Description
Technical field
The utility model relates to a kind of syndeton of exchanger tubes and tubesheets, belongs to technical field of heat exchangers.
Background technology
Shell-and-tube heat exchanger also known as tubular heat exchanger, be in the housing closed the wall of restraining as the simple wall type heat exchanger of heat-transfer area.This heat exchanger structure is comparatively simple, and operation is reliable, and available various structural material (mainly metal material) manufactures, and can use under high temperature, high pressure, be type most widely used at present.In prior art, being connected to shell-and-tube heat exchanger and will ensureing each junction No leakage of exchanger tubes and tubesheets, and the pulling force and pressure that between pressure medium and shell, the temperature difference produces can be born.Because the heat exchanger tube diameter of shell-and-tube heat exchanger is comparatively large, be therefore mostly connected by the mode of welding between exchanger tubes and tubesheets.During current exchanger tubes and tubesheets welding, heat exchanger tube outer end emersion tube sheet, weld seam is positioned at outside tube sheet, this connected mode easily causes tube plate deformation when welding on the one hand, and be easily corroded because weld seam contacts with heat-conducting medium, the sealing of exchanger tubes and tubesheets and tensile strength cannot ensure.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency; there is provided a kind of exchanger tubes and tubesheets syndeton, during its welding, tube sheet not easily produces distortion, and can available protecting weld seam; prevent weld seam to be corroded, improve sealing property and the tensile strength of exchanger tubes and tubesheets.
The purpose of this utility model is achieved in that a kind of exchanger tubes and tubesheets syndeton, it comprises tube sheet, described tube sheet offers installing hole, described installing hole the inner is provided with a circle flange, is fitted with heat exchanger tube in described installing hole, and described heat exchanger tube outer end flushes with flange outer end, described heat exchanger tube and flange outer sides are provided with weld seam, be fitted with sleeve pipe in described heat exchanger tube, described sleeve pipe outer end is provided with a circle flange, and described flange and tube sheet lateral surface fit.
Compared with prior art, the utility model has following beneficial effect:
A kind of exchanger tubes and tubesheets syndeton of the utility model, during its welding, tube sheet not easily produces distortion, and can available protecting weld seam, prevents weld seam to be corroded, improves sealing property and the tensile strength of exchanger tubes and tubesheets.
