The standard applies to steel stacks where the primary structural shell is constructed of steel. It explicitly covers stacks handling nonflammable gases—such as low-pressure combustion exhaust—vented safely into the atmosphere.

ASME STS-1-2021 completely rewrites the seismic section to harmonize with ASCE 7-16’s Risk-Targeted Maximum Considered Earthquake (MCER) ground motions. Owners in high-seismic zones (e.g., California, Alaska, Japan) must pay close attention to Chapter 8, which introduces new response modification coefficients for stacks lined with brick or castable refractory.

Beyond core design, ASME STS-1-2021 incorporates essential safety and operational requirements: STS-1 - 2021 * Publisher: * 2022

: Covers single- and multiple-walled stacks, whether they are lined or unlined.

The standard is divided into several critical areas of focus: Mechanical Design * 9780791874813

If a stack handles flammable or pressurized gases (such as flare stacks), the standard requires engineers to implement modified designs. These modifications ensure compatibility with companion safety codes, notably ASME B31.3 (Process Piping) and Section VIII of the ASME Boiler and Pressure Vessel Code (BPVC) .
