Advantages of Electrofusion Welded Pipe
Increased accuracy: One of the primary advantages of electrofusion welded pipe is that it is a very accurate welding method. This is due to the fact that the weld joint is heated very evenly, which prevents warping and distortion.
Increased speed: Another advantage of electrofusion welded pipe is that it is a very fast welding method. This is due to the fact that the weld joint is heated very quickly, which reduces the overall welding time.
Increased strength: Electrofusion welded pipe also results in a very strong weld joint. This is due to the fact that the weld joint is heated very evenly, which prevents weak spots from forming.
Reduced costs: Electrofusion welded pipe can also help to reduce costs associated with welding. This is due to the fact that electrofusion welded pipe does not require the use of expensive equipment or consumables.
Increased safety: Electrofusion welded pipe also offers increased safety compared to other welding methods. This is due to the fact that electrofusion welded pipe does not produce harmful fumes or sparks.
Application of Electrofusion Welded Pipe
Water supply systems
Ideal for potable water applications where hygiene and quality are paramount.
Gas distribution
Commonly used in natural gas pipelines, ensuring strong joints that can withstand pressure.
Wastewater management
Preferred for sewage and drainage systems due to its resistance to corrosion and harmful chemicals.
Mining and industrial processes
Utilized in industries where durable pipes are required for transporting chemicals and other harsh materials.
Installation Safety Precautions of Electrofusion Welded Pipe
Prioritize safety by wearing appropriate personal protective equipment (PPE), including gloves, safety glasses, and protective clothing.
Verify that all welding equipment, including the electrofusion machine, welding cables, fitting, and pipes, are clean, undamaged, and in proper. Select a flat, stable work surface free from moisture, dirt, and debris. Ensure proper ventilation in indoor environments.
Production Process of Electrofusion Welded Pipe
Electric resistance welding can be divided into two kinds:resistance welding and induction welding. ERW pipe is cold formed into a cylindrical shape rather than hot formed. An electric current rather than a flame is used to heat the edges of the strip for the fusion weld. Revolving copper discs serve as electrodes and raise the temperature to about 2600°F for effective welding. Different from longitudinally Submerged Arc Welding,Usually ERW uses AC with frequency from 100 to 800 kHz, or 100.000 to 800.000 cycles per second.
This process is characterized by two effects: skin effect, or concentration of high-frequency current on the surface,and proximity effect when a high-frequency concentrates on the two adjacent parallel inner edges in the welded wedge, before the welding point. These effects allow a welding process to take place with the least amount of heat released, and because of that the structure of the basic material changes in a relative small zone around the central – ferit line of welds. Scavenging melted material from inner and outer side of the weld is removed by scraping devices.
