Description

MAIN ADVANTAGES OF EQUIPMENT

The Equipment provides demagnetization of the pipes along the length, including pipe end areas up to the level 10 .. 25 Gs (Gauss);
The Equipment provides the automatic measurement of the initial magnetization (at the input to the demagnetization device) and the residual magnetism at the output of the demagnetization device;
Auto selection of demagnetization mode, depending on the initial magnetization of the pipe;
The forming of the demagnetization protocol and residual magnetism schedules along the pipe length with the ability to save the results, store and transmit such data in the information network of the upper level.

MAIN ADVANTAGES OF EQUIPMENT

Demagnetization object seamless and welded pipes

Diameter 203 – 630 mm
Wall thickness up to 30 mm
Transportation speed of pipe up to 1 m/s
Residual magnetism level after demagnetization 10...15 Gs (1,0…1,5 mT) (depends on magnetic properties metal)

QUALITY ASSESSMENT

Demagnetization is carries out up to the residual magnetism level according to the following standards: GOSTR 52079, GOSTR 53366, API 5L, API 5CT, DNV-OS-F101, ISO3183, ShellTechnicalSpec, ExxonMobil and analogues to them.
