Advantages of Tubular Heat Exchangers

Within the different geometries of heat exchangers present in the market, as plate and gaskets, welded plates, spiral or scraped surface heat exchangers, among others, the tubular type is one of the most traditionally used.
LOW MAINTENANCE COSTS

Since there is almost no need for spare parts (it is a completely welded construction).

HIGH WORKING PRESSURE

As there are no gaskets and the heat exchangers are completely welded, the design pressure can be over 100 barg. With regard to the mechanical calculations, we can check them according to different design codes (ASME Section VIII Div.1, AD Merkblätter, PED 97/23/CE), even using Finite Elements Analysis if required.

HIGH WORKING TEMPERATURES

Due to the tubular heat exchager is a completely welded construction and the absence of gaskets, there are no problems before high operation temperatures, as it occurs with other configurations (i.e. plate and gaskets heat exchangers).

 

PROCESSING OF PARTICULATE OR FIBRE PRODUCTS

 

Being the diameter of the inner tubes determined by the percentage, shape and size of the solids. Within the SACOME range of products, we have our monotubular heat exchanger S-TF20-I (Tube in Tube) being the most suitable tubular heat exchanger geometry for products containing big-sized particulates.

EASY INSPECTION AND DISASSEMBLY

In order to get a better access to the tube sheet and the inner tubes, we can consider flanged tube sheet designs as well as connections (flanges, clamps, DIN11851) in all the interconnections/bends between the modules.

HIGH SECURITY IN ASEPTIC PROCESSES

Tubular Heat Exchangers can be designed and manufactured with special geometries for pharma applications, as double tube sheet, that ensure that cross contamination doesn’t appear in the case of a leakage of a tube to tube sheet joint.

EASY TO ENLARGE

Due to its modular design. It is relatively simple to add some modules in series with the aim to increase the thermal duty and the temperature difference. Likewise, in case of being necessary to increase the process flowrate, some lines in parallel can be arranged by means of manifolds that split the product or service flow.
