Design of Steel Tanks - The Constructor

A rectangular steel tank is shown in Fig.The rectangular steel tanks are made of steel plates with flat bottom.The widths of steel plates generally adopted are 1.20 m,1.25 m and 1.30 m depending upon availability of the plates.the thickness of steel plates should not be less than 6 mm.Choosing a Butt Weld Joint PreparationIn the process of selecting a suitable butt weld joint preparation for thick plate (greater than 1 in),the most apparent consideration is unquestionably the joint economy the practice of minimizing the volume of weld metal required to fill the joint.AWWA SATANDARD WELDED CARBON STEEL TANKS FOR WATER STORAGE Table 15 Weld design values\u2014tank plate joints Efficiency-percent Type of Joint Tension Compression Double-groove butt joint with complete joint penetration 85 100 Double-groove butt joint with partial joint penetration and with the unwelded portion located substantially at the middle of the thinner plate * *In which Z is the total depth of
