Detection Leakage of Welds on The Bottom Plate of Oil Storage Tank Vacuum Box Weld Leakage Detection System

Detection Leakage of Welds on The Bottom Plate of Oil Storage Tank Vacuum Box Weld Leakage Detection System

1. Product introduction

In order to improve the overall inspection of oil storage tank, our company has specially designed and developed a series of vacuum tank detection systems for the detection of leakage of welds on the bottom plate of oil storage tank.

The standard, portable vacuum tank detection system can detect the lap/butt weld on the bottom plate of any size of storage tank, and the circumferential weld (fillet weld) on the bottom plate of storage tank with a diameter of more than 5 meters. For the integrity evaluation of various welds, our vacuum box detection system is an efficient, fast and economical detection method, and the detection rate of penetrating corrosion/pinholes is not less than 95%.

2. Special features

1) Normal model generally use the hand to press the box, so it will be very tired, we improved the need to bend over directly with the feet

2) When moving, we have wheels under tank; don't need to lift the tank to move

3) The vacuum pump can take remote control of the robot, the site is very convenient.
