You are purchasing a downloadable pdf of this Standard.
This standard recommended practice specifies procedures to design, install, and inspect thin-film organic linings applied to new carbon steel process vessels to prevent corrosion and other forms of degradation, such as hydrogen-induced cracking, or to prevent product contamination. It is also useful for lining applications in existing process vessels and equipment. There is a recognized need for such a standard in order to achieve long-term durability in such applications. The standard is based on applications of organic linings 500 åm (20 mils)or less. Its concepts can be employed in the application of thicker linings but the specified procedures may be modified or not required. This recommended practice is useful for lining vessels in many industries including, but not limited to, refining, chemical, water-treating, and food. The intended users are owners, contractors, inspectors, applicators, vessel designers, protective coatings specialists, and others concerned with the lining of process vessels.
