How HDPE pipes are joined?
Polyethylene fittings by heat welding or mechanical fittings
Since polyethylene is a thermoplastic material, polyethylene pipes and fittings can be produced simultaneously using heat and pressure, and by using heat-welding processes at temperatures above the melting point of contact surfaces, polyethylene pipes can be made to It constantly boils. Polyethylene pipes or joints are welded together with heat welding or mechanical joints. Polyethylene pipes can be connected to other pipes using pressure connections, flanges, etc. The user has a variety of connections to choose from. Each of these connections has its own advantages and disadvantages in the particular connection conditions that the user faces.
When connecting polyethylene pipes to fittings, it is important to first determine the standard fittings and connections, then use standard fittings to connect, and finally the method of connection by the contractors is correct. The equipment used to perform the welding process must be specially designed to work with the pipe and the welding instructions. In addition, equipment must be well maintained and capable of operating in accordance with the technical specifications stated.
PE pipe connection by butt welding or BUTT WELD method
This type of PE pipe connection is also called thermal bonding in which the two ends of the PE pipe are heated simultaneously before bonding. During the heating and cooling phase, the timing and mechanical parameters of the PE pipe must be observed.
Electrofusion welding differs from heat fusion fusion. The main difference is in the method of heating the junction. In the fusion welding method, heat is one of the thermal tools for heating the joint. In the fusion welding method, heat tools are used to heat the pipe surface and PE connections, but in electrophysical welding heat is generated by electric current inside. In polyethylene pipes, the welding resistance created by the electro-fusion method is higher than that of the weld.
Electrofusion welding is a type of welding of polyethylene pipes and fittings in which special joints with electrical resistance wire are used to create the heat of melting of the welding surfaces. The electric current is transmitted to the two ends of the connector by means of an electro fusion welding machine and by means of a control box. Like heat-melting welding methods, different types of saddle and socket joints are also used in the electrofusion method. The principles of the electrofusion process are uniform and generalizable to most electrofusion joints.
PE pipe connection by extrusion welding
This method is usually used to connect polyethylene pipes larger than 5 mm in size, to attach polyethylene pipes to humans and to make hand-made joints.
First, the double-sided edges or polyethylene pipes and fittings are heated by a hair dryer, then injected into the edges with a hand-held extruder for polyethylene fuels, feeding the material in a wire-like manner with the help of a special spatula. In this method the skill and accuracy of the welder is important.
Extruder welding is the best method for sealing polyethylene pipes in terms of sealing and mechanical strength, but it is longer than other methods and does not apply to small diameter PE pipes.
Threaded fittings are used for small tubes (one eighth to five inches in diameter). The thread is available in tubes up to 5 inches nominal diameter. There’s also a larger thread cut, but it works with gear conversion and requires a lot of manpower. Since the yarn fittings are by machine or by hand. Manufacturer’s recommendations should be followed carefully.
Popular uses of PE pipes
Due to its unique characteristics, polyethylene pipes are widely used in large-scale industrial fluid transfer projects that can distinguish them from other pipes. These types of PE pipes are nowadays a good choice for water, municipal and industrial wastewater, gas transmission pipe.
Other PE applications:
- Transmission lines for petroleum products
- Fluid lines in factory processes

all about pipes and their different coupling fittings
Tubes can be of different types in terms of sex, use and fitness.
The pipes used in the water supply and sewage systems are as follows.
Galvanized steel pipes are divided into two categories: galvanized steel pipes and galvanized iron pipes These two types are known in the market as white iron pipes and generally do not differ between the two, with galvanized steel pipes being the type. Its iron is lighter and shiny.
1. Galvanized steel pipes:
These pipes are sometimes used to drain small sanitation but are primarily used for ventilation. The pipes are made of soft stainless steel, where they are welded to a steel plate by pressing into the die and then sealed to increase the resistance to acids and rust in a galvanized tub. These pipes are less resistant to acids than ferrous metals, and all harmful acids for cast iron are also made from galvanized steel.
