Fireproof Multi Storey Steel Frame Construction For Petrochemical Reaction Chamber

As the main vertical load-bearing members, they bear vertical and horizontal loads from beams, equipment and other structural components. Hot-rolled or welded wide flange H-section steel is typically used, with cross-section size determined according to calculated axial force, bending moment, slenderness ratio and other requirements. For enhanced stability, the bottom of the frame column is firmly connected to the foundation through foundation bolts, and the top is reliably connected to the frame beam.

Primarily bears the vertical load generated by equipment, materials and operators on the floor or platform, transferring it to the frame column. Generally, H-shaped steel similar to frame columns is selected and connected with the frame columns by welding or high-strength bolts to form rigid or semi-rigid joints, ensuring overall stability and spatial stress performance. The span and spacing of beams are determined according to equipment layout and process requirements, with common spans between 6-12 meters.

Steel has excellent toughness and ductility, capable of absorbing and dissipating large amounts of energy under natural disasters such as earthquakes and wind disasters or other accidental loads to avoid sudden brittle failure of the structure. In petrochemical production where sudden dynamic loads may occur (such as vibration from equipment failure or explosive impact), this performance ensures the structure maintains carrying capacity and stability, improving overall production safety.

Steel offers higher strength and lower density compared to traditional concrete structures. Under the same load, steel structural frames are significantly lighter, reducing foundation bearing pressure and lowering foundation project costs and construction difficulty. This lightweight property also facilitates transportation and installation, particularly beneficial for large petrochemical projects built on soft soil foundations.

In petroleum refining and chemical synthesis processes requiring specific heights and spaces, our high-rise steel structural frames support various reaction towers including catalytic cracking towers in refineries and cracked gas separation towers in ethylene units. These frames provide reliable support for tall, large-diameter towers carrying complex chemical reactions and material transfer processes.

For large compressors, pumps and other petrochemical equipment typically installed on elevated platforms, our multi-story steel structure platforms enable optimal equipment arrangement at different heights to achieve smooth process flow connections. In natural gas processing plants, for example, large compressor units are often installed on second- or third-story platforms supported by our steel frames.
