Measurements

Cathodic protection is an important step towards high-quality metal products, but it only makes sense if its operation is regularly monitored. That is why Merrem & la Porte has its own team of experts who can perform all necessary inspections, certifications, and tests.

The cathodic protection department of Merrem & la Porte B.V. has its own measurement service. Using advanced equipment, our skilled employees conduct potential measurements.

Cathodic protection measurements:

• Control measurements

The cathodic protection department of Merrem & la Porte B.V. designs and supplies complete CP systems with sacrificial anodes for underground storage tanks and small underground steel pipelines (such as sinkers). Additionally, we design and deliver cathodic protection for large pipeline networks of steel gas pipelines or transportation pipelines in the chemical industry.
