Application of heat tracing pipeline
The heat tracing pipeline is produced by strict production process according to different site conditions, and the pseudo temperature detection is carried out by special personnel to adapt to different process conditions, so as to achieve the functions of fire prevention, anti-static, electromagnetic shielding, flame retardant, UV resistant sheath. The combination of multiple systems integrates multiple functions to simplify complicated projects. It plays a good guarantee role for remote work and remote diagnosis of the system. The heat tracing system makes the gas in the pipe non condensing and keeps the measurement above the dew point, so the measurement accuracy can be guaranteed , creating conditions for the computerization of central control. The new sampling tube adopts soft thermal insulation material for easy bending, maintenance, light weight and convenient installation. At present, it has been applied to the site of domestic power plants, metallurgical and chemical enterprises.
Principle and characteristics of heat tracing pipeline
The heat tracing pipeline is made according to the principle of electric heat tracing, and the corresponding length of pipeline can be made according to customer requirements. The material of inner core pipeline is PTFE, FEP, PFA and PE have better mechanical strength, chemical stability and aging resistance. The thermal insulation layer is wrapped with multi-layer thermal insulation and flame retardant materials to ensure the thermal insulation and uniform heating of sample gas. The outer layer is a nitrile rubber protective sleeve with good wear resistance.

Product description:
The heat tracing sampling composite pipe is an important part of the environmental protection monitoring system. It is composed of a set of corrosion resistant high-performance resin conduit, self temperature limiting tracing band and compensation cable, with an external insulation layer, and then coated with flame retardant polyethylene（ PE) protective jacket. The tracing band function can ensure that a certain temperature is maintained in the sampling tube, so as to ensure that the samples collected are consistent with the initial value as far as possible, and ensure that the environmental monitoring system can continuously and correctly collect the actual conditions such as sample gas composition and temperature. Different materials can be selected for the sampling conduit in the heat tracing sampling composite pipe. Medium, low and high temperature tracing bands can be selected for the tracing band. In addition, compensation wires, power lines, etc. can be added according to user requirements. It is a complex composed of a variety of devices, combining multiple systems on a limited cross-section. It is strictly prohibited to twist and drag on the ground during construction, and the pipe head sheath can only be removed when installing the contact. It is widely used in national environmental monitoring stations, indoor environmental monitoring, disease control centers, iron and steel plants, power departments, chemical industry, smelting, colleges and universities, and is trusted by users.
