After the construction of pe pipes, there are many times when the pressure does not pass, and there is water leakage, so how to avoid these problems? Wanxiong has sorted out some precautions, hoping to help everyone. PVC transparent pipe production line, PVC one-out four-speed production line, high-speed mixer manufacturer

1. Storage and installation environment of PE pipes

It is recommended to take shading measures for outdoor laying in the open air, where there is sunlight.

2. The influence of temperature factors

Buried HDPE water supply pipelines, pipelines with DN≤110 can be installed in a serpentine shape in summer, and pipes with DN≥110 can resist thermal stress due to sufficient soil resistance, so there is no need to reserve pipe length; in winter, there is no need to reserve pipe length. tube length.

3. Construction space factors of pe pipe production line

When installing HDPE pipes, if the operating space is too small (such as pipeline wells, construction in suspended ceilings, etc.), electrofusion connection should be used.

4. Operating procedures for hot melt sockets of pe pipes

When welding socket and socket connection, the heating temperature should not be too high or too long, and the temperature should be controlled at 210±10℃, otherwise it will cause too much molten slurry extruded in the fittings and reduce the inner diameter of the water; It should be clean, otherwise it will cause the socket and socket to separate and leak; at the same time, pay attention to control the angle and direction of the pipe fittings to avoid rework.

5. Operating procedures for hot melt butt joint of pe pipes

When the hot-melt butt connection is made, the voltage is required to be between 200 and 220V. If the voltage is too high, the temperature of the heating plate will be too high, and the voltage will be too low, and the docking machine will not work normally; the docking interface should be kept aligned when docking, otherwise it will cause The butt area is not enough, the strength of the weld is not enough, and the curling is not aligned;

When the heating plate is heated, the joint of the pipe is not cleaned, or the heating plate has impurities such as oil, sediment, etc., which will cause the joint to be disconnected and leak water; the heating time should be well controlled, the heating time is short, and the heat absorption time of the pipe is not enough, which will cause welding joints. If the curling edge is too small and the heating time is too long, it will cause the welding seam curling edge to be too large, which may form a virtual welding.
