Under the vacuum conditions, key surface materials may evaporate, rendering them difficult to detect. A typical working space is 5 by 5 by 5 cm. This restricts the size of the item to the size of the vacuum chamber. Limiting factors that must be considered when using SEM /EDS are: These secondary electrons are detected and create a black-and-white image with varying intensity, just like a common black-and-white photograph. The intensity of the escaping electrons depends mainly on the atomic mass of the surface and somewhat on their crystal orientation. The beam, focused by electrical lenses and scanned over the surface of the substrate, generates secondary electrons that escape from the surface. How an SEM WorksДЄn SEM uses a vacuum in which high voltage generates an electron beam. Compared to iron, iron oxide is more noble, resulting in solution of the iron in the water phase. Common noble elements present on the steel surface are carbon and scale (which is iron oxide). The presence of more noble (inert, or nonreacting) particles or sections on the surface create galvanic action. Just as steel structures have unique names such as pearlite, bainite, and martensite, these hydrated structures have specific names, such as goethite, esmeraldite, limonite, and turgite.

In the tube and pipe industry, almost all of the corrosion is in the form of iron hydroxide, which is iron oxide with bound-in water (usually red-brown to yellowish in appearance). Corrosion exists in many forms such as rust, commonly but mistakenly known as iron oxide (which is mostly black in appearance). Many factors influence the reaction speed, including pH, oxygen, concentration, complexing chemistry, and solubility. Generally, corrosion results from an electrochemical reaction. The following provides a limited explanation of how SEM/EDS works and discusses its possibilities and limitations for microstructural analysis. To help study corrosion issues and pinpoint the causes, Quaker invested in a scanning electron microscope (SEM) and energy dispersive (X-ray) spectroscopy (EDS/EDX) equipment. A lab can provide quick results from simple corrosion tests.

Analyzing the process fluids to verify that they are in good condition and free of bacteria is a practical first step in addressing this issue. This puts the pipe producer at risk for significant financial losses. Pipe corrosion sometimes goes unnoticed until after the bundle has been opened by the end user, which can happen several weeks after pipe production. Furthermore, tube mills often are located in humid or corrosive environments, leaving the newly manufactured pipe vulnerable to corrosion. One key performance indicator of a MWF is corrosion protection because most tubular goods are made from unprotected hot- or cold-rolled steel, which can corrode readily depending on the alloy and end application. In this case, the fluid has to provide good corrosion protection at low concentrations as well as remain free from biological contamination.

The hydrotesting stage requires the MWF to perform a different set of functions, normally described as the secondary role.

Research has proven that more than a 30 percent reduction in tool wear is possible, resulting in substantial cost savings. During pipe end threading, the correct MWF can significantly reduce tool wear. The primary functions of these fluids are to cool, lubricate, and help remove fines from the working area.Дuring the forming process, the fluids are vital to ensure that the pipe surface remains clean and blemish-free, and that the rolls are well-lubricated for long roll life. This characteristic is easy to see, even atДЇorming, threading, and hydrotesting tubular goods require the use of metalworking fluids (MWF), which are usually in the form of water-soluble concentrates that contain mineral oil, synthetic oils, polymers, or a mix of all three. Etching follows the grain borders of the ironД¬rystals where, under some conditions, localized
