Technical Field

The invention relates to the field of pipeline heat tracing, in particular to a pipeline heat tracing device.

Background

At present, the heat tracing method adopted in the pipeline heat tracing technology mainly comprises two methods: one is to bind the heat tracing pipe and the heat traced pipe by using iron wires, so that the heat tracing pipe and the heat traced pipe are fixed to achieve the heat tracing effect; the other is that the heat tracing device is used for connecting the heat tracing pipe and the heat traced pipe, and the heat tracing pipe and the heat traced pipe are fastened by bolts to achieve the heat tracing effect. These two heat tracing methods have the following disadvantages:

1. the heat tracing pipe and the heat traced pipe are directly bound by iron wires, the contact area is small, the heat tracing pipe is basically point contact, and the heat tracing effect cannot be achieved;

2. the heat tracing device and the heat tracing pipe are tightly connected by the bolts, although the contact area is increased, the close attachment can not be achieved, the heat loss is serious, and the heat tracing effect can not be achieved;

3. the heat tracing device and the heat tracing pipe are tightly connected by using a bolt, and the bolt is directly contacted with the heat tracing pipe, so that the bolt fastening force is insufficient or the pipe bracket opening is enlarged for a long time;

4. the bolt is not fastened and installed with proper fastening force, the installation precision is not enough, and the installation standard is not available;

5. the bolt fastening installation requires the heat tracing device to have corresponding thickness, which causes heavy parts and high cost.

In order to solve the technical problems, the invention aims to realize the following technical scheme:

the pipeline heat tracing device is arranged between the heat tracing pipeline and the heat traced pipeline and is tightly attached to the heat tracing pipeline and the heat traced pipeline; the outer surface of the pipeline heat tracing device is provided with a convex structure and a preformed hole for a metal binding belt to pass through; there is the stress point between protruding type structure and the metal ligature area, and local deformation takes place for the protruding type structure of atress extrusion under the synergism of metal ligature area and stress point, reaches closely the laminating when making pipeline heat tracing device and heat tracing pipe fastening connect.

The inner surface of the pipeline heat tracing device is provided with a groove-shaped structure, heat-conducting daub is smeared in the groove-shaped structure, the pipeline heat tracing device extruded by stress can be tightly attached to the heat tracing pipe under the action of the heat-conducting daub, and heat is not easy to lose, so that the heat tracing effect is achieved.

The invention has the beneficial effects that:

the heat tracing device for the pipeline adopts the metal binding belt to fasten the heat tracing device and the heat tracing pipe, so that the fastening force between the heat tracing pipe and the heat tracing device is more uniform, the installation is more convenient, trace deformation can be carried out while the strength is ensured, the heat tracing device and the heat tracing pipe are perfectly attached, the heat is not lost in the heat transfer process, and the heat tracing effect is achieved. The pipeline heat tracing device structurally reduces the weight and the cost. The pipeline heat tracing device has a definite field installation standard and is completely conformed to an acceptance standard.
