PE water supply pipe-PE pipe production

During the installation of pe pipe, the construction log must be filled in carefully every day. The contents include the temperature of the day and whether there is wind, etc. The wall thickness and pressure of the welded pipe, the model and specification of the welding machine, the temperature and voltage of the heating plate, the length of the welded pipe on the same day, several welding joints, several pipe fittings and positions, the name of the installer, etc.; In order to verify in the future.

Product Description

In recent years, with the needs of China's development to an energy-saving society, as well as the continuous improvement of people's quality of life and the enhancement of health awareness, the requirements for the quality of drinking water for domestic use are also increasing day by day. New plastic pipes have been widely used in urban water supply with their superior performance, especially high density polyethylene pipe (HDPE)pe pipe with its corrosion resistance, smooth inner wall, good fluidity, no scaling and light weight, easy installation, long service life, environmental health, low leakage advantages, get rapid development. In the course of its use, the quality of the pipe joint welding is related to the length of the service life of the pipe and whether the pipe is leaking. However, the recent news found in some places in the construction, because the construction is not in accordance with the standard operation, do not pay attention to the construction quality, there have been some water leakage accidents, resulting in some adverse effects. To this end, the installation of polyethylene (PE) pipe is summarized.

1. attach importance to the training of pe pipe installation technicians

1. Installation technicians must be formally trained before taking up their posts.

2. Training content: basic understanding of plastic pipes, correct use of different types of installation machines, maintenance of installation machines, safe and civilized construction on site, basic procedures and precautions for welding pipes, etc.

3. The construction unit is required to have fixed trained and qualified plastic pipe welding technicians.

2. requirements during the installation of pe pipe, every day must carefully fill in the construction log. The contents include the temperature of the day and whether there is wind, etc. The wall thickness and pressure of the welded pipe, the model and specification of the welding machine, the temperature and voltage of the heating plate, the length of the welded pipe on the same day, several welding joints, several pipe fittings and positions, the name of the installer, etc.; In order to verify in the future.

3. safety construction is mainly the safety of electricity. To regularly check and maintain the installation of the machine, check whether the wire joints are wrapped in good condition; try not to construct in rainy days, so as not to cause leakage accidents due to moisture, and pay attention to prevent the installation of the machine from being damaged by rain and damp, resulting in accidents.

HDPE water supply pipe:
1. Reliable connection: PE pipe systems are connected by electric melting, and the strength of the joint is higher than that of the pipe body.
2, good low temperature impact resistance: PE pipe low temperature embrittlement temperature is very low, can be used safely in the low temperature range. During winter construction, the material will not crack due to its good impact resistance.
3. Good stress cracking resistance: PE pipe has low notch sensitivity, high shear strength and excellent scratch resistance, and its environmental stress cracking resistance is also very prominent.
4, good chemical corrosion resistance: PE pipe can resist the corrosion of a variety of chemical media, the chemical substances in the soil will not cause any degradation of the pipeline. Polyethylene is an electrical insulator, so it does not decay, rust or electrochemical corrosion; in addition, it does not promote algae, bacteria or fungi growth.
5. Aging resistance and long service life: polyethylene pipes containing 2-2.5% evenly distributed carbon black can be stored or used outdoors for 50 years without being damaged by ultraviolet radiation.
6, good wear resistance: PE pipe and steel pipe wear resistance comparison test shows that the wear resistance of PE pipe is 4 times that of steel pipe. In the field of mud transportation, compared with steel pipes, PE pipes have better wear resistance, which means that PE pipes have a longer service life and better economy.
7, good flexibility: the flexibility of PE pipe makes it easy to bend, engineering can bypass obstacles by changing the way of pipe direction, in many occasions, the flexibility of the pipe can reduce the amount of pipe fittings and reduce installation costs.
8. Low water flow resistance: PE pipe has a smooth inner surface, which has a higher conveying capacity than traditional pipe, and also reduces the pressure loss of the pipeline and the energy consumption of water delivery.
9, easy to handle PE pipe than concrete pipe, galvanized pipe and steel pipe lighter, it is easy to handle and install, lower manpower and equipment requirements, means that the installation cost of the project is greatly reduced.
