If you are looking to get a gas and oil assessment, it could be helpful to know what types of inspections are available to you. There are many different types of inspections used, but there are five that are more popular in New York City than the rest. If you are planning on getting a New York City oil and gas inspection, your inspector will likely be using one of these methods.
Visual inspections to check oil and gas are just as it sounds: an inspection where the inspector looks at the components to see if they can tell if anything is not the way it should be. Just because it is simple does not mean it is not effective, as an experienced inspector is likely to detect improper structural installations, welding flaws, corrosion, cracks and other things that may not be immediately noticeable to the untrained eye.
Ultrasonic Techniques, Radiography and Thermography
Ultrasonic techniques use sound waves, which we are not able to hear to find differences in thickness and cracks during an oil and gas checkup. Radiography is also used and is a similar process except it uses x-rays, which are able to pass through structural materials to see things that may be difficult to see otherwise. Thermography is different in that it uses temperature readings to see if the insulation is functioning properly by comparing the temperature of the pipe against the surrounding environment.
This method uses acoustics to locate negative pressure waves. Because these waves are caused by leaks, these waves are indicative of possible leaks in the pipe. This type of non-destructive testing is most useful when negative pressure waves are present, so it is limited in what it can test so it is basically solely used for testing for leaks.
