Polyethylene electrophurge joints Pars Ethylene Kish

Electrofusion connections are types of connections that can be used in gas transmission pipelines and water supply lines. In electrofusion joints, the heating method is compared to the butt fusion welding methods, and electric current is used to generate heat. Due to its high safety, this method is the only type of connection approved by the IGS standard for gas transmission lines. Using this method, it is possible to make different polyethylene connections such as pipe-pipe, pipe-elbow, pipe-bush (for example, when changing the diameter of the pipeline) and … created Therefore, the polyethylene butt welding method does not have the limitation of connecting pipes with similar sizes. Also, experience has shown that it is possible to connect polyethylene pipes with different types of polyethylene in this method. In addition to its safety, another advantage of this method is high speed and clean connection. But on the other hand, its limitation is the high cost and the maximum diameter of the pipe that can be connected. 

Pars Ethylene Kish Company is the exclusive and official representative of FOX Fittings Europe in Iran and the Middle East. FOX Fittings is one of the leading manufacturers in the field of producing all kinds of electrofusion fittings in Europe and other parts of the world, the electrofusion fittings and products of this company are used all over the world due to their high quality. FOX Fittings provided by Pars Ethylene Kish includes all types of couplers, 90 and 45 degree elbows, equal and unequal tees, conversions, caps and saddles, etc. . . and are produced in different sizes.

Electrofusion welding is different from butt fusion welding. The main difference is in the method of heating the joint. In the thermal fusion welding method, thermal tools are used to heat the surface of polyethylene pipes and fittings, but in electrofusion welding, heat is generated internally through electric current. In polyethylene pipes, the strength of the weld created by the electrofusion method is higher than that of butt fusion welding. Electrofusion coupling is one of the common connections for connecting two polyethylene pipes to each other.

Electrofusion polyethylene joints
Electrofusion welding is a method of welding polyethylene pipes and joints, in which special joints with electrical resistance wires are used to generate heat to melt the welding surfaces. , is used. The electric current is transferred to the two ends of the connection through the electrofusion welding machine and with the help of its control box. Like the methods of thermal fusion welding (butt), all kinds of saddle and socket joints are also used in the electrofusion method. The principles of the electrofusion welding process are the same for most electrofusion joints and can be generalized. The price of electrofusion fittings is included in the price list of polyethylene fittings, and it is at the top of this list, and because these fittings are imported, their price in the list has a direct relationship with its rate and fluctuations in the market.

Advantages of electrofusion joints

• High safety and removal of obstacles and repairs
•  Ease, speed of action and save running time
• High chemical resistance
• High flexibility and lightness
• Protected against corrosion
• resistance to pressure and impact
• Ease of installation that prevents the possible error of the operators
• Elimination of gas and water waste in gas and water supply networks
• Smooth welding surface
• ease in cleaning
• Preventing pollution from entering the welding area
• Preventing obstacles and damages

Electrofusion welding includes the following steps:

• Preparation of the pipe, removal of impurities and cleaning of pollution
• Marking the connection point on the pipe and rubbing the pipe surface
• Aligning and re-stressing the pipe or joint
• Cooling and unclamping
• Process documentation
• Final payment and cleaning and decontamination

In the operation of electric welding, it is necessary to observe the following points:

1.   The heat distribution should be uniform throughout the welding.
2.  The temperature and pressure of the melted part should be carefully controlled.
3.   Prevent damage to the coil of the coupler.
4.  Necessary protection before, during and after connection is necessary.
5.   Consider the right time for electrofusion.
6.  The pipe should be cut perpendicularly to its axis and the roughness should be cleaned with smooth sandpaper and the ends of the pipe.
7.  Clean any kind of dirt from the pipe.
8.  Prepare the connecting piece on site and inspect it for cleanliness.
9.   Clean the shaved part of the pipe with suitable materials. (such as isopropanol)
10.  According to the required characteristics in terms of voltage and welding time, the necessary controls should be carried out.
11.  The connection system will remain inside the clamp until it is fully clamped.

Building the market as a complete reference is the first and only specialized system of the construction industry in the country. Buyers can refer to the market construction system to view the prices of various construction products. The market building system has facilitated the process of purchasing construction products for buyers by establishing direct relationships with manufacturers and sellers. The products available in the market manufacturing system have valid standards and certificates.

Manufacturers and suppliers can register in the market construction system and participate in the special sales festival by placing construction products and inserting the suggested price and increase the sale of their products.
