PVC/CPVC Pipeline Construction And Installation Methods-safety Common Sense

Do not use thermoplastic tubes to transport compressed air or gas. Exhaust the gas trapped in the pipeline. When the pressure increases, make sure that no gas is trapped in the pipeline. When the flow rate of the liquid in the pipeline is maximum and the valve is suddenly closed, the water hammer pressure reaches its maximum. To prevent excessive water hammer pressure, the maximum liquid velocity is usually 1.5 meters per second.

There are usually conditions where the pipe and fitting are connected. For example, some parts of the wall thickness of the threaded connector are very thin; improper bonding makes the connection force of the pipe insufficient.
