Pipe Coating/Wrapping Plant

PAXAA provides plants for pipes with different coating solutions in compliance with the most rigorous international standards for water industry projects. PAXAA coating system and line pipe packages can be used on site or factory for demanding applications.

In addition to our own coating plants, we work in alliance with coating manufacturing companies, and therefore we are able to provide a variety of coating systems.
