The range of factors affecting the susceptibility of equipment to corrosion under insulation (CUI)
are numerous. Some of these factors might be controlled through better design, more robust
installation procedures, and using better quality coatings. However, there are other risk factors such as operating temperature, material type, and environmental conditions that cannot be easily modified.

Reducing Embodied Carbon by Using Fibre Reinforced Polymers (FRP) Rather than Steel

Climate change and global warming due to human-generated greenhouse gases are potentially the most prominent issues facing the political and economic world in recent times. “Human activities are estimated to have caused approximately 1.0°C of global warming above pre-industrial levels, with a likely range of 0.8°C to 1.2°C. Global warming is likely to reach 1.5°C between 2030 and 2052 if it continues to increase at the current rate.”

Reduction Of Conservatism In SSC Testing For Sour Gas Well Tubulars

Martensitic stainless steel (MSS) well tubulars are favorable due to their high strength and relatively low cost and are therefore widely applied in the Oil & Gas industry. This is especially the case for 13Cr and Super13Cr grades, which are often selected for mildly sour gas fields, where a relatively low content of H₂S is present. When selecting martensitic stainless steels for sour service, the susceptibility to Stress Corrosion Cracking (SCC) and Sulfide Stress Cracking (SSC), determined by standard laboratory tests, are the most important selection criteria.

Reduction of Tool Wear and Loads During Friction Stir Welding of Steel for Pipeline Fabrication

Product Number: MPWT19-14275

Author: Grégory Toguyeni, Ozan Caliskanoglu, Christian Pfeiffer

Publication Date: 2019

$0.00

Friction stir welding procedure development was initiated on steel grades S460 G2+M and S690QL1 in plate wall thicknesses of 10 and 15mm. In order to tackle the challenges of the high mechanical loads on the tool as well as its premature wear, a combination of preheating and optimized weld backing set-up was implemented. The inductive preheating allowed a 28% reduction in welding torque and a significant reduction of the tool wear, particularly during the critical initial plunge of the tool within the base material. A comparison of Mo-based and W-based tool was performed, allowing identifying the W-based tool as having a better combination of high temperature strength and wear resistance. Different backing arrangements and materials were investigated. Ceramic backing inlays were used in order to reduce the heat loss at the root area and maintain an acceptable stirring of this zone to achieve full penetration welds. The welds quality was assessed via metallurgical examination, bend tests, and confirmed the possibility to perform sound full-penetration, one-sided welds. The contribution of the preheating to the process as well as the quality and mechanical properties of the welds will be discussed here.

Re-Evaluating Electrochemical Impedance Spectroscopy (EIS) for the Field Inspector’s Toolbox: A First Approach

Product Number: 41214-837-SG

Author: Bobbi Jo Merten, Allen Skaja, David Tordonato, Daryl Little

Publication Date: 2014

$20.00

Electrochemical Impedance Spectroscopy (EIS) has maintained a presence in protective coatings laboratories for decades. EIS is valuable in that it captures resistive and capacitive changes to a coating film as it is exposed to the environmental conditions that produce these changes, i.e., degradations. It also assists in ranking coating systems for their anticipated corrosion protection performance, complementing qualitative, visual observations.

Refinement Of Citric Acid Passivation Methods And Comparison To Traditional Nitric Acid Based Chemistries

Product Number: 51322-17628-SG

Author: David G. Enos, Derek Wichhart

Publication Date: 2022

$20.00

Traditional solutions for the chemical passivation of stainless steel are nitric acid based, with the addition of sodium dichromate as an inhibitor for precipitation hardened and free machining stainless steels. These passivation chemistries are difficult to handle from an environmental health and safety point of view, particularly the dichromate inhibited versions. Citric acid passivation has been pursued as a replacement for both nitric acid and inhibited nitric acid based chemistries for many years, and has been incorporated into consensus specifications such as ASTM A967 and SAE AMS2700.

Refinement of Pitting Factor Basis to Evaluate Minimum Nitrite Requirement in Dilute Waste Chemistries

Product Number: 51324-20801-SG

Considering that chloride concentrations are an order of magnitude lower at SRS than the maximum chloride previously tested to evaluate pitting susceptibility of carbon steel, it has been proposed that the Pitting Factor methodology be refined to determine if a reduction in the minimum nitrite requirement is warranted in more dilute solutions and those with chloride concentrations more indicative of waste tank chemistries at SRS. Through the use of cyclic potentiodynamic polarization, the susceptibility of A537 carbon steel to pitting corrosion was evaluated. The Pitting Factor was shown to accurately predict pitting susceptibility throughout the chemistry envelope evaluated. In addition, it was shown that nitrite is not required for inhibition of pitting corrosion in tank conditions with chloride concentrations observed at SRS and up to 4 M nitrate. Based upon these findings, new control limits were proposed that removed the minimum nitrite requirement within the chemistry envelope evaluated up to 50 °C.
