GGH new tube-type graphite heat exchanger
【Structure and characteristics】
Floating Head out to resolve the graphite heat exchanger tube allowable low temperature, in particular when the less than ideal for the heating problem, the company produces a new type of heat exchanger tube used the one-tube packing seal, single-tube packing seal on each graphite tube seal separate so that it can independentlyExpand with heat and contract with cold. Most suitable for the heater, evaporator (or film, falling film evaporator), and may bear a certain degree of thermal quenching radical. Also based on user requirements or conditions of design and manufacturing process are two of the structure of packing seals. Such as the graphite tube is damaged, replacement can be arbitrary at the scene.
【Technical characteristics】
Design temperature: ≤ 170 ° C heating
Design pressure: tube: ≤ 0.1MPa
Shell: ≤ 0.5MPa (according to user requirements to 0.7MPa)
Heat transfer area: 5 ~ 450 m²
The implementation of standards: reference HG/T3112-1998 "Floating Head Tube Graphite Heat Exchanger"
