The sampling heat tracing composite pipe is an important component in the environmental monitoring system. It consists of a set of corrosion-resistant high-performance resin pipes supplemented with constant power, self-controlled temperature heating cable and compensation cable to form the inner core, plus insulation layer. Flame-retardant polyethylene (PE) protective jacket composite. The automatic temperature limiting function of the self-control electric heating cable can ensure a certain temperature in the sampling tube, so as to ensure that the collected samples are consistent with the initial values as much as possible, and finally ensure that the environmental monitoring system continuously and correctly collects the sample gas. According to the actual conditions of the sample sample, temperature, etc., the sampling tube in the anti-corrosion sampling heat-treating composite tube can be made of different materials, such as PFA (tetrafluoroethylene and perfluoroalkyl ether copolymer), FEP (tetrafluoroethylene and Hexafluoropropylene copolymer), PVDF (polyvinylidene fluoride), PE (flame retardant polyethylene), nylon 610, copper and stainless steel, etc., electric heating can use medium, low, high temperature electric heating cable, in addition, according to User requirements, add compensation wires, power lines, and so on.

The corrosion-resistant sampling heat tracing composite pipe is a composite body composed of a plurality of devices, and a plurality of systems are combined in a limited cross section.
? ?Sampling system
? It can combine various types and materials of sampling tubes: Teflon PFA, FEP, FE, nylon 610, 12, copper tube, 316SS, 304SS, etc.
? ?Electric heating system
? Efficient insulation, flame retardant and light thermal insulation; automatic temperature-limited electric heating cable or constant power electric heating cable.
? ?Electric system
? It can be equipped with instrument signal cable, compensation cable and control cable to meet the meter display monitoring.
? ?Security system
? Adapt to different process conditions, the system is shielded by aluminum foil or wire mesh to achieve fireproof, anti-static, electromagnetic shielding, and can also be attached with waterproof membrane, enhanced flame retardant, UV protection jacket. The combination of multiple systems combines versatility into one, making the complex project simple and simple. It provides a good guarantee for remote work and remote diagnosis of the system. The heat tracing system keeps the gas inside the pipe from condensing and keeps the measurement above the dew point, so the measurement accuracy can be guaranteed, creating conditions for the central centralized control computer. The reinforced outer sheath prevents damage due to crossover and other factors.
