Sodium Hydroxide Tanks & Containers

Sodium Hydroxide Tank Specifications

  • HDLPE - High Density Linear Polyethylene with 1.9 specific gravity rating and meets ASTM D-1998 standards - 600 psi hoop stress design.
  • HDXLPE - High Density Cross Linked Linear Polyethylene with a 1.9 specific gravity rating and meets ASTM D-1998 standards - 600 psi hoop stress design.

Full Drain Option:

  • SUMO™ (Snyder Unitized Molded Outlet)
  • Available on all single wall Snyder tanks in the 2000 to 12,500 gallon range.
  • Encapsulated 316SS threaded ring with PVC adapter.

Double Wall Sodium Hydroxide Tanks

  • Mini-Captor™ & CAPTOR™ Containment Systems. 35 to 10,000 gallon range.
  • Primary Tank is made of HDLPE or HDXLPE depending on customer preference and has a specific gravity rating of 1.9.
  • Secondary Containment Tank is made out of HDLPE with a specific gravity rating of 1.5.

Sodium Hydroxide Tank Fittings

  • Fitting: PVC & CPVC (schedule 80), PP or 316SS.
  • Gasket: (EPDM) - Ethylene Propylene Diene Monomer.
  • Bolt: 316SS

Heat Tracing & Insulation

  • Sodium Hydroxide is susceptible to freezing at 55 degrees Fahrenheit. In order to prevent the freezing of Sodium Hydroxide or crystallization you may need to keep the contents of your tank heated with a heat maintenance system.
  • Heat tracing and insulation is available on both our single and double wall Snyder polyethylene tanks.

Sodium Hydroxide Tank Plumbing

  • Sodium Hydroxide tanks require flexible connections with fittings.
  • You need to allow for %4 lateral and vertical contraction / expansion of the Sodium Hydroxide Tank.
  • The flexible connections, additional piping and valves must be supported independently of the tank sidewall and dome.

Sodium Hydroxide Tank Venting:

  • Our Sodium Hydroxide Tanks are designed for use at atmospheric pressure. Pressuring or a vacuum can damage the tank and cause deformation. Venting equipment needs to be sized appropriately to limit pressure or the creation of a vacuum in the tank to a maximum amount of 1/2" water column.
  • Pneumatically filled tanks may require additional pressure relief.

Sodium Hydroxide Tank Foundations & Restraints

  • Tanks should be positioned on a smooth surface such as a concrete or asphalt pad that can provide adequate support for the tank. Make sure the pad is clean, smooth and level so there is no deflection in the bottom support of the tank. Seismic restraints should be attached using seismic anchor plate attachments per your local seismic code.


  • Product should not be stored or exposed to temperatures in excess of 100 degrees Fahrenheit.