2. Galvanized iron pipes:
The pipes are made of white iron that are welded together by seam welding and then immersed in molten metal. That’s why they are also called integrated pipes. These tubes are known for their dark gray color and are generally produced in both light and medium form.
Cast iron pipes:
These pipes are made of cast iron and vary depending on their application, type and amount of alloy, shape and length of fittings and are often used in sewage systems.
- Plastic pipes used in water and wastewater installations include:
- PVC Plastic Pipes (PVC – Poly & Nile Chloride Stands)
- Plastic pipes (PE stands for polyethylene)
- ABS plastic tubes (acrylonitrile, butadiene and styrene)
- PP plastic pipes (polypropylene stands)
- CPVC Plastic Tube (stands for Poly Chloride and Nile Chloride)
- PB Plastic Pipes (Polyethylene Booths)
Five layer pipes:
Corrosion and deposition in metal pipes can cause damage to the piping. Many efforts have been made to solve this problem. Various alloys have been used in solutions that have been used to increase corrosion resistance of metals without definitive response to the problem.
Another way to prevent problems with metal pipes is to use polymer pipes, but the use of these pipes has shown in practice that although replacing metal with plastic solves the problem of corrosion and decay, it causes another to exist. It didn’t, like the release of oxygen. , Pressure or temperature tolerance, high expansion coefficient and so on.

Identification quality of PE pipe fittings
Due to the many benefits that have been said for years for the use of PE pipes in irrigation, these pipes have been used in agriculture for many years. How much irrigated land and farmland because the country’s water resources are severely endangered and dramatically reduced. As you know, the old agricultural water supply systems had some problems that caused a lot of wasted water. For example, water that passes through pipes to irrigate agricultural fields drains out of the pipes and agricultural lands are not properly irrigated. To solve such problems, polyethylene pipes were designed and manufactured for irrigation. Fortunately, the use of these durable plastic pipes saves water consumption while also providing more complete and useful water to the plants. It is good to know that the main feature of the PE agricultural water supply is the blue strip on the outer wall of the pipe. Polyethylene pipe has many features compared to other pipes available in the Iranian market:
- Cheap PE pipe compared to other pipes
- Polyethylene pipes have no effect on water and liquids
- The ability to sweep a large portion of the yarn, which increases the speed of installation, requires fewer connections
- The inner surface of the polyethylene pipe is smooth and polished and the deposition in this type of pipe is very low.
- Impact-resistant, corrosion, rot, abrasion, cracking
- High flexibility
- Long and long life
Compression fittings for polyethylene pipes
Due to its special features, these types of pipes are very effective if used correctly, and can be used for many years. As mentioned, the PE pipes are very flexible and can bend up to 5 times the diameter of the pipe. Usually, it is not very suitable in areas where the land recedes or landslides and is not fixed. In these types of soils other pipes may be slightly damaged or broken, but these pipes can be used without any changes. This pipe is connectable with a variety of connections. These connections are very durable and often have no problem with this.
Newest technologies for producing pe pipes and fittings
The production of high-tech polyethylene pipes of various sizes eliminates the need for precise pipe selection. Agencies and factories supply PE in various ways throughout the country and can be purchased in all provinces and cities of Iran. Iran is one of the manufacturers of polyethylene pipes in the Middle East that has exported some of its products so that some neighboring countries are the best foreign customers for these pipes. Neighboring countries with a common border with Iran and the Gulf states are among the buyers of manufactured pipes in Iran.
Best and safest pipes for drinking water
The five-layer pipe is one of the most widely used construction pipes that can be used for a variety of purposes. Note that these pipes are not only used in homes or buildings. But given the widespread use of pipes in buildings, what has been the focus of buyers these days is their use in residential and construction activities.
5 layer pipe can be used in different conditions. But their most important uses, which generally relate to buildings, are:
- Using a five-layer pipe for the use of potable or hygienic water systems in residential or commercial buildings
