GENERAL PURPOSE MAGNETIC
SYSTEMS
MMT Company has developed and started to produce
a series of novel structures for application in general purpose
devices in many branches of industry.
1. Powerful magnetic systems (see Figure 1) for in-tube
high resolution defectosopes for non-destructive diagnostics of
the pipelines (for transport of gas, oil, and water). These systems
are based on the principle of magnetic flux escape. Powerful magnetic
systems for pipeline scrapers for removal of ferromagnetic build-up
(Figure 2). The scrapers are mounted behind the defectoscope
on the same carriage.

2. Magnetic systems for catcher mill with magnetic catcher.
This device is used for the removal of ferromagnetic debris from
holes and wells during their reactivation, maintenance and new hole
drilling. The fragments of the drilling instruments can be removed
as well.

3.
Magnetic system with magnetic field strength 1.2 Tesla
for the homogeneity control of small modifying admixtures
in sintered metallic compounds.
|
4. Multipole magnetic
lenses for the fundamental experiments in physics.
|
|
|
|
|
5.
Magnetic system module for a vortex-current brake. Braking
force is 350 kg on a combined rail with thickness 20 mm
at relative velocity V = 1m/sec.
|
6.
Magnetic binding clamp for details of shuttering in production
of non-standard ferroconcrete items. Pullout force from
a steel plate is 1500 kg.
|
|
|
|
|
7. Indicator
of ferromagnetic inclusions in non-magnetic materials (e.g.,
steel scrape in a bunch of aluminium chip scrape etc.).
|
8. Magnetic clamps
(a set of 4) for fixation of various materials on ferromagnetic
surfaces. Release force of a single clamp is at least 15 kg.
