Thermal Insulating Coatings are a relatively young technology but are gaining worldwide acceptance quickly due to their energy retention capabilities, easy application, ability to protect substrates, reducing maintenance and personnel protection costs. Not to be confused with reflective roof coatings, TICs use all 5 thermal dynamic blocking agents (or principles) to reduce thermal transfer between environments.

Thermally Sprayed Coatings for Corrosion Protection of Offshore Structures Operating in Submerged and Splash Zone Conditions

Corrosion protection of large structures such us wind turbines or offshore platforms operating in corrosive seawater environment is usually provided by cathodic protection (CP) and/or protective coatings. However those methods have some limitations. Organic coatings without CP can provide protection to steel substrate only when they remain intact whereas sacrificial anodes can considerably increase the overall mass of the protected structure and have to be replaced periodically. Moreover sacrificial anodes are only effective under submerged conditions and don’t protect the structure under alternating wetting and drying condition so-called “splash zone” which is particularly corrosive environment due to constant splashing of highly aerated seawater UV radiation and increased concentration of seawater constituents during drying. Furthermore confined volume of electrolyte easy access to oxygen and atmospheric pollutant deposited on the metals’ surface lead to more severe corrosion in this region than in the submerged zone.An alternative corrosion mitigation method is application of thermally sprayed metallic coatings such as thermally sprayed aluminium (TSA). TSA affords long-term and maintenance-free protection to steel substrate in two ways. Firstly when intact it acts as a barrier to the corrosive environment and secondly it provides sacrificial protection by working as an evenly distributed anode which preserves steel in case of a damage of a coating. Moreover large operating temperature range high resistance to mechanical damage and low corrosion rate in ocean water make it a perfect corrosion prevention method for offshore applications.One of the characteristic features of thermally sprayed coatings is porosity which is filled with corrosion products when the corrosion progresses. To delay the self-corrosion of the protective coating application of sealers is recommended.In this work the behaviour of several arc-sprayed metal coatings is investigated under full artificial seawater (ASTM D1141) immersion and compared with simulated splash zone conditions under droplets of artificial seawater. Effectiveness of TSA coatings is evaluated using electrochemical techniques and corrosion products are examined. The effect of novel sealers containing nanomaterials is also assessed.

Thickness Does Matter - The Use of Thick Linings In Industrial Applications

Product Number: 41205-186-SG

Publication Date: 2005

$20.00

While a coating is typically measured in mils, a lining typically refers to an application of 1/16 inch or thicker. Certain industrial applications are best served through the use of a thick lining with unique physical properties that provide superior resistance against abrasion, impact, chemicals, and corrosion.

Thiourea Derivatives As Steel Corrosion Inhibitors: Density Functional Theory and Experimental Studies

Product Number: 51319-13317-SG

Author: Venkata Muralidhar K

Publication Date: 2019

Thiourea and its derivatives have been studied for several decades for their corrosion inhibition characteristics with steels. However their interaction mechanisms with steel are not well understood. Such an understanding may be vital for design of novel thiourea derivatives as corrosion inhibitors for steels. We have carried out state-of-the-art density functional theory (DFT) computations and experiments (weightloss polarization and electrochemical impedance) to understand the effect of thioureas on corrosion of steel. The interactions of several thiourea derivatives viz. thiourea dibutyl thiourea acetyl thiourea diphenyl thiourea tetramethyl thiourea and ethylene thiourea have been investigated. DFT indicates strong interactions between Fe atoms of the surface and C S - atoms of the molecule while the N-atoms do not show any significant proclivity towards interactions with the Fe-surface. Among the hollow on-top and bridge sites on the Fe-surface S-atom was found to preferentially occupy the bridge site which facilitates formation of two strong Fe-S bonds which possibly explains the strong corrosion inhibition by thioureas on steels. Besides DFT computations provided insights for design of much more promising molecules for corrosion inhibition. Experimentally dibutyl thiourea was found to have an extraordinary inhibition effect for steel in 1N HCl in accordance with DFT computations.Keywords: Corrosion inhibitors thiourea derivatives DFT experiments

Time of Flight Diffraction and Modal Analysis of a Butt-welded Pipe

Pipeline and piping have been widely used for decades in the transportation of enormous kinds
of fluids in diverse industries (e.g. oil and gas, chemical and power industries). During the
construction phase of these pipelines, different sizes of pipes (ranging from 2" to 48" or more),
elbows and piping are welded to meet the required design criteria and mechanical properties.
With these in mind, a lot of factors must meticulously be considered to ensure that the finished
weld is suitable for use in all ramifications. This is done in accordance to set down codes and
standards to avoid the possibility of failure. Even though there has been destructive analysis
carried out on the welded joint to ascertain the required minimum mechanical properties, however
scanty numerical and non-destructive analyses are usually performed in line with the established
standards. Therefore, this paper focused on the numerical (modal analysis using ANSYS R15.0
explicit dynamic modeler) and non-destructive (TOFD: time of flight diffraction) analysis on a 4”
butt welded pipe.
The result from the numerical analysis clearly showed the effects of the discontinuities on the
welded joint where discontinuities exist as equally confirmed by the non-destructive inspection.
These parts exhibited higher stress concentration as compared to other parts that do not have
any form of discontinuities and this relates to the fact that the presence of these discontinuities
will accelerate the failure of the welded joint even though the applied stress at those points is
much lower than the yield strength of the material.
