FIELD: petrochemical industry; hear and power industry; other industries; production of the sectional heaters for the fluid mediums. ^ SUBSTANCE: the invention is intended for heating of the fluid medium and may be used in the different technological equipment. The sectional heater contains the number of the connected among themselves by means of the layer pads sections composed of two collectors linked to each other by the pipes. The collectors of each section from two ends are supplied with the flanges and clamped among themselves by the transverse cross bars, tubes have the U-shaped form and are rigidly connected among themselves by the plates, and between the flanges of the collectors of the adjacent sections and the adjacent to them layer pads there are the installed annular washers and plugs made with the equal thickness with the washers. The washers and the plugs are arranged in the staggered order through the even quantity of the collectors. The invention ensures the rise of the heat transfer coefficient of the heater, the improved maintenance ability and the expansion of its technological capabilities. ^ EFFECT: the invention ensures the rise of the heat transfer coefficient of the heater, the improved maintenance ability and the expansion of its technological capabilities. ^ 2 cl, 10 dwg |
