Should there be a standard pressure test application after the installation of SUITALL PP-R system?
Yes. After installing SUITALL PP-R piping system, it is necessary to go through a pressure test. Unlike metal pipes, SUITALL PP-R, like all other plastic piping systems, has to follow different pressure test procedure owing to their mechanical properties of expansion when subject to pressure, temperature difference and coefficient of expansion. (Test procedure acc. To DIN 1988 PART 2 or BS 6700:1977). For detailed information, Q: Is insulation necessary for hot water applications? A: Normally it is not obligatory for the plumbers; to make the insulation since the thermal conductivity of PP-R piping systems is lower compared to metal piping systems (0.24 W/mK). For further information Contact Us Q: What is the difference between PN 20 and PN 25 pipes due to the application areas? A: Life span of PN 25 is longer than PN 20 pipes under the same temperatures and pressure conditions. Especially for the exposed installations, as the expansion of PN 25 pipes are 1/5 of PN 20 pipes, sagging an
