1.When installing PP pipe, the influence of ambient temperature on the quality of the device should be considered. Generally, when the temperature is higher than 40°C or lower than 0°C, the installation should not be constructed.
2.Due to the large expansion coefficient of the PP pipeline, thermal compensation should be considered during installation, generally based on natural compensation, such as the selection of square expansion joints.
3.When the PP pipe is laid overhead, the pipe should be supported by the pipe support, and the pipe support can be made of angle steel, steel pipe and other materials, so that the reinforced polypropylene can be freely stretched on the pipe support.
4.When the PP pipe needs to be hidden. It is recommended to use pipe trenches for laying. The pipes are generally welded and connected. If they need to be buried for special reasons, they should be directly buried in the form of casing to prevent the backfill soil from being mixed with hard debris and breaking the pipes.
5.When the PP pipe is connected with flanges, it should be strictly centered. The maximum allowable error in the axial direction is not more than 2mm. The method of forcibly tightening the bolts should not be used for adjustment. The bolts are tightened twice, and the first time is symmetrical diagonally Twist again, then tighten the bolts again.
