Induction Heating Aluminum Pipe

Induction Heating Aluminum Pipe For End Forming With High Frequency Induction Heater Objective Through heating the top 2” (50.8mm) of aluminum oxygen tank to form a rounded end with a hole for oxygen valve Material Aluminum oxygen tank with open end 2.25” (57.15mm) diameter, 0.188” (4.8mm) wall thickness Temperature 700 ºF (371 ºC) Frequency 71 kHz Equipment • DW-HF-45kW induction heating system, equipped with a remote workhead containing two 1.5μF capacitors for a total of 0.75μF • An induction heating coil designed and developed specifically for this application. Process A five turn helical coil is used to heat the open end of the oxygen tank. The tank is heated for 24 seconds to reach 700ºF (371 ºC). Results/Benefits Induction heating provides: • Uniform through heating • Fast, energy-efficient heat • Fast, controllable and repeatable process • Hands-free heating that involves no operator skill for manufacturing
