Standards

We build all of our tank walls in accordance with the time-tested standards of ASTM D-3299 and ASTM D-4097 specifications for filament winding and contact molding respectively, with ASME RTP-1 (design by rules) fabrication capabilities.
All Belding Tank Technologies, Inc. corrosion barriers are built to a minimum thickness of 110 mil vs. 96 mil as specified by ASTM & ASME.

Tank Bottoms

FLAT & SLOPED – The majority of our Flat and Sloped Bottom tanks use a UNITIZED ONE-PIECE BOTTOM TO SIDEWALL CONSTRUCTION without a seam for greater structural strength. However, we don’t stop there. The tank bottom corners include a knuckle radius for maximum resistance against hydrostatic pressures, and corners are easier to clean to help eliminate product contamination.

CONE & DISHED – The majority of our Dished Bottom tanks also use a UNITIZED ONE-PIECE BOTTOM TO SIDEWALL CONSTRUCTION without a seam for greater structural strength and ease of cleaning. We utilize both FRP and Steel support structures, overlaying the steel support ring exterior with fiberglass for added resistance against chemical attack. The full circumference support helps eliminate uneven stresses on the tank sidewall.

Tank Tops

CLOSED – Belding Tank® Dome and Flat Top Heads come standard with our 20” or 24” loose cover top manhole with grab handle for convenient opening.

OPEN – Our Open Top tanks come standard with a 90° rim flange, with the option of a one, two or three piece cover. The 90° rim also allows for easy mounting of mixer rails, when required. As a cost saving alternative, a Type II rim is offered when a cover or rails are not required.

Note: All Belding Tank® 90° rims are formed by means of hand lay-up to the tank sidewall on a platen table to ensure uniformity.
