Straining at a Gnat and Swallowing a Camel: Safety and Performance Issues with Two - Part Urethane Finish Coats

Product Number: 41206-272-SG

Author: Mike O’Donoghue, Ron Garrett, V.J. Datta

Publication Date: 2006

$20.00

An escalating amount of negative press on the tried-and-true polyurethane finish coats has arisen due to concerns with their free-isocyanate content. This paper explores performance aspects of polyurethanes with respect to their UV resistance properties, and safety issues associated with polyurethanes as a function of their precursor isocyanate molecules.

Strategies for Reducing Climate Control Costs Utilizing New Technologies

Product Number: 41215-881-SG

Author: Russell Brown

Publication Date: 2015

$20.00

This paper will discuss strategies for utilizing dehumidifiers and climate control equipment on blast and coat projects and will demonstrate how by their implementation, the contractor can be more successful by reducing overall job costs. We will take a brief look at the current core of climate control offerings. We will then examine how the manufactures of climate control equipment have tried to keep in step with the demands from the industry and of course, the customer.

Strategies to Control and Minimize Corrosion and HIC Damage Found in Amine Absorber HIC Resistant Steels

Product Number: MECC23-20093-SG

Author: Gerrit M Buchheim, P.E.; Olavo C Dias

Publication Date: 2023

$20.00

As environmental sulfur limits become more stringent, there has been a recent surge in preferential and localized corrosion in amine units. This has occurred even with HIC (Hydrogen Induced Cracking) resistant steels and in equipment where velocity limits are not exceeded.
Amine absorbers and associated rich amine piping particularly around the welds, downcomers and other turbulent locations are particularly vulnerable.

Stray Current Corrosion Risks and Case Histories in Communication Tower and Electric Transmission Applications

Product Number: 51320-14770-SG

Author: Anil Kumar Chikkam, Freddy Avendano and Peyman Taheri, Mehrooz Zamanzadeh, Nitesh Ahuja, Kevin Groll, Ben Jessup

Publication Date: 2020

Stray current refers to electric current that flows elsewhere rather than along its intended path. Stray current is a well-known factor in pipeline maintenance and has been discovered to be an important consideration in communication and electric transmission structure maintenance. Corrosion caused by stray current is frequently many magnitudes greater than corrosion that occurs naturally in soil. Stray current may accelerate corrosion on guy anchors of communication towers and electric transmission towers which could lead to reduced service life or catastrophic failure.

In this paper, stray current corrosion risk for galvanized guy anchors is discussed in detail. Identification by structure-to-soil potential measurements is discussed. Stray current case studies are presented. Overall, this paper demonstrates that while stray current corrosion is a significant risk for guyed telecommunication and electric power structures, it can be detected and mitigated. This paper is an overview of the commonly accepted practices of stray current detection and mitigation used today.

Stray Current Guidebook for Rail Transit and the Lessons Learned

Product Number: 51319-13221-SG

Author: Saud Memon

Publication Date: 2019

$20.00

Stray current is a major concern for the track utility and infrastructure owners in the vicinity of thedirect current (dc) powered rail transit system.Stray current leakage and the corrosion caused by these currents is more of an issue in low resistivity soils and embedded tracks which typically run through major traffic areas city centers and tread between utility lines that require the rail to be continuously isolated to provide superior track-to-earth resistance.The absence of specific national stray current control and/or mitigation standard or guideline in the U.S necessitates the need to produce contemporary standards and guiding principles for the transit providers and corrosion consultants to match the advancements made in other sectors of the rail transit system. The author thus prepared a guidebook for the Transit Cooperative Research Program (TCRP) documenting best practices for those seeking guidance on design maintenance and testing of stray current control for dc powered rail transit systems. The guidebook is a resource that can be put into use immediately by stray current corrosion consultants transit agency owners and corrosion testing and maintenance providers.This guidebook includes the study of both national and international transit agencies. It is formatted as a reference guide to provide a user-friendly framework of consolidated guidelines and recommendations that will help in mitigating and/or eliminating stray current leakage from dc operated rail tracks using the data collected from transit agency and corrosion consultant interviews stray current corrosion survey questionnaires and field testing of a mix of 30 transit agencies (21 national and 9 international).This paper discusses “Lessons Learned” on the problems of surveying the transit industry how they were overcome and the results of a case study on issues related to stray current effects from one of the transit agencies that were used in preparing these consolidated guidelines and recommendations.

Stray Current Interference Simulation and Mitigation Associated with Light Rail Transit (LRT) Systems and Adjacent Metallic Pipelines – A Case Study

Product Number: 51323-18926-SG

Author: Boshra Momen Nejad, Jeffrey Delorme, Brandon Miller

Publication Date: 2023

$20.00

During operation of DC rail transit systems, DC current will follow the path of least resistance when returning to the Traction Power Substations (TPSS) to complete the electrical circuit. If the track-to-earth resistance (resistance between the train rails and surrounding soil) is not sufficient, current can leak off the LRT track system into the surrounding soil. Metallic facilities such as pipelines in the soil offer lower resistance paths for the current while returning to the TPSS.
