An Enhanced Prediction Model For Simultaneous Naphthenic Acid And Sulfidic Corrosion Quantification

Product Number: 51322-17901-SG

Author: Winston Robbins, Sridhar Srinivasan, Abbey Wing, Gerrit Buchheim

Publication Date: 2022

$20.00

Sulfur and acidic impurities in crude oils pose serious hot oil corrosion problems in crude distillation units (CDU) and associated vacuum distillation units (VDU), especially with the increase in processing of lowquality, opportunity crudes.^1-4 In the range of 200-400˚C, reactive sulfur compounds cause sulfidation corrosion of ferritic carbon and chrome steels in CDU, VDU, and front ends of downstream units operating at hot oil temperatures.^5-7 Over the same temperature range, naturally occurring carboxylic acids in crudes can be so aggressive that higher alloy, austenitic stainless steels containing >2.5% Mo are required for processing high acid oils.^8-11 Although sulfidation and acid corrosion occur over the same temperature range, they differ in two significant ways. Sulfidation forms an iron sulfide solid that is semiresistant to further corrosion and relatively insensitive to flow velocity. Acids form oil soluble organic salts that can be washed away especially in areas of high turbulence.^12-14

An Innovative Thermoplastic Coating For CUI Applications

Product Number: 51322-18122-SG

Author: Hindrik Harm Broesder

Publication Date: 2022

$20.00

An innovative thermoplastic type of coating material based on pure isobutene homopolymer was investigated to determine whether it would be fit for purpose in CUI services at low and moderate temperatures up to 120 °C. This polymer is commonly called Polyisobutene (PIB) and has a unique set of properties that are beneficial for protecting metallic structures from corrosion. Polyisobutene is a polyolefin with a chemical structure similar to Polyethylene (PE) and Polypropylene (PP). One of the major differences is that PE and PP are solid materials with a high degree of crystallinity, whereas PIB does not have a crystallization or melting temperature. PIB has a glass transition temperature (T_g) below – 60 °C which indicates that the polymer is a liquid above this temperature.

An Introduction To Low Pressure, Ambient Temperature Polyurea Spraying

Product Number: 41211-616-SG

Author: Stephen Hirt

Publication Date: 2011

$20.00

The purpose of this presentation is to introduce you to low-pressure, ambient temperature spraying of polyurea and to discuss the advantages of low-pressure spray equipment. Some of the inherent advantages are equipment cost, ease of use, less over-spray, and equipment mobility. This presentation will be divided into several key areas. We will examine features and benefits, general equipment specifications, capabilities, operation of the system, typical periodic maintenance requirements and examples of available options.

An Organometallic Ester Corrosion Inhibitor for Use in Direct-to-Metal Acrylic Paints

Product Number: 41212-681-SG

Author: John E. Hughes

Publication Date: 2012

$20.00

Traditionally, the light industrial/general maintenance paint systems involved a primer along with multiple coats of acrylic finish paint to achieve acceptable corrosion resistance over mild steel substrates. The new Direct-To-Metal (DTM) acrylic paints are formulated to eliminate the primer and perform as a primer and as a tough finish coat in a single paint, reducing the time and materials needed for complete coverage

An Ounce of Prevention... The Reliability of Field Methods for Detecting the Presence of Amine Blush on Epoxy Coatings

Product Number: 41205-190-SG

Author: Michael Orzechowski

Publication Date: 2005

$20.00

Shop and field conditions of high humidity and cool temperature during curing of amine-cured epoxy coatings can produce a haze or oily residue on the surface. This is commonly referred to as “amine blush.” The residue is caused by the presence of unreacted amine on the surface of the epoxy coating reacting with carbon dioxide and moisture in the air to form a carbamate.

An Overview and Comparison of Surface Cleanliness Standards for the Protective Coatings Industry

Product Number: 41216-965-SG

Author: Nico Frankhuizen

Publication Date: 2016

$20.00

At present multiple standards on blast-cleaned surfaces are in use depending on region and specifications of the project. However, most standards are relatively clear on the description of a surface some overlap each other. These overlaps are often considerate as the norm for the most comparisons between ISO and related documents, however, sometimes are significantly off. Some of these documents will be highlighted to compare the results and their impact on the coating job.

An Overview of Petrographic Examination of Concrete as Related to Polymer Floor Coating Failures

Product Number: 41213-727-SG

Author: Jon Asselanis

Publication Date: 2013

$20.00

Often when a polymer coating failure occurs, the concrete quality and integrity are questioned. Core samples removed from the concrete slab are examined using petrographic techniques to help determine the cause of the coating failure. The basics of the petrographic examination, the equipment used and what information it can provide are presented.

An Update and Review of Offshore Systems and Current Testing Scenarios

Product Number: 41206-266-SG

Author: Mike Mitchell

Publication Date: 2006

$20.00

Offshore coating systems have evolved over the past 50 years to allow for restrictions in raw material use and solvent emissions. This has meant that many tried and tested systems can no longer be used. This paper describes the industry in terms of attempts to generate suitable prequalification testing scenarios which will prevent premature failures of untried new systems

Analysis of Coating Blister Failures and Associated Coating and Substrate Risks

Product Number: 51220-254-SG

Author: Michael Kibler, Patrick Cassidy, Jay Ong

Publication Date: 2020

$20.00

Blistering is a common failure in marine coatings that can be caused by both physical, such as osmotic pressure and temperature gradients, and electrochemical forces like cathodic or anodic polarization. This paper/presentation will start by discussing the various mechanisms that lead to coating blistering, how blisters form, and how to prevent them.
