Slope Bottom Tanks

Dome Top, Internal Sloped Bottom Tank
Sloped Bottom tanks are offered as both Internal and External.  All Sloped Bottoms are designed in accordance with ASTM D-3299 or D-4097 standards.  Internal Sloped Bottoms come standard with a 1” minor and bottom core to sit flat on your support pad.  External Sloped Bottoms require the customer to provide a sloped support pad.  Belding Tank’s standard pitch is ¼ inch per foot to allow drainage to the low side of the slope.  Either bottom design requires full bottom support.

After selecting the Sloped 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.'
