The invention relates to a heat transfer tube ( 9) for falling film evaporation having a heating medium surface (21) to be heated by a heating medium， a falling film surface (20) to have spent liquor passing over it， and being made from an sheet metal material. The falling film surface of the heat transfer tube is equipped with a multitude of wire bumps (WB)， each wire bump being spaced apart along the longitudinal axis (CC) of the heat transfer tube from a neighbouring wire bump by 3-300 mm， said wire bumps (WB) having a height (h) in the range 0.3 to 5.0 mm， a width (w) in the range 0.3-5.0 mm， and an inclination angle (a) versus a plane orthogonal to a longitudinal axis (CC) of the heat transfer tube in a range of 0-70 degrees. The invention also relates to a method for manufacturing said heat transfer tube.
