Problems solved by technology

[0002] During testing, the sampling tube is usually exposed to corrosive substances such as acid and alkali, which will cause corrosion to the sampling tube and heating cables in the sampling system and other components, reducing the service life of the sampling system
If the heating cable is corroded, it will also short-circuit the busbar and other components in the heating cable, resulting in a decrease in safety

Abstract

The invention belongs to the technical field of industrial equipment, and relates to a composite pipe, in particular to a corrosion-resistant heat-tracing sampling composite pipe and a preparation method thereof. The corrosion-resistant heat-tracing sampling composite pipe is technically characterized by comprising a sampling pipe, a heat tracing band, a thermal insulation layer, a reinforcing layer and a protective layer. A heat tracing groove is cut in the outer part of the sampling pipe and is used for winding the heat tracing band on the sampling pipe; the heat tracing band is a constant-power heat tracing band; the outer layer of the heat tracing band is made of a basalt fiber / carbon fiber composite material; and the thermal insulation layer is arranged outside the sampling pipe, the reinforcing layer is wound outside the thermal insulation layer, and the protective layer is arranged outside the thermal insulation layer. According to the corrosion-resistant heat-tracing sampling composite pipe and the preparation method thereof, by adopting the heat tracing groove, the contact area of the heat tracing band and the sampling pipe is increased, the temperature conduction capacity is improved, the heat loss of the heat tracing band is reduced, on the other hand, the sampling pipe can be protected through the heat tracing band, and the high temperature resistance and the corrosion resistance of the sampling pipe are improved.

Description

Technical field[0001]The present invention belongs to the technical field of industrial equipment, and is related to a composite tube, which specifically relates to a corrosion-resistant thermal sampling composite tube and a preparation method thereof.Background technique[0002]When detection is performed, the sampling tube is usually contacted to acidity, basic, and the like, which have corrosive substances, which cause corrosion to other elements such as the sampling tube and the heat tape in the sampling tube, and reduce the service life of the sampling tube. If corrosion is causing the belt, it will cause a short circuit in a busbar in the tropical to cause a reduction in safety.[0003]In view of the defects existing in the above-mentioned existing sampling tank, the inventors are based on the manufacture of such products for many years, with rich practical experience and expertise, skilled chemistry, and continuous research and innovation in practice. It created a corrosion-resis...
