Understanding Tank Implosion Risks
Tank implosion happens when the vacuum system fails or when fittings are not maintained correctly. An imploded tank on a slurry tanker is not only costly but also dangerous if the structure fails under pressure. From corroded steel to poorly adjusted valves, there are several causes that can be prevented through careful inspection and ongoing maintenance. Farmers who understand these risks are better equipped to avoid serious issues.
Key Checks to Avoid an Imploded Tank
When buying a new or second-hand slurry tanker, take the time to inspect the following:
- Protective coating – Hot-dipped galvanising provides a stronger and longer-lasting protective layer than paint when handling Farm Dairy Effluent (FDE). This extends the life of the tank and reduces the risk of corrosion.
- Tank interior – Always confirm the inside of the tank is not corroded or rusting. A weakened structure is far more prone to a tank implosion under vacuum pressure.
- Anti-implosion rings – Ensure the tanker has internal rings designed to prevent collapse. These anti-implosion rings significantly increase tank strength and are essential for long-term safety.
- Valves and adjustments – Check that vacuum and pressure relief valves have been recently replaced or serviced. These valves can corrode or shift out of calibration, increasing the risk of damage. Manufacturers generally set vacuum relief at minus 1 bar and pressure relief at plus 1 bar (both maximums).
Why Your Fittings Are Important
Anti-implosion rings and reinforced valves are specifically engineered to prevent collapse when slurry tankers are under heavy vacuum. Without them, even a small fault in the system can quickly lead to an imploded tank. By choosing tankers fitted with these safeguards, farmers reduce the risk of sudden failure and extend the life of their equipment.
Smarter Buying Decisions
A slurry tanker is a significant investment, so it pays to choose wisely. Look for suppliers who provide clear information. Always request maintenance history when buying second-hand and confirm that key parts, including relief valves, have been tested. By investing in a tanker that prioritises safety and durability, you minimise the chances of a tank imploding.
Final Thoughts on Preventing Tank Implosion
Effluent management equipment is vital for farm productivity, and preventing problems such as an imploded tank should be a top priority. By inspecting for corrosion, ensuring implosion rings are fitted, and checking valves are set correctly, farmers can safeguard their equipment and avoid unnecessary downtime. The right preventative steps today will protect both your investment and your farm operations tomorrow.
