- Aluminium bracelet anodes
- Sled-mounted anodes
External coating is the primary system for corrosion control on submarine pipelines.
A cathodic protection system based on sacrificial anodes is also applied to protect the pipelines in case of any deficiency in the coating system.
Bracelet-type sacrificial anodes (aluminium-indium as a standard, or sometimes zinc) are the usual preferred system, although in cases of high temperatures; sled type anodes are typically installed. Tecnoseal Industry s.r.l. confronts the challenges of this extremely harsh saltwater environment by careful selection of materials and a constant commitment to research and innovation.
