Direct drag pressure pushing the stack in the direction of the wind.
For a typical industrial combustion exhaust stack, STS-1-2021 is your go-to code. For a high-pressure flare stack, you must use this code in conjunction with ASME B31.3 and BPVC Section VIII.
: Primarily designed for nonflammable gases (e.g., combustion exhaust) at low internal pressure. For flammable gases, the standard requires additional modifications and compliance with codes like ASME B31.3 ASME BPVC Section VIII The American Society of Mechanical Engineers - ASME Key Design Pillars Asme Sts-1 2021 Pdf
The standard is the definitive guide for the modern design of steel stacks, reflecting the latest industry practices in material science, structural dynamics, and safety. Its most impactful update is the adoption of ultimate wind speeds, aligning it with contemporary building codes. For any professional involved in the design, construction, or maintenance of steel stacks, obtaining the official PDF and thoroughly understanding its provisions is an essential investment in operational safety and engineering excellence.
The ASME STS-1-2021 standard serves as the primary authority for the design, fabrication, and maintenance of steel stack structures, establishing essential safety guidelines for industrial exhaust systems. It addresses critical engineering aspects, including dynamic wind loads, structural integrity, and material selection, with a focus on mitigating risks like corrosion and stress-corrosion cracking.

If you are involved in a project requiring structural calculations or material specifications, I recommend downloading the ASME STS-1 2021 PDF from the ASME website to ensure compliance. ASME STS-1-2021 Steel Stacks | PDF - Scribd
Detailed principles for structural integrity, including load calculations for dead loads, live loads, and wind/seismic-induced vibrations. : Primarily designed for nonflammable gases (e
If you currently use the 2013 or 2016 versions, the 2021 edition introduces mandatory changes that could affect your stack design or retrofits.
The ASME STS-1-2021 standard is an indispensable tool for ensuring industrial safety, structural longevity, and code compliance. By adopting the revised wind, seismic, and vibration guidelines outlined in this edition, engineering firms and plant operators can safely push the boundaries of modern industrial exhaust design.
