Effect of Heat Treatment Temperature on the Corrosion Protection Performance of Thermal Sprayed Aluminum Coating

Product Number: 41214-844-SG

Author: KyungJin Park, SangKyu Ryu, MyoungHo Ahn

Publication Date: 2014

$20.00

In the present study, thermal effects on the corrosion behavior and corrosion protection performance of TSA coating were investigated using various electrochemical techniques. Heat treatment at higher temperature induces more cracks in the sealer and aluminum coating. Water and corrosive species (e.g., Cl-) penetrate through the cracks, resulting in corrosion of steel substrate.

Effect Of Steel Surface Profile Peak Density On Rust Creepage

Product Number: 51322-17584-SG

Author: Russell Draper, Michael Beamish

Publication Date: 2022

$20.00

The spread of disbondment or corrosion from a scribe or holiday in a coating film, for which the terms rust creepage or undercutting are used in this paper is an important mechanism of coating degradation. The mechanism of rust creepage has been well studied by several authors who concur that the mechanism is driven by electrochemical reactions15. The reactions occurring at the discontinuity in the coating (scribe or holiday) involve an anodic reaction in which iron is dissolved. Adjacent to the anodic region, under the coating, a cathodic reaction occurs in which oxygen is reduced to hydroxyl ions.

Electrode Tool Logging Approaches for Casing Inner Coating Monitoring

Product Number: 51320-14795-SG

Author: Gang Guo, Qiongwei Li, Bihai Cheng, Wenwei Lu,Lihua Yang, Zhiping Zhou

Publication Date: 2020

$20.00

To control the casing's severe CO2 inner corrosion and minimize damage to oil wells drilled into the Yan'an formation of Jurassic reservoirs; internal plastic coating was applied to the portion of the casing below the dynamic liquid level (nearly 700 m) for each of the more than 4000 wells drilled over the last 10 years. Considering the cost factor, it was not economic for the whole wellbore to have internal coating, so only the section with serious internal corrosion was internally coated with a modified epoxy-phenolic.

This kind of modified epoxy-phenolic coating has excellent mechanical and anti-corrosion performance. But it’s difficult to analyze the long term aging or local mechanical damage of downhole inner coating. New approaches by electrode logging tools have been studied for monitoring the inner coating.

Evaluation of a Hydrophobic Coating Material for Downhole Application, Lab vs. Field Evaluation

Product Number: 51324-20756-SG

Author: Tao Chen; Feng Liang; Frank Chang; Qiwei Wang

Publication Date: 2024

$40.00

A hydrophobic electroless nickel-phosphorus (ENP) coating material has been developed to reduce corrosion-induced iron sulfide scale deposition. The ENP coating has several key advantages to provide corrosion resistance for sour oil and gas applications, including a level of phosphorus imparting superior corrosion resistance in a sour gas environment, a tailored phosphorus level providing a range of super hydrophobic microstructures, and a second material introduced and embedded in the ENP coating during the coating process to impart desired properties such as wear and erosion resistance. The coating material has been qualified through a series of evaluation tests carried out in the lab, including iron sulfide scale formation under HTHP, coating adhesion tests, explosive decomposition, formation of heazlewoodite (Ni3S2), etc. The coating material was installed in downhole completion tubing through a downhole corrosion and scale monitoring (DCSM) tool to monitor coating stability, corrosion, and scaling under real downhole flow conditions in a sour gas well over 3 months. Overall, the field testing has demonstrated that this newly developed coating material can effectively protect the metal coupon against corrosion and iron sulfide deposition. However, the abrasion of the formed surface layer of Ni3S2 and blistering might be a concern for a long-term field application. This paper will comprehensively compare the coating performance evaluated in the lab and field conditions. Long-term evaluation under real field conditions is highly recommended to qualify the coating material for large-scale application in the downhole.

Evaluation of Various IMM/IC Coating Systems in Terms of Corrosion Protection

Product Number: 51324-20414-SG

Publication Date: 2024

$40.00

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.

Extreme high-speed laser application of coating to prevent hydrogen embrittlement in metals

Product Number: 51323-19546-SG

Author: Yingwei Wu, Josh Barras, Jhonattan Gutjahr, Carl Hauser, Yuanbo T. Tang, Roger C. Reed, W. Mark Rainforth

Publication Date: 2023

$20.00

Hydrogen as a promising alternative energy source that is forecasted to potentially transform future power generation toward new-zero. However, its widespread adoption has proven challenging owing to difficulties around storage, transportation, and usage due to catastrophic failures i.e. hydrogen embrittlement (HE). This is particularly severe for high-strength structural steel that must be designed against fatal fractures; it is also relevant to parts that are not designed for hydrogen exposure due to the prevention of accidental spill or leakage.

High Performance Liquid Epoxy Polymer Concrete: 30 Year Benchmark Solution - Aro Coating Selection Criteria

Product Number: 51324-20613-SG

Author: Mario Moreno; Jesus Corona

Publication Date: 2024

$40.00

Liquid Epoxy Polymer Concrete has been for the past decades the preferred solution for HDD applications in North America. This paper follows 30 years after Stephanie Powers' publication and highlights the advantages of the Liquid Epoxy Polymer Concrete technology as an abrasion-resistant coating that has been used in thousands of directional drill applications for oil, gas, and water pipelines. There has been an evolution in the understanding of technology and its application. The paper looks back on successes and lessons learned for this technology. Based on field and laboratory testing, the paper develops a comparative analysis with other alternative technologies such as dual-layer FBE-ARO, 3LPE, and the new composite technologies. The paper concludes by suggesting a correlation between project/operation parameters and product selection as well as several successful case studies of the Liquid Epoxy Polymer Concrete technology.
