipe, etc. the right choice.

Product Description:

1. The product implementation standard is: CJ/T189-2007 "Steel mesh skeleton plastic (polyethylene) composite pipe and pipe fittings".

2. Composite pipes of the same specification and different pressure levels have different wire diameters and grid parameters.

3. The nominal pressure is the maximum working pressure of the pipe to transport the water medium at 20°C. If the medium temperature changes, it should be corrected according to the "nominal pressure correction coefficient value".

4. The color of the pipe is generally black, the gas pipe is black or blue, and the black pipe should have a blue color bar.

5. Pipe fixed length: 6m, 12m, can also be determined according to user requirements and transportation conditions

Performance comparison of steel mesh skeleton plastic composite pipe and welded steel skeleton plastic composite pipe:

First: the production process of steel mesh skeleton plastic composite pipe and welded steel skeleton plastic composite pipe is different

1. Composite structure. The welded steel skeleton plastic composite pipe is based on ordinary carbon steel wire. Although the steel wire is relatively thick, the tensile strength is only 400Mpa, the process is complicated, and the product quality fluctuates greatly. Steel mesh skeleton plastic (composite pipe, high-strength steel wire (above 1950Mpa) is used as the base material, and the steel wire is wound on the pipe in a 54.7-degree oblique direction, so that the pipe can be axially and The force is uniformly distributed in the circumferential direction, and a high safety factor is adopted when determining the diameter and density of the steel wire.

2. Water channeling on the end face. Welded steel skeleton plastic composite pipe, due to the inevitable gap between the PE material pipe and the steel plate, when the pipe is cut, the end face is sealed, but the seal is easy to fall off when heated with electrofusion pipe fittings. After installation, the medium will enter the gap between the steel plate and the plastic, resulting in a decrease in the pressure bearing capacity of the entire pipeline system. As a result, the pipe will be damaged at low pressure, resulting in the failure of the pipe.

Second: the product standards of steel mesh skeleton plastic composite pipe and welded steel skeleton plastic composite pipe are different. The steel mesh skeleton plastic composite pipe implements CJ/T189-2007, and the steel skeleton composite pipe implements the CJ/T123-2004 standard;

Third: The steel skeleton composite pipe can be overhead, but the steel mesh composite pipe cannot be overhead.
