non-permanent Russia

...This magnetic system is specially designed for non-destructive testing of pumped vacuum devices, that required the creation of a uniform magnetic field not only in the center of the operating bore, but in the toroidal region of large size. The system is assembled on the basis of NdFeB permanent magnets. Field direction:axial Field uniformity in a specified toroidal area:up to ±2% Magnetic flux density (for existing modifications):from 0.1 to 0.4 T Bore diameter:120 mm and more...

...-metallic, underground, ground, aboveground and underwater versions, with a diameter of 50 to 1200 mm with a maximum internal working pressure of up to 20 Mpa (200 Bar) for pumping gas, oil, petroleum products and other gaseous and liquid media, operated at temperatures from minus 60°C to plus 180°C. Fittings are used for permanent (major) repairs of through and part-through flaws of pipelines with a...

...smooth operation, long service life and high maintainability. A sub-type of horizontal pumping units are high-temperature pumps Temperature of the pumped fluid: -50°C to +420°C; viscosity up to 26 cSt; density 2,000 kg/m3 maximum; mass concentration of solid non-abrasive inclusions up to 0.2%; size 0.2 mm maximum Permanent magnets (SmCo) with an operating temperature of up to 450°C are used for operation in these temperature conditions. The pump, a part of the pumping unit, is a single-stage or multi-stage horizontal centrifugal section-type...
