Combatting Localized Galvanic Corrosion at Bolted Connections in Gravity Sludge Thickeners and Clarifiers in Wastewater Treatment Plants

Product Number: 51220-275-SG

Author: R. A. Nixon

Publication Date: 2020

$20.00

This paper will describe this commonplace corrosion problem associated with protective coating damage at dissimilar metal bolted connections and present a typical case history. The paper will go on to explain why slotted bolt holes are more susceptible to more aggressive corrosion damage than round bolt holes. In addition, the paper will present successful measures that can be taken to prevent this prevalent problem.

Compating Corrosion of Nuts & Bolts (Support Rods & Fasteners)

Product Number: 51220-244-SG

Author: John Glass, Edwin Welles

Publication Date: 2020

$20.00

The presentation will discuss the challenges, overall objective and unique characteristics of the viscous-elastic semi-solid compound and bolt cap protection system. Testing, installation procedures and previous projects will be covered. One of the projects to be covered is the system used to protect the support rods of the recently constructed San Francisco Bay Bridge connecting Oakland to San Francisco. The bridge made the news prior to opening when it was determined that a portion of the support rods were experiencing fatigue and showing signs of premature failure.

Complicated Siphon Rehab Challenges Pre-Job Planning Process

Product Number: 51220-288-SG

Author: Greg Smith

Publication Date: 2020

$20.00

The Jim Creek siphon is located in the Arapahoe National Forest in Winter Park, Colorado, elevation 9,000 feet. The siphon was constructed as part of the original Moffat Collection System in approximately 1935/1936, commencing operation in 1937. It is a 54-inch diameter steel pipeline that conveys Fraser River water from the Fraser Canal on the south side of the Jim Creek valley to the Jim Creek-Fraser Creek Canal on the north side of Jim Creek valley. The Jim Creek valley floor includes a significant wetlands complex with sensitive terraced beaver ponds, which require protection during any rehabilitation work.

Corrosion Resistance Comparison of Direct-to-Metal, Weaterable Protective Coatings

Product Number: 51220-281-SG

Author: Mary Roley, Steve Liebhart

Publication Date: 2020

$20.00

An important segment of the high-performance protective coatings market is weatherable, direct-to-metal coatings. Coatings that weather well and provide corrosion protection are recommended for direct-to-metal applications, due to the dual benefits of ease of application and good asset protection. However, performance can vary widely based on the coating type and substrate preparation, with performance often rated by accelerated corrosion testing.

Determining When to Coating Concrete

Product Number: 51220-268-SG

Author: Manuel Najar

Publication Date: 2020

$20.00

Reinforced concrete is the most common building material in water and wastewater treatment facilities. It is very common to see unprotected concrete in severely corrosive environments or corroding reinforcing steel that has been exposed due to construction defects or coating failures. The decision to coat new and existing concrete structures can be very difficult for owners due to the cost, turn-around times for putting structures back into service, and lack of confidence in certain protective coatings.

Developments in Polyamide Rheology Modifiers for Very High Solids and 100% Solids Industrial, Protective and Marine Coatings

Product Number: 51220-267-SG

Author: Yannick Nabil-Moreau

Publication Date: 2020

$20.00

Formulators of these coatings need to address the legislations strongly pushing toward lower VOC content. All around the World, Governments, Paint Manufacturers and Applicators are still discussing viable options, though there is no doubt that challenges related to higher solids content in coating formulations will continue to increase.

Diagnostic of Antifouling Coating Durability after Exposure in Natural Waters by Electrochemical Impedance Spectroscopy

Product Number: 51220-272-SG

Author: Samanbar Permeh, Kingsley Lau, Mayren Echeverria Boan, Matthew Duncan

Publication Date: 2020

$20.00

Coatings are applied to steel elements exposed in natural waters to mitigate the deleterious effects of naturally occurring physical-, chemical-, and biodegradation processes. Degradation of steel submerged in natural waters can occur due to corrosion and marine fouling. Recent findings indicated that there are synergistic effects of surface fouling to facilitate biocorrosion.

Doing It Differently: The Impact of Off-Site Intumescent Coating Application

Product Number: 51220-292-SG

Author: Paul Trautmann, Greg Hansen

Publication Date: 2020

$20.00

The use of passive intumescent fireproofing solutions to meet life & safety goals for commercial structures continues to grow in number annually. More often facility owners are required to incorporate fire proofing protection for up to three hours in order to assure the safe departure of individuals inside the given building in the event of an emergency.

Down-the-Hole Withhout a Paddle: Corrosion Mitigation of Wellhead Surface Casings Using IMM Coatings

Product Number: 51220-241-SG

Author: Nicole de Varennes, Norm Spence, Mike O’Donoghue, Vijay Datta

Publication Date: 2020

$20.00

This paper outlines the aggressive service conditions experienced by wellhead casings and the resulting failures seen to date in the Alberta oil patch. Deleterious in-service conditions include; high temperatures and significant temperature fluctuations, expansion and contraction of the steel substrate, and the wet and dry oxidizing micro-environment, the influence of concrete, and a plethora of chlorides and other contaminants elevating the corrosion rate. Previous corrosion mitigation programs and current inspection techniques are reviewed.

Effect of Surface Conditioning on Corrosion Resistance Using New Vs. Traditional Abrasive Blasting Media Types

Product Number: 51220-291-SG

Author: Wesley S. Towle, Paul W. Rehrig, Ed R. Reitz, Rafi M. Herskovits

Publication Date: 2020

$20.00

Surface conditioning is the first step in building efficient corrosion protection on a part or structure. Key concerns during this step include, how to create a stronger anchor-profile and how to efficiently remove previously coated, damaged, or corroded elements from a materials surface prior to coating. The ideal solution must consider three areas of the surface conditioning process: finish quality, cleaning efficiency and total cost.
