Will Your Chemical Storage Tank Resist Environmental Stress Cracking?

Environmental stress cracking occurs when microscopic cracks form in polyethylene tanks as a result of storing aggressive chemicals. Over time, these imperceptible cracks combine to form larger cracks, which can lead to leaks or even tank failure. If cracks occur, it’s recommended that you replace the polyethylene tank.

How to Keep Your Chemicals Cool When the Heat Is On

With some chemicals, it’s critical to keep them cool because they will lose their concentration when they heat up. Sodium Hypochlorite is a prime example of that. As it heats up, it starts to lose its strength, and it begins to release gas and free radicals. Its strength can diminish dramatically with heat and UV.

So it’s important to keep the chemical as cool as possible from the moment it arrives at your facility. Other chemicals are similar—if they become too warm, they won’t perform as well as you need them to.
