Product description
High Quality Fixed Tube Sheet Heat Exchanger, The fixed tube plate heat exchanger consists of two tube sheets and a shell. Because
of its simple structure and wide application, fixed tube plate heat
exchanger is an energy-saving equipment for heat transfer between
materials. It is widely used in petroleum, chemical, petrochemical,
metallurgy, electric power, light industry and food industry. A process equipment. In
the oil refining and chemical installations, heat exchangers account
for about 40% of the total equipment, accounting for 30% -45% of the
total investment. With the development of
energy-saving technology, applications continue to expand, the use of
heat exchangers for high temperature and low temperature heat recovery
has brought significant economic benefits.
Structure
The fixed tube plate heat exchanger is composed of tube box, shell, tube plate, tube and so on. Its structure is more compact, the tube is more, the area is bigger under the same diameter, and manufacture is simpler.
The fixed tube plate heat exchanger is characterized in that the tube bundle is arranged in the shell, the tube ends are welded or expanded to fix the tube to the tube plate, the tube plates are welded directly to the shell, Of the inlet and outlet pipe welded directly to the shell, the tube plate outer circumference and head flange bolts fastening, the tube directly into the tube and head welded together, the tube bundle according to the length of the heat transfer tube set a number Block baffles. This heat exchanger tube can be divided into any number of partitions.
Features
The fixed tube plate heat exchanger has the advantages of simple structure, low manufacturing cost, convenient cleaning of the tube, and the tube can be divided into multiple paths. The shell side can be divided into two-way, wide range of specifications and widely used in engineering. Shell-side cleaning difficult for dirty or corrosive media should not be used. When the difference between the expansion is large, can be installed in the shell expansion joints, in order to reduce the tube, shell temperature difference arising from the thermal stress.
Fixed tube plate heat exchanger is characterized by:
1, the bypass seepage is small;
2, forging the use of less, low cost;
3, no leakage;
4, heat transfer area than floating head heat exchanger 20% to 30%.
Fixed tube plate heat exchanger has the following disadvantages:
1, the shell and wall temperature difference between the shell and tube wall temperature difference t ≤ 50 ℃, when t ≥ 50 ℃ must be set on the shell expansion joints;
2, easy to produce temperature difference between the tube plate and tube head is easy to produce temperature stress and damage;
3, the shell process can not be mechanical cleaning;
4, after the corrosion pipe together with the shell scrapped, equipment life is low.
