ON THE TOPOGRAPHICAL AND PERFORMANCE EFFECTS OF REBLASTING A PREVIOUSLY PREPARED STEEL SUBSTRATE

Product Number: 51218-141-SG

Author: Carl Reed, Kat Coronado

Publication Date: 2018

$20.00

Of recent interest in the coatings world, is what to do when an abrasive blasted substrate does not meet the specified profile. For example, if the blast profile on a steel surface exceeds the specification limit, can the surface be reblasted with smaller abrasive blast media to reduce the profile into meeting the specification? At SSPC 2017 a paper was presented which addressed this scenario and found that the profile can be reduced using such reblasting process.

On the Topographical and Performance Effects of Underblasted and Reblasted Carbon Steel Substrate

Product Number: 51220-278-SG

In this study, the effect on coating corrosion resistance after remediating an under-blasted then remediated to standard preparation is undertaken. In this work, it is proposed to under-blast one set of panels (~1 mil profile), blast to standard one set of panels (~3 mil profile) and remediate to standard a set of under-blasted panels (from ~1 mil profile to ~ 3 mil profile).

Publication Date: 2023

$20.00

Recently, the nickel-based alloy UNS N08827, commercially known as VDM ® Alloy 825 CTP(3), has been presented to the oil and gas industry as an alloy that has been developed to fill in the existing gap between both UNS N08825 and UNS N06625 in terms of localized corrosion resistance. It is a solid-solution nickel alloy with chemical composition similar to UNS N08825, except for its doubled molybdenum content and the no addition of titanium.

Online Asset and Integrity Monitoring to Enhance Safety, Reliability and Profitability

Product Number: MECC23-20244-SG

Author: Ammar Almousa; William Fazackerley

Publication Date: 2023

$20.00

Over the past decades cost pressure in oil refining has increased, especially in Europe where the consumption of oil products is decreasing over time. Refineries are investigating ways to increase margin and, given that they account for around 80% of total refinery expenditure, reduction of crude oil cost is a key factor. One way of doing this is to purchase cheaper and generally less desirable crude from global markets.

On-Line Real Time Electrochemical Corrosion Monitoring in Low Conductivity Fluids – Sulfolane Aromatic Extraction – Part 2

Product Number: 51319-13153-SG

Author: Slawomir Kus

Publication Date: 2019

$20.00

On-line real time corrosion monitoring in processes featuring low conductivity fluids akin to sulfolane aromatic extraction have represented a challenge for traditional electrochemical techniques. Sulfolane specific conductance that is typically about 5mS/cm enables proper determination of corrosion current with standard Linear Polarization Resistance (LPR) technology. Other electrochemical techniques such as Electrochemical Impedance Spectroscopy (EIS) or Zero Resistance Ammetry (ZRA) are useful mostly in laboratory practice but offer little or no utility for field-operational regime. Therefore corrosion processes in sulfolane units are mostly monitored by time-lagging techniques like electrical resistance (ER) and corrosion coupons or by purely qualitative approaches utilizing sulfolane color as the “corrosion indicator”.The authors’ earlier work on multi-electrochemical industrial corrosion monitoring technique integrating impedance measurement Electrochemical Noise (ECN) and Harmonic Distortion Analysis showed demonstrable efficacy in fast and accurate determination of instantaneous corrosion rate in low-conductivity sulfolane solutions. Initial data generated showed that properly adjusted surface area of the electrode facilitates attainment of stable corrosion trends in sulfolane solutions at conductance of about 2-5 mS/cm. Rapid response of the sensor to process changes (temperature oxygen water) in both general and localized modes was also observed.The current paper provides additional data and insights from the authors’ continuing research on sulfolane corrosivity utilizing industrial-type corrosion sensors. Results from comprehensive evaluation of properties of the aqueous phase as well as other relevant process parameters on general and localized corrosion of ferrous metallurgy in sulfolane applications are presented in this paper.

Online Seam Treatment of ERW pipes for proper material selection, process control and toughness improvement

Product Number: MPWT19-14408

Author: C. Cincunegui, M. Coloschi, P. Marino, E. Martínez, and M. Valdez

Publication Date: 2019

$0.00

Electric Resistance Welded (ERW) pipes X60M / X65M API 5L PSL2, with resistance to ductile fracture propagation as per API 5L PSL2 Annex G [1] are achieved not only by setting the proper welding parameters and the steel cleanliness, but also by a combination of metallurgical processes affecting the final weld line and HAZ microstructure. The steel chemistry is the starting point to minimize the presence of inclusions, central segregation and the toughness impairment due to harmful elements, S, P, etc. on the pipe body, with a given casting and rolling technology. During the welding process, the right parameters combination is needed to avoid cold weld, penetrators, and other weld imperfections. At the last stage, the Seam Heat Treatment (SHT) has to be adjusted in a way that the steel response to the thermal cycles leads to the compliance of mechanical requirements at the weld line and Heat Affected Zone (HAZ). This heat treatment is performed through electromagnetic induction using several coils, which allows it to have a rapid and localized heating of the HAZ into the austenitic region, and that is followed by air cooling. The objective is to refine the structure and to eliminate brittle constituents around the weld line. As the SHT strongly affects the weld performance, the optimum processing conditions such as austenitization temperature and cooling rate may not be the same for all steel chemistry, and has to be carefully selected. The capability to model the thermal cycle after the ERW process and the understanding of the metallurgical behavior of different steel chemistries and dimensional configuration becomes the main target of any ERW pipe manufacturer aiming supply reliable Line Pipes as per API 5L PSL2 Annex G. In this work, a numerical thermal model of the SHT is presented along with validation and simulation results. A summary of metallurgical thermal cycle simulations by means of a Gleeble® 3500, applied on different steels is also included.
