Based on this information, the requirements for the ARO coating are determined, such as flexibility, impact, compression, gauging, abrasion, and field and application restrictions among others. This information will be used to define the coating selection and installation sequence such as the total dry film thickness requirements, coating installation sequence, field joint coating solution, etc.<\/p>\n<p>Among all these considerations, the selection of the mechanical protective coating is the most critical step in the design of the HDD process.
