1. Check the pipe and electrofusion sleeve for damage.

2. Remove debris and align the pipes.

3. The pipes to be joined should be placed 20-750 pixels above the ground using a horizontal bar or sandbags. If there is an operation pit at the base, the pipes can be placed directly on the base. The operation pit width is twice the width of the electrothermal fusion, the depth under the pipe is 750px, and it is horizontally aligned.

4. A clean cloth base is used to thoroughly remove foreign objects (including water vapor) from the outer surface of the pipe and the inner wall of the electro-heat fusion sleeve. Oil stains can be scrubbed with a solvent that aids in the welding of polyethylene materials.

5. The pipe sections to be joined should be horizontally aligned and clamped with the electro-heat fusion sleeve, and secured externally with heat-resistant tape or clamps.
