Within pressure limitations, slip-on flanges are preferred because <br />the inside surface of the attaching weld is readily available for rounding edges and grinding. If operating pressure dictates the <br />use of weld neck flanges, the inside surface of the attaching weld is in the throat of the nozzle, making repair of surface <br />irregularities by grinding rather difficult. <br />NACE International 7 <br />
