Brazing Steel To Steel Pipe With Induction

Brazing Steel To Steel Pipe With Induction  Objective: To braze O-ring Face (ORFS) sleeve or male connector to a steel tube. Material • Steel tube, 1 inch (2.54 cm) OD • O-ring Face Seal sleeve and a male connector fittings • Preform braze rings • White SureFlow flux • Steel support mandrel Temperature 1300 ºF (704 ºC) Frequency 200 kHz Equipment • DW-UHF-20KW induction heating system, equipped with a remote workhead containing two (2) 1.5 μF capacitors (for a total of 0.75 μF). • An induction heating coil designed and developed specifically for this application. Process A four-turn 2.75 inch (7.0 cm) ID helical coil is used for heating both the steel tube and the ORFS sleeve or the ORFS male connector. This coil is designed to braze either the sleeve or male connector to the tube. The parts to be brazed are assembled with flux and heated for 45 seconds. Pressure is applied to the tube to make sure it is inserted fully into the fittings as the braze ring flows. Results/Benefits Advantages : • Large Inner diameter of coil allows for easy loading and unloading of parts • With efficient energy coupling of the coil to the fittings overheating is avoided. https://dw-inductionheater.com/brazing-steel-to-steel-pipe-with-induction.html?feed_id=251012&_unique_id=667803160f4db
