Effect Of Steel Surface Profile Peak Density On Rust Creepage

Product Number: 51322-17584-SG

Author: Russell Draper, Michael Beamish

Publication Date: 2022

$20.00

The spread of disbondment or corrosion from a scribe or holiday in a coating film, for which the terms rust creepage or undercutting are used in this paper is an important mechanism of coating degradation. The mechanism of rust creepage has been well studied by several authors who concur that the mechanism is driven by electrochemical reactions15. The reactions occurring at the discontinuity in the coating (scribe or holiday) involve an anodic reaction in which iron is dissolved. Adjacent to the anodic region, under the coating, a cathodic reaction occurs in which oxygen is reduced to hydroxyl ions.

Effect of Surface Preparation of Coating Performance

Product Number: 41216-953-SG

Author: Devin Clark, Richard C. Ferguson & James W. Rawlins

Publication Date: 2016

$20.00

Coating performance and longevity is highly dependent on the quality of substrate surface preparation. The effect of profile height, profile type (e.g., type of tool used to perform the prep, angularity of profile, etc.), extent of cleanliness, and amount of chloride contamination on coating performance were all studied to determine the correlation between these factors in an attempt to identify the primary factor in coating failure due to improper surface preparation.

Effect Of Temperature On Inhibition Efficiency And Data Analysis With Different Adsorption Isotherms

Product Number: 51322-17895-SG

In the oil and gas industry, long-distance transportation of petroleum and related products is usually carried out in large-diameter carbon steel pipelines. Water present with the oil, along with corrosive species such as CO₂, H₂S and organic acids, causes severe corrosion of the inner pipe walls.¹ An effective method of controlling corrosion is to continuously inject corrosion inhibitors into pipelines conveying oil-water mixtures. As corrosion occurs on water wetted metal surfaces, corrosion inhibitor (CI) molecules form protective films which retard electrochemical reaction rates at the water-metal interface,² thereby protecting carbon steel pipes against CO₂ ("sweet") corrosion and H₂S ("sour") corrosion. Most commercial CIs are a complex mixture of several compounds that contain surfactant-type active ingredients, such as imidazoline, amine, phosphate ester, and quaternary ammonium derivatives.

Effects of Blasting Methods on the Performance of Organic Coatings

Product Number: 41206-267-SG

Author: Andreas W. Momber

Publication Date: 2006

$20.00

The effects of three blasting methods utilised for surface preparation upon the behavior of five organic coating systems are investigated. The blasting methods include dry blast cleaning, UHP and UHPAB. It is shown that pull-off strength, pull-off failure mode, and delamination are significantly affected by the surface preparation method.

Efficacy Of MIL-DTL-5541 Compliant Non-Chromate Conversion Coating Repair Materials

Product Number: 51322-17625-SG

Author: David G. Enos, Derek Wichhart

Publication Date: 2022

$20.00

Chromate conversion coatings are relied upon to ensure the long-term corrosion performance and surface electrical properties of aluminum alloys, as well as to improve the bond strength and adhesive properties of organic coatings and adhesives. Chromate based chemistries have been all but eliminated in Europe, and it is believed the Environmental Protection Agency (EPA) will stage their elimination in the USA within the next 5 to 10 years. The development of chemistries to replace chromate has been a hot area of research for over 30 years, and now a series of commercial alternatives have become available. These new coatings differ in their chemistry and performance characteristics, as well as their functional limitations, from chromate.

Efficient Polyurethane Pipe Coatings for Harsh Conditions

Product Number: 41214-869-SG

Author: Andreas aus der Wieschen, Matthias Wintermantel, Todd Williams, Ahren Olsen

Publication Date: 2014

$20.00

Solvent-free two component polyurethane (2-K-PU) systems have been approved as suitable protective coatings systems since many years. Two component polyurethanes are favored within pipeline and tank constructions where high performance and durability have to be accomplished under harsh conditions (e.g., field application, high service temperatures, high salt load, wet soil conditions etc.).

Precipitation hardened (PH) Ni-based alloys have been utilized in oil and gas industry for decades. Among them, UNS1 N07718 because of its performance in sour wellbore fluids and in hydrogen charging environments has received the most attention for multiple upstream applications such as tubing hangers, production stab, multi-phase flow meter bodies, valve stems, etc. It has been reported that the alloy performance is generally acceptable for many applications up to 175 °C (350 °F) – 204 °C (400 °F) in the exposed wellbore environments such as sour production fluid, completion brine, and depending on metallurgical processing and microstructure externally exposed to SWCP at the seabed temperature.
