Insulation Driven Intergranular Stress Corrosion Cracking of Carbon Steel

Product Number: 51324-20914-SG

Author: Matt Krantz; Yuan Li

Publication Date: 2024

$40.00

Over the past decade, an increasing number of intergranular stress corrosion cracking (IGSCC) incidents have been observed on carbon steel assets operating in Alberta, Canada. At the time of publication, over 128 distinct cracks have been identified on 26 assets spanning at least 5 operators. All incidents have occurred on uncoated carbon steel operating between 70 °C and 190 °C and exposed to wet mineral wool insulation. Both piping and pressure vessels have been affected. Cracking has been isolated to assets with mineral wool insulation produced after 2003; however, a specific change to mineral wool composition in this timeframe has not been identified. The purpose of this paper is to provide a summary of incidents and investigations that have been reported to date and to update the environmental conditions (window of susceptibility) where insulation driven intergranular stress corrosion cracking has been observed. By drawing attention to this issue, it is the authors’ objective to increase awareness and determine if similar cracking incidents are occurring in other geographical regions.

Investigating Crack Initiation and Propagation from Hard Spots In TMCP Steels Exposed to Wet Sour Environments

Product Number: MECC23-20109-SG

Author: Maslat Al-Waranbi; Saad M. Al-Muaili; Khalid BaBakri

Publication Date: 2023

$20.00

Hard spot cracking is a type of sulfide stress cracking (SSC), which is a common type of Hydrogen
Embrittlement (HE). The embrittlement by SSC is attributed to the hydrogen atoms (H+), as corrosion byproduct, that permeate/diffuse through the metal with the presence of H2S. Then, when hydrogen atoms get entrapped at specific microstructural configurations, material ductility will be impaired and material will be embrittled [2].

Metallurgical Analysis of 30-Inch Pipe Containing an Internal Crack

Product Number: 51324-20700-SG

Author: Sudhakar Mahajanam; Chris Miller; Scott Harding; Sean Moran

Publication Date: 2024

$40.00

Pipeline defects are routinely found in the oil and gas industry. Most often they are minor, and do not affect the integrity and safety of the pipeline. However, in some cases, identifying and repairing critical defects is mandated to ensure long term integrity, which also entails choosing an appropriate repair technique. In this case study, we present a metallurgical examination of a 1949-vintage Grade X52 pipe containing an internal crack that was first identified at a client site. Laboratory examination confirmed that the feature was a pre-existing imperfection or defect, which had been weld repaired around the time of manufacturing or installation. Grinding marks and a distinct weld zone with three welding passes were observed in the region surrounding the crack. Scanning electron microscope (SEM) fractography of the crack surface indicated the presence of columnar grains close to the inside surface that are typical of a carbon steel weld. Energy dispersive x-ray spectroscopy (EDS) analysis indicated that the corrosion products consisted of iron

NACE SP0110-2024, Wet Gas Internal Corrosion Direct Assessment (WG-ICDA) Methodology for Pipelines

Product Number: NACE SP0110-2024

Publication Date: 2024

$109.00

This standard practice outlines a methodology to assess pipeline integrity because of the threat of internal corrosion for onshore and offshore pipelines and other piping systems that normally carry water-saturated or undersaturated natural and/or raw gas with condensed water, or with water and liquid hydrocarbons, termed wet gas internal corrosion direct assessment (WG-ICDA).

NACE SP0113-2023, Pipeline Integrity Management: Methods Selection and Implementation

Product Number: NACE SP0113-2023

Publication Date: 2023

$109.00

This standard practice provides guidance on selecting and implementing the Pipeline Integrity Management (PIM) methods (i.e., technologies and processes) to assess and to mitigate threats to pipeline integrity. Predominant threats to pipeline integrity are external corrosion (EC), internal corrosion (IC), stress corrosion cracking (SCC), mechanical damage (first, second, and third party or vandalism), equipment malfunctioning, manufacturing anomalies, construction anomalies, incorrect operations, weather-related, and external forces. The standard is focused on the “selection” and “implementation” of methods and best practices to manage pipeline integrity, but not necessarily on defining all aspects of PIM programs.

Novel HDD Mechanical Protection for Reduced Holidays

Product Number: 51323-19303-SG

Author: Neil Pittman, Paul Phillips, James M. Fistler

Publication Date: 2023

$20.00

Horizontal directional drills (HDD) have become an essential pipeline construction tool for crossing spans of the right of way with obstructions such as wetlands, rivers and streams, railroads, roads, businesses, and high consequence areas (HCA). This trenchless technology allows a pipeline to be installed without open cutting the ground. Prior to any construction, geological surveys with core samples are performed to determine the optimum route for the HDD (Figure 1).
