Implementation of Pulsed Laser Ablation Technology in Surface Preparation Processes

Product Number: 51324-20982-SG

Author: Matt Binsfield

Publication Date: 2024

The transition of pulsed laser ablation (PLA) technology into the hands of maintainers within shipyards and the transportation industry requires an assessment of multiple factors. From the technical perspective relative to surface preparation and corrosion mitigation, it is essential to understand the impact of PLA energy into substrates and the resultant adhesion characteristics of subsequent coatings. Technical areas to be discussed include metallurgical properties, such as stress corrosion cracking, weldability, bulk properties, fatigue life, as well as adhesion. The effective application of laser ablation is of critical concern to preservation professionals, which requires an understanding of how the process works, the proper appearance of a laser ablated surface, whether that is a tightly adhered existing coating prepared for re-coating, or to expose some or all of the base metal substrate. Accordingly, both laser operators and inspectors need specific information and training to appropriately use the technology to meet preservation objectives and requirements. These needs will be addressed through a forthcoming AMPP Laser Ablation Standard, Technical Guide, and Visual Guide. Determining where to apply PLA based on extensive test data currently available, as well as understanding where future investigation is required, will be summarized.

To properly understand the necessary steps in implementing corrosion modeling into existing CFD software, it is necessary to verify the accuracy of the corrosion predictions made by the software. To do this, simulations are created that replicate experimental work performed in well understood geometries. The corrosion models are implemented in these simulations, and the resulting corrosion rates, as well as hydrodynamic and mass transfer characterizations, are compared to results from the experimental work. Presented herein is work investigating corrosion phenomena in a thin channel flow cell apparatus, as well as single phase straight pipe flow. In both geometries hydrodynamics, mass transfer, and electrochemistry have been simulated at a variety of conditions; the accuracy of the results were confirmed through comparison with experimental data and well tested correlations. Both geometries showed a high degree of agreement between the simulations and the experimental work, indicating that the methodology is viable to be used in other geometries.

Fracture surface morphology is useful in determining the mechanisms involved in cracking. Features in the fracture surface of steel like micro-void coalescence or dimples are often related to ductile crack mode, while features like cleavage, and rock-candy showing grain boundary cracking are commonly related to brittle crack mode. Some fracture surface may have a predominant feature, while others may have presence of mixed features. Types of stress corrosion cracking (SCC) are commonly identified by the features present in the fracture surface. Features showing transgranular quasi-cleavage cracking are often related to near-neutral pH SCC, while features that show rock-candy intergranular cracking are often related to high-pH SCC [1].

Canadian Oil Sands mining operations have been producing oil from sand ore from the early 1960s. Oil Sands mainly consists of high hardness quartz, silica, bitumen and water. Bitumen production processes include mining the sand, washing it with hot water, slurry transportation, tailing disposal and bitumen production. Abrasion, gouging wear, impact wear, erosion and erosion-corrosion are predominant degradation mechanisms in Oil Sand mining operations.

Important Factors in Pipe Butt Welding of Super Duplex Stainless Steel (SDSS) UNS S32760 Using the GTAW Welding Process

Product Number: MPWT19-14287

Author: Dr. Glenn Byrne

Publication Date: 2019

$0.00

The paper considers best practice to realise the optimum combination of strength, toughness,
corrosion resistance and radiographic integrity in UNS S32760 pipe girth welds made using the
GTAW process.
Aspects of fit up, tacking, root gap are considered. The effect of weld heat input and heat input
control through the thickness of the joint, welding technique, inter pass temperature control and
the use of different combinations of shielding and backing gasses on corrosion resistance of
joints is presented. Current specification, procedure and welder qualification requirements are
discussed, as is the need for supplementary testing, in particular quantitative microstructural
evaluation.

Biocides play a critical role in the oil and gas industry as they are used as chemical additives during drilling, completions, and water-flooding operations. Their primary purpose is to prevent various problems such as the formation of biogenic H2S, microbiologically influenced corrosion (MIC), and reservoir plugging caused by microbial growth. With advancements in horizontal drilling and well completion technologies, the economic exploration of unconventional energy resources has become possible alongside traditional drilling methods.

In Upstream, CRAs (Corrosion Resistant Alloys) are widely selected to handle seawater and brines in piping, valves, pumps, heat exchangers, vessels, and seawater injection^1-4. Also, disposal of produced water is commonly performed through injection into spent fields. Water from a variety of sources including produced water, seawater and surface/fresh water may also be injected to create pressure drive for existing fields. Usually dissolved oxygen (DO) is not fully controlled when there are multiple sources of injection water and sometimes even possibility of injection of fully oxygenated water exists. For oxygenated seawater, the PREN (Pitting Resistance Equivalent Number = %Cr + 3.3 *(%Mo + 0.5 %W) + 16 %N) shall be >40 and limits are applied to the temperature4. Other applications involve Solid CRA or cladded production pipelines which may get flooded with seawater during installation and precommissioning.
