The role of pipes and fittings in the construction industry is very important today. Pipes are divided into several categories in terms of fittings, materials and applications. Polyethylene pipes are one of the types of plastic pipes that have become one of the most widely used pipes in the world today due to their widespread acceptance. These pipes are manufactured in different sizes and sizes depending on their user.
For example, a 63mm or 2 Inch Poly Pipe Fittings is considered to be the main pipe in various industries and projects, which is manufactured at different pressures from 5 to 32 times. It is also available to consumers with a 6-meter-long, 100-to-150-meter coil.
Which pipe is best? And why?
In fact, the best way to perform bridge plumbing in transmission projects cannot be a fixed one, because each project can be implemented in different ways depending on the purpose of the project and also the material designed and purchased.
As well as the quality of pipe and fittings in transmission projects, proper implementation and standardization of the project, according to the client and project supervisor, is also important. Therefore, choosing the right contractor and executor of plumbing projects is of the utmost importance. In contractor and welder selection, the contractor should have the capacity and ability to operate as well as the plumbing contractor’s equipment and supplies along with the correct and standard execution of the project as required. Provided enough attention. The project will also be carried out in accordance with the standard in the time provided by the employer.
One of the best and most popular pipes today is polyethylene pipes. Classification of polyethylenes is based on their density, which is related to the density value of the polymer chain size and the type and number of branches in the chain.
- HDPE (High-Density Polyethylene): This polyethylene has higher tensile strength than other PEs.
- LDPE (Low-Density Polyethylene): This polyethylene has low tensile strength. Other features of this polymer are flexibility and degradability by microorganisms.
- LLDPE (Low-Density Linear Polyethylene): This polyethylene is a linear polymer with a number of short branches and is usually formed by copolymerization of ethylene with long-chain alkenes.
- MDPE: Medium density polyethylene.
Types of polyethylene used in pipe industry :
In the manufacture of polyethylene pipes, two types of PE are commonly used, namely PE80 and PE 100. The characteristic number of the MRS material is said to be the minimum resistance required after 1 year of operation at a fluid temperature of 2 ° C. Increasing the number indicates further improvement in the quality of the products produced. Accordingly, in many countries there have been many efforts to replace PE100 with PE80.
Among the reasons polyethylene pipes are best described are their advantages. Here are some of the benefits :
- Easy connectivity
- High flexibility
- Easy installation and low cost
- Long service life, durability and cost savings
- Corrosion resistance and chemical effect
- Easy to use
- Low polyethylene friction coefficient and its constant during application
Compare with other types of materials :
Nowadays hdpe fusion fittings have found their place in high-pressure applications. This is especially evident when the diameter of the tube is less than 2 mm. Because employers and project consultants often come to the conclusion that the raw material costs and their desired properties of the pipe are high, polyethylene pipes are the best choice compared to other types of pipes.
Which pipes are better for water supply?
Today, HDPE (hard polyethylene) polyethylene pipes based on PE63, PE80, PE100 are used for conveying rural and urban water. Drinking water from smooth surfaces is not always smooth. Rather, there are many natural obstacles, such as mountains, valleys, and rocky surfaces. It is clear that the implementation of a development project should not harm nature. In addition to nature conservation, the cost and speed of implementation of water supply projects are of great importance.
The superior properties of polyethylene compared to other options such as metal pipes, cement, etc. have made the use of polyethylene pipe in water transfer to the first option. Also, poly pipe repair fittings are easier and less expensive than other pipes.
Water supply polyethylene pipes are used to transport and consume water optimally. These pipes help to save water in many areas, including agriculture. These pipes are used for conveying urban and rural water, pressure irrigation, sprinkler irrigation, drip irrigation and drip irrigation. These tubes are manufactured in different sizes, thicknesses, and classes. These pipes are used as the main branches of the water pipes.
What are the different uses of pipes in buildings?
Corrosion and sediment buildup in metal pipes can cause damages and problems in plumbing. So far, many efforts have been made to solve this problem. Using different alloys with different coatings is one of the solutions used so far to increase the corrosion resistance of the metal without any definitive answer to the problem.
Another way to avoid problems with metal pipes is to use polymer pipes, but using these pipes has shown in practice that although replacing metal with plastic solves the problem of corrosion and decay of the pipes, It causes another that did not exist before, such as oxygen diffusion, pressure or temperature limitation, high expansion coefficient, and so on. In this situation, a group of scientists have focused on the synthesis of metal and polymer.
For example, Super Pipe is the highlight of this technology. The clever fusion of a five-layer tube consists of an aluminum tube, two layers of polymer and two layers of special adhesive – which resist corrosion, rust, deposition and decay from polymer tubes and can withstand constant heat, high pressure and It inherits impermeability from metal pipes. Super Pipe is the latest technology breakthrough Hacking is applicable to all building installations and even lives a hundred years in the worst conditions.
History of using pipes in human’s life
In ancient history, when humans were concentrated in one geographical area, the transfer of water from their main sources to cities was necessary for eating, bathing, and other necessities. The first copper-plated ancient artifacts were discovered in the Hindu period. In the past, when paving was done to build a house or a place to live, they began to build a dorky water machine. First, they created canals on the slope of the Rahmat Mountains overlooking the orchard, and built these canals into a large, wide ditch that lay flat on the east wall, so that the mountain rainwater would flow through the ditch into the stream. Head south and north and reach the door.
