Corrosion resistance

When used for its intended purpose the safe functioning of the electrode will not be impaired by  

corrosion.

Sizing

The electrode body must not be subjected to sharp increases in pressure. Welds and flanges of the 

electrode are designed to withstand dynamic loading (bending and alternating stress). The dimensional 

allowances for corrosion reflect the latest state of technology.
