Shell & Tube Heat Exchanger
Shell & Tube Heat Exchangers
Tube type, material, wall thickness and tubesheet joint are set from fluid temperature, pressure drop and fluid type.
What is a shell-and-tube heat exchanger?
Tube type, material, wall thickness and tubesheet joint are set from fluid temperature, pressure drop and fluid type.
U-tube heat exchanger
A U-tube exchanger uses a U-bent, removable tube bundle. It is preferred where temperature difference is high and cleaning is frequent.
When plate, when shell-and-tube
For compact, low-to-medium pressure circuits see the gasketed plate heat exchanger ; for dirty fluid in the inner tube see the double-pipe heat exchanger . Air-side fins are on finned-tube heat exchangers .

Product Variants
Tank Suction Heat Exchanger
TANPERA TGB Series Tank Suction Heat Exchangers are designed to facilitate the transfer of liquids stored at low temperature or that solidify. They heat the liquid before pumping by reducing its viscosity. Widely used in chemical, food, and storage facilities.
Steam Generating Heat Exchanger
TANPERA TGB Series Steam Generating Heat Exchangers produce pure steam using energy sources such as dirty steam, thermal oil, or hot water. They meet the need for clean, reliable steam in hygiene-critical sectors such as food and pharmaceuticals.
Steam Condenser Heat Exchanger
TANPERA TGB Series Steam Condenser Heat Exchangers deliver high performance in hot-water production using the energy of saturated or superheated steam, or in cooling vapor-phase fluids under vacuum. Preferred for energy recovery in industrial plants, particularly power plants.
Frequently Asked Questions
One fluid flows in the tube bundle, the other on the shell side. The Tanpera TGB series includes fixed-tubesheet, removable-bundle (floating-head) and U-tube types.
A U-tube unit has a U-bent, removable bundle. Counterflow uses less area. It is preferred for high temperature difference and frequent cleaning or bundle renewal.
Tube, shell and tubesheet can be AISI 316, AISI 304, titanium, duplex, 904L, SMO or carbon steel. Gaskets are graphite, EPDM, NBR or spiral-wound. Selection follows fluid, temperature and corrosion.
The brochure lists chemical, petrochemical, food, marine, metallurgy, energy, paper, refrigeration, distillation, sugar, wastewater and biogas. Steam condenser, steam generator, gas cooling, tank suction, exhaust-gas and double-pipe duties sit in the same TGB family.
Exhaust-gas (waste-heat) units take hot water from high-temperature flue gas. Below about 130 °C on natural gas, condensation needs AISI 316; with H2S fuels below 130 °C, sulphuric acid risk needs a higher alloy.
Flows, inlet/outlet temperatures, phase (steam/condensate), operating pressure, fouling and material limits. Coding example TGB 2000 / 585 / 241 — length / diameter / tube count.
On U-tube and floating-head types the bundle is withdrawn for mechanical or chemical cleaning. Fixed-tubesheet tubes can be cleaned from both ends. Interval follows fluid fouling.
