Description

Closed steam heat tracing lower-mounted crane pipe for automobile

Technical Field

The utility model relates to the technical field of oil filling riser, in particular to an automobile closed steam heat tracing lower-mounted oil filling riser.

Background

In the production or sale and storage practice, some easily-coagulated media, such as crude oil, heavy oil and the like, gradually increase in viscosity due to gradual temperature reduction and even coagulation during pipeline transportation, and thus production is influenced. Therefore, when conveying such media, heat preservation measures must be taken to maintain a certain temperature of the material. The heat tracing is a constant temperature or heating mode adopted for preventing the materials in the pipeline from crystallizing, solidifying or meeting the process requirements and keeping the materials at a certain temperature.

In the practical process, the crane pipe adopting the steam heating spacer sleeve has the following problems:

1. the elbow and the rotary joint of the oil filling riser can not be additionally provided with a spacer sleeve, so that the heating effect is poor;

2. the steam pipeline leading in the crane pipe heating spacer bush and the pipeline between the spacer bushes are generally flexible pipelines (mostly adopting stainless steel metal hoses), and are affected by the rotary motion of the crane pipe in the use process, so that the problems of loosening of joints, hose kinking and the like can be caused, steam leakage is easy to cause, and the environment and personnel injury is caused;

3. the steam heat tracing pipe of the oil filling riser is generally positioned at the tail end of the heat tracing pipe of the pipeline and is greatly influenced by the fluctuation of the pipe network.

4. The conventional crane pipe steam tracing is that steam tracing is filled between the heating spacer sleeve and the crane pipe outer wall, so that the heat conduction performance is poor, and the heat conduction is uneven.
