Eddy Current Tank Floor Inspection

The slofec inspection technique uses the eddy current principle in combination with a magnetic field.

Eddy current tank floor inspection.

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. Pulsed eddy currents pec are perfectly suited to tackle this challenge. Coating thickness up to 10mm. The inspection was conducted at the client s site from the 24th may 20xx and completed on 25th may 20xx.

Pulsed eddy current pec inspection. Pec is an advanced electromagnetic inspection technology used to detect wall loss such as corrosion and tank thinning in ferrous materials. Saturation low frequency eddy current inspection technique for tank floors pipes and vessels key features of the system fast screening method for local metal loss inspection of thick wall components up to 35 mm inspection through thick coating up to 10 mm inspection speeds up to 25 m min higher defect detection sensitivity than mfl. Two types of floor scanners are used to perform the inspection of flat bottom storage tanks.

This probe was developed for the in service inspection of storage tank floor annular rings. The slofec inspection system is based on the eddy current principle with superimposed dc field magnetization. Currently no other inspection technique can do this without emptying tanks. Based on the next generation mec magnetic eddy current technique innospection s capabilities in tank floor inspection with the mec floorscanners are.

This allows detection of corrosion attack metal loss even at the subsurface from the surface side. The task of the inspection system is to detect defects in tank floors walls and roofs as well as in pipe. With its super thin 4 8 mm 0 2 in titanium blade the probe can slide up to 400 mm. The silverwing floormap tank bottom inspection system combines two technologies.

Magnetic flux leakage technique predominantly for the tank floor inspection application. 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. The mec technology works with a. Tank floor pulsed eddy current pec probe tank floor pulsed eddy current pec probe.

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. High sensitivity in detecting corrosion pitting and local defects in tanks with plate thickness up to 30mm.
