Corrosion resistance
Provided that the equipment is used for its intended purpose, its safety is not impaired by corrosion.
Sizing
The 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.
