    Storage Section

  • ASME IV stamped for 160psi WP
  • Oversized 1/2" thick tube sheets minimize thermal stress
  • The weld which attaches the bottom tubesheet to the tank shell is completely isolated in order to eliminate flame impingement on the weld thereby significantly increasing tank life
  • Unique automatic self-indicating magnesium anode device increases tank longevity by providing maintenance personnel with tell tale evidence when the sacrificial anode needs replacement
  • Seamless 0.04" thick copper tubing is mechanically bonded over SA178A steel fire tubes
