Mechanical Discharge Bend Repair: UAE

The aim of the composite repair was to restore the integrity of the discharge bend having severe mechanical damage leading to through-wall scenario, the defect measured was 400mm X 10mm. This repair was engineered to ISO 24817:2015(E) standard.  



  • Composite Repair to reinstate integrity of 48” Discharge Bend.     

  • Required repair design pressure 6 bar.     

  • Required repair design temperature 60°C.     

  • The thickness required for restoring the integrity was engineered in accordance with       

       ISO 24817:2015(E), 9 layers of PCR-GX.  



  • Repair reinforcement by PCR-GX, 9 layers had to be done in a single day to achieve client strict    deadline.       

  • Precise compression was achieved never the less the complexity of the bend.



  • Surface preparation was done to Swedish standard Sa 2.5.     

  • PCR Metal putty was used to profile the defect and make it in line with the surface.     

  • PCR epoxy adhesive primer was applied on the bend to enhance the adhesion between the    substrate and PCR-GX layers.     

  • Application of 9 layers PCR-GX using hand layup.
