...Introduction to Mass-Loss Testing. There are several methods for determining corrosion rates (CRs) and to quantitate corrosion damage in a large range of industries. The datum required frequently is the loss of mass (a.k.a. weight loss) of a part or a whole unit over a specific time period...

...This chapter describes various test methods for determining the corrosion rates and types of corrosion observed in fluids that may transit well tubing/components, piping, and facilities of the O&G production and delivery systems. These methods are used to determine rates and manifestations...

...How Do They Relate to Actual Service Life? The relationship between controlled laboratory testing of protective coatings and the performance of those coatings and/or coating systems in actual service is highly controversial. One thing is sure: there has never been a controlled laboratory test...

...This chapter is divided into two sections. The first follows the application process in an FBE plant and describes quality assurance (QA) observations and measurements at each of the steps. ¹ The second summarizes test procedures used either during the coating process or on ring samples...

ASTM D 257-93 “DC Resistance or Conductance of Insulating Materials” (1993). ASTM D 522-93a (latest revision) “Standard Test Methods for Mandrel...

...MIC = Microbiology + Corrosion In this introduction, a few simple rules are presented for consideration before we dive into microbiological test methods. Please be sure to read this section and memorize the “MIC rules.” Since MIC is defined as corrosion affected by the presence and/or activity...

Reprinted with permission, copyright ASTM. TYPICAL CATHODIC...

...Introduction Metals and their alloys are used in a multitude of changing conditions, and corrosion failures are common. The limited predictability of metal performance is the main reason why corrosion tests and corrosion monitoring programs are so important. When properly conducted, these tests...

...Introduction Testing a coating system to determine how it will perform in a certain environment is a critical part of coating selection. Many industry standards exist for testing coatings. NACE International has many well-written standards that are a good start. The International Organization...

...INTRODUCTION The purpose of diagnostic testing (DT) is to outline a process to test for deficiencies in a cathodic protection (CP) system, to identify the cause(s) of such deficiencies, and to determine the requirements to enhance the level of CP to the structure. In an existing CP system, the DT...

... will vary, depending on the test selected: Voltmeter capable of measuring 400 V_AC Copper-copper sulfate reference electrode or reference ground rod Test wires as necessary for the applicable test AC clamp-on ammeter Small hand tools with insulated handles SAFETY EQUIPMENT Standard...

.... This research looks at the electrochemical polarization behavior of AM fabricated UNS R56401 (Ti6Al4V) and NiTi (Nitinol) in a biological fluid. Different build orientations were evaluated as well as different post processing and different surface roughness. Cyclic polarization testing was performed per ASTM...

...The introduction provided a quick overview for testing to be conducted to characterize any samples of gas, liquids, or solids collected from pipelines or process equipment. The initial field tests (those conducted onsite), identify potential hazards onsite, which would necessitate additional...

...Laboratory Tests to Evaluate the Erosion Corrosion Resistance of Copper Alloys When examining laboratory erosion corrosion data, it is often difficult to compare results from different test methods, employing different velocities. This appendix briefly summarizes the most commonly used test...

...The three acceptable methodologies for demonstrating the integrity of pipelines are (a) hydrostatic pressure tests, (b) in-line inspections, and (c) the NACE Direct Assessment methodologies. The pipeline owner/operator selects the methodology or methodologies for use on individual pipelines...
