CASE STUDY-Dated Sep 18th,2026

DRILL PIPE INTERNAL COATING PRODUCTION LINE

01 PROJECT OVERVIEW

CoatTech was invited by Proliner Oil , a specialized GRE lining services company in Egypt, to participate in the initial supplier evaluation for a new drill pipe internal coating production line.

The client is establishing a new facility in Egypt for internal coating of oilfield drill pipes, requiring a complete turnkey production line with stripping and recoating capability for used pipes.

CoatTech's previous technical exchanges with the client's team earlier this year provided a solid foundation for the current evaluation. The client has expressed a clear preference to build upon the previous technical concept rather than restart the evaluation from the beginning.
