Shell & Tube Heat Exchangers

High Pressure, High Temperature Exchangers
FBM-Hudson Italiana has developed design and manufacturing know-how to prevent hydrogen and high temperature embrittlement and cracking of the base material and the disbonding of the stainless steel weld overlays which may occur in Shell &Tubes Exchangers built for Hydrocraking, Hydrosulphurisation, Residue Desulphurisation, and similar applications.

A special development effort has been devoted to High Pressure Closures where FBM-Hudson Italiana offers the following type of closures

  • Flanged
  • Threaded
  • Ring Locked




High Efficiency Design Exchangers
FBM-Hudson Italiana designs and manufactures the following types of enhanced performances exchangers:

  • Rod Baffles Exchangers
  • Helix Exchangers ( Lummus Technology Heat Transfer Licence)
  • Low finned tubes exchangers
  • Special configurations for tubular reactors

Refinery Services

FBM Hudson Italiana are a leading company in design and manufacturing high pressure and high temperature shell & tubes heat exchangers for the above mentioned fields.


FBM Hudson Italiana products range includes, among others, conventional bolted-in with welded diaphragm exchangers and also more sophisticated threaded and lock-ring closures

Threaded type heat exchanger, named also Breech Lock Type HE, is a design and operational option to the conventional bolted closures and feature the following advantages:

  • Reduction of criticality of large bolted joints and lighter overall exchanger weight due to thinner channels
  • Faster opening and closure of the exchanger cover
  • No flames due to cutting or welding during maintenance of the exchanger
  • Re-setting of gasket seating in operation
