Stainless Steel Water Tanks


Horizontal Hanson Stainless Steel Water Tanks

  • We manufacture stainless steel pressure vessels from 12″ to 144″ in diameter in 304 or 316 grade material.
  • Design working pressures range from 50 psig to 500 psig.
  • For fastest delivery, we have a large inventory of stock material and manufacture most of our own tank heads..
  • Vessels can be all stainless steel, or have some carbon steel items such as manways and supports to keep the cost down.

Vertical Hanson Stainless Steel Water Tanks

  • Tanks are available with mill finish or can be bead blasted or polished for a better appearance.
  • Machined or fabricated parts such as a quick opening closure can be incorporated in the design as necessary.
  • Although many of the stainless steel vessels we manufacture are air receivers or water tanks, most are for special industrial applications, especially if extreme operating temperatures are required..


  • 300 (304, 316 etc) series stainless steel is prone to cracking in certain circumstances.
  • Even very low concentrations of chlorides in water quickly creates cracks in stressed areas of a pressure vessel, especially when the temperature is over 120°F.
  • Bead blasting or shot peening and passivation of the wetted surface can delay or prevent this process.
  • Products containing chlorides must not be used for disinfection or cleanout as any contact can lead to stress cracking later.
  • Some sprayed on insulation products can cause a similar problem from the outside.
  • Cracking of stainless steel water tanks, however caused, is not covered by warranty.
