Magnetic Tubes

Magnetic Tubes

Ruggedly constructed from stainless steel, our grate tubes have tapped mounting holes at each end for easy bolt-in installation. The one inch (1") diameter round tubes have 1/4"-20 mounting holes. Standard tube lengths range from 4" to 48" long.

The Optimal Magnetic Tube for the Application

Industrial Magnetics, Inc. now offers an array of magnetic tube designs to meet the changing needs and requirements facing today's processing facilities. Our new Opti™ Series of Rare Earth magnetic circuits were specifically designed to address the standards for magnet separators set forth in schemas such as FSMA, HACCP, GFSI, BRC, FSSC and SQF, and meet a minimum and measurable threshold of repeatable magnet performance.

Opti LogoThere are seven (7) Rare Earth circuit configurations in the Opti Series family of magnetic circuits in 1", 2", and 3" OD tubes designs. Each circuit is designed to optimize values which have been identified and earmarked as critical measurements for the specification, purchase, audit, verification and validation requirements for magnetic separation equipment.

A highly durable Ceramic magnet configuration is also available and is recommended for placement early in the processing stream to capture both small and larger tramp metal pieces, such as nails, bolts, washers, etc. that can damage other equipment.

Note that a special tube coating is available in all configurations for especially abrasive product applications.
