    Magnet Material Maximum Operating Temperature
    REN Hi-G** Thin Wall***
    Standard 176°F (80°C) @ 52-55 MGOe
    High Temp 1 248°F (120°C) @ 48 MGOe
    High Temp 2 356°F (180°C) @ 38 MGOe
    High Temp 3 662°F (350°C) @ 30 MGOe
    * Pull values are average on contact and Gauss values are peak on contact.
    ** High-Temp magnets will have lower pull values versus standard temp design due to lower MGOe material
    *** Always consult a magnet professional before selecting thin wall tubes. Thin wall tubes are not recommended for products with abrasive characteristics or in manual clean designs such as grates.

    Magnetic Tubes

    Tube Magnets

    The product stream flows around one or more 1” diameter tube magnets located within the product streams that are attached to their housing via the tapped end holes. As tramp metal contaminants are captured, they move to the underside of the tubes eliminating tramp metal “wash-off”. Magnet tubes are easy to install and clean. They offer an efficient and economical ferrous metal filtration protection of your processing equipment. The magnet tubes may be used as individual units or part of multiple row arrangements.

    Tube Magnet

    Tube Diameter:

    • 1″ diameter (standard)
    • 3″ diameter (available for self-clean and quick clean only)

    Tube Length:

    • Available lengths from 4″ to 36″ in any increment. For sizes over 36″, MPI reviews per application to ensure that product will meet life expectancy requirements.

    Material Construction:

    • 304 Stainless Steel (standard)
    • 316 Stainless Steel

    Magnetic Tubes:

    • Ceramic
    • REN Rare Earth (standard)
    • Hi-G high-performance Rare Earth
    • TW Thin Wall high-performance Rare Earth

    Magnetic Material Temperature:

    • 400°F @ 3.5 MGO (ceramic)
    • 176°F @ 52-55 MGOe (rare earth) (standard)
    • 248°F @ 48 MGO (rare earth)
    • 356°F @ 38 MGO (rare earth)
    • 662°F @ 30 MGO (rare earth)

    Tube Coatings:

    • Stainless steel with no coating (standard)
    • Synergistic Coating [reference datasheet Synergistic Coating]

    Washdown/Liquid Tight Design:

    • Non-washdown for dry applications (standard)
    • Washdown design with liquid-tight tube for liquid or washdown applications

    MPI can manufacture your tube with any end plug required for easy installation into your application.

    Tube end design (end 1):

    • ¼-20 tapped (standard)
    • 3/8-20 tapped
    • Plain end
    • Bullet nose end
    • Bullet nose end ¼-20 tapped
    • Customer specified

    Tube end design (end 2):

    • ¼-20 tapped (standard)
    • 3/8-20 tapped
    • Plain end
    • Bullet nose end
    • Bullet nose end ¼-20 tapped
    • Customer specified

    MPI can manufacture your tubes with dead space on one or both ends to make metal removal easier. Note that there will be no magnetic protection in the dead space area and therefore should be located outside of the product flow area.

    Dead space length:

    • No dead space, full magnetic tube (standard)
    • 2” dead space (slightly magnetic at end of the tube)
    • 4” dead space (no residual magnetism at end of the tube)

    Dead space location:

    • Not applicable
    • End 1
    • End 2
    • Both ends
