Fiberglass reinforced plastic (FRP) has properties that, if disregarded, can lead to failure during operation. The same properties, if taken advantage of, can provide the user with performance superior to traditional alloy materials. This paper discusses principles in designing process and facilities piping systems with FRP.
This paper aims to present a novel class of pipeline protective lining materials that provide erosion-corrosion resistance combined with negligible wear to spray equipment. These coatings have been formulated with a blend of thermoplastic fillers rather than the traditional ceramic fillers used for erosion resistance.
Multi-layer polypropylene (MLPP) insulation coating is used for thermal insulation of subsea pipelines. However in recent years - with higher wellhead operating temperatures - high temperature (HT) Fusion Bonded Epoxies have been used. This paper describes the author's experience with the MLPP systems over the last 20 years.
Self-healing coatings for corrosion protection refer to those with the ability to sense the corrosive environment and to release preloaded inhibitors from the coating matrix by a controlled mode. In this work, SiO2 nanoparticle based polyelectrolyte nanocontainers were fabricated by the LbL method to store corrosion inhibitor BTA.
Overview of coatings for a cyclic-temperature environment. Test method, including a heat cycle between 21 to 300 deg-C simulating the dehydrator operation and exposure to salt spray. The performances of the three coatings were evaluated using this method. Factors to be considered for coating selection in the cyclic-temperature environment are discussed.c
Encapsulation of Linseed Oil & Tung Oil in urea-formaldehyde shells was performed using in-situ polymerization technique. Thin film self-healing coatings with uniform and quick self-healing ability were achieved with microcapsules at concentration of 3 wt%. Anti-corrosive performance was evaluated using immersion test & electrochemical impedance spectroscopy (EIS).
Traditional internal lining schemes for the storage/transport of crude oil & refined fuels may no longer be appropriate. The aggressive nature of crude oil (high temp. & more sour), high purity refined products & increased use of biofuels demand better linings & more certain test results. The focus of this paper is to review the trends in test methodology from the early 1990’s to present.
Organic coating systems for protection against internal corrosion of pipelines are important to maintain integrity of oil and gas infrastructure. The present investigation focuses on evaluation of protective properties of a set of multiphase coating systems in the environment encountered inside of off-shore natural gas pipelines.
Development of a new High Charge Polymer (HCP) for cooling water applications. This polymer provides superior deposit control in stressed applications where high temperature, hardness, phosphate, pH and metals contamination can reduce dispersant performance. Reviews lab work. Describes refinery field trial results. Active fouling was mitigated.c
This paper will review the features and benefits of a new epoxy coating technology that allows for true epoxy-amine curing in a single-pack product. Performance versus traditional two-component epoxy products will be compared, and environmental and convenience benefits of single-pack versus two-component packaging will be discussed.
