REVAMPING ACTIVITIES

REVAMPING ACTIVITIES ON STAINLESS STEEL EQUIPMENT

Existing process equipment are subject to various severe operation conditions and sometimes need revamping activities. Maintenance teams sometimes detect leaks linked to corrosion phenomena and they are sometimes constrained to stop production in order to repair the equipment.
Some repairs can only be done in specialized workshop able to act quickly in order to minimize production shutdown. This concerns for example modifications on heat exchangers such as retubing and replacement of some equipment parts, modifications on half pipe coil or dimple jacket reactors, modifications on columns such as replacement of tray, cleaning,…

HEAT EXCHANGER RETUBING, JUICE HEATERS, CONDENSERS, EVAPORATORS

During the use, the shell and tubes heat exchangers are subjected to severe operating conditions that can cause leaks in the tubes resulting from corrosion. Then, it’s necessary to program a retubing operation to make durable the equipment.

Labbe Process Equipment performs a lot of heat exchangers retubing each years. Indeed, Labbe Company has a 15 000 m² workshop specifically equipped for this kind of operations, we can work on all type of heat exchangers (shell & tubes or welding plates). All manufacturing phases are made in our workshop :

Moreover our permanent stock of stainless steel tubes and plates enable us to perform the heat exchangers retubing with the shortest delivery time in order to limit the production shutdown in factories.

This retubing operations can be performed on mechanically expamded or on welded tubes.

REPLACEMENT OF DIFFERENT HEAT EXCHANGERS PARTS

During heat exchangers using, it can be necessary to perform modifications on the equipment due to leaks or mishandling.

Labbe Process Equipment can perform modifications on this kind of equipment like :

  • Replacement of expansion joints, shell portions
  • Replacement or blind flanges/ doors, 
  • Modification of nozzles

MODFIFICATION HALF PIPE COIL

The half pipe coil reactors operate with sever conditions which can accelerate corrosion phenomene and caused some leaks on the half pipe coil. The installation must then be stopped and a repair of the equipment has to take place.  

Labbe Company regularly proceeds to revamping activities of half pipe coil reactor replacement of half pipe coil head or shell.

Totally independent for that kind of operations thanks to its 1000T of stainless steel plates stock and the internal control of cutting activitiesdished head, half pipe coil and shell manufacturing, Labbe Process Equipment is the leader for this kind of operation and guarantees the shortest delivery time for intervention.

STAINLESS STEEL COLUMNS REPAIRS

In order to increase the longevity of columns, it’s sometimes necessary to change one or more parts of distillation equipment.

Thanks to its 15 000 m² workshop and its internal stockLabbe can realize different operations on columns like:

  • Seal Cleaning and changing
  • Replacement of trays
  • Replacement of random packing
