How can GRP Tank Covers perform better than Steel Tank Covers?

Steel can corrode and will deform easily under impact.  Tank Covers manufactured from steel are very susceptible to chemical attack in the highly corrosive environment found underneath an odour control tank cover within a Waste Water Treatment Plant. In addition, if hit by a heavy object steel may be subject to permanent deformation and may need to be replaced.

GRP Tank Covers are highly resistant to corrosion due to the use of high grade resins that are suitable for the environment that the cover will be exposed to.  This ensures that the Tank Structure remains structurally sound throughout its life and avoids unobserved corrosion to the underside of the cover that can potentially cause contamination from rust.

GRP performs exceptionally well under impact and would in many instances avoid the need for replacement. However, it the damage is considerable GRP the tank panels can be easily repaired in site.

How do GRP Tank Covers perform against chemicals?

On Waste Water Treatment & Sewage Treatment Plants chemical attack is a genuine concern and can cause significant damage to the plant and equipment.  Where Odour Control Tank Covers are required, such as Over Sludge and Treatment Tanks, the environment can be chemically aggressive resulting from the damp conditions and attack from Hydrogen Sulphide (NH2S), both of which can have a serious effect on steel.

The Solution

Relinea can offer a range of resins that are specifically selected to fit the chemical environment the product is being exposed to.  This combined with excellent design ensures that we will deliver a tank cover that is structurally strong throughout its life cycle and further avoid unobserved corrosion to the underside of the tank cover that can potentially cause cover failure.
