[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] Steel pipe is a hollow long steel strip, which is widely used as a pipeline for conveying fluids, such as oil, natural gas, water, gas, steam, etc. In addition, it is light in weight when bending and torsional strength are the same, so it is also widely used in manufacturing mechanical parts and engineering structures. Among them, stainless steel water pipes are usually used for conveying water. The stainless steel water pipe with a model of DN80 has a wide range of applications, such as water supply pipes and fire pipes in residential areas, water pipes in and out of water plants, and fire pipes and water supply pipes on both sides of the road.

[0004] Stainless steel pipes are affected by the outside temperature when in use. Although the outside of the pipe is covered with an insulation layer, it is difficult to avoid the temperature drop or even freezing of the water or other fluids inside by relying solely on the insulation layer in the low temperature environment in winter. Therefore, it is necessary to install a pipe heater on the outside of the pipe. Although the current pipe heater can achieve pipe heating, the heating area is limited, multiple heaters need to be arranged at intervals, and the heating is uneven and the heating efficiency is low. The wires will be exposed to the outside and the arrangement is messy, especially when multiple heating elements are set, which is more likely to cause messy arrangement. Utility Model Content

The heating plates 13 are arranged at intervals in the rectangular groove of the heating half pipe, so that the pipe is heated evenly and the heating efficiency is improved.

[0028] like Figure 2 As shown, the line collection device 2 includes a first semicircular shell 21, a second semicircular shell 22 is arranged at one end of the first semicircular shell 21, and the upper and lower ends of the first semicircular shell 21 and the second semicircular shell 22 are connected. A first cylindrical member 28 is arranged on the outer surface of the first semicircular shell 21, and the first cylindrical member 28 is fixedly connected to the first semicircular shell 21; a second cylindrical member 29 is arranged on the outer surface of the second semicircular shell 22, and the second cylindrical member 29 is fixedly connected to the second semicircular shell 22. The cylindrical member is an output tube for the wires, and the heating plate 13 is collected through the line collection device 2, and the neutral wire and the live wire are classified, and connected to the outside through the first cylindrical member 28 and the second cylindrical member 29.

[0029] A first semicircular side shell 23 is provided at the front and rear ends of the first semicircular shell 21, and the first semicircular side shell 23 is connected to the first semicircular shell 21. A second semicircular side shell 24 is provided at the front and rear ends of the second semicircular shell 22, and the second semicircular side shell 24 is connected to the second semicircular shell 22.
