Defying a chemical that “finds” leaks
Also known as caustic soda or liquid lye, sodium hydroxide is used to adjust pH in water and wastewater treatment and in the manufacture of chemicals, rayon, cellophane, pulp and paper, aluminum, detergents, soaps and a wide range of other products.
As for storage:
- Sodium hydroxide is a “slippery” chemical that tries to find leak paths.
- This chemical is extremely corrosive to tissue. It is also highly toxic if ingested.
- If sodium hydroxide is not kept at a specific temperature, it will crystallize and go solid.
A tank system and proper fittings from Poly Processing can reduce your risk with this hazardous chemical.
The Poly Processing Sodium Hydroxide System
The key to storing sodium hydroxide properly is strong, safe containment. Since the chemical is so corrosive, secondary containment is a must.
If secondary containment is already available, the IMFO® tank is recommended. IMFO® systems are ideal for Sodium Hydroxide Systems because their flange is actually a molded part of the tank, and not an insert that could leak or fail.
The IMFO® also ensures long-term performance of the overall system, since it eliminates the need to drill into the sidewall of the tank and install a mechanical fitting, which can create a maintenance issue for this chemical.
When secondary containment is not available, a SAFE-Tank® can meet this requirement. This “tank within a tank” extends the margin of safety by providing a system with 110% secondary containment.
The tank’s high-density crosslinked polyethylene construction means greater strength. It is so strong, in fact, that Poly offers a warranty of five full years on all tanks.
