LGH tubular graphite heat exchanger
LGH type tubular graphite heat exchanger is a series of products that have been formed before the floating head tubular graphite heat exchange type formed the industry standard. It is similar in structure to the GHA type and has the same technical characteristics. It differs from the HGA type in two ways: first, the model marks are only based on the heat exchange area; second, the effective length of the heat exchange tubes is different. This series of graphite heat exchangers are divided into two series: LGHA (inner and outer diameter of heat exchange tube φ22 / φ32) and LGHB (inner and outer diameter of heat exchange tube φ36 / φ50). Their structures are similar. The structure of this equipment is simple, compact, and has low fluid resistance, making it possible to manufacture large-scale equipment. This equipment is divided into two structures without gas-liquid separator and with gas-liquid separator.
