Metal loss due to corrosion is a universal phenomenon in refineries which could in turn cause leakage or explosion if not well monitored. There are several units in a refinery such as crude distillation unit, hydro-processing unit, acid alkylation unit, etc. In each unit, there are hundreds of pressure vessels which have different potential damage mechanisms. Hence, it’s critical to establish an effective and efficient way to monitor thickness changing behavior.

In API 510, it offers two ways for corrosion rate determination, one is using” point-to-point” method, in
which long-term and short-term corrosion rates can be compared so that the corrosion rate which best reflects the current process can be chosen.
The other way is “statistical analysis method”, in which owner can establish a representative and suitable model to monitor and analyze pressure vessel corrosiveness behavior in order to maintain its mechanical integrity. This paper, based on the experience of thousands of pressure vessels, will
present the model using linear regression which has been used successfully to monitor corrosion rate. And to maintain the quality of thickness measurements, statistical approaches like control chart have been applied effectively to reduce inspection errors.

The goal of the Paris Agreement is to limit global warming to below 2°C, preferably 1.5°C, compared to pre-industrial levels.1 While the world is slowly transitioning to more sustainable energy sources to reach this target, one of the ways to reduce the CO2 in the atmosphere is to capture it and store it in depleted gas fields. According to the IOGP1, the total number of CCS projects in Europe is 65 in 2022.2 The aim of these projects is to store around 60 MtCO₂/yr by 2030.

Bulk items such as cast and forged valves are installed under various temperature conditions. It is exposed to a wide range of temperatures, therefore the coating product applied to bulk items should have appropriate heat resistance performance. However, it is very difficult to select a suitable coating system since the temperature condition is not determined in the valve manufacturing stage. For this reason, unsuitable coating systems are often applied, causing coating defects in the field operation. Therefore, it is necessary to apply a coating system that can cover a wide temperature range to prevent this problem.

As far as the automotive sector is concerned, braking discs (BDs) are objects usually made of Grey Cast-Iron (GCI), i.e. a material exhibiting overall good mechanical properties and castability, but poor corrosion resistance. In particular, looking at the standard working conditions of a disc brake system, several environmental factors can cause and enhance GCI corrosion phenomena, such as: i) atmospheric moisture; i) ionic species contained in aerosols (e.g., chlorides and sulfates); iii) air differential corrosion caused by discs surface soiling by mud or other materials; and iv) galvanic coupling between the rotor and the braking pads.
