The ideal environment for Polyethylene (PE) pipe is one where the temperatures stay at about 41 degrees Fahrenheit. While you can perform electrofusion welding operations at temperatures below 41 degrees, you may run into trouble ensuring there is no moisture, which is vital to stave off contamination. During the PE pipe welding process, time is highly critical. A maximum of thirty minutes should go by once scraping is done, or else the risk of pipe oxidation is amplified. PE pipe that has oxidized will not weld properly.
As for electrofusion fittings, it’s best to keep them in their bag until it’s time to weld. Fittings that have been removed from their bag for over thirty minutes may experience oxidation. Oxidation may happen in an unsuccessful joint, which means a potential loss of time and money.
If you’re worried your pipe may be ruined because of the exposure to the harsh ultraviolet rays of the sub, you may wish to look into the groundbreaking Fusion-Tech UV Black Piping by aquatechnik NA. This fusible polypropylene pipe has UV protection built into it which provides maximum pressure handling and temperature capabilities.
