Gestión de la Integridad

Main tool for the knowledge of the state of the integrity of the pipe. We are specialists in inspection techniques for underground pipelines.


Procainsa combines experience in operation and field inspections as well as data management to ensure safe pipeline operation.

Sistemas de Puesta a Tierra

Placed by star-plates, javelins electrodes, make these earthing systems are highly reliable.


The safest way to date, to protect against the direct impact of lightning, is its capture, derivation and dissipation to earth.


All our courses have as a principle “Learning by doing”, having a high practical component in the client’s facilities.
