The 2021 edition continues the standard's focus on comprehensive safety and structural integrity. Key areas covered include:
Industrial facilities require robust, durable structures for venting exhaust gases safely away from the ground level. , a standard published by the American Society of Mechanical Engineers, acts as the definitive guide for the design, fabrication, and construction of steel stacks.
ASME STS-1-2021 is the latest edition of the Steel Stacks standard, published by the American Society of Mechanical Engineers (ASME). It replaces all previous versions, most notably ASME STS-1-2016, and introduces several fundamental changes, particularly in how wind loads are calculated.
: Static pressure exerted by geographic regional winds.
: Includes guidelines for selecting steel materials, as well as the application of linings and coatings to prevent corrosion and erosion.
ASME STS-1-2021 serves as the definitive industry standard for the design, fabrication, erection, and inspection of self-supporting steel stacks. These structures are critical components in industrial facilities, including power plants, refineries, and manufacturing sites. The standard provides guidelines to ensure structural integrity under various environmental loads (wind, seismic, thermal) and operational conditions.
If you currently use the 2013 or 2016 versions, the 2021 edition introduces mandatory changes that could affect your stack design or retrofits.
