The Best Testing Method for PPR Pipe Performance
In the appearance of PPR pipe fittings, the color should be basically the same, the inner and outer surfaces should be smooth and flat, without dents, bubbles and other surface defects affecting the performance.
The diameter and wall thickness of PPR fittings should meet the requirements. For its transmittance, it can be measured by flashlight irradiation. Good pipes should be opaque to prevent foreign bodies from occurring in ultraviolet irradiation pipes. For the detection of physical and chemical properties, the manufacturer should provide relevant test reports, including longitudinal retraction rate, impact test of simply supported beam, hydrostatic test, melt mass flow rate test and thermal stability test under hydrostatic condition. In addition, the qualified pipe fittings have the health department inspection report. In addition, the applicability of the system should pass the combined tests of 8760 hours internal pressure and 5000 thermal cycles after the connection.
In addition, the surface of PPR pipe should be smooth and flat, and cracks, bubbles, peeling and obvious impurities, serious shrinkage, uneven color, decomposition and discoloration should not be allowed.
