MAC's standard Feed System's modular design permits quick assembly into many configurations to handle various lengths of material, and allows for later additions or changes. Systems can incorporate automated reject and accept controls. Both round and hexagonal material can be accommodated. Models are available for handling bars, shapes or tubing ranging in size from 1/8" (3.18mm) up to 7-1/2" (191mm).

Custom automated metric feed systems are available to handle bar, shapes and tube. Systems include automated reject and accept controls, belt driven or chain driven conveyors. Mac offers several different styles of feed systems and conveyors to meet the varying requirements of our customers' at the most economical prices.

For oil country tubular goods and similar large diameter product MAC offers our heavy duty conveyors that include the option of articulated rolls to handle upset pipe. These conveyors come in modular 3 meter sections so that configurations can easily be designed to handle any length of pipe. The systems are designed to be adjusted once during installation and to require no further adjustment for alignment during the life of the system. Each roll is driven by a separate motor allowing the spacing of tubes to be adjusted for optimum throughput and minimum untested ends. These systems can be produced to handle tubes up to 400mm in diameter with heavy wall.

For precision tubes and other high quality product the first priority is to prevent damage to the product by the handling system. To this end MAC offers a couple of different options. First of all is our conventional conveyors designed for lighter product which can be equipped with special handling mechanisms to lower or raise the bar or tube gently on to the conveyors from a feed table. MAC offers both pick and place type mechanisms used with conventional sloped feed tables as well as specially designed motorized feed tables that allow bundles of product (particularly long small diameter) to be lowered on to a flat table where specially designed belts and stops spread the product out and straighten out the product so that it can be properly placed on the conveyor. Alternative placement mechanisms are available that can lift bars or tubes up to conveyors that are higher than the feed tables.

Another alternative to conventional V roll conveyors for small diameter precision product is our V belt conveyors. These conveyors are built around sets of two belts formed in a v and offer the advantage that very unstable product cannot sag as is possible between V rolls and in addition because of complete contact with the soft bets minimizes the chance for damage.

Finally, MAC offers a series of v roll conveyors that are geared toward economy for those applications where the size of the product is not very small or very large and the delicacy of handling is not a concern. These conveyors are offered in various sizes and are composed of modular 6 foot sections that can easily be configured for any length and the most common diameters of product. Both steel and urethane rolls are available and there are options for both belt and chain drives. Feed tables are available as well as pockets for accept and reject sorting.

All of MAC's conveyors can be configured with any of our testers and benches to provide a complete off line test system. In addition each system comes with either a PLC for automatic control of the mechanics or our CONDUCTOR computer with sophisticated technology to monitor the entire line showing all aspects of the test process and creating combined reports from multiple testers.

The 65mm Coil Platform can use standard and segmented encircling coils or tangent (sector) coils, on magnetic and non-magnetic material. Other sizes include the 125mm and the 225mm.

By using a floating head option, the coil platform can follow the movement of the tube or bar under test. This feature is useful for tube weld mills and bar and wire drawing benches where the material under test tends to move around. The 65mm Coil Platform can be used with encircling or segmented eddy current applications. An advanced tangent weld inspection system can include the floating head option with the 65mm coil platform to inspect TIG and Laser welded tube.

Where rotating eddy current probes are being used, they are housed in a rotary headplate, mounted in rotary mechanics that include a motor for spinning the headplate with its test probes around the material under test. Current rotaries feature continuously variable high speed rotaries (1800 – 6000 RPM), capable of handling test material up to 191 mm (7-1/2”) diameter.

MAC’s Echomac® UT Rotary rotates ultrasonic transducers for shear-wave and compression-wave configuration at high throughput speeds. Standard models handle material from 6.3 mm to 220 mm (1/4” to 9”) at test speeds up to 400 fpm, depending on the size and condition of the test material.

Flux leakage test systems incorporate rotating test probes, mounted in a rotary headplate assembly. Current systems are available to handle up to 406 mm (16”) diameter and 19 mm (3/4”) wall thickness. Picture shows the headplate with test probe assemblies and magnetizing pole pieces for detecting longitudinal defects. Rotary mechanisms designed for detecting transverse defects are also available.
