SHELL AND TUBE HEAT EXCHANGER
We have developed expertise in heat exchanger design & development. We design and Manufacturer of Fixed tubes, Removable Tube Sheet, Vertical Shell and Tube Heat Exchangers, Stainless Steel Shell and Tube Heat Exchangers. Various Applications such as Steam, Compressed Air, Water, Oil, Acid, Paint, Gas, Brine, etc.
✓ Design and optimization of mass-produced heat exchangers.
✓ Design and optimization of heat exchangers manufactured as one-off, or at most in small series, for a specific application.
Heat Exchangers can be selected based on various types of Tubes such as
- 3/8” , 1/2” , 5/8” , 3/4” , 1” , 1.25” , 1.5” Plain Tube
- Integrally Fin Tubes 17FPI , 26FPI , 40FPI
- Tube, Shell and Tube Sheet MOC can be Copper, Brass, Cupro Nickel, MS, CS, SS304, SS316, Titanium, etc.
Selection Of Materials – (As per ASME Sec VIII and TEMA Standards)
✓ Shell – Boiler Quality Plates, SA 516 GR.60 70 & SS316
✓ Tubes – are usually of Copper, Admiralty Brass, SS 316, Cupro-Nickel etc as per service requirements.
These types of Heat exchangers are having two divisions one is a shell and the other is Tubes. Here One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. For this purpose, seamless/ERW or Rolled pipes are used for the shell. And Seamless tubes are used for Tubes.
