Corrosion problems in industrial pipelines
Thread Content
The transportation pipelines for the purification of carbon dioxide gas containing water vapor can be perfectly addressed using 304 stainless steel. But the owner felt that the installation had no economic value and insisted on using carbon steel pipes. Carbon steel pipes are not suitable for use in carbon dioxide gas containing water vapor due to rapid corrosion; therefore, cathodic protection of these pipes is considered as a way to slow down corrosion. Are there any such cases in companies?
For the problem of corrosion in industrial pipelines, a relatively economical solution is to use cathodic protection. This method has been widely applied in many industries, including oil and gas pipelines, ships, ports, and so on. In an environment of carbon dioxide gas containing water vapor, cathodic protection can also effectively delay the corrosion of carbon steel pipelines. In practical applications, it is necessary to determine appropriate protection potentials and current densities based on specific environmental conditions and material properties, in order to achieve the best anti-corrosion effect. .
