欠点があった。However, when such a conventional pipe heater is used for heating a liquid in, for example, an ultrasonic cleaning tank, the shape of the internal heater wire is changed due to ultrasonic vibration. Problems such as collapse and bobbin 2 movement, short-circuit between the heater wire and the inner surface of the outer pipe 1, etc. occur frequently. One or several aged (reduced diameter) sheathed heaters were considered to be inserted, but even in this case, the ultrasonic powder causes the magnesium powder to flow and the outer pipe 1
A gap is created between the inner surface of the sheathed heater and the sheathed heater, heat conduction from the sheathed heater deteriorates, and some parts become extremely hot. As a result, partial overheating and burning occur, and solvent heating of trichlene, etc. When used for the above, there was a defect that the solvent was thermally decomposed or the heater was broken.

る。In the present invention, as shown in FIG. 1, for example, aluminum or copper having a lower melting point than that of stainless steel having a thickness of, for example, 7 mm is provided in the outer pipe 1 having a bottomed stainless steel having an outer diameter of 50 mm and a thickness of 3 mm. After inserting the inner pipe 4, and inserting the sheathed heater 5 having an outer diameter of 27 mm, which has been sufficiently swaged to 15 to 20% into the inner pipe 4, these are placed in a furnace at 700 to 800 ° C. The copper inner pipe 4 is melted.

しても良い。As a result, the inner pipe 4 is melted to completely fill the gap between the inner surface of the outer pipe 1 and the outer surface of the sheath heater 5 as shown in FIG. . If this space 6 is created, the heat transfer from the internal sheath heater to the upper flange and the terminals will be poor, so there is the effect of preventing the temperature rise in that part, but as shown in FIG. The heat insulating material 7 may be filled.

る。Since the pipe heater and the method for manufacturing the same according to the present invention have the above-described structure, since the inner pipe 4 is firmly fixed to the outer pipe 1 and the sheath heater 5, strong ultrasonic vibration is applied. However, the central sheathed heater 5 is not displaced, and as a result, damage to the sheathed heater 5 is prevented and a gap is prevented from being formed between the outer surface of the sheathed heater 5 and the inner surface of the outer pipe 1. In addition, the heat transfer is extremely good, so that partial overheating and burning will not occur.
