Tube flare tools consist of large style tube spreaders that are used for radiator cores. The tube spreader is rolled across the tubes while pushing down to flare the end of the tube. It also consists of small tube spreaders that are used for small cores. The tube spreader is rolled across the header flaring all the tubes.
Tube flaring is a process of forming the end of a tube into a funnel shape so a threaded fitting can hold it. When a flared tube is prepared, a flare nut is slipped onto the tube and the end of the tube is flared. During tube installation, the flare is seated to a fitting with the inside of the flare against the cone-shaped end of the fitting, and the flare nut is screwed onto the fitting, pulling the inside of the flare against the seating surface of the fitting.
A tube magnet is constructed of cylindrical permanent magnets contained within a thin stainless steel tube, generally 25 mm diameter. The length of the tube is usually manufactured to suit the specific location. The tube magnet is either installed singly or in multiples within the process, or built into grates, through which the food material flows. A typical grate composed of tube magnets. The grates themselves can be built into drawer type assemblies for manual removal to facilitate cleaning or can be arranged for automatic removal actuated pneumatically.
