The Need For PMI Testing Service

By Harold Young


In many industries, especially in construction and chemical, different alloys are created and utilized for many purposes. In order to examine the chemical components of an alloy, it undergoes a process called Positive Material Identification or PMI. A PMI testing service can assess the durability, standard, and safety of an alloy that has just been manufactured.

PMI inspection services help maintain quality control and safety measures for all business in the industry. They can help determine the temperature tolerance, chemical and mechanical properties, as well as the corrosion resistance of an alloy. These services can help supply industries with metals that will be used in a range of processes.

Certain metals are more appropriate for specific applications in handling, manufacturing, and distributing various products. Alloys that did not undergo testing may pose potential hazards to factory and company workers. Untested metals that have been packaged and furnished for distribution may even turn out to be chemically unsafe. Tons of expenses can be wasted on parts that turn out to be faulty or physically harmful.

Through the identification process, the chemical components of a material are broken down with nondestructive means. A handheld device called the XRF or x ray fluorescence analyzer provides accurate breakdowns of metal samples. The portable unit expedites swift verification and analysis of materials.

Elements commonly identified include titanium, chromium, zinc, cobalt, copper, nickel, iron, and more. By going through a verification process, experts can give their certificate of approval on whether or not some alloys are good for shipping or must be returned to the lab. Large metals are commonly used in major operations in chemical plants and petroleum refineries.

Toxic chemical leaks or work related injuries from faulty machines comprise the long list of consequences of untested equipment. Worse, casualties may even be incurred. PMI testing is critical for all industries because it closely scrutinizes the safety and efficiency of any equipment. Moreover, the testing of scraps can be accomplished in just five seconds.

Moreover, the XRF or handheld device used to analyze components is very easy to use and can be mastered by skilled workers in just a matter of hours. The requirement for PMI first emerged from the need to enhance safety protocols in the oil and gas industry. The increased safety measures were set in place to eliminate the hazards that were inherently present due to the nature of the job.

The nondestructive testing device does not alter the material in any way. This enabled workers to ensure that any defect noted in the equipment was already present even before the PMI testing commenced. This shifts the blame to the responsible party that needs to make the necessary changes to maintain the quality and standard of the metals.

Currently, there are over eighty metals available at our disposal plus more elements are being uncovered. This emphasizes the increasing necessity for PMI testing to allow buyers and suppliers to choose the right elements for specific applications. This also forces companies to make better decisions about the equipment they use and manufacture. They will also be spared from costly lawsuits and expenses in damages and repairs.
