HEAT EXCHANGER

Single-pass shell-and-tube heat exchangers for soap applications are simple in design
A number of straight tubes are sealed between two perforated tube sheets
High nickel content materials are recommended to avoid cracking of soap with high salt content
The optimum diameter of the tubes is 12 mm inside and 14 mm outside
Soaptec supplies shell-and-tube Heat Exchangers with O.D. 14 mm
tubes thk .1mm in AISI 316
It allows the heating of neat soap and pre-evaporation of some moisture before flash inside the Atomizer
Soaptec’s heat exchangers are always fitted with expansion joint
All heat exchanger pressure tests are done at 14 bar
Soaptec supplies heat exchangers completely built
Inlet and outlet flanges for both soap and steam are usually built following UNI standards
The shell, the cones, the plates and the diaphragms are built in stainless steel AISI 304
Inlet and outlet flanges for both soap and steam are usually built to UNI standards. On request also built to ANSI standards
Soaptec’s Heat Exchanger project pressure is 10 bar (both tube and
shell side)
Project temperature is 150° soap side and 185° vapor side
On request Soaptec certificates according to ASME SECTION VIII, 1st DIVISION standards
Project pressure soap side 4 bar.
Project pressure jacket 1 bar.
Filtration degree 0,8 mm.
