FIELD: heating.
SUBSTANCE: this invention relates to a heat exchange tube and to its manufacturing method; with that, heat exchange is performed between a fluid medium flow inside the tube and fluid medium outside this tube. Namely, fluid medium inside the tube is activated, due to which volume of its interaction increases and heat exchange efficiency is improved.
EFFECT: easier manufacture of a heat exchange tube at improvement of characteristics of adhesion and sealing between surfaces of an outer tube and an object placed inside the outer tube.
