Gents, We are on going to initiate refinery corrosion best practice manual. In regard to that any one had a good item to share with me. Are you having corrosion control practice at your refinery to control the corrosion? Your help will more valuable. After I Finished I will post the manual in weekly basis Mark Corrosion Engineer USA

Mark, I think your idea is great, I recommend to you split the manual by degradation mechanism and the units within refinery where these will acting, like API 571 does. Also you can incorporated the approach of monitoring key process variables that affect mechanical integrity, i.e pH, injection wash water rate, etc. People from Equity Eng. Group has interesting papers related to that issue. If you need some input from my side let me know%A1. Regards Alex

Mark / Luis If RBI(Risk Based Inspection) is implemented / followed in a refinery, automactically an in-built best corrosion practice manual is prepared and implemented. RBI needs a qualfied team of exeprienced professionals in the company ( to analyse from corrosion. material, process, design, protective approach, testing NDT and other means, managment involvement and ystematic montoring and documentation in addition to preparing detailed manuals) to stream line procedures, analysis of failure occurence, implement systematic testing needs, documentation, manual for implemntation and follow up. Trust this is of help to you.
