PE drainage pipe science small common sense
China's plastic pipes are developing rapidly and their quality is constantly improving. Because of its unique advantages, pe drainage pipe is widely used in building water supply, building drainage, buried drainage pipe, building heating, gas pipeline, electrical and telecommunication protection casing, industrial pipeline, agricultural pipeline, etc., mainly used in urban water supply, urban gas supply and farmland irrigation. Polyethylene material is widely used in the field of water supply pipeline manufacturing because of its high strength, corrosion resistance and non-toxic. Because it will not rust, it is the ideal pipe to replace the ordinary iron water supply pipe.

What are the connection steps and characteristics of pe drainage pipe?
When connecting the PE drain pipe, it is necessary to go through the steps of material preparation, cutting, heating, welding and docking, and cooling. The main characteristics of the PE drain pipe are excellent physical properties, good corrosion resistance, good toughness and flexibility. The following details the connection steps and characteristics of pe drainage pipe.

How to store PE water supply pipes at the construction site?
PE pipe because of its good compression resistance and acid and alkali corrosion resistance, in many liquid transportation projects have a very wide range of applications. For the storage of PE pipes on the construction site, the construction unit shall first prepare a flat open space, requiring no sharp protrusions on the ground, such as stones, bricks, etc., and no water. Try to store PE water supply pipes in a place that is dark, shady, ventilated and high-lying. After the pipes are transported to the site, the workers handle them lightly and transport the pipes to the specially vacated space, according to

PE pipe installation construction scheme
Overview of 1. pipes PE water supply pipe as a new type of pipe, with corrosion resistance, non-toxic, smooth inner wall resistance, anti-aging long service life (50 years), light weight (density is only 1/8 of the steel pipe), installation labor intensity Low, low construction cost, strong seismic performance, good material flexibility and other characteristics. The mobilization and inspection of 2. materials In order to ensure the quality of the project, we shall fill in the mobilization declaration form before the materials enter the site and submit it to the supervisor for acceptance. The supervisor shall check and accept the varieties, specifications and appearance of the materials entering the site according to the specifications (GB50242--2002). The packaging shall be in good condition and the surface shall be free of scratches and external.

Precautions for construction and installation of PE water supply pipe
1. pipe groove excavation 1. The pipe groove excavation should be straight line, and the groove bottom excavation width is DN 0.30m. When the pipeline is connected underground, the width of the groove bottom at the interface shall be appropriately increased, and the width of the groove bottom of the pipeline shall not be less than DN 0.50m to facilitate the installation and docking. 2. When the pipeline is buried, the minimum pipe top covering depth shall meet the following requirements: ① When buried under the roadway, it shall not be less than 0.80m. When buried under the sidewalk, it should not be less than 0.60m. 3. When the design depth is not reached across the carriageway, steel casing shall be laid for protection. 4. When the pipe groove must be turned, the turning angle should not be used.

The action essentials of removing the support after the pe pipe hot melt
1. Before the formwork support is removed, the concrete strength must meet the design requirements and can only be carried out after being declared and approved. Demolition of the template is generally done with a long pry, and people are not allowed to stand on the template being dismantled. When dismantling the floor template, attention should be paid to the fall of the whole template, especially when the qualitative template is used as the platform template, more attention should be paid to prevent the template from suddenly falling and hurting people. 2. When removing the formwork, a warning area must be set up and someone must be assigned to monitor it. Formwork removal must be thoroughly removed, and no suspended formwork shall be retained. The removed formwork shall be cleaned in time and stacked neatly. The removed formwork and support shall be transported to the ground with vertical lifting equipment, and no littering shall be allowed.
What is the prospect of installing and using PE pipes
With the continuous development of society, high cost performance, high quality and low price PE pipe in our life is more and more widely used, because the price of PE pipe is not very high, so we often ignore the identification of PE pipe quality, leading us to buy back inferior PE pipe, so how to identify the quality of PE pipe is good or bad. First of all, after we get the PE pipe, we should first check the surface smoothness of the PE pipe to make the most preliminary identification. Then we should drop the sample to check whether the PE pipe is a high calcium product. The high calcium product is easy to break. However, if the price of the PE pipe is reasonable and meets our production needs, we should choose it.
