Tube Heat Exchangers with fixed tubesheets and with expansion joint in the shell
Devices are designed for heating and cooling of liquids and gases in
processes refining, petrochemical, chemical and gas industries.
Manufactured in accordance with
Heat exchangers are divided:
- intended — heat exchangers, refrigerators, condensers, evaporators;
- on a design — devices with fixed tube sheets (type N), with the temperature compensator on the shell (type K);
- at location — horizontal (H), vertical (V);
In devices pipes with smooth walls are applied.
Devices can be used in a macro-regions with temperate and tropical climates. Climatic modification «U» и «Т», category of a product 1 according to GOST 15150. Seismicity areas that can accommodate devices, should be inclusive to 7 points on a 12-point scale.
Depending on the temperature limits for use of the machine are made in the following versions:
- N — low temperature from -30 up to +100°С;
- N1 — low temperature from -40 up to +100°С;
- N2 — low temperature from -60 up to +100°С;
- N3 — low temperature from -70 up to +100°С;
- О — normal from -20 up to +100°С;
- S — medium from -20 up to +200°С;
- V — high temperature from -20 up to +300°С;
- V1 — high temperature from -20 up to +350°С.
