What should be noted when welding PE pipes in summer?

1. Check whether all components of the welding machine are functioning properly, paying special attention to measuring the temperature of the heating plate before use to ensure it falls within the standard range (220℃ ± 10℃). 2. When adjusting the heating plate temperature, take into account the impact of ground temperature and ambient temperature on the actual temperature of the heating plate, and prevent the actual temperature of the heating plate (ground temperature + ambient temperature + displayed heating plate temperature) from exceeding 230℃. When the ambient temperature is above 38℃ and construction is carried out on asphalt roads, the heating plate temperature can be adjusted between 190℃ and 200℃; when the ambient temperature is below 38℃ and construction is performed in the field, the heating plate temperature can be adjusted between 200℃ and 210℃. 3. Before joining pipes, check the misalignment rate. The misalignment rate should not exceed 10% of the pipe wall thickness. If the misalignment rate exceeds 10% of the pipe wall thickness, the contact area at the weld joint will be smaller than the pipe wall thickness, thereby affecting the welding quality.

2. When adjusting the heating plate temperature, it is necessary to take into account the impact of surface temperature and ambient temperature on the actual temperature of the heating plate, ensuring that the actual temperature of the heating plate (surface temperature + ambient temperature + displayed heating plate temperature) does not exceed 230℃. When the ambient temperature is above 38℃ and construction is carried out on asphalt roads, the heating plate temperature can be adjusted to between 190℃ and 200℃; when the ambient temperature is below 38℃ and construction is performed in the field, the heating plate temperature can be adjusted to between 200℃ and 210℃.

3. Before joining pipe sections, check the misalignment rate. The misalignment rate should not exceed 10 percent of the pipe wall thickness. If the misalignment rate exceeds 10 percent of the pipe wall thickness, the contact area at the weld joint will be smaller than the pipe wall thickness, thereby affecting the welding quality.
