The temperature of the PE pipe is generally controlled between 80-100°C

The aging speed of PE pipes will be greatly accelerated in high-temperature environments, not to mention that the dominant temperature will be far above 50°C, so PE pipes are not suitable for hot water transportation. Good heat dissipation means that the thermal insulation effect is also better, but it is used in Hot water piping. The temperature of the PE pipe is generally controlled between 80-100°C. If the temperature is too low, the back pressure will increase, the output will drop, and even accidents may occur that the material cannot be squeezed out and the screw bearing will be damaged.

The PE pipe buried pipeline should not pass through the foundation of buildings and structures. When it must pass through, the foundation should be protected by sheathing pipes. When laying below the low level of the foundation of buildings and structures, it must not be within the range of the diffusion angle under pressure. PE pipe has a smooth inner surface and its Manning coefficient is 0.009. The smooth performance and non-adhesive properties ensure that the PE pipe has a higher conveying capacity than traditional pipes, and also reduces the pressure loss of the pipeline and the energy consumption of water transportation.


When the input voltage of PE pipe welding machine is welding, if the voltage is too low, the terminal voltage of the welding head will also decrease. The power cord of the PE pipe welding machine should not be too long, otherwise it will cause a voltage drop and lead to false welding. Backfilling fine sand or fine clay around the pipe can solve the problem. Genus fusion problems account for two-thirds of all accidents. Among them, there are reasons for unqualified welding quality between pipes and pipes, pipes and fittings.

After grooving, invite relevant personnel including supervisors before installing the lower pipe, and the next process can only be carried out after the owner has passed the inspection of the groove. Sufficient preparation is an important step before construction, so that the subsequent construction of PE pipes will also proceed smoothly.
