HEAT-EXCHANGERS pipe-in-pipe
Purpose:
Heat exchangers are designed for heating and cooling media in technological
processes in oil, chemical, petrochemical, gas and other industries
Ability to operate in areas with seismicity of 7 magnitude or more is determined by seismicity calculation according to SNIP 11-7 - 81 (taking into account a particular size and layout of the devices).
