...Abstract As the service conditions for non-metallics becomes ever more challenging, their reliability and fitness for service evaluation requires more refined levels of testing. For elastomers used in HPHT sour conditions, the need to evaluate their ability to continue to seal requires testing...

... of various polymeric materials are important. For biodiesels, uniform and localized corrosion of steels is important. This paper will provide an overview of research that has been conducted in alcohol fuels and identify gaps in knowledge. FGE Ethanol SCC Localized corrosion elastomers swelling Since...

..., Resins and Asphaltenes components of the crude oils is shown in Table 1 . Materials EXPERIMENTAL PROCEDURE The objective of this study is to determine the physical and chemical behavior of an elastomer (NBR) used in stator of progressive cavities pumps in contact with different crude oils (A, B, C...

...) of carbon steel pipe and the performance of select elastomer seals/gaskets have been studied (in other projects) in FGE. Although many of the issues related to corrosion of carbon steel pipe in ethanol have been resolved in these projects, to address completely the effect of ethanol and gasoline-ethanol...

...Abstract Biofuels represent an important renewable fuel alternative to petroleum-derived transport fuels. Materials compatibility is a major concern whenever the fuel composition is changed. The aim of this work is to study the interaction of the elastomers: FKM, EPDM, CR, CSM, NBR, IIR, VMQ...

... to be outweighing the need for thoughtful application and inspection in the field. Given this, this paper will examine the shortfalls in many jobs that often go unnoticed by non-existent or unfamiliar inspectors. Coatings and linings Thermo-set elastomers Wastewater treatment coatings inspections concrete...

... thermoplastic material are assessed by swelling, hardness and compression-set measurements. The study indicated that the volumetric swell of all elastomers subjected to ethanol exposure under static load conditions is found to increase as the amount of gasoline in ethanol blends is increased. The swelling...

... they are with hydrocarbon-only fuels. A sampling of recommended elastomers exposure to dilute and concentrated ethanol-gasoline blends is provided in Tables 1 . ⁵ Relative size of the ethanol molecule: Ethanol is a smaller and more polar molecule than many other oxygenates, such as, MTBE and ETBE...

... are similar to that of thick coatings. Linings are sheets of plastics or elastomers applied and adhesively bonded to the substrate. Organic linings are thermoplastics or elastomers with varying corrosion resistances; elastomeric linings often consist of several plies of different materials for degradation...

...Abstract Prior to application of a new inhibitor in oil or gas production, the system compatibility of the new chemical must be confirmed. Based upon an upfront analysis of metals and elastomers encountered in the system, material compatibility tests are performed under system conditions...

... the elastomers by altering their properties such as swelling, shrinking, elongation, hardness, tear-strength and tensile strength. Fully formulated muds along with base fluids were tested for their effect on elastomers. THE COMPLEXITY AND COMPATIBILITY DILEMMA SBMs have been formulated using a variety...

.... The technology for EOR is well established; the proper application and engineering of the particular technology in a given field requires a knowledge of reservoir geology and geography as well as the production layout. INTRODUCTION polymers EOR elastomers explosive decompression miscible injection Abstract...

...Abstract A new test method for the evaluation of chemical resistance in polymers (thermoplastics, thermosets including FRP, and elastomers) is presented, discussed and compared to existing standard test methods. The major advantage of this new multiple observation method is that more reliable...

... elastomers plastics diffusion sorption permeation Fick's Laws INTRODUCTION Non-metallic materials such as plastics and rubbers are widely used as materials of construction in the process industries. Their prevalence results from their ability to withstand some environments better and at lower cost than...

...Permeation of gases through elastomers, driven by high pressures, is of considerable concern to engineers, both for the possible problems raised by permeation itself, and for the related problem of explosive decompression. The aim of this paper is to review the theory of gas diffusion...
