Description of HDPE electric fusion pipe fittings:
HDPE electrofusion pipe fittings include equal diameter straight, reducing diameter straight, flange, tee, elbow, etc.
HDPE electrofusion pipe fittings usually have a socket or spigot that matches the HDPE pipe, and a resistance wire is embedded inside the pipe fitting. The resistance wire is generally distributed in a spiral or grid shape to ensure that it can heat evenly when powered on. The pipeline system is connected by electric hot melting, and the joint strength is higher than the strength of the pipeline itself. The electrofusion pipe fittings are equipped with barcodes. By scanning the barcodes, users can quickly and accurately obtain detailed information about the pipe fittings, including specifications, models, materials, etc., to avoid installation errors caused by human misjudgment.
Working principle: The electrofusion connection is based on the characteristics of HDPE materials that can melt and fuse at a certain temperature. When the electrofusion pipe fittings are powered on, the resistance wire in the pipe fittings generates heat, which quickly heats up the HDPE material at the connection between the pipe fittings and the pipeline to a molten state. Under the action of heat and pressure, the molecular chains of the two diffuse and entangle with each other, and after cooling, a firm overall connection is formed, thereby achieving a sealed and high-strength connection effect.
Features and advantages of HDPE electric fusion pipe fittings:
Thickened material:
thickened treatment, reliable connection, firm and durable, service life can reach 50 years, reliable connection.
Suitable for high-quality plastic-coated copper wire, uniform heating, not easy to break wire.
Good appearance:
one-time molding, beautiful and neat inner wall, no scaling, pipeline head loss is 30% lower than steel pipe; water
flow is smooth. Selected PE polyethylene, stable and reliable material, in line with national drinking water
standard level.
Highly resistant:
Heat-resistant, cold-resistant, wear-resistant and pressure-resistant, commonly
used in HDPE water pipe steel wire skeleton pipe, fire protection pipe, etc.
Convenient construction:
relatively
simple operation, no complex tools and professional skills are required. During construction, just insert the pipe
into the pipe fitting, and then use the electric fusion welding machine for power welding. The welding process has a
high degree of automation and a fast construction speed, which can shorten the project period.
Strong adaptability:
It can be constructed under various environmental conditions, including low temperature, humidity and
other harsh environments. Moreover, for HDPE pipes of different specifications and wall thicknesses, there are
corresponding electric fusion pipe fittings to choose from, which can meet the needs of various pipe
connections.
Safety and environmental protection:
No open flames or harmful gases are generated during the
electric fusion connection process, reducing safety hazards and environmental pollution at the construction site. At
the same time, HDPE material itself is non-toxic and corrosion-resistant, meets environmental protection
requirements, and can be widely used in various fluid transportation fields such as drinking water and sewage.
