Petrochemicals / Oil & Gas

Tailor-made
solutions

Expansion joints for oil & gas applications must fulfill a wide range of technical requirements. In this industry, high temperatures, pressure and corrosive/abrasive media are to be expected. The thermal processes result in large movements and a high number of cycles, which must be absorbed by the expansion joints.

Expander load expansion joints DN 631

Four 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.

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.
