Case Study - AC Mitigation Design for Multiple Pipelines without Powerline Data

Product Number: 51324-20632-SG

Author: Baotong Lu; Hui Yu

Publication Date: 2024

$40.00

This case study demonstrates the applicability of the AC Interference Mitigation (ACIM) design method (reported in our preceding paper, C2023-18983) under the conditions of unavailable power data for collocated powerlines and for multiple pipelines that are electrically connected. It was assumed that field AC voltage readings were collected from test stations along at least one pipeline. The procedure is as follows: 1. Estimate the power loads of the powerlines using a trial-and-error method via simulating the AC voltage profile(s) of the pipeline. 2. Validate the predictive model that is based on the estimated current loads with AC voltage readings of the other pipelines, if applicable. 3. Execute ACIM design when necessary. 4. Validate effectiveness of the recommended ACIM action via new field AC readings collected from test stations along the pipelines after the ACIM is applied.

Improvements to the Replica Tape Test Method (ASTM D4417C / NACE SP287 / ISO 8503-5)

Product Number: 51324-21157-SG

Author: Michael Beamish

Publication Date: 2024

$40.00

The Replica Tape method is a trusted method used by inspectors worldwide for decades to measure surface profile height. Previous studies have shown the method to be highly precise and accurate, but an intricate burnishing technique and requirement to average two different grades of replica tape in some measurement ranges made the method challenging for some users. This paper details two proposed changes to the method: an updated burnishing tool and linearized measurement scale to eliminate the need for averaging. A study was conducted to determine the accuracy and precision of this updated method, involving measurements performed by 15 users of varied experience on a range of test panels blasted with varying of media and profile heights.

Effects of Minor Alloying Elements on the Metal-Dusting Behavior of Ni-Based Alloys

Product Number: 51320-14657-SG

Author: Bingtao Li, Wei-Ting Chen, Brian Gleeson, Heike Hattendorf

Publication Date: 2020

Alloys are often found to suffer much greater metal-dusting attack under high-pressure conditions compared to ambient-pressure conditions. Ultimately, the resistance of a given alloy to metal dusting depends on the formation of an oxide scale that is impermeable to carbon which, in turn, depends on scale composition and structure. This paper reports the metal-dusting behavior of several Ni-based alloys having relatively high Cr contents (about 30 wt.%) and different controlled minor levels of Fe, Al, and/or Si. Testing was conducted under 20 bar total pressure of a high-carbon-activity gas at 600 °C (1112 °F). The exposed alloys were analyzed by SEM and TEM techniques to evaluate the oxide scales and evidence of carbon ingress. It was found that aluminum is beneficial to improve metal dusting resistance by reacting to form a continuous inner layer of alumina; whereas iron is detrimental to resistance. Mechanistic aspects of the role(s) played by minor elements in affecting metal-dusting resistance are considered.

Influence of Structural Features of Scale Inhibitors on the Control of Silica Scaling

Product Number: 51319-12861-SG

Author: Kostas Demadis

Publication Date: 2019

$20.00

Feedwaters for industrial cooling water systems contain a variety of metal cations (such as calcium magnesium barium etc.) and anions (such as carbonate sulfate phosphate etc.) which overall constitute scaling ions. Their combination (depending on the particular water chemistry and solubility products) creates precipitates and deposits. These mineral salts cause enormous operational problems upon their deposition onto critical equipment surfaces (eg. membranes heat exchanger tubing tower fill etc.). Calcium carbonate and calcium phosphates are the most frequently encountered deposits. Other deposits although less common are equally troublesome. These include amorphous (colloidal) silica. Prevention of scale formation is greatly preferred by industrial water users to the more costly laborious (and potentially hazardous) chemical and mechanical cleaning (for example HF is required for the dissolution of silica deposits) of the adhered scale after a scaling event.This paper focuses on amorphous/colloidal silica fouling and its control by additive-driven inhibition. The use of several designed treatment additives will be described with emphasis on the structural elements of inhibitors used. These efforts address the question “what are the chemical moieties that contribute to silica inhibition and why”? Almost all silica inhibitors are polymers (either charged or uncharged). Certain silica scale inhibitors described can maintain up to ~ 400 ppm soluble silica in solution. Attention will also be paid to the designed chemical approaches that should be used to combat silica scale for example the use of inhibitor blends in search for potential synergistic effects. A detailed analysis will be given on the entire chemical treatment process starting from proper selection of the treatment program to proper application to effective monitoring and maintenance of system performance. Finally the general scope of silica chemistry fundamentals will be presented.

Understanding Sour Service Performance of Coiled Tubing

Product Number: MPWT19-14407

Author: Bruce Reichert, Claudio Morales, Martin Valdez

Publication Date: 2019

$0.00

Coiled tubing is a long (sometimes more than 25000 feet) electrical resistance welded pipes that is uncoiled for the deployment of oil and gas wells to perform a variety of jobs that involve subjecting the pipe to high pressure, axial loads, and contact with acidification, and production environments among others. Since the pipe is coiled and deployed multiple times for different jobs during its lifespan, it is typically plastically deformed and fatigued.
This paper discusses the challenges of improving the performance of this welded pipe base material, as well as its multiple welds, when facing an inhibition failure that could cause exposure to corrosive and/or embrittlement environments.
The product development process resulted in the complete modification of steel chemistry, its welding procedures and heat treatment process. The testing program includes, among other tests, the exposure of the pipe to different environments, followed by fatigue testing to determine the remaining material resistance after such exposure.

