Since sodium hydroxide is so corrosive, proper secondary containment is essential. This eliminates the need of a sidewall tank fitting and a potential leak source since the flange is a molded part of the tank. Poly Processing can also provide heat trace systems and polyurethane insulation to solve the issue of crystallization at lower temperatures.
With chemical specific NSF 61 certification , high density cross linked polyethylene offers the tank strength required to safely store caustic soda while providing a cost-effective long tank life.
