Oxidation of swimmingpool lamps

It has been shown that steel corrosion can be influenced by 3 factors:

1. Presence of chlorides
2. Temperature increase
3. Low PH values

Salted implants use electrolytic cells to produce chlorine, starting from sodium chloride (salt), present in the pools in variable concentration betweem 3-6 g/l. It has been demonstrated that chlorine concentration higher than 500 ppm (higher then 0,5 g/l) may cause oxidation phenomena of steel. This means that anything made of steel (lamps, stairs, grilles, nozzles, etc), subject to these conditions, may be affected by oxidation over time. Where the surface protective layer of steel is more torn apart, it could create a real holes or lacerations over time (this phenomenon is called "pitting").

In order to avoid these kinf od problems we suggest to verify that products are made with fine steel (line naval steel AISI 316L), that there are protective materials on the surface (teflon, professionbal chemical products, etc), there aren't working processes (bending, punching, welding, etc. ) that can have contaminated the steel creating critical points which can be attacked by the "pittint" phenomenon.

To preserve them we suggest to keep the parameters of chlorine concentration, temperature, PH constantly monitored, use low concentration of salt and periodically check the externall appearance of steel. In case of oxidation principles, proceed to remove the product through suitable chemical or electrochemical processes. the more you can ensure the reflective effect in the steel, and the more the steel will be resistant to corriosion phenomena.

If you lamps has holes or laceration you just have to change it and substitute with a new one.
