How to Avoid a Slurry Tank Implosion

Just what a dairy farmer doesn’t want! (An imploded tank on a Slurry tanker) Find out how this can be avoided.

This could have happened due to a number of different reasons, but we thought we’d share some basic tips from our experience, on how to avoid this from happening.

When buying a Second hand or new slurry tanker look out for:

• Generally hot dipped galvanizing will provide the steel pressure/vacuum tank with a more superior protective coating than paint when it comes to Farm Dairy Effluent (FDE). This generally provides the tank with an extended life
• Confirm the inside of the tank is not corroded or rusting out as this weakens the tank and is more prone to imploding
• Confirm the tanker has internal ‘Implosion rings’ as this adds to the strength of the tank
• Confirm the vacuum and pressure relief valves have been recently replaced. They can corrode over time or the adjustments may not have been set correctly which can cause damage. Generally manufacturers will set the Vacuum relief at Minus 1 bar and Pressure relief valve at positive 1 bar (both maximum’s).
