Product Description

PE pipe fittings are widely used in various industries due to their stable chemical properties, and gradually replace water supply pipes such as steel pipes and cement pipes. One after another, more and more pe pipe fittings manufacturers came into being. Many customers do not know how to choose good quality pe water supply pipe manufacturers, looking forward to buying good quality and cheap pe pipes.

High-quality PE pipe manufacturers need to meet many conditions, the quality of the manufactured PE pipe needs to meet the standard requirements, and the requirements meet the following conditions:

1. Color: The color of ordinary drinking water pipes is blue or black. Black pipes should have co-extruded blue color bars, which are usually three color bars. Other aspects can be blue or black, but the pipes exposed to sunlight must be black.

2. length: ordinary PE pipe length is 6 meters, 9 meters, 12 meters, can be customized according to your needs, the length can be based on unilateral agreement. The length bias cannot exceed 0.4 percent of the length and cannot be shorter than 0.2 percent of the length. The diameter of the coil should not be less than 18 times the outer diameter of the pipe.

3. Appearance: The pipes consumed by high-quality pe pipe manufacturers have lubricated and clean inner surface, no bubbles, no clear scratches, dents, magazines and uneven colors. The pipe end cut is flat and perpendicular to the pipe axis.

4. Health function: PE pipe fittings for drinking water should conform to the relevant guidelines of the national fake standard GB/T 17219.

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 pipes (HDPE) with their corrosion resistance, smooth inner wall, good fluidity, no scaling, light weight and convenient 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.

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.
