Comparing AC Study Techniques In Addressing AC Corrosion Risk

Product Number: 51322-17735-SG

Author: Perry Ross

Publication Date: 2022

$20.00

AC interference studies have become increasingly popular in an industry where shared right of ways have increased and there has been a better understanding of how AC interacts between pipelines and powerlines that are collocated with each other. While modeling software for AC interference studies have been developed since the 1990s, advancement in AC interference processes have occurred as more has been learned over the years. When performing an AC interference study there are three steps that need to be completed: field data collection, modeling, and mitigation design. Within this paper, we can compare a project from ten years ago to a project from today to understand the developments that have been made over the course of time to improve the way we develop our mitigation designs.

Comparison of Two ASTM E1820 Standard Fracture Toughness Test Methods for LAS Material in Deaerated Saltwater under Cathodic Protection

Low alloy steels (LAS), frequently used for pressure-containing equipment in subsea applications, are susceptible to hydrogen embrittlement when exposed to seawater environments under cathodic protection (CP), which can result in a reduction of toughness and ductility. Fracture toughness, which is an indication of a material’s resistance to crack propagation and unstable crack growth, is often determined from laboratory tests for design verification analysis or fitness-for-service applications. In hydrogen charging environments such as deaerated saltwater under CP, the fracture toughness is typically measured using either an unloading compliance (UC) or a rising displacement DCPD test method, both of which are described for air testing in the current ASTM E1820 standard. In this study, slow load rate fracture toughness tests on compact tension C(T) specimens using both test methods on the same heat of material are performed and compared. The tests are performed in a deaerated saltwater under CP environment using the same targeted K-rate of 0.005N/mm3/2/s. The UC test method is performed with a clip gauge for load-line displacement (LLD) and in-situ crack depth measurement, and the rising displacement DCPD test method infers LLD indirectly and uses DCPD for crack depth prediction. A comparison of the test results indicated a 35-65% increase in the calculated ???????? fracture toughness of the material when using the rising displacement DCPD test method.

Composite Repairs And Cathodic Protection

Product Number: 51322-17825-SG

Author: David B. Futch, Davie Peguero, ,\Casey Whalen, Stephen Barnett

Publication Date: 2022

$20.00

The motivation for this work was to perform a comprehensive test program to investigate several commercially available composite repair systems and their interactions with cathodic protection. Multiple test methods were utilized to prove there remains a low probability of shielding for composites of typical thickness and in a typical environment. This work will also discuss how results from current industry qualification tests (such as those specified in ASME PCC-2) can be considered when making long-term decisions regarding the effects of cathodic protection on composite repairs and the pipelines on which they are installed. This paper provides an innovative approach to test and validate the interactions of cathodic protection with several commercially available composite repair systems.

Conditioning Of Steel Surfaces With Various Abrasive Blast Media And Effect On Coating Performance

Product Number: 51322-17888-SG

Author: Andrew Recker, Darryl Corbin, Yuxin Zhai

Publication Date: 2022

$20.00

Over the past few decades surface preparation standards have been implemented to provide guidance on determining the necessary surface cleanliness for specific applications. Prior to such standards, surfaces were prepared as they saw fit at the time of application which created high variability in performance of the protective coating. Since the standards were developed, the resulting performance consistency has become increased significantly. Such standards discuss a visual inspection of the steel after an abrasive material has been used to remove scale, rust, and other discoloration soils.

Impressed current cathodic protection (ICCP) for reinforced concrete structures has been installed on numerous bridges and wharves in Australia over the past 40 years. The exposure conditions at the majority of these bridges and wharves made them more susceptible to chloride-induced corrosion.

The ICCP systems in Australia are designed, installed and monitored in accordance with the global cathodic protection standards such as AMPP Standard SP 0290-2019, International Standard ISO 12696:2022, and Australian Standard AS 2832.5 – 2008 (R2018).

Corrosion Assessment and Repair for Aging Concrete Infrastructure

Product Number: 51324-20860-SG

Author: Stephen W. Foster; Terry McGovern

Publication Date: 2024

$40.00

An overview of various assessment techniques is discussed, including visual assessment as well as more detailed destructive and non-destructive assessment techniques, such as mechanical sounding, half-cell potential surveys, corrosion rate testing, material sampling, and laboratory analyses. Digital data collection techniques and the use of assessment data to develop service life and durability predictions based on the properties gathered by an in-situ assessment are also presented. Based upon the assessment results, the appropriate mitigation strategies can be selected. Several repair and mitigation strategies for reinforced concrete structures are discussed, along with the considerations involved with selecting each system with respect to cost, maintenance, and potential service life implications. Representative case studies will illustrate how these tools have been used for water and wastewater infrastructure.

In gas-oil separation plants (GOSPs), multiphase crude is separated, degassed and then dehydrated before being shipped to stabilization plants for further processing. Typically, in ageing oil fields, the crude is accompanied by large volumes of formation water that is separated in GOSPs using three-phase production traps, which are large horizontal vessels, using a gravimetric separation process where water collects and settles at the vessel’s lower part.
