Includes mathematical models to calculate natural draft, draft losses, and thermal drops across the shell wall. 2. Materials, Linings, and Coatings ASME STS-1-2021: Steel Stacks - The ANSI Blog
Clause 11 of STS-1–2021 introduces temperature-adjusted ultrasonic thickness (UT) measurements. For metal above 140°F, UT velocities change; the standard provides correction curves. Also, creep damage assessment via replication (field metallography) is required at 50% design life if operating above 850°F.
In industrial environments, safety and structural integrity are paramount. One of the most critical components in power plants, refineries, and manufacturing facilities is the steel stack, which releases combustion gases into the atmosphere. The ASME STS-1-2021 Standard for Steel Stacks provides essential guidelines for the design, fabrication, construction, and maintenance of these crucial structures.
The 2021 version aligns more closely with updated ASCE 7 meteorological data, offering more precise aerodynamic damping coefficients.