Publication Date: 2019

Boiler system is one of the most critical systems for a utility plant. A utility plant had experienced high percentages of boiler downtime owing to boiler tube sheet cracking failures. Investigations carried out revealed high stress at the tube-to-tube sheet joint in the boiler fire-side entrance. Tube-to-tube sheet joints at the boiler fire-side entrance had been fabricated by strength welding and without any expansion. The strength welded joint had created undue stress leading to cracking of the weld joint by thermal expansion. A higher quality expanded joint consisting of expanding, flaring and seal welding the fire-side entrance was implemented during the re-tube process. The utility plant has now zero downtime due to boiler tube failure. This article summarizes the description and history of failures with the boiler at the utility plant; investigations and corrective actions carried out; and the present improved condition of the boilers.

Linear anomalies were discovered during construction activities near to the DC-ERW long seam weld of a 20-inch natural gas pipeline. Magnetic particle testing and phased array ultrasonic testing were applied to characterize the anomalies. Pipe samples were removed from the pipe for additional destructive laboratory analysis. Laboratory analysis included visual assessment, X-ray computed tomography, cryo-fracture, cross-sectioning, metallographic analysis, and scanning electron microscopy. Inspection and testing results indicated that the anomalies were consistent with roller contact marks introduced during pipe manufacturing and did not show evidence of time-dependent growth. Representative anomalies were evaluated using a Failure Assessment Diagram to provide an additional level of assurance. All flaws were found to be acceptable in accordance with general application of API 579 Part 9, Level 2.

Static pressure equipment mechanical integrity (MI) is most typically associated with OSHA Process Safety Management (PSM) as regulated under the Department of Labor. Facilities regulated under the Department of Transportation (DOT) including applicable natural gas and liquefied natural gas are not subject to PSM regulations including the implementation of MI management programs. Nevertheless, MI methodologies such as those prescribed in API 510 and 570 offer a suitable framework for integrity management of DOT-regulated pipeline natural gas facilities such as compressor stations, metering and regulation station, LNG Facilities. These MI methodologies can be implemented to provide appropriate engineering solutions considering typical facilities characteristics including materials of construction, operating processes, and integrity threats and satisfy current DOT integrity management regulation.

Sour Service Qualification of Carbon Steels (SMYS 450 MPa) and Their Welds Considering Field H2S Fugacity / Dissolved H2S Concentration - Qualification at Design and Atmospheric Pressure

Product Number: 51324-20609-SG

Author: Jiangnan (Hugh) Zhang; Ramesh Rao; Felipe Ramirez; Adam Darwin

Publication Date: 2024

$40.00

A Sulfide Stress Cracking (SSC) qualification program was conducted for carbon steel components (piping, flanges, and fittings with SMYS 450 MPa) and its welds for an offshore facility piping system that may carry off-spec gas in the event of a temporary malfunction of the dehydration and H2S removal units. The off-spec sour gas may contain 22% mol CO2 (pCO2 73 bara) and 6,700 ppm H2S (pH2S 2.22 bara) at a total pressure of 332 bara and temperature of 24 °C with condensed water pH of 3.2. The SSC qualification program included two parts. Part I involved testing at 332 bara using batch-loaded high-pressure autoclaves based on H2S fugacity (fH2S) as permitted by NACE MR175/ISO 15156-2. Part II involved testing at atmospheric pressure by matching the predicted dissolved H2S concentration of the aqueous phase (cH2S) and by matching the predicted fH2S of the gas. Part I and Part II tests were conducted using the same set-up (NACE TM0177 Method A tensile) and stress (75% AYS). Hardness readings taken at the base material (BM), heat affected zone (HAZ) and weld metal (WM) were below 250 HV10 near the root and mid-section of the rings (with couple of single reading exceptions along the HAZ for the rings involving flanges and fittings). Hence, most of the tested carbon steel rings could have been considered suitable for sour service through compliance with NACE MR0175 /ISO 15156-2. Nevertheless, post-examination of test specimens revealed susceptibility to SSC in both Part I and Part II tests. These lab results suggest that NACE MR0175 /ISO 15156-2 guidance on carbon steel SSC resistance, which is based on hardness, is not always conservative.

