The topic of our paper consists of a technical performances comparison between heat shrinkable sleeves, cold applied tapes and polymeric backed mesh coatings. The comparison is conducted according to the requirements from the international standards EN12068 & ISO21809-3. The comparison is concluding that Polymeric Backed Mesh coating, a one layer, non-shielding coating system, simple and very fast to apply has similar or better performances compared with the requirements for shrinkable sleeves and cold applied tapes from EN12068 & ISO21809-3. Petrojet from Egypt is one of the most important contractor operating in North Africa and the Middle East. Petrojet conducts its own corrosion protection strategies depending on the equilibrium between all variables including: materials performances, coating conditions, total cost, applicability and the cathodic protection system level. According to Petrojet integrated engineering process, Polymeric Backed Mesh coating system has been recently selected for number of projects (pipeline / piping rehabilitation) and also recommended for future projects as field joint coating.
