What are the characteristics and testing methods for electric fusion pipe fittings?

Electrofusion fittings are plastic (polyethylene) pipe fittings that are joined by the heat generated through electric current. The rated current (i.e., amperage) is the primary parameter. In certain low-voltage circuits where voltage requirements are not stringent, only the amperage rating is specified.

What are the basic principles of electric fusion fittings?

Electrofusion fittings feature a large-radius transition, effectively reducing water pressure. Under conditions of thermal expansion and contraction due to temperature changes, the fitting’s unique curved design naturally accommodates axial expansion and contraction movements of the pipeline, providing sufficient axial displacement capacity to accommodate thermal expansion and cold shrinkage.

Precautions for connecting electrofusion fittings: How to assess product quality?

Simply put, electrofusion fittings are a type of pipe fitting made from plastic that is joined by the heat generated through electric current. They can be used to connect small-diameter pipes or small bends. The exact shape of electrofusion fittings varies, as they are manufactured to meet specific customer requirements.

Characteristics of Polyethylene Electrofusion Fittings

In the sales and application of polyethylene pipeline management systems, fittings account for approximately 15% to 20% of total sales. Polyethylene pipeline system fittings are mainly categorized into hot-melt fittings and electrofusion fittings. Due to their cost-effectiveness, they are widely used in engineering applications. Hot-melt fittings are consumed in greater quantities than electrofusion fittings; however, electrofusion fittings play an irreplaceable and critical role in both new construction projects and maintenance work. In particular during installation, electrofusion fittings are less susceptible to external environmental conditions and human error, resulting in higher reliability and greater user acceptance.

Installation Steps for Electrofusion Fittings

1. Cut the pipe of the vertical cutting system, insert the spigot into the socket of the electrofusion fitting, and use a scraper to remove the oxidized layer on the pipe surface. 2. Based on the insertion depth of the electrofusion fitting’s socket, use a marking pen to draw a reference line on the pipe surface. 3. Insert the pipe into the electrofusion fitting until the reference line is reached. After installation, ensure that the pipe axis aligns with the axis of the electrofusion fitting. 4. Use clamps to secure the pipe and fitting to prevent misalignment and loosening during the welding process.
