Double-pipe heat exchanger

Intended for heat exchange between the technological environments with temperatures ranging from minus 60 to plus 550 ° C in the chemical, petrochemical, oil, gas and other industries, except for nuclear power.

The vessels can be operated in the areas with seismicity up to 6 points inclusive.
