OVERVIEW: Chemcote were approached by a Steel Manufacturing customer to extend the life of the externals and save replacement of conical, 6mm wall pipe sections for fume suppression pipe.
INDUSTRY
ENVIRONMENT
Abrasive Coke Breeze ranging in temperatures from 60-100°C
SUBSTRATE
Externals of Conical Sections of 6mm wall pipe sections
CHALLENGE
Inspections found wall thickness to be worn internally after 25 years in service. This was prevalent immediately beyond the weld from the straight sections in the concentric reducers.
SOLUTION
Critical areas to be identified by NDT for the application of the RB 332AR & Alumina Tiles. Basalt Fibre wrap was chosen over Carbon Fibre due to its natural characteristics providing a combination of improved temperature and abrasion resistance.
SCOPE
Mechanical Clean and solvent wipe.
Trowel application of RB 332AR to the externals
Application of RB 332AR on the weld lows to ensure a firm bed for the tiles to be laid on
Application of Hex Alumina tiles using the RB 332AR providing an abrasion resistant adhesive
Application of Basalt Fibre wrap using RB 300 Series and top coat using RB 300AR
Final top coat using RC 500GTC
OUTCOME
Strainer was completed in time for re-assembly. RB 332 will provide long term protection coupled with the non-toxic anti-foul coating will prevent marine growth for a minimum of 5 years.
