Flat Bottom Tanks

Dome Top, Flat Bottom Tank
 
Flat Bottom tanks are the most common used tanks in the industry.  All Flat Bottoms are designed in accordance with ASTM D-3299 or D-4097 standards.  They are the most cost effective way to store product.  The tank flat bottom requires a flat surface to give full support.

After selecting the Flat Bottom design, selecting the right top is the next step of the process. 

 
Closed Dome Top – This is the most frequently requested top style.  The ASME Flanged & Dished design gives it the most strength without adding thickness.  Each domed top comes standard with a top manhole with loose cover. 

Closed Flat Top  – A fixed, non-removable, flat surface.  If head space is at a premium, if agitator rails are a requirement or flat walking surface is required, the Closed Flat Top may be the best choice. 

Open Top with 90°Top Flanged Rim – When a Flat Cover, agitator rails or full access to the tank is required, the Open Top with 90° Top Flanged Rim option is the best choice. 

Open Top with Type II Top Rim  – When an open top will work and a Flat Cover and agitator rails are not required, this offers the most cost effective Flat Bottom tank design available.
