Extensive customised documentation is a standard part of our product. Furthermore, special materials like Inconel and Hastelloy are often used. The processing and storage of these ma-terials is daily routine for us.
Catalyst Regenerator Standpipe FCC Expansion Joint
One multi-ply FCC expansion joint DN 1200 with an assembly length of 5000 mm for a like-for-like replacement. The Catalyst Regenerator Standpipe Expansion Joint is equipped with Ceramic Fibre Blanket insulation, removable outer shroud, Pantographic Linkage, Control Rods and Purge Nozzles. The bellows are made of Inconel 625 LCF and fitted with a permanent leakage detection (inter-ply monitoring). The expansion joint is prepared for the refractory lining on site.

On-site installation of Clamshell Expansion Joints
Successful on-site installation of two Clamshell Expansion Joints. kompaflex designed, fabricated and installed these over the existing FCCU Spent Catalyst Standpipe Expansion Joint. Our fully certified field specialist welded the 180° bellows segments on-site. The corrugated longitudinal weld of the Inconel 625 LCF bellows requires highest expertise and precision. The installed Clamshell were subsequently successfully tightness tested.
Expander load expansion joints DN 631
4 multi-ply expander load expansion joints DN 631 for a refinery in UK. The four expander load expansion joints had to match in-line pressure and compensate this force. This could be achieved as kompaflex versatile bellows manufacturing allows to manufacture to the exact diameter required. The pressure thrust force was verified with our test bench at presence of NoBo.

«Lurgi–Envirotherm – a subsidiary of the Frankfurt plant builder Lurgi AG in the mg technologies group – is working with ExxonMobil/USA and Germany’s Esso AG to develop an innovative procedure for converting or recycling refinery residues. A first commercial plant has been built for this purpose in the Esso refinery in Ingolstadt. Over 40 expansionjoints of widely varying type and size were supplied by kompaflex ag. The design had to take into account operating conditions of up to 650° C and pressure of 250 kPa in lines for transporting both solid and gaseous materials. Lurgi was guided in placing the order by the combination of flexibility and profound experience of kompaflex ag. During the design phase kompaflex ag proved its ability with its constant readiness. At the same time, the high quality requirements were of course fulfilled in the implementation. The plant has been operating in start-up mode since January 2000; the supplied expansion joints are functioning without problem.»
