ASME STS-1:2026

Annotation of standard text ASME STS-1:2026 :

This Standard applies to stacks where the primary supporting shell is made of steel (steel stacks). It applies to both single-and multiple-walled steel stacks, either of which can be lined or unlined. This Standard also applies to steel stacks that are guyed, or to certain aspects of tower stacks. The stack may be supported on a foundation or from another structure. This Standard covers mechanical and structural design, material selection, linings, coatings, and stack inspection and maintenance. Additional requirements for lighting and lightning protection, design for wind- and seismic-induced vibrations, and OSHA based climbing and access requirements are included. This Standard is intended for use with stacks containing nonflammable gases, such as combustion exhaust gases at low internal pressures, though may be applied to those stacks containing flammable gases after modification by an experienced individual.
