Installation Steps for Electrofusion Fittings

　　Installation Steps for Electrofusion Fittings

　　1. Cut the pipeline 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 material surface.

　　2. Based on the socket depth of the fuse tube, use a marking pen to draw a mark line on the tube’s surface.

　　3. Insert the pipe. Electrofusion Fittings Depth to the marking line. After installation, the pipe axis shall coincide with the electrofusion fitting.

　　4. Use fixtures to secure the pipes and pipe fittings to prevent misalignment and loosening during welding.

　　Precautions

　　1. During installation, the inner walls of electrofusion fittings and the pipe material in the welding zone must be kept free from contamination by organic substances or other pollutants.

　　2. When welding pipe fittings, keep a safe distance from the fitting being welded; only approach once welding is complete and the fitting has cooled for 30 seconds.

　　3. Based on the site conditions, temperature, and operating voltage, the welding time may be appropriately adjusted during welding.

　　4. Connect a matching power supply in accordance with the welder’s requirements. The farther the power supply is from the electrofusion welder, the larger the diameter of the power cable should be, to prevent voltage drop from compromising the quality of the welding operation.

　　5. During pipeline installation, bends and tees shall be reinforced with buttresses or secured with supports, and appropriate compensation shall be provided for the pipeline.

　　6. The pipeline shall be buried below the permafrost layer, and during trench installation and welding, the pipeline must not be allowed to become submerged in water.

　　7. Welding at lower temperatures Electrofusion Fittings Ensure proper insulation.

　　8. When working in environments with large diurnal temperature variations, use alignment tools and other fixtures to secure the pipe fittings on both sides of the electrofusion fitting, so as to prevent thermal expansion and contraction from compromising weld quality.

　　9. During the cooling process, piping and pipe fittings must not be moved.

　　Points to note during the installation of electrofusion fittings:

　　1. First, during installation, the inner walls of the fusion pipe and the welding area must be free of organic matter and contaminants. In addition, during the welding process, it is essential to maintain a safe distance from the equipment to prevent unnecessary damage.

　　2. The buried section of the electrofusion fittings shall be located below the permafrost layer. It should be noted that the pipeline must not be submerged in water during installation and welding.

　　3. In harsh environments with large diurnal temperature variations, stabilizers and other pipe-fixing devices should be promptly installed to prevent thermal expansion and contraction from compromising the quality of the final weld; furthermore, when temperatures are exceptionally low, thermal insulation measures must be implemented to avoid unnecessary losses.

　　4. Finally, during the cooling process of the pipeline, it must not be moved arbitrarily.

　　PE Electrofusion Fittings Detection method:

　　The test method for polyethylene melt pipes is elongation at break. Elongation at break is a key indicator of pipe flexibility. By determining the elongation at break across various pipe grades and comparing the results, it can be confirmed that the pipes retain certain properties of the raw materials, thereby ensuring ease and cost-effectiveness of installation, enhancing the pipe’s ability to accommodate differential settlement caused by uneven foundation conditions, and meeting the performance requirements of seismic-resistant building design.

　　Weather Resistance: Under the combined effects of natural climatic factors such as sunlight, temperature fluctuations, wind and rain, and atmospheric oxygen, the strength, thermal stability, and elongation at break of the piping all decrease. Through testing the weather resistance of bamboo-based materials, it has been confirmed that the pipe material retains the properties of the raw material, ensuring that, even after receiving positive evaluations for its performance, the system piping can still meet the technical requirements for industrial applications.
