Polyethylene Electro Fusion Fittings
Electro fusion fittings are a variety of fittings that can be used in gas pipelines and water supply lines. Electro-fusion joints area heat treatment method compared to butt fusion methods and are used to generate heat. Due to its high immunity, this method is the only type of connection approved for IGS standard for gas transmission lines. Using this method, different polyethylene connections can be made, such as pipe-tube, tube-knee, tubebush (for example, in the change in pipe diameter), and so forth. Therefore, there is no limit to the polyethylene bottle boil method for connecting tubes of the same size. Also, the experience has shown that the connection pipes various types of polyethylene are also available in this method. Along with its safety, the other benefits of this method are connectivity at high speed and cleanliness. But on the other hand, the limitation of this method at high cost and maximum diameter of the pipe can be connected with this method.

Electro fusion welding is different with the butt fusion method. The main difference is in the heating method of the joining site. In the fusion welding method, heat treatment is used to heat the pipe surface and the polyethylene joints, and Lee is used for Electro fusion welding Heat is generated internally and through an electric current. In polyethylene pipes, the Electro fusion welding boost is more than the head-to-head fusion welding. Electro fusion oscillations are commonly used to connect two polyethylene tubes to each other.
Electro fusion welding is a type of pipe welding and polyethylene fittings, in which there are special connections that have electrical resistance wire to create welding melting temperatures. The electric current is transmitted through the electro fusion welding device and through the control box to the two ends of the connection. Like the thermal fusion welding (butt), a variety of zinc and socket fittings are also used in the Electro fusion method. The Electro fusion boiling process principle is the same for most electro-fusion joints.
Advantages of Electro fusion Fittings
• High safety and removal of obstacles and repairs
• Ease and quickly operate in runtime and save time
• High resistance to earthquakes and environmental stresses
• High chemical resistance
• Flexibility and lightness
• Immune to corrosion
• Pressure and impact resistance
• Ease of installation, which prevents possible errors from the executives
• Eliminating gas and water waste in gas supply and water supply networks
• Smooth welding surface
• Ease of cleaning
• Avoid penetration into the welding area
• Avoid obstacles and damage
Electro fusion welding involves the following steps:
• Preparing the pipe for removing sprouts and cleaning the contaminants
• Mark the connection on the pipe, rubbing the pipe surface
• Align, re-apply strain on pipe or connector
• Applied electrical current
• Cooling, opening clips
• Documentation of the process
• Final payment, cleaning and removal of contaminants
In the electric welding operation, it is necessary to observe the following points:
1 – Heat distribution uniformly during boiling.
2. The temperature and pressure of the melted part must be carefully controlled.
3. Avoid damaging the coil of the coupler.
4. The necessary protection before, during and after the connection is necessary.
5. Consider the time to Electro fusion
6. The tube is cut perpendicular to its axis and the roughness is cleaned with a flat sheath and a tube duct.
7. Clean any dirt from the pipe.
8. Make a connection piece in place and check for cleanliness.
9 – Shaved parts of the pipe should be cleaned with suitable materials. (Such as isopropanol)
10. For each connection of this type, the use of the clamp is necessary to maintain the connection set.
11- Due to the characteristics required in terms of voltage and welding time, necessary controls are required.
12 – The connection system inside the clamp until it remains fully seamless.
Connection of two tubes using electro fusion joints
In this type of connection (Electro fusion welding), a variety of connectors (electro-fusion coupler ) is used. The couplers are, in fact, polyethylene pieces in the form of a pipe or connection, in which the thermal element is located, and the two ends of the element are connected to the power supply. First, the coupler includes a pair of tubes or joints that are supposed to be connected to each other. Then the two heads of the coupler are connected to the current and the plastic melts it. The created heat melts both ends of the connection and eventually the coupler covers the two ends of the head. After cooling down, the coupler metal clips are removed from the pieces.
