PE Drinking Water Pipe

PE drinking water pipe

PE drinking water pipe is a material made of polyethylene resin as the main raw material, and the extruded polyethylene pipe for water supply is referred to as PE water supply pipe.

The production equipment of PE drinking water pipe is the German Decomo production line. The equipment is manufactured with the world's most advanced technology, with advanced performance of high-speed extrusion molding, moderate melting, automatic fixed-length cutting, and PLC control of the entire production process.

Execution standard of PE drinking water pipe: National standard GB/T 13663-2000.

The surface color of PE drinking water pipes is mainly black, and a few require white. The surface of the black tube body has a striking blue stripe.

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.
