Heat Exchangers are a device which transfers heat from one medium to another; heat is transferred by conduction through the exchange materials which separate the mediums being used.
A shell and tube heat exchanger passes fluids through and over the tubes, whereas an air cooled heawt exchanger passes cool air through a core of fins to cool a liquid.
Site Maintenance & Fabrication Services designs and manufactures shell and tube Heat Exchangers. These are most commonly used and come in three types of construction: The Fixed Tubesheet, the U-tube and the Floating Tube Sheet.
We fabricate TEMA configurations, from single pass to multiple pass exchanges.
We design and fabricate according to a client’s requirements, specifications, process, need and application in accordance with ASME and TEMA codes.
Our scope also includes the following:
- Manufacturing of a new heat exchanger, gas coolers and air coolers.
- Retubing of a heat exchanger (both on and off-site).
- Plugging of tubes.
- Tube to tube-sheet welds repairs.
- Retubing of condensers on and off-site.
- Expansion of tubes.
