Heat exchanger is one of the most critical engineered systems used in process plants and units. Shell and tube heat exchangers provide larger heat transfer area in relatively less space, making them the preferred means of heat transfer in large process plants.
They are also versatile in terms of the material of construction (MOC) used for the tubes as well as the shell. Shell & Tube HE may be designed with a wide range of corrosion resistant materials apart from borosilicate glass such as graphite, Silicon Carbide (Hexoloy), Tantalum, Steel, titanium, etc. to name a few.
We have expertise in shell and tube HE with tubes made of borosilicate 3.3 glass, Silicon carbide as well as graphite. The shell, depending on application, may be of glass, mild steel, stainless steel, PTFE lined, etc. Tube sheet of virgin PTFE is used and the tubes are sealed using ring fittings.
The shell and header are also sealed with PTFE O ring. Hence all components in contact with the process fluid are corrosion resistant and sealed properly to avoid leakage.
With glass tubes, we can provide Shell and Tube HE with HTA up to 40m2. With graphite tubes, the HTA can go up to 1000m2.
Due to higher heat transfer area, easy maintenance and repair, and flexibility of design and operation, shell and tube heat exchangers have become very popular and the preferred means of heat transfer. They are also recommended for use in GMP applications.
Multiple pass shell and tube heat exchangers ( up to 4 passes) are also available on request.
