BREECH-LOCK CLOSUREHIGH PRESSURE HEAT EXCHANGERS

• Invented and developed in 1960 by Standard Oil
  Co. of California . The first breech-lock was
  put into operation in 1966.
• Rights of technology remain with Chevron Research
  Company of California.
• In 1982, ABB LUMMUS HEAT TRANSFER became a
  licensee for the worldwide marketing of high
  pressure Breech-Lock heat exchangers.
• Since 1982 IMB was ABB LHT licensee and
  contributed to the further developement of the
  Breech-Lock internals design.
• Over 600 Breech-Lock high pressure heat
  exchangers are in operation worldwide.
  Approximately 300 have been manufactured by IMB.
• Finds applications in refinery units operating at
  high pressure and temperature with hydrogen rich
  streams such as Hydrocrackers.

• Closure Features and Advantages
• Hydrostatic Load Of Channel Cover Is Absorbed by
  the Channel Forging
• No Threaded Holes in Forging or in the Cladding
• Tightening of Gasket by Relatively Small Bolts
• Spiral Wound Gaskets are Used in the Girth Joints
• Channel Cover is Relatively Thin and Light
• Re-Tightening of Tubesheet Gasket During
  Operation Possible.
• Easy and Quick Maintenance
• All Channel Parts can be Removed Without Cutting.
• No Need of Welding During Re-Installation of
  Channel Parts.
