Challenge
A short time frame due to critical power shortage stopping other major processes forced weekend work to commence. Rebuild and reinforce flanges and provide defect free corrosion protection.
Chemco’s Solution
Remove failed coating and hot wash components. Stencil existing profiles and make a template. Pre-abrasive blast and hot wash cycle to reduce soluble salts to an acceptable level.
Scope
Abrasive blast to AS 1627.4 Class 3 Application of RB 332 to the internals including flanges. Reinforce casting using Composite repair techniques to reinstate original strength. Holiday testing up to 12kV to detect and rectify defects
Results
Refurbishing the self cleaning strainer back wash boxes saved the customer 8 days in fabrication time and money ensuring production is not interrupted. RB 364 will provide long term protection coupled with the addition of composite reinforcement.
