Pipeline endoscope inspection standards
May 10, 2024| Pipeline endoscope inspection standards
The standards for pipeline endoscope inspection mainly include the following aspects:
Determine the inspection site: First, you need to determine the location of the pipe to be inspected, as well as the pressure and temperature inside the pipe, in order to determine the type and size of the pipe endoscope required.
Prepare inspection tools: Secondly, prepare the borescope and determine its length and type, such as optical borescope, camera borescope, etc.
Install the pipe endoscope: Then, according to the size of the pipe, use professional installation tools, such as pipe clamps, pipe pressure gauges, pipe thermometers, etc., to install the pipe endoscope.
Detect the internal condition of the pipeline: Finally, start to detect the internal condition of the pipeline, use an optical borescope or camera borescope to observe the internal conditions of the pipeline, such as defects, corrosion, blockage, etc.
In addition, there are some specific testing standards, such as:
1. Pipe diameter and length: The pipe diameter is greater than or equal to 100mm, and the length is greater than 1000mm.
2. Pipe material: including metal and non-metal.
3. Pipe wall thickness: not less than 1cm.
4. Detect defects: Observe defects such as bulges, pits, welding leaks, excess materials, corrosion and cracks inside the pipe through beam irradiation.
The above standards cover the entire process from inspection preparation to defect judgment, ensuring the accuracy of pipeline endoscope inspection.
