Norwesco : Above Ground Tanks : Frequently Asked

Because the wall thickness varies from top to bottom on a tank,it is not the best gauge for determining the quality of a tank.The very bottom of the tank is the thinnest part of the tank and is made that way to flex when the tank is empty or full.Generally the wall is thicker at the bottom of a vertical tank and becomes thinner toward the top.Norwesco : Above Ground Tanks : Frequently AskedBecause the wall thickness varies from top to bottom on a tank,it is not the best gauge for determining the quality of a tank.The very bottom of the tank is the thinnest part of the tank and is made that way to flex when the tank is empty or full.Generally the wall is thicker at the bottom of a vertical tank and becomes thinner toward the top.Manufacturing flat,elliptic,toro-spheric bottoms and Manufacturing flat,elliptic,toro-spheric bottoms and cones using the steel -09G2S,ST3,08X18H10T,AISI 304,AISI 321With ultrasonic examination of seam weld with heat treatment.
