Additive manufacturing (AM), commonly referred to as 3D printing, offers advantages over traditional
production methods, such as quick prototyping, short production runs and intricate, thin section,
microfluidic, variable composition, and low-waste designs. These exciting features are accompanied by
new challenges, such as higher costs, the possibility of variable quality, and inherently anisotropic
properties.

Existing AM technologies include 3D printing, rapid prototyping (RP), direct digital manufacturing (DDM),
selective laser melting (SLM), and direct metal laser Sintering (DMLS).

Evaluation of Thermally Diffused Zinc Coatings for Anti-galling Treatment for Rotary Shouldered Connections

Product Number: 51323-19361-SG

Publication Date: 2023

Rotary shouldered connections are commonly used in the oil and gas industry as the preferred connection method between drill string elements. A wide variety of materials are used in the drillstring make up, each with different properties and galling behavior. Non-magnetic austenitic stainless steel (AuSS) alloys are frequently used in measurement/logging-while-drilling (M/LWD) tools. CrMnN AuSS were commonly used to produce M/LWD tools and have decent galling resistance but are prone to failure due to stress corrosion cracking (SCC) during operation.

Experimental Characterization of Grain Boundary Fracture Properties in a FeCr12Ni26Si3 Austenitic Stainless Steel Oxidized in PWR Environment

Austenitic stainless steels are used for the core internal structures (bolts, baffles, formers) in Pressurized Water Reactors (PWR). During operational service, baffle to former bolts have been observed to undergo Irradiation-Assisted Stress Corrosion Cracking (IASCC), which is characterized by intergranular cracking. IASCC results from the material corrosion susceptibility, the microstructural changes induced by irradiation, the corrosive media and the mechanical loading. Numerous studies have been conducted to evaluate the complex interplay between the different factors, mostly focusing on InterGranular Stress Corrosion Cracking (IGSCC) of pre-irradiated samples in PWR environment. In particular, the oxidation behavior of grain boundaries and the mechanical loading of grain boundaries have been assessed in details. Depending on the oxidation time and the GB nature, oxide penetration along GB has been observed. The intergranular oxide is composed of (Nix,Fe1-x)Cr2O4 spinels. However, all grain boundaries (GBs) do not have the same oxidation behavior, and it has been reported that high angle grain boundaries show higher oxidation susceptibility than special grain boundaries. Radiation induced segregation at grain boundaries might also lead to higher susceptibility to intergranular oxidation. Irradiation also modifies the deformation mechanisms in austenitic steels resulting in strain localization which is believed to be an important factor in IASCC initiation as it can lead to local increase of the stress due to dislocation pile-ups at GB.

External Chloride Stress Corrosion Cracking (Cl-SCC) of Valve Bonnet 304 Austenitic Stainless Steel Stud Bolts

Product Number: 51324-21176-SG

Chloride stress corrosion cracking (Cl-SCC) is known to occur in austenitic stainless steels operating at temperatures above 60 °C (150 °F). This paper, however, will discuss external Cl-SCC failures that occurred at ambient conditions. These failures occurred in stainless steel grade 304 bolts used as valve bonnet stud bolts. The failure caused total disengagement of the valve bonnet. These valves were located approximately 1 km from the seashore. In addition, the valves were located underneath a seawater deluge system used for fire protection which was periodically tested resulting in the valves being wetted by seawater. This paper provides details related to the materials, environmental conditions and mechanical properties of these bolts and provides recommendations to avoid such failures in the future.

Failure Analysis of High Temperature Plate Heat Exchangers in Converter Section of Sulfuric Acid Regeneration [SAR] Unit

Product Number: 51323-19420-SG

Author: Sudharsanan Soundararajan

Publication Date: 2023

$20.00

A Sulfuric Acid Alkylation [SAA] unit in a refinery converts olefins and butane to high octane alkylate using highly concentrated sulfuric acid as a catalyst. The function of this Sulfuric Acid Regeneration [SAR] unit is to regenerate spent sulfuric acid from alkylation process into clean sulfuric acid of 99.2% concentration, which is then recycled back into the SAA unit. The process of SAR can be classified in to following four steps:

• Formation of SO2 by the decomposition of Spent acid and combustion of H2S.
• Cooling and Purification of the SO2
• Conversion of SO2 to SO3
• Absorption of SO2 in H2SO4

Failure of Heat Exchanger Cooling CO2 from a Pre-Combustion Unit

About a month after commissioning, a decrease in pH of the cooling water in the plant was observed. This meant that CO2 has leaked into the cooling water in one of the coolers. Two months after commissioning, about 15% of tubes in one cooler downstream of the reactor were plugged after inspection results showed that they have leaked.

Directional drilling tools for oil and gas exploration is one industrial application where Manganese (Mn)-stabilized austenitic stainless steels with different amounts of other alloying elements like Chromium (Cr), Nickel (Ni) and Molybdenum (Mo) have found extensive use in spite of the demanding requirements in terms of mechanical properties and corrosion resistance. The limited resistance of this type of austenitic stainless steels to environmentally assisted cracking (EAC) in hot chloride (Cl-)-containing environments is well known. Chloride-bearing environments at elevated temperatures are not uncommon in drilling operations and can indeed challenge the EAC-resistance of CrMn-stainless steels

Historical Perspective of Corrosion by Potable waters in Building Systems

Product Number: 93509-SG

Author: Arthur Cohen

Publication Date: 1993

$20.00

Corrosion can be a costly and annoying concern in a building's potable water

The forms of corrosion that can occur include:

1) General Corrosion

2) Pitting Attack

3) Concentration Cell Corrosion

4) Dealloying

5) Erosion Corrosion

6) Galvanic Corrosion

These corrosion forms can be avoided by a number of techniques including materials selection, system design and chemical treatment of the water.

Coatings, sometimes in conjunction with cathodic protection, have been used to mitigate the corrosion of storage tanks in building systems, but are not addressed in this paper.

Influence of Operating Temperature on the Corrosion of UNS S30400 Steel under Catalytic Hydrodeoxygenation of Pyrolysis Oil by Supercritical Ethanol with In-situ Hydrogen Source

Bio-oils are renewable and clean energy sources, which can be used to partial or completely replace fossil fuel. Fast pyrolysis is a promising and by far the only industrially realized approach to convert dry biomass into biofuels, particularly the liquid bio-oils. However, the poor quality of fast pyrolysis oil including thermal instability, high viscosity and acidity, high oxygen and water content, and low heating value makes it hard to be directly used as transportation fuels.

During drilling operations, the components in the drill string including the bottom hole assembly (BHA) remains in permanent contact with the drilling fluid. Therefore, besides non-magnetic properties and high strength the corrosion resistance of the materials utilized for the BHA plays a decisive role specially in applications involving harsh environments. In fact, strain-hardened CrMn-austenitic steels commonly used in directional drilling technology show a high susceptibility to pitting corrosion and environmentally assisted cracking in drilling fluids with a high chloride (Cl-) content at elevated temperatures.

This paper focuses on the risk of corrosion of austenitic stainless steels following exposure to oxygenated chloride containing waters, such as during hydrotesting or commissioning activities.

Hydrotesting is an activity typically occurring during construction intended to confirm the component's structural integrity for the design and operating pressure. The commissioning phase can use the same water in multiple systems for dynamic commissioning.
