Corrosion and Protection of Chemical Equipment in Coking Plants
Thread Content
Our company is a coal coking enterprise; our facilities have been in operation for over a decade. At present, the equipment is severely corroded and aged, with frequent leaks occurring especially in the gas pipelines, ammonia pipelines, and circulating water pipelines in the chemical production workshop. We would like to seek advice from experts regarding the causes of corrosion and effective measures for prevention and improvement!

One can refer to relevant literature and similar usage conditions, then analyze the specific situation on a case-by-case basis to gradually develop a remediation plan.
Wang Wei is right; it’s necessary to analyze each situation on its own
What needed to be replaced has been replaced, and what needed to be repaired has been repaired
For pipeline replacement of ammonia solution, contact me – steel-reinforced polyethylene plastic composite pipes
The main causes of corrosion in gas pipelines are hydrogen sulfide; ammonia is alkaline, and there is also circulating water. Under these three conditions, polyaniline coatings can normally withstand the corrosion, so their use is recommended.
