5 Questions about the stainless steel tote tank bottom outlet

One of the advantages of utilizing stainless steel tote tanks is the ease of product discharge. We want to answer the most common questions about the bottom outlet for a standard stainless steel tote tank.

 - How do you discharge product from ss tote tanks?Valve_assembly

- Does the outlet have a valve?

- Where is the bottom outlet?

- What are the dimensions of the bottom outlet?

- Does the tote tank drain completely?

Every stainless steel tote container is going to have a bottom outlet assembly that is comprised of an elbow, nipple and valve. The standard diameter for the outlet assembly is two inches.  Our tote tanks have a sloped bottom that allows the product to flow freely to the bottom outlet. This allows for nearly complete product discharge and therefore almost eliminates any product residual in the tank.

The two inch bottom has a threaded connection. Those threads sit below and outside of the tank.  A stainless steel elbow is threaded onto the outlet pipe. Then a two-inch diameter stainless steel nipple is threaded into elbow.  The two-inch valve is threaded on to the other end of the nipple (more on the valve a bit later). Teflon tape and /or pipe dope is used when threading together the discharge assembly. 

The most common valve on a standard stainless steel tote tank is a ball valve made from 316 stainless steel. It has female NPT threads on each end.  All of the valves for stainless steel IBCs are equipped with locking reverse handles.  Typical household and industrial valves have the handle ‘in-line’ with the valve when open so it follows the flow of the product.  The valves on stainless steel IBC containers are CLOSED when in-line and open when perpendicular to the valve.  (If reverse valve handles were not used, the handles would get knocked off in transit.)  The standard stainless steel tote tank valve uses Teflon seats. The entire valve assembly can be removed, cleaned and replaced if necessary.
