Description:

Corrosion-resistant heated sampling composite pipes are an important component of environmental monitoring systems. They consist of an inner core made up of a set of corrosion-resistant high-performance resin conduits, supplemented by self-limiting temperature heating cables and compensating cables, wrapped in an insulating layer, and finally coated with a flame-retardant polyethylene (PE) protective sheath. The automatic temperature-limiting function of the self-limiting temperature heating cables ensures that a certain temperature is maintained within the sampling tube, thereby as much as possible keeping the collected samples consistent with the initial values, ensuring the continuous and accurate collection of sample gas by the environmental monitoring system. Depending on the actual composition and temperature of the collected sample gas, the sampling conduit in the corrosion-resistant heated sampling composite pipe can be made of different materials, such as PFA (perfluoroalkoxy).Fluorine monomerWith perfluoroalkylether copolymers), FEP (polytetrafluoroethylene)Fluorine etheneAndHexafluorobenzenePolymer Compositions (Copolymer), PVDF (Polyvinylidene Fluoride)Fluorine ethene)、PE (flame-retardant polyethylene), nylon 610, etc., heat tracing cables can be chosen in medium, low, or high temperature options. Additionally, compensation wires and power cables can be added according to customer requirements. The product's lifespan exceeds 15 years.

The Corrosion-resistant Heat Tracing Sampling Composite Pipe is a composite assembly consisting of multiple components, combining several systems within a limited cross-sectional area.

● Sampling System: Combinable with various types and materials of sampling tubes: Teflon PFA, FEP, PE, Nylon 610, 12, copper tubes, 316SS, 304SS, etc.

● Thermal System: High-efficiency insulating, flame-retardant, and lightweight thermal insulation; heating cables with automatic temperature control or constant power heating cables.

●Electrical system: Equipped with instrument signal cables, compensation cables, and control cables for instrument display and monitoring.

● Safety System: Adaptable to various process conditions, the systems are shielded and isolated using aluminum foil or metal mesh, achieving fire safety, static electricity prevention, and electromagnetic shielding. Some are equipped with waterproof film and reinforced flame-retardant and UV-resistant sheath. The combination of multiple systems integrates various functions into one, simplifying complex engineering. It provides a good guarantee for remote work and system remote diagnostics. The heating system prevents condensation of gas inside the pipes, maintaining measurements above the dew point, ensuring measurement accuracy. It creates conditions for centralized control and computerization. The reinforced outer sheath can prevent cross-contamination and damage due to other factors.
