Normally it is 260 degrees to 280 degrees. When the pipe is hot-melting, the temperature must be controlled within this range, neither too high nor too low, which will affect its hot-melting effect. For example, the pipes will not be completely fused together, or the excessive fusion will cause deformation and other phenomena, which will cause leakage and other phenomena.

Properties such as high pressure and temperature resistance, durability, and corrosion resistance. One of the essential factors that determine the performance of PPR pipes is their melting temperature.
The melting temperature of PPR pipes depends on several factors, including their composition, thickness, and pressure rating. Generally, PPR pipes have a melting temperature of around 260°C - 280°C (500°F - 536°F), which is much higher than other plastic piping systems such as PEX or PVC. This high melting temperature ensures that PPR pipes can withstand high-pressure hot water and steam applications without any deformation or degradation.
Additionally, PPR pipes are manufactured through extrusion or injection molding processes, which further enhance their melting point and structural integrity. During these manufacturing processes, the plastic resins used to make PPR pipes are heated to a high temperature, melted, and then molded into the desired shape. This way, the PPR pipe's molecules are tightly bonded, resulting in a homogeneous and robust material that can withstand extreme heat and pressure.
In conclusion, the melting temperature of PPR pipes is an essential factor that determines its performance in plumbing and HVAC applications. With a high melting point, PPR pipes can withstand high-pressure hot water and steam applications, making them one of the best choices for plumbing and HVAC systems.
