The construction inspection of electrofusion saddle welding is mainly visual inspection, including the following:
1. After the electrofusion saddle-shaped pipe fittings are welded to the PPH pipe, no melt should flow out of the pipe fitting surface; a small amount of polypropylene ejection should be seen from the observation hole, but the ejection should not be runny.
2. The fused saddle pipe fittings should be perpendicular to the pipe axis.
3. There should be scratching marks around the welding of saddle-shaped PPH pipe fittings.
4. PPH pipeline construction requires the use of electrical equipment, so pay attention to protecting yourself during construction.
Pay attention to the following during construction:
1. Before using the welding machine to operate, the operator must hold a certificate to work.
2. When using fusion splicing tools for PPH pipe connection, the operating procedures for electrical tools should be followed. The power box and wire connectors should have corresponding protection measures. And equipped with a grounding device.
3. Check the working status of the grounding power distribution protection device once a month, check the equipment regularly, and replace damaged accessories.
4. Fireworks are strictly prohibited on the construction site.
