1. Hot and cold water systems in buildings, including centralized heating systems;
2. Heating systems within buildings, including floor, wall panel, and radiant heating systems;
3. Directly potable purified water supply systems;
4. Centralized air conditioning systems;
5. Industrial piping systems for transporting or discharging chemical media, etc.
Precautions
1. PPR pipes and fittings use a heat fusion connection method, but threads cannot be directly applied to the pipes and fittings. Flanges can be used for connections to metal pipes, and fittings with metal inserts must be used for connections to water appliances.
2. Reliable heat fusion equipment must be used during the heat fusion process to ensure weld quality.
3. When using specialized scissors to cut PPR pipes vertically, ensure the cut is clean and burr-free.
4. The welding area of PPR pipes and fittings must be clean to prevent dust from damaging the joint.
5. When inserting the pipes and fittings for welding, the equipment must heat them for the specified time.
6. Immediately after heating, remove the pipes and fittings for connection. If incorrect positions are found, adjustments can be made within a certain time.
7. After connecting the PPR pipes, hold the pipes and fittings firmly with both hands to allow sufficient cooling time. Release them once they have cooled sufficiently before continuing installation. White PPR pipes should be marked with colored paint on the wall or floor after connection to prevent further damage to the fittings.
