Through the Laboratory for Corrosion and Protection (LCP), the Institute experienced a breakthrough in studies of the influence of the alternating current interference of cathodically protected pipelines. Together with Cenpes / Petrobras, the Lab recently developed a new methodology and an AC probe to evaluate the probability of corrosion due to alternating current interference. It designed a probe for in-field measurements providing reliable parameters to assess the AC corrosion of cathodically protected pipelines.

IPT has a complete infrastructure both laboratory facilities and specialized technician for pipeline external corrosion.

The following equipment is available for external corrosion studies:

  • ScopeMeter Fluke, mod. 123
