In the oil and gas industry, solid particle erosion is a common challenge in pipelines, flowlines, and fitting components such as elbows. Elbows have been widely used to change the flow direction in industrial flowlines. When erosion occurs due to the impact of solid particles, it leads to significant financial and environmental threats.

Elbows in series are commonly encountered in various piping systems on oil and gas subsea platforms. In numerous oil and gas fields, solid particles are entrained with produced fluid causing solid particle erosion of these elbows. Therefore, solid particle erosion was examined in two standard ID 3-inch (76.2 mm) elbows in series. The distance between the two elbows is twice the pipe diameter (2D). Firstly, paint removal studies were performed to identify the location of the maximum erosion in the second elbow with superficial gas (air) and liquid (water) velocities of 31 m/s and 0.1 m/s, respectively, using 300 and 75 μm particle sizes. Secondly, erosion measurements were conducted in two standard stainless-steel (SS316) elbows with 25, 75, and 300 μm particle sizes. The results of the erosion measurement in the annular flow condition were compared with the gas-solid flow with a gas velocity of 31 m/s and particle sizes of 300 and 75 μm. The paint removal experimental studies showed that the location of the maximum erosion changes with changing the particle sizes in the second elbow. The erosion measurements showed that the erosion ratio (2nd elbow/1st elbow) in gas-solid is higher than in annular flow conditions by a factor of 14.25 and 5.8 with 75 and 300 μm particle sizes, respectively. Also, Computational Fluid Dynamics (CFD) simulations were performed for gas-sand flow conditions with 31 m/s gas velocity to study the effect of particle size on erosion in the investigated elbows. The CFD results over-predicted the erosion ratio (2nd elbow/1st elbow) by a factor of around 2.1 and 2.4 for 75 and 300 μm particle sizes, respectively.

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.

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.
