GH-type floating head Tubular graphite heat exchanger
【Structure and characteristics】
Tubular heat exchanger graphite impregnated graphite tube by the extrusion of graphite plate heat exchanger increases with the composition of adhesive bonding control, placed in a steel cylindrical shell, the permeability of settings at both ends of graphite or other anti - Corrosion head material system, respectively, formed by fastening bolts. A fixed tube sheet, a free floating, the floating tube sheet generally cylindrical seal packing seal, but also with "O"-ring seal.
This equipment is usually graphite tube assembly Φ22/Φ32mm extrusion. Also produce Φ25/Φ37mm, Φ36/Φ50mm graphite tube assembly.
The device structure is simple, compact, fluid resistance small, can produce large-scale equipment. However, pressure, temperature lower than the block-hole. Apply to non-strong shock, vibration smaller occasions, and for cooling (condensation) for a good browser.
The equipment I type and II type, I-type non-gas-liquid separator, II-type with gas-liquid separator, the condenser should be chosen for the band structure of gas-liquid separator.
【Technical characteristics】
Design pressure: tube: 0.3MPa (DN ≤ 900), 0.2MPa (DN> 900)
Shell side: 0.5MPa (DN ≤ 1100), 0.4MPa (DN> 1100)
Design temperature: tube: -20 ℃ ~ 130 ℃
Shell side: -20 ℃ ~ 120 ℃
Heat transfer area: 5 ~ 810m², based on user needs the design, manufacture heat exchangers over 810 m².
Implementation of standards: HG/T3112-1998 "Floating Head Tube Graphite Heat Exchanger"
【The main advantage】
1) All are easier to check the seals
2) low pressure drop
3) Product specifications large
4) high heat transfer efficiency
5) price
【Uses】
This series of products can be used as a cooler, condenser.
