The laminate Corrosion Barrier is the Inner Surface and Interior Layer combined. The glass content of the Corrosion Barrier shall be 27% ± 5% by weight. The most important feature to any fiberglass tank in the corrosion industry is the Corrosion Barrier of the tank. Each tank Belding Tank Technologies, Inc. manufactures is built using a male mold to help ensure a smooth, resin rich internal finish to aid in corrosion resistance.
Belding Tank utilizes the time-tested industry standards ASTM D-3299, ASTM D-4097 and ASME RTP-1 (Subpart 3A – Design by Rules) for tank design, using high quality materials to ensure tank longevity. All Belding Tank Technologies, Inc. corrosion barriers are built to a minimum thickness of 110 mil vs. 96 mil as specified by ASTM & ASME
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.
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
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.
