Tube Heat Exchangers with floating head with a U-tubes
Devices are designed to heat liquids and gases in industrial processes refining, petrochemical, chemical, oil, gas and other industries and are manufactured according to the ТS 3612-023-00220302-01.
The cooling environment in refrigerators and condensers is water or another nontoxical, not explosive and not flammable liquid with a boiling temperature with a pressure of 0,07 MPa over 60°С.
Devices can be used in a climatic regions with temperate and tropical climates. Climatic modification «U» и «Т», category of a product 1 according to GOST 15150.
The devices are designed to be installed in geographic areas seismicity to 7 points in the Russian Federation adopted on 12-point scale.
When choosing vehicles produced heat engineering calculations, as well as selected materials that provide resistance to the corrosive effects of environments.
