Note on Yonggao PPR Pipe Material:
1. PPR pipes and fittings are connected using hot melt methods, but cannot be threaded directly onto pipes and fittings.法兰 connections can be used when connecting to metal pipes, and fittings with metal inserts are mandatory for connections to water appliances.
2. Always use a reliable hot melt equipment during the hot melt connection process, as it ensures welding quality.
3. When using scissors to cut PPR pipe material vertically, ensure the cut is smooth with no burrs.
4. Ensure the welding areas of PPR pipes and fittings are clean to prevent sand and dust from damaging the quality of the joints.
5. During welding, the equipment must heat the pipes and fittings in accordance with the prescribed time.
6. Immediately remove the pipes and fittings after heating is complete for connection. If you find that these positions are incorrect, you can make the corresponding adjustments within a certain time frame.
7. After PPR pipe connection, the pipe and fittings must be tightly gripped with both hands to ensure sufficient cooling time. Once cooled to a certain extent, release and proceed with the pipeline installation. After completion, mark the pipeline location on the wall or floor with colored paint to prevent further damage to the fittings.
