As we all know, PP pipe can be used for more than 50 years, but if you don’t pay attention to maintenance, it will definitely not be used for 50 years. So how can we ensure that the PP pipe can be used for a long time, and can ensure that its basic performance is not damaged by external connections? PP pipe is also like a car, it needs maintenance and upkeep. For example, for long-term use, the damaged galvanized air duct should be derusted and painted with rust-removing protection paint. It is necessary to set up a special person to observe the situation of the work place and find out the problem and solve it in time. Once the concealed project is over, it is difficult to ensure that there are various problems in the concealed project.
When dealing with such pipeline problems in winter, it should be done according to the actual local conditions. In winter, when the temperature is too low, the toughness of PP pipe will be affected, and it will be very brittle compared to summer. When bending, we must pay attention to the degree of bending. Generally, technicians in construction will have certain personal experience, and technicians with rich experience can easily grasp it. However, in winter, we should pay attention to the construction of PP pipes, so as to ensure long-term effectiveness. usage of. If the pipeline is buried underground, it must be well prepared for the basic environment, covered with antifreeze materials, well drained, and maintained in a relatively dry environment to prevent the pipeline from being frozen by the external environment, causing problems with the PP pipeline. The flanges and valves connected to the PP pipeline should also be protected, and should be painted with paint of the corresponding color, plus a thermal insulation layer, such as glass fiber cloth, and fire-resistant paint.
The PP pipe itself has the characteristics of insulation, but its protection and anti-corrosion measures must be done well to ensure that it has a longer service life. When the PP pipe is welded, the PP pipe joint and connecting parts should be polished with sandpaper, and if there is grease, it should be wiped with vinyl chloride or acetone. Then connect the welded parts to the welding sleeve, both ends must be inserted into the midpoint of the sleeve, and make sure that there is no water at the two ends of the butt. If the PP pipe joint has scratches, be sure to repair the joint to avoid residues and burrs, and gaps appear during welding.
