The Proper Choice for Transferring Potable Water – Stainless Steel Tube
Stainless steels have been used in the treatment, storage and distribution of drinking water for over thirty years. Today that use is increasing and there are opportunities worldwide for further increase. The benefits to society and to industry are better water quality and reduced environmental impact at lower cost.
The excellent corrosion resistance of stainless steels when they are applied correctly underlies these benefits. There is no general corrosion so there is no need for a corrosion allowance, or any protective coating, or any control of water chemistry (except normal biocide treatment), or any corrosion protection system. Correct grade selection and good practice will minimise the risk of any localised corrosion. Therefore there is practically no contamination of water in contact with stainless steel and equipment will last a long time.
