FCC Internal Reactor Clamshell Expansion Joint as per KBR Specifications for South East Asia Petrochemical Plant
MACOGA Clamshell bellows is the best solution when a quick and unexpected replacement of the bellow is necessary. Clamshell bellows is a two-piece bellow which is welded around the existing unit.
The bellows is split in half longitudinally in our works. The halves are match-marked to ensure the bellows halves are aligned correctly. The clamshell is fitted accurately in position. A purge gas is set up to minimize oxidizing of the weld to ensure a good quality weld. The clamshell halves are then welded back together.
On this occasion, a petrochemical plant in South East Asia has bought from us a clamshell for the FCC internal reactor us with the following features:
- Clamshell
- Size DN 1300
- Material: Alloy 800H
- Singleply 1.50 mm thick
- PWHT on site
- Design Pressure 0,231 BARg
- Design Temperature +775 °C
We have the capacity to design and manufacture any Clamshell in a record time and we have always the best team of professionals to travel anywhere in the world to install it.
This unit has been assembled and installed on site by one of our teams of specialised engineers and technicians.
