Carbon steel storage tanks are commonly used storage equipment in the industrial field, and regular testing is very important. The inspection covers many aspects, and visual inspection is the basis. Check whether the tank is deformed, corroded, cracked, etc., with special attention to the weld area, as stress concentration at the weld is prone to lead to cracking. The ultrasonic thickness gauge can accurately measure the thickness of the tank wall and determine whether the structural strength is affected by corrosion thinning. Magnetic particle inspection can detect tiny defects on the surface and near the surface, such as pores, slag inclusions, etc. For storage of corrosive mediacarbon steel storage tank, the integrity of the internal anti-corrosion layer also needs to be inspected.

       In addition, pressure testing is indispensable, and the sealing and pressure-bearing capacity of carbon steel storage tanks are tested through water filling or air pressure testing. The detection frequency depends on the usage environment and medium characteristics. The frequency should be increased under severe working conditions. The inspection team uses instruments and combines rich experience to completely evaluate the condition of the equipment, promptly discover hidden dangers and repair them, ensuring its safe and stable operation, extending its service life, and providing good protection for industrial production.
