Over the past twenty years, additive manufacturing (AM) has gradually emerged as an important commercial manufacturing technology for the production of components, particularly complex and highvalue metallic components. AM enables the layer-by-layer rapid manufacturing of near-net shapes using 3D computer-aided design data and typically minimizes raw-material wastes.

On The Performance Of UNS S32100 vs N08825 Expansion Compensator Materials In Geothermal Applications

Product Number: 51322-17790-SG

Author: Keith Lichti, Soroor Ghaziof

Publication Date: 2022

$20.00

Geothermal fluid pipelines experience temperature changes on startup and shutdown that can be of the order 300 °C. Carbon steel pipeline design can include expansion loops and direction changes to allow for thermal expansion and contraction for the long lengths of pipeline commonly used from geothermal production wells to the geothermal power station and from the station to reinjection wells. In some instances, expansion compensators are used where there is insufficient area for such loops or where the pipe diameter is prohibitively large.

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.

On-Site Parameter Measurements And Corrosion Coupon Tests Of Buried Pipeline Subject To AC Interferences Of High Speed Railway

Product Number: 51322-17725-SG

Author: Le Chen, Jianjun Li, Yanxia Du, Nianpei Tian, Jia Liu, Yi Liang

Publication Date: 2022

$20.00

With the rapid development of the economy and acceleration of urban modernization, many high-speed railways and buried pipelines have been built in China. Due to the limitation of space or geographical location, high-speed railways are often constructed in parallel or crossing with long-distance pipelines in some locations. The interference of high-speed railways on pipelines is the result of inductive and conductive coupling, which brings about AC corrosion and other safety issues.

Optimisation Of Hydrogen Stress Cracking Resistance Of High Strength Precipitation Hardened Nickel Alloys

Product Number: 51322-17960-SG

Author: Stephen McCoy, Brian A. Baker, William MacDonald

Publication Date: 2022

$20.00

The Precipitation Hardenable (PH) Nickel alloys N09925, N07718, N09945, N09946 and N07725 are widely used for critical downhole oil field applications such as high strength tubing hangers and completion equipment. The materials are particularly useful in High Pressure/High Temperature wells where high strength and corrosion resistance are required in H₂S containing production fluids. Over the last 20 years a limited number of field failure investigations in PH Nickel alloys have been related to the presence of sufficient amounts of intergranular precipitates promoting hydrogen embrittlement, which results in brittle cracking of UNS alloys N07718 ^3,4 and alloy N07725⁵ and N07716⁶.

Optimizing Sol-Gel Coatings for Corrosion Protection of Braking Discs

Product Number: 51323-18872-SG

Author: Nicola Nocera, Bozhena Tsyupa, Marco Bandiera, Mary Angel Abello, Pietro Della Bella, Alessandro Piglione, Andrea Bonfanti, Federico Bertasi

Publication Date: 2023

$20.00

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.

Overview Of Scale Issues And Treatment For Sour Water Strippers

Product Number: 51322-17549-SG

Author: Haiping Lu, Swamy Margan, Bill Watson, William Mansfield, Jim Kiolbassa

Publication Date: 2022

$20.00

Sour water stripping is used to remove ammonia (NH₃) and hydrogen sulfide (H₂S) from sour water streams coming from many operation units to condition it for discharge or reuse.^1-3 In a complex refinery, most of the sour water comes from distillation, fluid catalytic cracking, catalytic reforming, coker and acid gas removal units, with many other operations contributing to the balance. The different streams are usually collected in a surge tank for centralized processing via a heat exchanger and a single stripper column, or two in series.

Performance Of Additively Manufactured Alloy 718 In Sour Service

Product Number: 51322-18029-SG

Author: Liu Cao, Christopher Taylor

Publication Date: 2022

$20.00

Alloy UNS N07718 (hereafter abbreviated as 718) is one of the most versatile precipitation-hardened nickel-based corrosion-resistant alloys (CRAs) used for both surface and sub-sea components in oil and gas production service. API 6ACRA¹ provides heat treatment windows and acceptance criteria for 718 in these oil and gas production environments, in which the heat treatment is intended to obtain high strength and to minimize the formation of δ-phase at grain boundaries. As pointed out in NACE MR0175 Part 3² (Table 1), field failures of 718 components in sour service are primarily related to stress corrosion cracking (SCC) at elevated temperatures and hydrogen embrittlement in the lower temperature range. The latter is specifically called galvanically induced hydrogen stress cracking (GHSC or GIHSC), which is typically caused by atomic hydrogen uptake from galvanic corrosion or cathodic protection (CP) when 718 is used with steel components in a seawater environment. CP is normally used to protect steel component from corrosion in subsea environments.

Performance Of Laser Additively Manufactured Alloys In (Light Water) Reactor Environments

Product Number: ED22-17282-SG

Author: Bogdan Alexandreanu, Xuan Zhang, Yiren Chen

Publication Date: 2022

$20.00

Nuclear power has been the largest source of carbon-free power in the U.S. (and much of the developed world) for almost a half century. As such, in the U.S. today, nuclear power plants of the Light Water Reactor (LWR) design generate 20% of all electricity, comprising over half of carbon-free electricity generation. In order to meet the short-term 2030 greenhouse gas emission reduction target, the existing nuclear fleet will play an important role, while the development and deployment of advanced reactors such as the small modular reactors (SMR) of the LWR design can be accelerated.
