This is a recommendation guide. Chromalox cannot warrant any Electric Heat Trace against failure by sheath degradation if such failure
is the result of operating conditions beyond the control of the heater manufacturer. It is the responsibility of the purchaser to make the
ultimate choice of sheath material based on knowledge of the chemical composition of the corrosive solution, character of materials
entering the solution, and controls which maintains the process. |
