Engineering Insight | Integrated Support Selection for Pressure Vessels

As a specialist in stainless steel vessel manufacturing, we merge multi-source technical standards to deliver a unified guide for support selection, enhancing design safety and efficiency.

Comprehensive Support Taxonomy

Six core support types address diverse operational needs:

1. Saddle Supports: For horizontal vessels, available in light/heavy types (120°/150° contact angles) with welded designs for DN1000-6000mm diameters.

2. Leg Supports: Standard for vertical pressure vessels, with pillar types (angle steel/pipe/H-beam) selected by media—e.g., angle steel for gas, steel pipe for liquids.

3. Lug Supports: Short/long/extended-arm variants for platform-mounted vessels; 4–8 lugs recommended for height-diameter ratios of 2–3.

4. Support Types: Applied to non-pressure vessels or small tanks (e.g., air receivers).

5. Skirt Supports: Ideal for tall columns (e.g., distillation towers), minimizing local stresses while managing dead weight, wind, and seismic loads.

6. Rigging Ring Supports: Suited for thin-walled or heavy vessels, reducing eccentric load risks associated with lugs.

Selection Methodology

Support choice must align with vessel geometry, operating parameters, and installation environment:

• Horizontal Vessels: Saddles leverage head stiffness for load distribution;
  
• Vertical Vessels: Leg/support types for low height-diameter ratios, skirts for tall equipment;
  
• Critical Cases: Rigging rings for thin-walled vessels, long-arm lugs for floor-mounted units.
  

Our engineering team employs stress simulation to validate support-vessel interfaces, ensuring robust performance under complex loads.
