Abstract

The invention relates to an anti-corrosion heat tracing sampling composite pipe. The anti-corrosion heat tracing sampling composite pipe comprises sampling pipes, compensation cables, a self-temperature-limiting heat tracing belt, instrument power cables, a waterproof layer, a tough layer, iron wires, an anti-abrasion layer, a heat insulating layer, an anti-corrosion layer, a flame-retardant layer, a protective film layer, a protective sleeve layer and a metal shielding layer. The four compensation cables are arranged in a square, the self-temperature-limiting heat tracing belt is located among the four sampling pipes, the compensation cables and the instrument power cables are located on the two sides of the self-temperature-limiting heat tracing belt, the outer surface of the anti-abrasion layer is wrapped by the tough layer, the outer surface of the tough layer is wrapped by the waterproof layer, the iron wires are arranged in the tough layer, the outer surface of the flame-retardant layer is wrapped by the anti-corrosion layer, the outer surface of the anti-corrosion layer is wrapped by the heat insulating layer, the outer surface of the metal shielding layer is wrapped by theprotective sleeve layer, and the outer surface of the protective sleeve layer is wrapped by the protective film layer. The anti-corrosion heat tracing sampling composite pipe is excellent in structure, long in service life, good in protective performance and high in practicality, and has broad application prospects.

Description

technical field [0001] The invention relates to the field of electric heating equipment, in particular to an anti-corrosion heat tracing composite pipe for sampling. Background technique [0002] Corrosion-resistant heat-tracing sampling composite pipe is an important part of the environmental monitoring system. It is composed of a group of corrosion-resistant high-performance resin, a conduit supplemented by a self-limiting temperature heating cable and a compensation cable to form an inner core, plus an insulation layer, and finally covered with Composite flame retardant polyethylene (PE) protective jacket. The automatic temperature limiting function of the self-limiting temperature heating cable can ensure that a certain temperature is maintained in the sampling tube, so as to ensure that the collected samples are consistent with the initial value as much as possible, and finally ensure that the environmental protection monitoring system can continuously and correctly col...