Unveiling the Mechanical Feasibility of Glass Reinforced Plastic for Post Combustion CO2 Capture Amine Service: A Thorough Examination

Product Number: 51324-20710-SG

Mitigating global warming and reducing CO2 emissions from the environment necessitates the implementation of carbon capture, sequestration, and storage (CCS) as an immediate and feasible solution. Amines are widely employed to capture CO2 gas from industrial exhaust streams. To enhance the cost-effectiveness of amine services, the incorporation of glass-reinforced plastic material holds immense potential for substantial cost benefits. The primary aim of this study is to assess the feasibility of utilizing glass-reinforced plastic (GRP) as a construction material for vessels, piping, and ducting in the cold section of the carbon capture and storage (CCS) system. The research examined the potential of completely replacing metallic equipment and piping (such as carbon steel (CS), stainless steel (SS) or SS cladded CS) with GRP materials. The investigation revealed that complete substitution of GRP for certain CO2 service components, including the scrubber, pre-scrubber, tanks, piping, and ducting, may be feasible under specific process conditions. These process conditions encompassed temperatures below 100°C, pressures below 10 bar for piping, and pressures below 0.2 bar for the remaining components. Two fabrication methods, filament winding and contact molding, were employed throughout the design calculations and utilizing corresponding material properties. A chemical compatibility study by Shell, presented at the 2023 AMPP conference and expo (Paper # AMPP-2023-18832), confirmed that the selected resins used to prepare the GRP material are chemically compatible with the commercial amine formulation used for CO2 capturing at the same application limit identified for the present work. The study unequivocally confirmed that glass-reinforced plastic can be incorporated with confidence, adhering to the safety limits prescribed by international standards. This resounding validation strengthens the viability and applicability of GRP in the given context, bolstering its position as a reliable and suitable construction material.

Potential Distribution and Polarization Effect of Storage Tank Bottoms With Cathodic Protection Applied by MMO-Coated Titanium Anode Grids

Product Number: 51319-13315-SG

Author: Wei Cui

Publication Date: 2019

$20.00

Mixed metal oxide (MMO) is widely used as anode material for the cathodic protection of storage tank bottoms due to its advantages such as low consumption rate long service life and ideal current distribution. However with the elapse of service time the MMO CP systems have been found with such issues as low polarization level and uneven potential distribution threatening the operation safety of storage tanks. In this study numerical modeling and subscale experiment were chosen to clarify the main factors responsible for the aforementioned issues. The results indicated that the inadequacy of polarization and the lack of uniform potential distribution were related to a combination of multiple factors including the anode-to-tank bottom distance the impressed current level and the number of drain points. On the basis of these systematic analyses this paper conclusively proposes certain design principles and maintenance suggestions for the cathodic protection system of tank bottoms.

Hydrogen Embrittlement Under Cathodic Protection of Friction Stir Welded UNS S32760 Super Duplex Stainless Steel

Product Number: 51319-12994-SG

Author: Tiago Renck

Publication Date: 2019

$20.00

Hydrogen induced stress cracking (HISC) resistance of super duplex stainless steels is basically controlled by the material’s microstructure. Friction stir welding is a low heat input joining process that has the potential to maintain the base metal original resistance to HISC since it does not significantly alter the proportion of ferrite and austenite. This work evaluated the susceptibility to HISC under cathodic protection of friction stir welded super duplex stainless steel UNS S32760. Microstructure evaluation revealed a recommended proportion of ferrite and austenite phases as well a refinement of the overall stir zone microstructure. Fracture toughness tests in synthetic sea water under cathodic protection of -895 mVsce indicated that the microstructure of the stir zone is actually less sensitive to HISC than the microstructure of the base metal.Keywords: Friction Stir Welding (FSW) Super Duplex Stainless Steel (SDSS) UNSS32760 Stir Zone (SZ) Hydrogen Induced Stress Cracking (HISC)

While conducting overline surveys including Close Interval Survey (CIS), Alternating Current Voltage Gradient (ACVG), Direct Current Voltage Gradient (DCVG), Alternating Current Current Attenuation (ACCA) and Depth of Cover (DoC) in the Southeast Saskatchewan, Canada, a section of the cross Canada/US border Alliance pipeline, an unexpected CIS potential was encountered whereby potential measurements dipped, falling below the -850mV potential criteria, before rising again back into the range before the drop. The location of the potential drop occurred at a foreign crossing thus stray current was initially suspected. The field crew remained nearby while the foreign crossing owner representatives were notified of a possible interaction requiring further investigation. An interruption and influence analysis plan was put together to determine the nature of the influence on the Alliance DC Potential measurement circuit. This paper summarizes the preliminary analysis and test plan, the field measurements, and results.

Testing Heavily Cold Formed 22Cr Duplex Stainless Steel Exposed to Liquid Mercury to Assess Liquid Metal Embrittlement Susceptibility

Product Number: 51324-20319-SG

Publication Date: 2024

$40.00

Existing literature suggests that while 22Cr may not be susceptible to Liquid Metal Embrittlement (LME) when exposed to mercury at typical engineering strains, heavily cold formed 22Cr materials may be susceptible. The LME susceptibility from mercury of cold formed UNS S31803 was tested using four-point bend, slow strain rate, and interrupted slow strain rate techniques, simulating a range of strains from primarily elastic deformation of as-produced / as-welded pipe to high plastic deformation of cold formed pipe. Specimens were selected from the base metal, the weld metal / heat affected zone, and from pre-strained material simulating cold forming. The testing was conducted in the presence of mercury (only) at both ambient temperature and 40 °C. The passive film was intentionally disrupted by scratching at the initiation of the tests. The results of this testing did not indicate evidence of LME for any of the material / environment conditions tested.

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.
