This 2021 edition supersedes the 2011 edition, introducing updated methodologies aligned with current building codes and advancements in structural engineering.

Guidelines for selecting durable materials, coatings, and linings, as well as recommended practices for fabrication and erection.

The standard applies specifically to stacks where the . Its scope includes:

Adjusting shell thickness; adding stiffener rings at critical heights. Asme Sts-1 2021 Pdf

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.

: Criteria for selecting vinyl, phenolic, or coal-tar epoxy systems to counter outdoor corrosion. 3. Structural Analysis and Load Combinations

Welding qualifications according to AWS D1.1 (Structural Welding Code - Steel). This 2021 edition supersedes the 2011 edition, introducing

: Guidelines on organic materials, refractory concretes, and geopolymer layers used to defend against chemical erosion.

: Applies to free-standing, guyed, or tower-supported stacks, whether they are on a foundation or integrated into another structure. Intended Use

: Clearer basic concepts for evaluating guyed cable tensions and structural foundation anchor interactions. Technical Specifications Summary ASME STS-1-2021: Steel Stacks - The ANSI Blog natural draft calculations

| | What the Standard Specifies and Guides | | :--- |:--- | | Mechanical & Structural Design | Sizing of the gas passage (height, diameter, shape), natural draft calculations, thermal expansion, and load calculations for dead, live, wind, seismic, and other environmental loads. | | Wind- and Seismic-Induced Vibrations | Procedures for analyzing and mitigating dangerous effects of vortex shedding, buffeting, and other dynamic excitations caused by wind and earthquakes. | | Material Selection | Specifications for steel shells, base plates, stiffeners, structural frameworks, guys, wires, cables, anchor bolts, nuts, washers, and welding electrodes. | | Linings & Coatings | Guidelines for selecting appropriate linings (for thermal insulation or corrosion protection) and coatings (e.g., vinyl, phenolic, coal-tar epoxy) to protect the steel from harsh process gases and environmental exposure. | | Lighting & Lightning Protection | Requirements for lighting and lightning protection systems based on existing building codes and federal regulations. | | Climbing & Access | Mandates for climbing and access equipment (ladders, platforms, cages) based on current Occupational Safety and Health Administration (OSHA) standards to ensure worker safety during construction, inspection, and maintenance. | | Fabrication & Erection | Recommended practices for shop fabrication, welding, field assembly, and erection to ensure the stack is built as designed. | | Inspection & Maintenance | Guidelines for developing a program for initial and periodic in-service inspections, as well as recommended maintenance procedures to ensure the stack’s long-term integrity and safety. |

: Formulas to calculate heat loss and temperature drop across the stack wall, which directly prevents process gas from dropping below its acid dew point. 2. Materials, Linings, and Coatings
