  • Intrados induction heating for tight radius rotary draw bend
    Patent number: 6038902
    Abstract: A boost bend method of making tight radius bends in boiler tubes, such as bends having a radius of 1.times.D or less, in which a selected portion of the intrados of the tube is heated in a controlled manner thereby reducing the necessary tube wall thickness relative to the diameter of the tube for 180.degree. bends. Tubes bent using the method may have wall thicknesses of about 6.6% of the tube diameter and suffer less than about 7% thinning of the extrados tube wall.
