1. PPR pipes and fittings should be stored in well-ventilated warehouses or simple sheds. They should not be stored in the open air to prevent direct sunlight. Pay attention to fire safety. The distance from the heat source should not be less than 1 meter.
2. PPR pipes and fittings should be stacked horizontally on a flat ground. Bending pipes should be avoided. The stacking height should not exceed 2.0 meters. Pipe fittings should be stacked layer by layer and should not be stacked too high.
3. When handling PPR pipes and fittings, they should be handled with care to avoid oil contamination. Violent impact, contact with sharp objects, and throwing, falling, rolling and dragging are strictly prohibited.
4. Do not hit PPR pipe fittings with hard objects, especially at lower temperatures.
5. The pipe must be cut perpendicular to the pipe axis, and the incision must be kept clean and flat.
6. The hot-melt connection should be connected in strict accordance with the specified welding depth.
7. The hot-melt connection shall be carried out in strict accordance with the specified welding time.
8. During hot melt connection, the maximum deviation between the pipe and the fitting shall not exceed 5°.
9. When the pipe is bent, the bending radius shall not be less than eight times the diameter of the pipe, and it is strictly forbidden to heat and bend with an open flame.
10. The metal thread is designed with tapered thread, and can be sealed with hemp or raw material tape when connecting, and it cannot be over-tightened.
11. When two pipes are overlapped, a curved pipe must be used.
