In Oil & Gas facilities projects, coating system selection of bulk valves is challenging for EPC contractor to manage because their quantity is extensive and they are installed at each specific situation. IMM (Inert Multi Polymeric Matrix) / IC (Inorganic Copolymer) coatings, hereinafter referred to as IMM, which can be applied under various situations are anticipated to be applied for the bulk valves. Several types of IMM paints have been introduced to the market and corrosion protection performance were evaluated in this paper. Test panels of IMM coatings were prepared from five different manufacture’s brands, with variations in dry film thickness, hereinafter referred as DFT, (125µm/250µm) and with or without heat curing. Corrosion protection performance was tested by salt spray tests (720 hours, 1440 hours) and natural weathering tests (18 month), and evaluated by degree of rust, pull-off tests, and EIS (Electrochemical Impedance Spectroscopy) tests. The results of salt spray tests and natural weathering tests varied depending on each brand's product. The overall trend indicates that panels with a 250µm DFT and without heat curing panels demonstrates better corrosion protection performance rather than panels with a 125µm DFT and with heat curing. In the EIS test, some test panels showed a significant drop in impedance values at low frequency (0.1Hz) with heat curing, which may suggest a degradation in corrosion protection performance. In conclusion, it is recommended to use IMM coatings with a 250µm DFT and to be cautious when applying them at high temperature services.

Evaluation On Applicability Of Nickel-Base Alloy Weld Materials With High Chromium Content In BWR Environment

Product Number: ED22-17130-SG

Ni-base alloy weld material has been widely used for primary reactor components of BWR. Stress corrosion cracking (SCC) in Ni-base alloy welds is of an increased importance and an ongoing subject in the industry to secure material reliability of the components especially for long-term operation of light water reactors. Although alloy 82 has shown excellent service performance in BWR applications, it is known that alloy 82 exhibit SCC susceptibility in laboratory tests under simulated BWR environment with a combination of particular, severe test conditions such as high level of material cold work and highly accelerated environment. In addition, few experiences with SCCs in the welds associated with alloy 82 have been recently reported in the operating BWR plants.

Over the last few years, the protective coatings industry has seen an increased demand for high performance waterborne coatings in the field of corrosion protection. Market drivers such as “Sustainability”, “Greenability”, and ongoing regulatory and environmental concerns continue to force coatings producers to look for other viable options to replace conventional solvent borne technologies.

Evolution of Microstructures, Mechanical Properties, and Stress Corrosion Cracking Resistance of Alloy 718 Manufactured by LPBF and WAAM

Laser powder bed fusion (LPBF) is becoming a popular additive manufacturing (AM) process for oilfield components of Alloy 718. Despite attracting features, AM 718 is often uneconomical, greatly limited in size, while the build properties differ from wrought counterparts. Among AM processes, wire arc additive manufacturing (WAAM) offers a cost appeal and an improved scalability for Alloy 718. In this investigation, Alloy 718 coupons built by both LPBF and WAAM are compared for their microstructures, mechanical properties, and sulfide-stress cracking (SSC) resistance. To approach the properties of the wrought alloys, post-processes such as stress relief, hot-isostatic pressing, solution annealing and age hardening are revisited by jointly analyzing microstructures and mechanical properties. Further, slow-strain rate tests were completed to assess the SSC susceptibility of WAAM 718 relative to LPBF 718. This investigation demonstrates that LPBF 718 is capable of properties in line with its wrought counterpart, whereas much more work is needed for WAAM 718 to reach satisfactory quality and consistency.

Evolving Excavation Damage Modelling Predictions to a Data-Driven Approach

Excavation damage is a recognized threat to pipeline integrity when external human activity contacts the pipe body creating a change in shape (i.e., dent, ovality) or wall thickness (i.e., gouge). Industry standards provide similar, but slightly different variations on this definition:

• ASME2 B31.8S (1) Section A-8: “Third party damage is defined in this context as third-party inflicted damage with immediate failure, vandalism, and previously damage pipe.”

• API3 RP 1160 (2) Annex A.9: “This threat arises from excavation, drilling, boring, farming, or other soil moving or removal activities where the mechanical equipment being used comes in contact with a buried pipeline causing it to leak or rupture.”

• CSA4 Z662:19 (3) Annex H: “Third party: Inadvertent external interference by a person or group of people other than the operating company and its employees and contractors.”

Nuclear energy currently contributes approximately 10 % of the worldwide energy mix.¹ Nuclear energy generation is a form of low-carbon electricity, typically run as base-load, which alongside renewables can help nations toward climate change goals. Nuclear fission thermal reactors make up the majority of the reactors operating today. Nuclear fusion on the other hand is a promising alternative which produces less radioactive waste and does not have a reliance on the finite source of uranium fuel. Eurofer-97, a reduced activation ferritic-martensitic (RAFM) steel, will be used as a structural material for fusion reactors. The earliest literature reference to RAFM steels originated from 1994 by Abe et al.² One option for the European demonstration fusion reactor (DEMO) is to use a water-cooled lead-lithium (PbLi) breeder blanket (WCLL BB) design for heat extraction. Breeder blankets will be used to generate a source of tritium, for the fusion reaction with deuterium.

To reduce maintenance costs while maintaining safety, different corrosion mitigation strategies have been utilized. In addition to new structural materials and advanced protective coatings, improved maintenance planning approaches, including Condition Based Maintenance (CBM) approaches, have seen growing use over the past decade. One goal of any Condition Based Maintenance (CBM) effort is to use all available on-aircraft data as well as field and depot-based maintenance information to align resources in a timely manner to ensure aircraft safety while reducing maintenance and repair costs.

Examination Of Corrosion Sensor Data From Long-Term Field Exposures

The current approach to corrosion severity prediction is to use long-term averages of environmental parameters (such as relative humidity, temperature, and pollutants), geographic features (such as coastal proximity), and witness coupon corrosion rates of indicator materials to classify an environment into one of a small number of severity categories. However, recent work has revealed that brief changes in environmental conditions—even those lasting only a few hours—can significantly affect total corrosion damage, and long-term averages of environmental conditions are not sufficient to accurately predict cumulative corrosion damage. To more accurately measure the corrosion damage from these short-term events, corrosion sensors are becoming increasingly popular. The frequent acquisition of data and increased measurement sensitivity are attractive features, however the data from these corrosion sensors is still difficult to interpret in many cases.
