Unique Design Requirements For Chemical Heavy Steel Frame Pipe Rack
1. Multi-layer layered bearing design 2–4 layers of pipe support beam on single column, bear different weight steam, oil, chemical medium pipelines, classified load calculation for each layer.

2. Anti-seismic & anti-explosion structural reinforcement Chemical plant risk of explosion impact load, column and beam adopt thick box section steel, increase lateral bracing system to resist instantaneous impact force.

3. Heavy anti-corrosion system for chemical corrosive gas environment Multi-component heavy-duty coating system: shot blasting Sa2.5 + zinc rich primer + intermediate epoxy paint + top anti-chemical finish paint; offshore chemical base adopts full hot-dip galvanizing.

4. Expansion joint reserved for high-temperature pipeline High temperature pipeline thermal expansion will pull steel frame, designers reserve sliding support and expansion gap to eliminate additional stress.

5. Fire separation structural layout Separate fire zone steel trestle according to chemical medium risk grade, match fire-resistant coating on key support components.
