On the choice of applied potential in ex situ testing of bipolar plate materials

Product Number: 51323-19547-SG

Author: Gareth Hinds

Publication Date: 2023

$20.00

Electrochemical energy conversion devices, such as fuel cells and electrolyzers, are widely recognized as an essential component of the transition to a low carbon economy. Polymer electrolyte membrane (PEM) variants of both technologies show particular promise due to their high current density, fast start-up times and low gas crossover rates. The main barrier to widespread uptake of these devices is their capital cost, which includes both raw material and manufacturing costs.

On the Effects of Test Frequency and Crack Driving Force on the Crack Growth Rate Behavior of 4340 Steel

Product Number: 51323-19429-SG

Author: W. Fassett Hickey, Matt Rahimi, Bob Cowan, Tony Nguyen

Publication Date: 2023

$20.00

Crack growth rate properties are used to assess life and integrity to determine appropriate operating conditions and service life; permissible flaw sizes; and defining minimum detectable flaw size requirements for non-destructive evaluations (NDE). In corrosion-fatigue environments, it is important to characterize the corrosion-fatigue crack growth behavior at a frequency that allows maximum interaction between the material and the environment to ensure that test conditions are suitably representative of service conditions and appropriately conservative.

A crucial step in qualifying a material for use in a critical engineering application in oil and gas production is quantifying the effect of test frequency on the FCGRs of the material in a representative environment.

On the weldability and corrosion resistance of alloy UNS N08827 – a further improvement of alloy UNS N08825

Product Number: 51323-18847-SG

Author: Julia Botinha, Martin Wolf, Helena Alves

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.

Optimization of Side-Groove Configuration of NACE Method D Testing

Product Number: 51323-19218-SG

Author: Hiroki Kamitani, Hisashi Amaya, Keiichi Kondo, Yuji Arai

Publication Date: 2023

$20.00

Corrosion resistance of low alloy steels for oil country tubular goods (OCTG) is a key point in order to select the suitable material. Among the corrosion test defined in NACE TM0177-2016, Double Cantilever Beam (DCB) testing in accordance with NACE TM0177-2016 Method D can be evaluated corrosion resistance as fracture toughness (K1ssc).

In this methodology, testing operators check the validity of the fracture surface to determine K1ssc in accordance with NACE TM0177 Method D 11.6. Edge cracking has been a big issue for industries.

Optimizing CP Life Extension Projects for Marine Offshore Structures

Product Number: 51323-19070-SG

Author: Cristina Peratta, Andres Peratta, Robert Adey

Publication Date: 2023

The complex of jacket structures and flowlines subject to retrofitting consists of 5 jacket structures and 8 subsea flowlines. The arrangement of assets and dimensions used in this work is designed to mimic the challenges posed by real complex scenarios. The complex has three central structures bridge linked (J1, J2 and J3) and two distant structures (J4 and J5) connected to J1 through underwater flowlines.

Optimizing Pipeline AC Threat Assessments using Computational Aided Engineering (CAE) Modelling

Product Number: 51323-19219-SG

Author: Christophe Baeté, Dr Olga Dolgikh

Publication Date: 2023

$20.00

There are several well documented reports and standards that detail what information is required to assist with an AC threat assessment. The Association for Materials Protection and Performance (AMPP) also details specific requirements and recommendations in terms of AC and the type of data and information required, in the NACE standard SP0177-2019, “Mitigation of Alternating Current and Lightning Effects on Metallic Structures and Corrosion Control Systems”. The documents and reports which address AC threat assessment, and which are available today, are all premised upon best engineering practices.

Optimizing Sol-Gel Coatings for Corrosion Protection of Braking Discs

Product Number: 51323-18872-SG

As far as the automotive sector is concerned, braking discs (BDs) are objects usually made of Grey Cast-Iron (GCI), i.e. a material exhibiting overall good mechanical properties and castability, but poor corrosion resistance. In particular, looking at the standard working conditions of a disc brake system, several environmental factors can cause and enhance GCI corrosion phenomena, such as: i) atmospheric moisture; i) ionic species contained in aerosols (e.g., chlorides and sulfates); iii) air differential corrosion caused by discs surface soiling by mud or other materials; and iv) galvanic coupling between the rotor and the braking pads.

Optimizing Sour Gas Qualification Testing – Modeling the Effects of Temperature and Total Pressure on H2S Fugacity, Activity, and Solubility Coefficients

Product Number: 51323-18762-SG

Author: Brent W.A. Sherar, Diana Miller, Hui Li

Publication Date: 2023

$20.00

Traditionally, sour severity of high-pressure, high temperature (HPHT) oil and gas production wells were assessed by H2S partial pressure (PH2S): The mole fraction of H2S in the gas (yH2S) multiplied by the total pressure (PT). While PH2S is appropriate for characterizing the sour severity of wellbores operating at low total pressures (e.g., PT < 35 MPa) and/or for highly sour systems (e.g., yH2S > 1 mol%), PH2S usually over-predicts the actual sour severity of HPHT systems, leading to sub-optimal material selection options.

Organic corrosion inhibitors for the prevention of stress corrosion cracking in 5XXX-series aluminum

Product Number: 51323-19223-SG

5XXX-series aluminum has been used in multiple naval vessels because it offers excellent strength to weight ratios, weldability and low cost. Although 5XXX series aluminum alloys generally provide excellent corrosion resistance, exposure to moderately elevated temperatures (e.g., solar exposure) results in sensitization due to precipitation of the beta phase (Mg2Al3) at the grain boundaries. The sensitization of marine grade aluminum and subsequent material degradation due to stress corrosion cracking (SCC) and intergranular corrosion (IGC) is a severe problem, causing expensive repairs and out of service time.

Performance of Distributed Galvanic Anode Systems in Bridge Structures

Product Number: 51323-19214-SG

Author: Ben Ricker, Max Nie, Liao Haixue

Publication Date: 2023

$20.00

Corrosion of reinforcing steel is recognized as the major cause of the deterioration of reinforced concrete structures. Exposure to de-icing salts, seawater and chloride-containing set accelerators, plays a significant role in reinforcing steel corrosion (Figure 1). When the chloride content at the rebar level exceeds the threshold for initiation of corrosion, the passivation protective film on the rebar surface is destroyed and a corrosion cell can form either on the same piece of rebar with anodic and cathodic sites adjacent to each other, or a macro-cell between two different layers of reinforcement.

Embedded galvanic anodes designed to protect reinforcing steel in chloride-contaminated concrete adjacent to concrete “patch” repairs were developed in the late 1990’s. The original concrete anode was puck-shaped and consisted of high purity zinc encased in a mortar formulated with high porosity and lithium hydroxide to maintain a pH greater than 14 to keep the zinc active over the life of the anode. This approach of a high pH mortar around the zinc to prevent anode passivation is commonly referred to as alkali-activation.
