An emerging market driver in industrial water treatment is the move to more sustainable chemistries. Corporate sustainability goals are becoming more common and more stringent. Customers are turning to water treatment companies for innovative solutions that can satisfy their sustainability goals and not sacrifice performance or asset integrity. Indeed, a major trend in evaporative open cooling water treatment is to move away from heavy metals such as zinc and other environmentally questionable materials such as phosphates. Another area of cooling water that is in need of a sustainability refresh is closed cooling loops. The most widespread closed cooling treatment programs are based on combinations of nitrite, molybdate, and borate. All three of these chemicals have regulatory, discharge and/or SH&E concerns.

Coating Failures By Design

Product Number: 51322-18164-SG

Author: Leonard Phelps, Ralf Leistikow

Publication Date: 2022

$20.00

Although the form and function of a well-designed building are important, it is the long-term performance and durability of a building and its components that will be important to the owner(s) and occupants. Therefore, during the design of buildings, the selection of the appropriate materials and understanding the long-term performance of the specified materials exposed to various site-specific environmental conditions is critical in avoiding the potential “failure by design”. The case study presented will focus on the coating failure by design, that could have been avoided by the original design and construction team and resulted in costly litigation and eventually the complete removal of a key architectural element on two high-rise condominium buildings located along the Florida coastline

Geothermal Energy is currently engineered as an “always on” baseload supply, due to the limited flexibility to throttle the well without scaling and fatigue issues, and it is engineered for maximal efficiency at this output level. Scaling is a major problem in geothermal plants, particularly in cases where the geothermal fluid composition and plant operation make it difficult to control scaling. In such areas, particularly where scale inhibitors cannot be employed, the formation of scales can make the process less efficient and in extreme cases can lead to unexpected shutdown.

Cobalt/Chromium Carbide Composite Coatings Applied By Brush Plating For Use As An Alternative To Hard Chrome

Product Number: 51322-18228-SG

Author: Joshua D. Thomas, Danijela Milosevic-Popovich

Publication Date: 2022

$20.00

In the war on corrosion and wear, maintenance repair engineers will be hard pressed to find a plating material as strong as chrome. It has high hardness, high lubricity, low wear resistance, and maintains some of its hardness even after being exposed to high temperatures. However, there’s increasing pressure to find an alternative to this material due to the worker safety and environmental issues it presents. Regularly, hard chrome is electroplated where it is needed using a plating solution containing chromium trioxide. Chromium trioxide is registered with both REACH⁽¹⁾ and the EPA⁽²⁾ as carcinogenic, mutagenic, and teratogenic.

Environmentally Assisted Cracking (EAC) of gas transmission lines constitute about 2.6% of the total number of significant incidents recorded in the U.S. Pipeline and Hazardous Materials Administration (PHMSA) database [1]. For the hydrocarbon liquid pipelines, the EAC-related incidents constitute about 1%. Although Stress Corrosion Cracking (SCC) incidents are a relatively small percentage of significant incidents, it is important to predict the location and rate of growth of SCC because of the potential for catastrophic consequences from the growth of undetected cracks.

Corrosion protection of infrastructure and assets is an area of increasing focus due to increasing financial and safety concerns. On a global scale, corrosion has an annual cost of $2.5 trillion (USD).¹ To combat the deleterious effects of this natural phenomenon, specifiers and owners have many choices in terms of materials and protective coatings. Consideration of both initial and life cycle costs has become more important in the age of increased competition and shrinking maintenance budgets.

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 Atmospheric Corrosion Of Silver Across Multiple Locations

Product Number: 51322-17621-SG

Author: Douglas C Hansen, Ronald Zeszut, David Rubino

Publication Date: 2022

$20.00

Atmospheric corrosion of bare metals is a constantly occurring process that can cause significant damage to metal components and structures. For this reason, it has been extensively studied, especially for steel and aluminum alloys.^1-8 Environmental exposure testing is a common method for studying and characterizing the corrosion severity of a location, which allows for comparison with other regions. Much of this data collection is directed toward development of predictive models for corrosion processes, with the goal of estimating corrosion damage based on environmental conditions.

Publication Date: 2022

$20.00

Using supercritical CO₂ (sCO₂) as a working fluid is being explored for a number of power generation technologies including fossil, nuclear, geothermal, concentrating solar power (CSP) and waste heat recovery^1-7. The various sCO₂ cycles are attractive because of the low critical point (31°C/73.8 bar) and the reduced work of compression compared to an ideal gas. While CO₂ is sometimes described as inert, there is a long history of component degradation in subcritical and supercritical CO₂ and a particular concern about internal carburization^8-16.

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.

Comprehensive Laboratory Analysis Of AC Coupon Test Stations

Product Number: 51322-18151-SG

Author: Mehrooz Zamanzadeh, Martin Latona, George Bayer, Anil Kumar Chikkam

Publication Date: 2022

$20.00

Several alternating current (AC) coupon test stations (CTS) located near AC power lines were investigated to assess the AC interference corrosion risk of the test coupons. Asstation consisted of two ½ inch (1.27 cm) diameter and 1received each AC test inch (2.54 cm) long carbon steel (CS ) coupons. Coupons are much larger than 1 cm ² and current density measurements are not 100% relatable to the SP21424 or ISO 18086 criteria, since these refer to measurements on (typically) 1 cm² . The current densities measured on the coupons in this study will underestimate the AC corrosion threat.