Thus the danger of houses being destroyed by the current floods from the mountains disappeared, but later this gully became flooded, and the mountain rain flooded most of the eastern buildings and houses, pouring in and destroying the circumcisions. Until some time later, people dug underground waterways that passed through the houses and flooded the ceilings into the underground waterways through the gutters, which were fitted with bricks and mortar bits into the brick walls. Beneath the south wall, there was a plain and a moat.
Is polypipes good for use in gas systems?
In countries where there are natural gas resources since the 1980s, the pipes have been used to transport gas from poly pipes, first to black poly pipe fittings then to yellow pipes or completely yellow pipes, and a few years ago to pipes. The two black walls are used with yellow tube coating. Due to its good mechanical and chemical strengths and lightweight, ease of intubation, welding ability, impact resistance, resistance to corrosive mineral chemicals in the soil and resistance to hydrocarbons and easy transportation and installation polypropylene pipe fittings are the most suitable type of plastic for use in gas transportation. France, for example, has been using HDPE pipes for distribution of the gas system for years. Nowadays, 5 km of pipeline network is 2 km of pipelines and more than 5 km of pipe is added annually to this network.
The amount of gas permeated from poly pipes is negligible due to the wall thickness of the pipes used. Experiments on poly pipes have shown that the amount of gas emitted from poly pipes is less than 1: 1000 compared to other gas outflows in the pipeline. Experiments in gas companies have also shown that the amount of gas emitted from poly pipes per year is so low that it is economically and economically acceptable and, most importantly, does not harm the environment.
What type of water pipes are used in homes today?
Climate change and an increase in the population and temperature of the planet have reduced water resources and the increasing human need for water and food. It is obvious that using polyethylene pipe and abandoning traditional methods can prevent water loss. This pipe prevents evaporation of water, which in turn helps to conserve limited water resources. Proper water management (principally harvesting groundwater resources, water transfer) is important in reducing energy consumption and increasing productivity and production of agricultural products. Limited water resources and conservation for future generations can only be achieved through proper planning and application of new and advanced scientific technologies and technologies in the water and wastewater industry.
Factors Influencing Water Crisis Prevention :
- Modification of consumption pattern with culture
- Replacing modern farming practices with old and traditional methods
- Benefit from the experiences of leading countries in the water, wastewater and agricultural industries
- Use of Fan Experts
- Investment and establishment of agricultural universities in productive areas
One of the newest systems is the transfer of water and sewage and rain and drip irrigation of the fields by polyethylene pipe. They are also used today in homes because of the importance and benefits of polyethylene pipes for plumbing. polyethylene pipe fittings catalogue explains well the size, application and other information of the pipe purchased.
Advantages of PE pipe :
- Great variety
- Long-life up to 50 years
- No rust
- Tension and Strain Tolerance
- No need for solvent
- Resistance to rodent animals
- Ambient temperature resistance from -20 to +50
Therefore, it can be said that the best type of water pipe is polyethylene pipes that are more suitable than other types of pipes.
Safe and best pipes for hot water
These polyethylene pipes have numerous advantages and this is why these pipes are popular all over the world and 90% of water pipes are used especially for hot water polyethylene pipes. Lightweight, ease of installation, convenient transportation, cheap and reasonable price, high resistance to sunlight, high mechanical and chemical resistance, resistant to internal and external pressures such as concrete pressure, impact resistance, resistance to Equivalent to corrosive materials, no leakage, having secure and durable connections, long shelf life, variation in different load pressures, variation in size and thickness, high thermal resistance, cold to negative 70 ° C, resistant Fire, earthquake-resistant and external and internal stresses are important advantages of these pipes.
Polyethylene hot water pipe in branch and coil sizes from 50 to 630 mm (branch length 6 m and 12 m – coil length 100 m and 50 m) with working pressure of 6 atmospheres, 10 atmospheres, 16 atmospheres And 20 atmospheres are produced.
In the new variant of this product, the presence of a layer inside the polyethylene pipe makes the drinking water consumed as 100% hygienic to the consumer.
Polyethylene pipe connection method for hot water from 1 × 1/2 inches to 5 inches using polyethylene screw or butt welded and over 5 inches should be welded with polyethylene flange welding Connected to the head of the pipe and with the rim, washer and bolt to each other and other devices.
It should be noted that when welding polyethylene pipes, the head of the pipe must be perfectly smooth and smooth. Then attach two pieces of polyethylene by gluing the hot iron with the appropriate pressure (depending on the diameter, thickness and material of the polyethylene pipe of choice).
Most famous producing factories of pipes and fittings
It is not easy to make pipes and fittings because of their importance and widespread use and it needs its own specialists. It is important for buyers to provide high quality, affordable pipes. Therefore, knowing the famous factories in the field of pipe and fittings production is very important because the famous factories and companies usually offer better quality products. High quality, reliable pipe and fitting, ease of loading and transportation Due to their weight, quick and easy installation is one of the features of well-known factory products and brands.

Best size of polypipes for water
In hot and cold water piping used to connect the pipes to each other, pipe alignment, bifurcation, or pipe diameter use components called fittings or joints. Joints or joints are manufactured in two types of a screw or (gear) and welding that are exclusively used in cold and hot water piping and white return screws because the use of non-galvanized gear joints is difficult. It causes the pipes to become corroded and thus decay.
The most important water pipes are poly pipes, which are designed according to their application in opposite sizes. For example, a 1 inch poly pipe fitting or a 32mm tube with pressure tolerances varying from 6 to 32 times is produced in 100 to 150 meter sheets. The 1 inch poly pipe fittings are widely used in agriculture and low-flow fluids. So they can’t be used for water plumbing in buildings. So it is important to choose the best size for your intended use.
