What is ASME STS-1-2006 and why is it important for steel stacks?




ASME STS-1-2006 is an American national standard that covers the mechanical and structural design, material selection, linings, coatings, and inspection and maintenance of steel stacks. Steel stacks are vertical structures that support and convey hot gases from industrial processes, such as combustion exhausts, to the atmosphere. Steel stacks are subject to various loads and environmental conditions that can affect their performance and safety.

The standard was developed by the ASME Standards Committee on Steel Stacks (STS) and was first published in 2000. It was revised in 2006 to incorporate new information and experience from the industry and to address some issues that were raised by users of the previous edition. The standard applies to both single- and multiple-walled steel stacks, either of which can be lined or unlined. It also applies to steel stacks that are guyed or supported by another structure. The standard does not apply to stacks containing flammable gases, unless modified by an experienced individual.


The standard provides guidance on how to design and construct steel stacks that can withstand the effects of wind, seismic, thermal, corrosion, vibration, lightning, and other factors. It also specifies the minimum requirements for linings and coatings that protect the steel from deterioration and enhance its appearance. The standard also includes recommendations for inspection and maintenance of steel stacks to ensure their continued functionality and safety.


ASME STS-1-2006 is an important reference for engineers, designers, fabricators, contractors, owners, operators, inspectors, and regulators who are involved with steel stacks. It helps to ensure that steel stacks are designed and built in accordance with sound engineering principles and practices. It also helps to promote uniformity and consistency in the industry and to facilitate communication and cooperation among stakeholders.


The standard can be purchased from ASME as a print book or a digital PDF file. The digital PDF file is encrypted and requires both the Acrobat plug-in and the FileOpen Acrobat plug-in to view. The standard can also be accessed online from some websites that offer ASME standards downloads.


One of the main features of ASME STS-1-2006 is the use of limit state design (LSD) method for the structural design of steel stacks. LSD is a modern approach that considers the ultimate strength and serviceability of the structure under various load combinations and limit states. LSD allows for a more rational and economical design of steel stacks than the traditional allowable stress design (ASD) method.


Another feature of ASME STS-1-2006 is the inclusion of additional requirements for lighting and lightning protection, design for wind- and seismic-induced vibrations, and OSHA based climbing and access requirements. These requirements aim to enhance the safety and reliability of steel stacks and to prevent potential hazards and failures. The standard also provides guidance on how to perform wind tunnel tests and modal analysis to evaluate the dynamic behavior and response of steel stacks.


ASME STS-1-2006 is not intended to replace the judgment and experience of the engineer or the owner in charge of the project. The standard provides minimum requirements and recommendations that should be followed unless otherwise specified by the engineer or the owner. The engineer or the owner should also consider other factors that may affect the design and operation of steel stacks, such as local codes, regulations, standards, specifications, and practices. c481cea774
