TuyauterieIndex. décimale : 667.9 Revêtements et enduits Résumé : During the 2000s, the concept of cathodic protection (CP) shielding was first raised in open literature and remains debated between coatings professionals. The mechanism of CP shielding, and its understanding continue to be studied for different coatings with different approaches and using various techniques. From the CP shielding factors to the assessment methods, the published literature merits a deep analysis to capture the established knowledge and identify the research gaps to further tackle the issue for reliable coated buried structures. A holistic approach to this topic seems necessary where coatings ageing, cathodic protection, electrochemistry, and transport processes should be considered. In the first part of the present review, the recent works related to the understanding of CP shielding, coatings properties were considered before discussing the mechanisms involved underneath coatings. Transport phenomena and their relationship with cathodic protection performance in the presence of chemical and microbiological processes are discussed in the second part. Finally, CP shielding assessment methods and modeling works are presented and discussed from different perspectives. Note de contenu : - Cathodic protection shielding

Tuyauterie -- ProtectionIndex. décimale : 667.9 Revêtements et enduits Résumé : Protective coatings for carbon steel are well known as an economical method of controlling corrosion versus the use of alternative materials such as stainless steel. At first glance, buried piping seems to have a stable environment. One might assume that coatings would not necessarily be required, as they might be for atmospheric environments, which are bombarded with rain, snow (depending on location), fog, ultraviolet light and significant temperature differentials. Buried environments, however, even in semi-arid climates, contain enough moisture in the soil to conduct ionic current, which completes the circuit for corrosion of most metals.
One way to control buried corrosion is to employ cathodic protection (CP), and indeed, buried pipe corrosion can be controlled with CP alone. The limitation of using solely CP, however, is the amount of CP required to protect the exposed surface area. The greater the current requirements, the larger and more expansive the CP required, meaning greater installation, maintenance and monitoring costs which drives up the cost of operating a pipeline. And for pipelines carrying hazardous materials, the requirements for maintaining the lines are prescribed by federal law. Therefore, a cost-effective design approach is to use coatings in conjunction with cathodic protection to protect the line.Note de contenu : - Coating system selection

L'acier est constitué d'au moins deux éléments, le fer, très majoritaire, et le carbone, dans des proportions comprises entre 0,02 % et 2 % en masse1.
C'est essentiellement la teneur en carbone qui confère à l'alliage les propriétés du métal qu'on appelle "acier". Il existe d’autres métaux à base de fer qui ne sont pas des aciers comme les fontes et les ferronickels par exemple.

SilanesIndex. décimale : 667.9 Revêtements et enduits Résumé : Fusion bonded epoxy coating, also known as fusion-bond epoxy powder coating and commonly referred to as FBE coating, is an epoxy based powder coating that is widely used to protect various sizes of steel pipes used in pipeline construction, concrete reinforcing re bars and on a wide variety of piping connections, valves etc. from deterioration due to corrosion. Protecting pipeline systems from corrosion is essential to prevent leaks and consequent possible environmental disasters, fire and explosion, personal in jury, service disruption, and costly maintenance. This paper reviews history, chemistry, manufacturing process, surface preparation, application, characteristics for FBE. It is indicated that FBE was introduced as a protective coating early 60's. The coating is applied by manual spraying guns, or fluid-up process, and blast cleaning is the most commonly used method for preparation of steel surfaces. "Induction heating" or "oven heating" are mostly used as heating processes. Advantages of FBE are : ease of application, less waste of material, rapid application, faster production rates compared with the conventional liquid coatings. Note de contenu : - FBE-HISTORY

Revêtement époxy lié par fusionIndex. décimale : 667.9 Revêtements et enduits Résumé : Now a days several field joint coatings are available to complete the coating of a pipeline. Special attention is requiring to have an adequate and full proof coating for the Joints in a main pipeline otherwise, the joint can become the pipeline's weakest link in the mainline and may have some future issues for pipeline integrity. Being applied in field at laying site, the coating must be user friendly to the application environment and easy to be installed correctly. For a successful field joint coating, it is very necessary to include a proper project planning, coating selection and prequalification, surface preparation, applicator training and certification, equipment selection, inspection, and storage and handling.

Il a été isolé en 2004 par Andre Geim, du département de physique de l'université de Manchester, qui a reçu pour cette découverte le prix Nobel de physique en 2010 avec Konstantin Novoselov. Il peut être produit de deux manières : par extraction mécanique du graphite (graphène exfolié) dont la technique a été mise au point en 2004, ou par chauffage d'un cristal de carbure de silicium, qui permet la libération des atomes de silicium (graphène epitaxié).

TitaneIndex. décimale : 667.9 Revêtements et enduits Résumé :
Epoxy coatings have generally been used in applications that require the surfaces to be protected against corrosion. However, their use in demanding applications wherein the contacting surfaces are required to be protected against wear and tear has been limited due to their inferior mechanical and thermal properties. To overcome this challenge, epoxy composite coatings came into being, wherein the epoxy resin is reinforced with different fillers. However, due to the availability of a large variety of fillers, the selection of a suitable filler and the amount to be used in the epoxy resin for the best properties still remains a challenge. Hence, the focus of this research is to compare the performance of five different fillers, viz. carbon nanotubes (CNTs), graphene (GO), alumina (Al2O3), titanium dioxide (TiO2), and ceria (CeO2) in enhancing the mechanical, thermal, and surface properties of epoxy coatings. The five fillers selected covered the spectrum of carbon based, ceramic, and metallic oxide fillers. Different loadings (0.5, 1.5, and 3 wt%) of each of the fillers were used to fabricate fusion-bonded epoxy composite coatings on mild steel coupons using an electrostatic spray gun. The effect of these fillers was evaluated on the hardness, thermal conductivity, and water contact angle of the epoxy composite coatings. It was observed from the results that 0.5 wt% of Al2O3 was found to be the best-performing filler among all the fillers in terms of higher hardness and 3 wt% of Al2O3 was best in terms of thermal conductivity as compared to the pristine epoxy coatings and other epoxy composite coatings.Note de contenu : - EXPERIMENTAL PROCEDURES :
