When specifying tanks for immersion service that are to be internally lined to control corrosion and prevent product contamination, special design, fabrication details, and surface finishing requirements must be taken into consideration to obtain the desired performance of these linings. As the corrosiveness of the product increases, the design of the vessel becomes more critical, relative to the performance of the lining. This standard is issued to present recommended practices for the design, fabrication, and surface finish of metal tanks and vessels that are to be lined for corrosion resistance and to prevent product contamination.
The standard explains how the suggested practices govern the quality of lining applications. Appendix A depicts both good and bad design practices on tanks, while Appendix B contains a list of suggested responsibilities for the coating applicator to ensure the best protective coating available. Appendix C is a visual and written description of the degree of surface preparation of welds in tanks and vessels prior to lining.
This standard provides requirements for the design, fabrication, and surface finish of tanks to be lined for immersion service. Tanks may be lined for corrosion control or to prevent product contamination. Appendix B lists suggested responsibilities of the purchaser (user), fabricator, and lining applicator regarding design specifications and inspections.
The recommended practices in this standard can also be used in the design, fabrication, and surface finish of tanks or vessels for services other than immersion, such as dry bulk storage of solid materials.
