Familiarity with polyethylene pipes
Polyethylene is obtained from the chemical synthesis of ethylene, which is obtained from compounds of crude oil and natural gases. Abbreviated as PE. Pure polyethylene is less used and the most common use of polyethylene is in plastic compounds and polyethylene pipes, which are used for water transmission system, municipal sewage, gas transmission pipe, fire pipes, oil product transmission lines, lines Industrial wastewater, air conditioning lines, mentioned in agriculture and dredging.
Origin of polyethylene pipe
It was first invented by a German scientist who, by heating a chemical, randomly produced a white substance that later became known as polyethylene. In fact, the German scientist was not familiar with the name or even the synthesis of this material, and the polyethylene pipe was discovered for the first time quite by accident.
Later, scientists made many efforts and developed a method of synthesizing this material, and each of these scientists completed the production cycle of polyethylene one after another. But the best method was discovered by a scientist named Michael Perrin, which is the usual method today (polymerization) that is done by catalyst devices. The history of using polyethylene pipes for gas transmission dates back to 50 years ago. In the beginning, black pipes were used and later, with more advanced than yellow striped pipes, it was used to transfer gas.
Where are the applications of polyethylene pipe?
Polyethylene pipes are one of the most widely used pipes in the agricultural, water, sewage and gas industries, fire pipes, oil transmission lines, industrial sewage lines, air conditioning and dredging lines. These pipes have been widely used in the country’s petrochemicals and are produced with high quality and competitive with foreign samples and even better than them in different sizes. Due to the advantages of polyethylene materials, its pipes are used from large factories to residential houses.
The advantages of this tube
The reason for choosing polyethylenes in the industry is easy formability, reasonable price, impact and sunlight resistance and their most important advantages are corrosion resistance, chemical resistance, light weight, ease of piping, transportation and installation. It’s easy. Polyethylene is produced in various petrochemicals across the country and is easy to access, so its price is affordable for consumers.
The long life of this pipe leaves natural resources untouched. Also, this product has an effective role in reducing greenhouse gas emissions. On the other hand, recycling of this product is easy and can be recycled to the last particle. So that these recycled materials can be used to produce other products. This will prevent the environment from being harmed.
Types of consumer polyethylenes
There are many types of polyethylenes; Such as single-walled water supply and pressure irrigation pipes in the agricultural industry, gas supply pipes from 20 mm to 3000 mm in the petrochemical industry and for water transfer and drainage and indoor sewage system and drinking water consumption and…. They are used, the main use of which is 6 to 10 bar pressure pipes.
One of the best types of these pipes today can be called screw pipes, which can be used without the need for a welding machine and through the female, and the drill has 5 main parts (screw, split, bushing, o-ring), so even if the damage See that it can be replaced easily and in the shortest time.
Recognize the best type of polyethylene pipes and fittings
The general public believes that to determine the quality of the pipe, it should be placed under a car tire, and if the pipe is damaged, it means its low quality, but this method is very incorrect and obsolete.
To determine the quality of polyethylene pipes, it is important to pay attention to the appearance of the pipe, which should have a smooth and polished surface and not be dry and brittle. But this is not the best way, the best way is to weld the polyethylene joints correctly and its welding durability. There are manufacturers who produce thick pipes to increase quality, but it is not possible to say which weight table they follow; In fact, these pipes are second-class pipes and it is better to know that second-class pipes do not have a standard seal, but they have a valid 5-year welding warranty from the pipe manufacturer.
Polyethylene pipes due to the availability of raw materials and reasonable prices and ease of working with them and having a variety in size and model have been able to find a special place in all micro and macro industries and is one of the most important and most widely used pipes in The whole world. Eventually, the production of these pipes has made great progress in various industries and has gradually become a suitable alternative to pipes with old production methods.
