Air Cooler Plug Gaskets Leakage During Startup

Product Number: 51320-15197-SG

Author: Cathleen Shargay, Sarah Radovcich, Amish Jani, Kuntak Daru, Jigneshkumar J. Desai

Publication Date: 2020

$20.00

Severe leakage on a high percentage of the plug gaskets on a high alloy air cooled heat exchanger during or shortly after initial startup has occurred in only a small percentage of air coolers, but has resulted in costly replacements and unit shutdowns. These problems have occurred with 304L stainless steel (SS), 316L SS and Nickel 200 gaskets, although each material also has many successful applications. The contributing factors to the leakage has included corrosion, galling and/or inadequate manufacturing steps. This paper summarizes a number of case histories and gives their root causes and solutions. The pros and cons of various gasket materials and design options are discussed, along with a proposal for additional requirements to be added to industry standards which would minimize the risks of these problems.

Assessing Susceptibility of Insulation Materials to IGSCC under Hot and Wet Conditions: A Novel Test Method

Product Number: 51324-20920-SG

Author: Yuan Li; Lisa Sopkow; Simon Yuen; Matthew Krantz; Tony Lam

Publication Date: 2024

$40.00

Intergranular stress corrosion cracking (IGSCC) in above-ground carbon steel pipelines has been identified as a distinct mode of failure, different from the typical neutral pH and high pH SCC observed in buried pipelines. This form of SCC occurs under specific conditions, including operating temperatures ranging from 70°C to 190°C, exposure to wet mineral wool insulation, and insulation installations dating from post-2003. The affected carbon steel grades have included API 5L or CSA Z245.1 with specified minimum yield strength (SMYS) of 52 ksi or higher, as well as A106 Gr B, A234 WPB, and A516 Gr 70. Both field and laboratory tests have been conducted in the past to investigate this phenomenon. However, the underlying mechanism remains unclear. This paper presents a summary of the results obtained from various analytical methods, including chemical analyses, cyclic potentiodynamic polarization (CPP) testing, field crack inspections, U-bend autoclave tests, and a novel wet/dry cyclic test. It outlines the gaps in our understanding and highlights key findings that contribute to a better understanding of SCC in this specific context. Additionally, this paper discusses the development of test methods for screening susceptible materials, which is crucial for preventing failures related to intergranular SCC in above-ground carbon steel pipelines.

Characterizing Properties and Stress Corrosion Cracking Resistance of Alloy 718 via Additive Manufacturing

Product Number: 51323-19117-SG

Author: Karthik Krishnan

Publication Date: 2023

$20.00

UNS N07718 (Alloy 718) is a precipitation-hardened Nickel alloy widely used for various components in oil and gas production service where a combination of high strength, good cracking and corrosion resistance is needed. API 6ACRA provides heat treatment windows and acceptance criteria for wrought Alloy 718 in these oil and gas production environments, in which the heat treatment is intended to obtain high strength desired for applications in combination with good environmental performance.

Additive Manufacturing (AM) is increasingly becoming a source of design, fabrication of complex components where machining from wrought material would be very cumbersome or introduced complicated welding processes.

Comparing Stress Corrosion Cracking Initiation Times of Sensitized 304 Stainless Steel in KOH And LiOH Primary Water Chemistries with High Levels Of Dissolved Oxygen

Product Number: ED22-18341-SG

Author: Stuart Medway, Peter Chou, David Tice

Publication Date: 2022

$20.00

The testing described in this paper is part of a wider initiative by the Electric Power Research Institute (EPRI) to perform a due-diligence assessment to support possible application to plants and demonstrate the use of potassium hydroxide (KOH) in western Pressurized Water Reactors (PWRs). Lithium hydroxide (LiOH) is used in the primary coolant loop of PWRs to modify the pH of the coolant water. LiOH is most commonly used as the alkalizing substance as 7Li is already present in the water
chemistry as a by-product of the neutron reaction with boron (10B). To reduce the risk of accelerated corrosion of the Zircaloy fuel cladding material, there is an upper limit of 3.5 ppm for 7Li, although standard starting chemistry is typically 2 ppm. The amount of lithium is subsequently reduced during operation as the required level of boron is reduced due to fuel burnup through the fuel lifecycle.

Comparison of stress corrosion cracking behavior of Fe13Cr5Ni- and Fe17Cr5.5Ni- based high chromium stainless steels in HPHT CO2 environments

Product Number: 51320-14695-SG

Author: Yameng Qi, Chunxia Zhang, Zhonghua Zhang

Publication Date: 2020

$20.00

The stress corrosion cracking (SCC) behavior of Fe13Cr5Ni- and Fe17Cr5.5Ni-based alloys in HTHP CO2 environments was investigated through slow strain rate tests (SSRT) and electrochemical methods. The results show that a remarkable decrease in tensile strength and elongation to failure was observed when testing in CO2 environment as compared with air. Fe17Cr5.5Ni-based alloys possessed better SCC resistance than Fe13Cr5Ni-based alloys. The increase of Cr and Ni content tended to enhance the resistance to SCC and pitting corrosion. The SCC behaviors of Fe13Cr5Ni- and Fe17Cr5.5Ni-based alloys were closely associated with the repassivation capacity and the resistance to pitting corrosion.
