Fibreglass Pods

Industry:

Chemical Transport,

 

Date:

Dec 2010,

 

Substrate:

Fibreglass tanks,

 

Products:

Chem-tect™ RB 332,

 

Environment:

Ferric Chloride & 33% Hydrochloric Acid,

 

Challenge:

The pods have been in service for 25-30 years and have been re-lined by a reputable fibreglass tank manufacturer around 10-12 years prior. The pods have predominantly carried ferric/HCL for most of their life. There were osmosis blisters in the applied lining and surface cracking allowing the fibreglass structure to be exposed to the stored acid.

Chemco’s Solution:

Carry out exploratory cleaning and pH neutralisation ensuring the fibreglass is not beyond its structural ability to remain in service for another 10 years. Removing the internal lining by scrapping/grinding and abrasive blasting. Hot washing is also recommended to open up the pores and assist in the pH neutralisation process.

 

Scope:

  • Removed Fibreglass from around roll-over combing and bands around the circumference.
  • Chip away the failed internal coating
  • Assess corrosion damage to steel work and internal shell
  • Heat internals of tank to assist with leaching process
  • Whip abrasive blasted internals and hot  wash to release contaminants. 600 multi directional matting & RB 300 series on to damaged areas.
  • 1st coat of RB 300 on entire surface
  • Application of 1000µm of RB 332 to pipe internals.
  • Application of 2 veil coats of RB 300
  • Hot wash/sand externals to assist in the removal of wax as best as possible

 

Results:

Using the RB 300 series for Fibreglass Tank internal lining  will provided 10 years protection.
