Component Specifications

Definition
Tank shell plates are fabricated steel plates that constitute the primary containment walls of industrial tanks, designed to withstand internal pressures, external loads, and environmental conditions. They are typically rolled and welded into cylindrical or spherical shapes, with thicknesses calculated based on design pressure, material strength, and safety factors. These plates provide structural integrity and leak-tight containment for liquids, gases, or solids in various industrial applications.
Working Principle
Tank shell plates operate on the principle of membrane stress distribution, where internal pressure creates hoop stress (circumferential) and longitudinal stress along the tank axis. The plates are designed to distribute these stresses uniformly, maintaining structural stability and preventing deformation or failure under operational loads. They work in conjunction with other tank components like heads, nozzles, and supports to form a complete pressure boundary.
Materials
Carbon steel (ASTM A36, A516 Gr.70), stainless steel (304, 316), alloy steel, aluminum alloys, or composite materials depending on application requirements. Material selection considers corrosion resistance, strength, temperature tolerance, and compatibility with stored media.
Technical Parameters
  • Width 1500-3000 mm
  • Length 6000-12000 mm
  • Surface Finish SA 2.5 blasted or pickled

Frequently Asked Questions

What factors determine the thickness of tank shell plates?

Plate thickness is calculated based on design pressure, material yield strength, corrosion allowance, safety factors, and applicable codes like ASME BPVC or API 650. Hydrostatic pressure from liquid height is a key consideration for storage tanks.

Can tank shell plates be repaired if damaged?

Yes, damaged plates can often be repaired by welding or patching following qualified procedures, but replacement may be required for severe corrosion, cracks, or if repairs compromise structural integrity beyond code allowances.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
