When the pp square pipe is installed, if the operating space is too small, the electrofusion connection method should be used. When the pp square pipe is connected by hot-melt socket, the heating temperature should not be too high, and the temperature should be controlled at about 210 °C, otherwise there will be too much molten slurry extruded in the fitting, reducing the inner diameter of the water. It should be clean and clean; at the same time, pay attention to the viewpoint and direction of the pipe fittings to avoid rework. When the hot-melt butt joint is connected, the voltage is required to be around 220V, and the butt joints should be kept aligned during butt joints, otherwise the joint area will not be required, the welding joint strength will not be good, and the curling will not be matched.
When the heating plate is heated, the pipe interface should be cleaned, and the heating time should be controlled properly. FRPP pipe is a new type of environmental protection pipe, and its indicators are superior to traditional drainage pipes, representing the future development direction of drainage pipes. The pp square pipe should be stacked horizontally on a flat ground, and the twisted pipes should be avoided. The stacking height should not exceed 1.5m. The pipe fittings should be stacked layer by layer, and should not be stacked too high. The pp square pipe should be placed in a well-ventilated warehouse or a simple shed. It should not be stored in the open air, avoid direct sunlight, pay attention to fire safety, and the distance from the heat source should not be less than 1m.
When transferring the pp square tube, it should be handled with care, avoid oil pollution, prohibit violent impact, and prohibit touching and throwing, falling, rolling and dragging with sharp objects. In the construction process of pp square pipe, it is necessary to ensure that the supplied pipes and fittings meet the design regulations, and are accompanied by product instructions and quality certificates. Before use, the FRPP pipe must be technically identified or re-inspected to prevent the use of pipes with different quality and signs of damage. The difference in the laying form of pp square pipes has resulted in two installation methods: elastic joint setting and pipe sleeve setting.
The pp square pipe is determined according to the corresponding conditions during the installation and construction process. The straight pipe must be cut with a pipe cutter first, and the socket must be very flat. The part of the socket end pierced into the electric welding sleeve must not have more than 1mm scratches or deformation. The used welding sleeve should not be used again. If the welding sleeve is damaged or deformed, it should be put aside and not used. If the connection fails, it should be replaced with a new electric welding sleeve and re-welded. If the electric welding sleeve fails due to the interruption of the power supply during the process, it will be completely cooled before plugging in the secondary wire and re-welding.
