Is ABS suitable for conveyance of water (RO Water) treated by RO process (Reverse Osmosis)?
Durapipe ABS is used extensively for applications involving high purity water (de-ionised, de-mineralised water), examples of some of the existing UK users being Glaxo Pharmaceuticals, National Semi conductors, Permutit and Technicolour Limited. A typical pure water system for producing rinse water for Semiconductor manufacture has a quoted resistivity of 18.24 Meg ohm cm, (0.055 micro siemens/cm conductivity), with the water being “less pure” if the resistivity number is lower, or the conductivity is higher. The materials used by Durapipe in the manufacture of both the inch and metric ABS pipework systems do not contain plasticisers or stabilisers such as those that are present in materials like PVC-U, which can be leached out into the water. Solvent cements are used in the construction of the joints, and on completion of the installation, care must be taken to ensure that all traces of the solvent fumes have been purged from the system. The exact time required to purge the system wil
