INDUSTRY COMPONENT

Support Legs/Skirt

Support legs and skirt components provide structural stability and protection for storage section feedwater tanks in industrial systems.

Component Specifications

Definition
Support legs and skirt components are engineered structural elements designed to provide vertical support, stability, and peripheral protection for feedwater tanks within storage sections of industrial systems. These components ensure proper weight distribution, prevent tank deformation, protect against external impacts, and maintain alignment with connected piping and equipment. They are critical for operational safety, vibration dampening, and thermal expansion management in high-pressure and high-temperature applications.
Working Principle
Support legs transfer the tank's weight and operational loads to the foundation through vertical compression, while the skirt provides lateral stability and protects the tank base from environmental and mechanical damage. The design incorporates load distribution principles, material strength calculations, and thermal expansion allowances to maintain structural integrity under varying operational conditions.
Materials
Carbon steel (ASTM A36/A283), stainless steel (304/316L), or alloy steel with corrosion-resistant coatings; typical thickness: 6-20mm for legs, 3-10mm for skirt; weld quality per AWS D1.1.
Technical Parameters
  • Bolt Holes 4-8 M16-M24 per leg
  • Skirt Height 200-800mm
  • Load Capacity 5-50 tons per leg
  • Surface Finish Hot-dip galvanized or epoxy coated
  • Base Plate Size 300x300mm to 600x600mm
  • Height Adjustment ±50mm
Standards
ISO 9001, DIN 18800, ASME BPVC Section VIII

Frequently Asked Questions

What is the primary function of support legs and skirt on a feedwater tank?

The support legs provide vertical load-bearing capacity to transfer tank weight to the foundation, while the skirt offers lateral stability, protects against impacts, and prevents debris accumulation under the tank.

How are support legs designed to handle thermal expansion?

Support legs incorporate sliding plates, expansion joints, or flexible connections that allow controlled movement during thermal cycling while maintaining structural stability and preventing stress concentrations.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
