Bendel Tank & Heat Exchanger manufacturers above-ground single and double-wall storage tanks. There is a difference between the two. What are the differences between single-wall and double-wall storage tanks?
A double-wall tank differs from a single-wall tank in several ways, mainly design, fabrication, testing procedures, lifespan, price, function, technology and user benefits. The added environmental and safety impact of the “second wall” in storage tanks often becomes immeasurable over time.
Bendel double-wall tanks’ outer “wall” wraps and surrounds the inner tank, creating an interstitial space between the two walls. Any potential leak that may occur from the inner tank is captured in the sealed space, preventing a release into the environment and nearby work space. With the storage tank’s leak-monitoring provision, a warning of any type of breach or leak from the inner tank will be issued. The varying monitoring devices include electrical, mechanical, pressure, vacuum, hydrostatic, or manual dipstick.
The double-wall tanks from Bendel give our customers particular benefits that they demand, including protection against 
catastrophe, protection against environmental pollution, containment if a leak or breach should occur from the inner tank, and safety of personnel working with the tanks.
Bendel Tank & Heat Exchanger manufactures our single-wall and double-wall storage tanks up to 186” diameter and 75,000 gallon capacity. Storage tanks are designed, built and tested to meet industry standards including UL-142, NFPA-22, API-650, API-620, API-12F or ASME. Tanks are available in Carbon Steel, Stainless Steel or Nickel Alloy materials.
