CEMS heat tracing sampling tube
CEMS with heat sampling tube should be composed of corrosion-resistant high-performance fluorine resin tube and constant power heating tape core, plus a special glass fiber insulation layer, aluminum belt, and finally coated with flame retardant polyvinyl chloride (PVC) protection jacket composite.
CEMS with heat sampling tube has impact resistance, aging resistance, high temperature resistance, corrosion resistance characteristics, outer sheath with environmental protection, low temperature resistance, wear resistance, aging resistance, suitable for outdoor harsh environment use, glass fiber with good insulation, insulation, heat resistance, corrosion resistance, high mechanical strength, constant power with heat tape with temperature control accurate, refuse to overheat or no heat, to protect the reliable use, save electricity, with heat uniform, high thermal efficiency, low annual decay rate, long service life.
CEMS accompanying heat sampling tube can be used at minus 40℃ and ensure the continuous and correct collection of sample gas for environmental monitoring system.
CEMS heat tracing sampling pipeline structure: CEMS flue gas heat tracing sampling pipeline in the sampling conduit can choose different materials, such as PFA, FEP, PTFE, or stainless steel pipe. The heating tape can be used for medium, low and high temperature heating, in addition to adding compensation wires, power lines, etc.
