Engiplas produces Block and tube & shells heat exchangers for severe conditions.

The main types of these units are Blocks and tube and shells.

Our heat exchangers are ideal for heating, cooling and condensing chemically aggressive process streams.

Process-side parts are made of SiC. Graphite and Teflon lined.

Tubes

Ecarb-selects among four sizes of tubes made of ultra fine grain graphite, Graphec® iLP.  External carbon fiber wrapping (CFx) can be applied to enhance mechanical resistance and reliability.  Ecarb tubes have superior physical features and they are submitted to rigorous test, to ensure resistance and duration.  Material and test certificates are available on request.  Original length of Еcarb's tubes is 4500 Longer tubes, long up to 9 mt, are manufactured by thermal cementing.

Tube sheets

  

Tubesheets are the critical components of heat exchangers and they are continuously stressed during operations.  Tubesheets may be made of Graphec iLP or iSP, eventually reinforced with anti-erosion sleeves or layers, made of amorphous carbon, PVDF or PTFE.  Tubesheet thickness depends on design conditions and it is determined using high safety factor (minimum 9 tinmes than theorical values).

  

  

Нeaders

Availableconstruction graphite (graphec iLP or iSP), ebonite, materials: glass or PTFE lined steel.  Headers de- sign is adapted to specific service re- quirements.  Special long headers are made as separation chamber for partial conden- ser.  Headers may be equipped with mixers, anti-erosion baffles or conical conveyors.
