Commercial fertilizer production challenges engineers when it comes to high pressures, temperatures, and corrosion resistance. The specific environment requires special (custom) designs and high-quality corrosion resistant materials. MACOGA is the specialist in this field and has developed a wide range of Expansion Joints that are being successfully used in the fertilizer production process.

The client is the largest private granular urea producer in North Africa and is capable of producing 1.50 million metric tons per year.

On this occasion we have designed and manufactured a very special Expansion Joint that combines critical design and operation factors (pressure, temperature, fluid, etc.) with special construction elements that make this unit an extraordinary piece.

Main design and operating parameters and constructive features:

  • Type: Single Unrestrained Reinforced MRR Series
  • Size: DN 1150 (46”)
  • Medium: Hydrogen + Hydrocarbons
  • Design Pressure: 41,30 BARg (599,01 PSIg)
  • Test Pressure: 63,00 BARg (913,64 PSIg)
  • Design temperature: 482,00 °C (899,60 °F)

Materials:

  • One ply Bellows in SB443 N06625 (Inconel 625) Annealed
