Internal linings used for corrosion protection often have to perform under severely corrosive environments. One major concern regarding coating performance is the negative effect of soluble salts on the steel substrate at the time of lining application, particularly for higher temperature lining applications. These salts impact the ability of the applied coating systems to protect the steel in several ways including osmotic coating blistering, promotion of under-film metallic corrosion and lining disbondment.
Maintaining the integrity of oilfield equipment is essential to its safe operation and to maximize the efficiency of production. The integrity of oilfield equipment can rely on material selection and control of conditions, however, it is commonly maintained by the applications of chemical corrosion inhibitors (CI). Prior to use, these chemicals must be shown to perform as desired under the field conditions in question. To achieve this, chemicals are often evaluated using robust laboratory-based screening studies to identify potential candidates.
The technical objective is to demonstrate low-cost solutions to improve building insulation and energy efficiency through the addition of exterior paint coatings.
Proper surface preparation to create sufficient adhesion of a coating over the substrate is fundamentally important in the long-life performance of a protective coating. Abrasive blast cleaning provides a fast and well-established method of surface preparation, which utilizes energy generated by an air supply to deliver a mass of abrasive particles at certain speeds and volumes to impact the steel resulting in a cleaned surface. The method not only cleans the surface to remove rust, scale, paint, and similar contaminations, but also roughens the surface to produce mechanical and chemical adhesion for a coating. Therefore, abrasive blasting is the preferred method for preparing steel for the application of high-performance coatings and routinely used for achieving the required surface conditions prior to a coating work.
The University of Kentucky’s Kentucky Transportation Center (KTC) is working with the Kentucky Transportation Cabinet (KYTC) and the structural steel coating industry to develop a revolutionary tool to aid in the inspection of protective coatings applied to steel structures.
This paper will look at the evolution of coatings and linings in wastewater treatment and what has changed the way we look at protective coatings for concrete substrates. We will look at the coatings and linings used in the past, those used today, and what will be required in the future. The paper will discuss the advantages and disadvantages of varying coating types and why they are or are not still in use.
Since the dawn of mankind, or at least since the advent of the very first accelerated corrosion cabinet, it has been the goal of coatings evaluators to develop an accelerated corrosion testing protocol which reflects the real world of corrosion in totality. There have been passionate arguments promoting one or another testing protocol while demonizing others, but that one protocol has yet to be developed to everyone’s satisfaction.
A new era of natural gas exploration is spreading across the continental United States and Canada. Through a technique called hydraulic fracturing (fracking), huge deposits of oil shale, like the Marcellus and Utica deposits that extend from the Appalachians and into Canada, are now producing enough gas to meet North America’s needs for the next 14 years. The boom in gas exploration has opened up new markets for pipeline and joint coating materials to provide corrosion protection.
When protective coatings are considered for application work, normal uses such as concrete coating, waterproofing, abrasion protection; steel corrosion protection; and other protective applications are the norm. However, there is a whole world of other uses for protective coatings including personal protection applications. The reality is that coating systems are being used for a variety of government, military, police and personal protection applications with excellent results.
High strength low alloy (HSLA) steels are preferred for oil and gas pipelines due to their outstanding mechanical properties. Sulfide stress cracking (SSC) has been a major problem for the application of HSLA carbon steel because of the wet H2S environment which commonly presents in oil and gas industry. Several techniques are applied to the study of SSC of steels, including constant load test with smooth specimens and DCB testing.
High strength carbon steel tensile wires confined in the annulus of flexible pipes might experience corrosion when the annulus is flooded with water, either due to outer sheath breaches or to condensation of water molecules permeating from the bore through the inner sheath. Carbon dioxide (CO2) molecules may also permeate from the bore and reach the annulus, where it dissolves into water to form carbonic acid (H2CO3).
