Magnetic Tubes

Build or modify your own magnetic separation equipment with Alpha Magnetics' range of Magnetic Tubes.

Magnetic Tubes, sometimes known as Magnetic Cartridges or Magnetic Bars, can remove unwanted ferrous material and contamination from dry particle products, liquids or slurries. By mounting within your existing equipment, either individually or in multiple-row arrays, tubes can be a cost-effective do-it-yourself solution.

Tubes consist of magnets that are fully encapsulated within stainless steel tubing to create a strong magnetic field along the side of the tube to attract and retain ferrous material. Ends are fully seal welded and can be either plain or tapped for mounting.

We provide a variety of different styles and strengths designed to suit different applications or budgets using either Rare Earth (Neodymium) or Ferrite Ceramic magnetic material.

For standard applications the tubes are either 25mm or 25.4mm (1") diameter.  (Other sizes are possible e.g. 50mm dia). Construction uses type 304 or 316 stainless steel tubing. High temperature options are available.

For heavy duty applications and/or large or abrasive product, we also manufacture heavy duty tubes that are 38.1mm (1.5") square. These tubes should be mounted at 45 degrees to the direction of product flow and allow a wider spacing between tubes than standard round tubes.

Heavy Duty Rare Earth Square Magnetic Tubes

High strength tubes for large or abrasive products, custom made in any length up to 1 metre.

These tubes should be mounted at 45 degrees to the direction of product flow and allow a wider spacing between tubes than standard round tubes.

Heavy Duty Ferrite Ceramic Square Magnetic Tubes

Standard strength tubes for large or abrasive products, custom made in any length up to 1 metre.

These tubes should be mounted at 45 degrees to the direction of product flow and allow a wider spacing between tubes than standard round tubes.

Special Design Magnetic Tube

Special designs are available such as pointed ends or threaded ends with bosses.

Pointed ends make cleaning easier. Bosses give a more robust fixing method against a door or drawer front panel where the tube is fixed at one end only (like a probe or finger type magnet).
