Abstract:
This invention encompasses a system and a method used in the petrochemical and mechanical engineering area, more specifically in the area of protecting pipes or similarly shaped objects against external or internal damage or wear, which comprises a protective system for the ends and the inside of coated pipes, using the coating itself and other additional devices. The system is comprised of a cup (1), spacer (2), coating (3), external ring (4), and cap (5) used in the production line of the pipe-coating process, using the external coating itself, preventing corrosion and mechanical damage at the ends/bevel, in the sandblasted area of the collar and internal surface, from storage and transport to the location where it will be used, and welding in the field or on the vessel.
