Is pipeline trachoma pipeline corrosion? What should be noted?
It depends on the usage environment and the shape of the sand hole to determine.
There are many causes of trachoma, such as material corrosion, inappropriate selection of the base material, inappropriate choice of welding materials, substandard processing conditions, excessive temperature and pressure, etc. The specific cause depends on the location and symptoms of the corrosion. Check each one individually
It depends on the specific situation; it could be caused by corrosion, or it might be a defect in the material itself!
From the perspective of my previous work in installation and construction, sandhole defects depend on their location: they are usually caused by manufacturing defects in the base material, while those on the weld seams are due to welding quality issues. Considering the current focus on inspection and maintenance, if the affected area is in an environment with high corrosion and erosion levels, sand eyes can also form.
