Eddy Current Tank Floor Inspection

Pec is an advanced electromagnetic inspection technology used to detect wall loss such as corrosion and tank thinning in ferrous materials.

Eddy current tank floor inspection.

With this system objects with up to 25 mm wall thickness and coating up to 10 mm are testable depending on the scanner type. Pulsed eddy currents pec are perfectly suited to tackle this challenge. High sensitivity in detecting corrosion pitting and local defects in tanks with plate thickness up to 30mm. Based on the next generation mec magnetic eddy current technique innospection s capabilities in tank floor inspection with the mec floorscanners are.

With its super thin 4 8 mm 0 2 in titanium blade the probe can slide up to 400 mm. Pulsed eddy current pec inspection. This probe was developed for the in service inspection of storage tank floor annular rings. Easy to use shielded pulsed eddy current solution reaching under tank floor edges to scan for corrosion.

The silverwing floormap tank bottom inspection system combines two technologies. This allows detection of corrosion attack metal loss even at the subsurface from the surface side. The mec technology works with a. The slofec inspection system is based on the eddy current principle with superimposed dc field magnetization.

Tank floor pulsed eddy current pec probe tank floor pulsed eddy current pec probe. Magnetic flux leakage mfl and surface topology air gap reluctance sensors stars featuring top and bottom plate corrosion views and capable of going as fast as 1 m s 3 2 ft s floormap improves the complete tank inspection process. Client a mec tank floor report page 2 of 12 tank c final inspection report k0xx 16x executive summary innospection ltd was requested by client a to perform a magnetic eddy current mec inspection on the floor plates of tank c. Two types of floor scanners are used to perform the inspection of flat bottom storage tanks.

The inspection was conducted at the client s site from the 24th may 20xx and completed on 25th may 20xx. Currently no other inspection technique can do this without emptying tanks. The slofec inspection technique uses the eddy current principle in combination with a magnetic field. The task of the inspection system is to detect defects in tank floors walls and roofs as well as in pipe.

With a combination of highly skilled personnel and a robotic tank floor inspection system techcorr provides api 653 compliant inspections of above ground storage tanks without the risk cost or hassle of removing tanks from service. Principle of mec technique the mec magnetic eddy current technique is the next generation and a further development of the slofec saturation low frequency eddy current technique.
