Boroscopic testing is a visual inspection test for internal heat exchanger and tube failures using fiber optic and rigid boroscopes, including Photography or videotape. Boroscopic testing reveals damages to internal blades etc. Boroscopes are used for inspection in other applications, also. Anywhere access is difficult is a potential application.

What is first article inspection?
The verb "first article inspection" is the act of comparing a physical sample part with the specifications (usually a detail drawing, or blueprint) against which it was made. The sample is usually one of the first parts made from a tooling or a setup, thus the name. Each specification dimension is measured on the physical part, compared against the print, and a list constructed of which dimensions were met and which weren't. For a simple part, this list is quite small. But for a complex part the list of dimensions can be extremely long and the inspection quite involved. By definition, any dimension that appears on the print must be measured on the part and listed in the report. The noun "first article inspection" is the documentation that results from the activity of the verb form. This may also be referenced as a "First Article Report".
What is a b pressure welder?
This welder is certified to weld on pressure vessels. Testing is done on the weld either by X-Ray or pressure test. The root pass is inspected then the final pass is inspected during the test. If either inspection turns up a flaw, the test is over and you fail.
What is the meaning of HMV in aircraft maintenance check?
This is the most comprehensive check for an airplane. It is also known as a Heavy Maintenance Visit (HMV). This check occurs approximately every 4-5 years. This is the check that, more or less, takes the entire airplane apart for inspection. This requires even more space and time than all other checks, and must be performed at a maintenance base.
How do you find across corner of the hexagonal nut by only using Across flat thickness?
2*((flat dist/2)/0.866) Or in words: Take half the flat distance, divide that by 0.866, multiply the result by 2. You can derive this yourself by drawing a hexagon and drawing in the lines you want through the exact center of the hexagon. You will discover this makes two right triangles, the hypotenuses of which are the "across corners", and the "long sides" of which are the "across flats". By inspection, there are 12 of these triangles, meaning the small angle of each is 30 degrees. The cosine of 30 degrees is 0.866, which is the ratio of each triangle's "long side" to their hypotenuse. Do the math and you will come up with the formula above. Cheers!
What is barring device in compressor?
A barring device in a compressor is a mechanism or system designed to facilitate the manual rotation of the compressor shaft during startup or maintenance activities. Compressors are crucial components in various industries, and they often operate in conjunction with large motors. The barring device allows for the slow and controlled turning of the compressor shaft without the need for energizing the main motor. Key features and purposes of a barring device in a compressor include: Manual Rotation: The primary function of the barring device is to allow operators or maintenance personnel to manually rotate the compressor shaft. This can be necessary during startup procedures, inspections, or maintenance tasks. Reduced Friction: The barring device is typically designed to minimize friction and resistance, enabling smooth and controlled rotation. This is essential to prevent damage to the compressor components and to ensure the safety of personnel. Alignment Checks: During maintenance or inspection, it is often necessary to rotate the shaft to specific positions for alignment checks or to access different sections of the compressor. The barring device facilitates this process. Emergency Situations: In the event of a motor failure or other issues preventing the normal operation of the compressor, the barring device can be crucial for emergency procedures. It allows for controlled manual rotation to address the situation. Shaft Positioning: The device helps position the compressor shaft precisely, allowing for the correct alignment of various components, such as blades, seals, and bearings. Safety Features: Barring devices often incorporate safety features, such as interlocks, to ensure that the compressor is not accidentally started while the barring device is engaged. This helps prevent accidents and damage to the equipment. It's important to note that the design and implementation of barring devices can vary depending on the type and size of the compressor, as well as the specific requirements of the application. Barring devices are commonly found in large compressors used in industries such as petrochemical, refining, power generation, and other heavy industrial settings.
What are the maintenance activties in gas turbine?
Maintenance activities in gas turbines typically include regular inspections, cleaning of compressor blades, monitoring and replacing of filters, checking and replacing lubricants, inspecting combustion chamber for leaks or damage, and performing any necessary repairs or adjustments to ensure optimal performance and efficiency of the turbine. Regular maintenance helps to prevent breakdowns and extend the lifespan of the equipment.
