In realizing the importance of applying efficient anti-corrosive measures that can lengthen the life of the pipe, Tenaris offers a tailor-made anode pad installation service.

This service involves installing anode pads prior to applying protective coating systems to line pipes which produces a better quality final product and reduces installation time of the anode itself.

Installing Anodes without Anode Pads

Corrosion, abrasion, and other forms of wear reduce the thickness of pipeline walls, which leads to pipeline failure.

To assist in the protection against corrosion, protective coatings are applied to the pipes, along with anodes, which are cathodic protective accessories fitted at specific intervals on the pipeline.

Anodes are usually installed after the pipe has been coated, however attaching the anodes at this stage increases the risk of damaging the pipe because the coating has to be removed in order to install the anode, which ultimately increases time at the installation phase.

In response to our customers’ request to decrease time at the installation phase, Tenaris developed the anode pads solution. Overall, this process improvement ultimately reduces cost, increases production efficiency, and effectiveness of the cathodic protection and protective coating systems.

With this solution, the anode pads are created from a mother pipe that is certified with the same mechanical properties and steel grades (i.e. X52, X65) as used in the line pipe. The mother pipe can also be manufactured to
have a specific anode pad steel grade, such as SA275JO.

It is important to note that Tenaris installs the anode pads on uncoated pipe. After the anode pads have been attached to the pipe using the Shield Metal Arc Welding Process, the protective coating is applied.

At this stage, the Tenaris Project Manager works with the client to guarantee on-time delivery of the coated line pipe with anode pads already attached, according to the client’s specification.
