Flanged connections require special attention because of the exposure to corrosion. Therefore, a regular maintenance will prevent the destruction of fasteners and flanges themselves that have a positive impact on the durability of the entire pipeline as a whole. Of course, apart from basic requirement of making use of reliable, solidly-crafted stainless steel flanges and tube plates by a decent vendor (e.g. AlexanderComley with facilities located in the United Kingdom), the engineers should keep in mind the natural long-term processes.
Most often, the pipeline begins to break down at the molecular level after welding, but there are ways to ensure the safety flange connections: it can be done using the inhibitors, the use of corrosion-resistant materials, cathodic protection and protective coatings.
