Full-Scale Testing Validation and Quantification of Optimized Engineered Composite Repair Systems for Pipeline Repair

Product Number: 51319-13439-SG

Author: Matt Green

Publication Date: 2019

$20.00

For almost three decades composite repair technology has provided valuable alternatives to operating companies in maintaining the integrity of their high-pressure gas and liquid pipeline systems. Early adopters of the technology helped to push the usage of these beneficial materials to where they are today. As with all technology increased usage drives increased scope of usage and there have been extensive and comprehensive full-scale testing programs dedicated to pushing the boundaries and opening new defect repair options. These have been funded jointly by industry and manufacturers and have yielded successful results further showcasing the full range of benefits that composite materials can provide. Benefitting from this history and background allows for a better repair option based on experience and lessons learned. Development of new technologies methods and materials has been ongoing and results show improvements may be made by using lessons learned in conjunction with technologies now available.The contents of this paper focus and provide details on the development of specialized composite technologies for reinforcing anomalies such as corrosion and dents subjected to aggressive operating conditions. Additionally small-scale coupon-level testing results are used to characterize the effects of constitutive component changes in order to take the next steps prior to full-scaling including burst and cyclic pressure testing. Information is included on the initial design process used by engineers to optimize reinforcements using constitutive properties and insights from previous testing and research programs to guide the advancements in the understanding of the materials. Detailed test results and industry comparisons are included with information on how both coupon-level and full-scale test results can be used to assist operators in repairing and maintaining their pipeline systems using optimized composite reinforcing technologies.

Fundamental Approaches to Corrosion Resistant Alloy Development

Product Number: 51323-19410-SG

Author: Christopher D Taylor

Publication Date: 2023

$20.00

Integrated computational materials engineering (ICME) has provided materials developers with new virtual tools for exploring the space of novel materials. ICME is typically rooted in computation of phase diagrams (CalPhaD) using thermodynamic databases as well as thermodynamic data that can be generated from first-principles. CalPhaD provides the opportunity to determine stable materials compositions that may have targeted properties, which can be predicted using other computational search techniques, depending on the criteria of interest.

Fundamental Mechanisms of Mild Steel Corrosion in H2S Containing Environments

Product Number: 51319-12875-SG

Author: Aria Kahyarian

Publication Date: 2019

$20.00

The current understanding of the corrosion mechanisms in H2S containing environments considers the direct electrochemical reduction of H2S as the main contribution of this species to the corrosion process. Such an argument has been developed based on the distinctive behavior of cathodic polarization curves in H2S containing solutions as compared to the behavior observed in the solutions of strong acids or those in presence of other weak acids such as carboxylic acids and carbonic acid. The direct reduction of H2S is generally associated with the observation of a “double wave” in a cathodic polarization curve. In the present study the mechanism of cathodic currents in H2S containing acidic solutions was studied theoretically through a comprehensive mathematical model. The model includes a mechanistic description of main processes including mass transfer chemical reactions and electrochemical reactions. A quantitative analysis based on this model showed that all the characteristic behaviors previously associated with the direct reduction of H2S including the “double wave” behavior can be explained based on the homogeneous chemical dissociation of H2S as a weak acid and hydrogen ion reduction as the sole cathodic reaction. This analysis suggests that H2S is not a significant electroactive species and its main contribution to the corrosion process is through its buffering ability as a weak acid similar to other weak acids such as carboxylic acids and carbonic acid. In order to validate these mechanistic observations the results from this model were compared to existing experimental data from the open literature. The model was found to be able to capture the main characteristic experimental behaviors with reasonable accuracy further supporting this mechanistic argument.

Fundamentals of Making Good Decisions in Coatings Selection: Interpreting the Hidden Aspects of Accelerated Test Results

Product Number: 41212-722-SG

Author: Allen Zielnik

Publication Date: 2012

$20.00

When selecting among decorative or functional/protective architectural coatings many factors need to be considered; one key aspect is how long the product will last (weather). A “ten year” warranty is neither a guarantee of total replacement cost nor that all “ten year” products are created equal.

Further Advances In Paperless QA For Coatings Inspection

Product Number: 41211-604-SG

Author: JF Fletcher

Publication Date: 2011

$20.00

It is often said that inspection processes save money but that inspection reports cost money. The automation of inspection processes is an important cost saving that also leads to more time being allocated to the important task of inspection. There have been recent developments in both software and gauge design, which together make paperless quality assurance a reality for all protective and industrial coating applications.

Galvanic Cathodic Protection of Reinforced Concrete Structures

Product Number: 51319-13085-SG

Author: David Whitmore

Publication Date: 2019

$20.00

Cathodic protection is an effective technique to extend the service life of reinforced concrete structures. Historically impressed current cathodic protection systems have been used. These systems have been effective especially when they have been maintained. Galvanic cathodic protection systems offer the benefits of simplicity and reduced maintenance but are sometimes portrayed to provide only limited protection for a short period of time.This paper presents a series of case studies on the application of galvanic cathodic protection to provide long term cathodic protection to reinforced concrete structures. Case studies will include long term monitoring of field projects where cathodic protection criteria has been provided for over 15 years.

Stainless steel is selected for use in the municipal waterworks industry because of its inherent corrosion resistance properties. Designers oftentimes overlook the associated problems with coupling stainless steel with carbon steel metals. When these materials are electrically connected and placed into aqueous environments (immersion service) accelerated corrosion of the anodic carbon steel metal is initiated.
