The barrels range in size from 120” long and 1500lbs up to 360” long and 5000lbs.
2. Purpose and Background: This system is designed for the magnetic particle inspection of 40’ long gun tubes and weighing up to 7000 pounds. The system is equipped with an internal 12,000 ampere FWDC magnetizing power supply complete with reversing DC demagnetization. At the headstock end is located a stationary broad V nest to rest the gun tube for loading. After loading the powered headstock rollers are elevated, lifting the gun tube for inspection. The powered tailstock is fitted with heavy-duty idler roller rests. The powered headstock roller rest and the tailstock rests are to rotate gun tube in either direction. The head and tail stock rollers have independent controls to rise and lower to elevate the ends of the gun tube for drainage. The unit is fitted with a 25” diameter coil with an enclosed powered mobile 42” wide mobile hood with full flame resistant side curtains. The pneumatically operated retractable roof opens to allow the loading of the gun tube from the overhead crane. The unit is supplied with a heavy duty encircling coil for longitudinal magnetization and an aluminum central conductor for circumferential magnetization.

This notification shall also include for review the test results of all preliminary tests performed. If acceptable, the Proving Ground representatives will schedule an inspection and the contractor shall await the arrival of the Proving Ground representatives before starting the official inspection.

Final acceptance is defined as the act of an authorized representative of the Government, by which the Government assumes ownership of existing supplies/equipment and/or approves specific services rendered, as partial or complete performance of the contract (i.e. testing, training, and delivery of all required technical documentation).
8.8. Preservation, Packaging and Delivery Instructions: The contractor shall utilize standard commercial methods of preservation and packaging appropriate for machine tools and acceptable to commercial carriers.
