Polyethylene pipes have been seen in various types since the launch of the production line. These pipes have received much attention due to their high performance and special features. The advantages of polyethylene pipes far outweigh their disadvantages, but this article has tried to address the advantages and disadvantages of polyethylene pipes simultaneously.<\/p>\n
Since the arrival of polyethylene pipes in industrial areas, this product has been considered due to its special properties and practicality. This section has tried to explain the most important advantages of polyethylene pipes:<\/p>\n
1- Earthquake resistant: Due to its strength against impact pressure and high tensile strength, polyethylene pipes are very resistant to earthquakes, drift and vibration.<\/p>\n
2- Flexibility: This feature makes it easy to install pipes and reduces the need to use fittings. The allowable bending radius of polyethylene pipes is on average 20 times its outer diameter.<\/p>\n
3- Light weight: Due to the low weight of this pipe compared to steel pipes, its transportation and loading will be much easier, resulting in reduced costs.<\/p>\n
4- Resistant to electrolytic corrosion: This property becomes more important when the pipe is located near seawater. The combination of air and seawater causes serious corrosion of metal pipes, and polyethylene pipes are resistant to this corrosion.<\/p>\n
5- Shrinkage: Properties due to weathering and expansion and contraction, polyethylene pipes have better shrinkage properties than other pipes.<\/p>\n
6- Resistant to ultraviolet rays of the sun: This product is one of the few polyethylene products that, by adding appropriate black materials and using modern production line equipment, has very good resistance to ultraviolet rays of the sun.<\/p>\n
7- Very good hydraulic properties: Due to the completely smooth and polished inner surface of the polyethylene pipe, its friction losses in long pipelines are lower than other pipes.<\/p>\n
8- Resistant to decay, wear and tear: The use of standard consumables to resist decay, wear, corrosion and abrasion increases the useful life of polyethylene pipes.<\/p>\n
9- Low maintenance cost: Due to the long life of these pipes, there is little need for repairs. Repairs can be done at a very low cost if necessary. Meanwhile, repairing steel pipes brings many problems and costs.<\/p>\n
10- Strong and leak-free connections and at the same time flexible: Due to the strong electrofusion or butt welding connections with welding or flange connections, these properties are formed, these connections can be connected to parts using screws or welding.

Compared to the advantages of buying polyethylene pipes, its disadvantages can be ignored. In fact, it can be called a weakness because there is a way to fix it. Now, in this section, we have only mentioned the weaknesses of polyethylene pipes to remove ambiguity and increase the reader’s awareness.<\/p>\n
1- Decrease in resistance over time and with increasing temperature: The lifespan of a polyethylene pipe is the relationship between internal pressure and fluid temperature. The lifespan of a polyethylene pipe is predicted and determined to be 100 years, assuming that the fluid temperature is 20 degrees Celsius and the ambient temperature has little effect, and the polyethylene pipe is resistant to very hot and very cold ambient temperatures. No problem comes to them<\/p>\n
2- The need to protect against the harmful effects of ultraviolet rays: This was a weakness in the early years of polyethylene pipe production, and today, its solution is to import black polyethylene materials. If the pipe is made of white and natural materials, they use a special masterbatch for the pipe that contains anti-ultraviolet radiation.<\/p>\n
3- Weakness against suction and vacuum created in the pipe: In the production of the inner layer of single-wall polyethylene pipe and double-wall corrugated pipe, polyethylene pipe finds its shape due to vacuum and suction. They are also more resistant to suction than the pressure they have to withstand. Because air is a fluid with variable pressure and polyethylene pipe will also be affected by this pressure.<\/p>\n
4- Deep scratches and cuts on the surface of the pipe during transportation or installation: One of the weaknesses of polyethylene pipes is when transportation is not carried out according to the instructions. The outer body of the pipe is deeply scratched. The pressure tolerance of single-wall polyethylene water supply pipe is based on the thickness of the pipe. If a scratch of a few millimeters is created, the pressure tolerance at that point will be less than the standard and defined value.<\/p>\n
5- Possibility of destructive effects of some petroleum and chemical substances: Polyethylene pipe is not resistant to some petroleum substances. It is not recommended for transporting gasoline, diesel and oil, and some chemicals such as alcohols, halogens and aromatics have a bad effect on the pipes.<\/p>\n
6- Failure to find the pipe in the trench with a metal detector<\/p>\n
7- Possibility of reducing the useful life of the pipes due to chlorinated water<\/p>\n","protected":false},"excerpt":{"rendered":"
