PPSU PEX Fittings Are Widely Used In Industrial Production

　　PPSU PEX fittings are widely used in industrial production and our daily life, especially the transportation of domestic water. However, as the use time increases, water leakage will occur. If the cause is not found and solved in time, it will cause a waste of resources.

　　PPSU PEX fittings are commonly used pipes in industrial production at present. Although this product has many advantages and simple operation and use, it is not free to use, but must follow certain usage requirements.

　　(1) PPSU PEX fittings are suitable for the long-term temperature of the medium, not more than 45℃.

　　The above phenomenon is prone to occur due to insufficient temperature of the heating plate or excessive butt pressure.

　　5. Touch the end face after milling by hand

　　Intentionally and accidentally touch the milled end face before welding in PPSU PEX fittings, resulting in end face contamination and brittle fracture.

　　(2) Buried plastic drainage pipes should be designed according to the theory of flexible pipes (pipe and soil work together). At the same time, the change in the vertical direction of the pipe in the design state shall not be greater than 5% of the pipe diameter.

　　The inner surface of PPSU PEX fittings should be smooth, and the external waveform should be regular; the inner and outer walls of the pipe should be free of bubbles and visible impurities, and the weld seam should not come off.

　　The section of the pipe after cutting should be trimmed and free of burrs.

　　6, the end face of the heating plate is scratched when taking it out

　　Bumping the end surface during the process of extracting the heating plate will affect the connection strength and may cause leakage.

　　Through the description of the frequent failures of PPSU PEX fittings hot-melt butt joints, it can be seen that the connection surface is very fragile and prone to problems during the welding process. Therefore, in actual operation, we must perform fine welding in the correct way. Good protection of the welding surface can ensure the later use of the pipe.
