Given the broad interpretation of "asme sts1 2021 pdf hot," I'll provide a general guide and highlight key areas:
Scenario: A 150-ft tall steel stack in a chemical plant operating at 850°F flue gas, carbon steel shell with refractory lining.
Problem after 8 years: Cracking at weld attachments of insulation support rings.
Root cause per STS-1–2021: Original design (using STS-1–2006) did not require thermal gradient stress analysis. The ring restraint created high secondary stresses during startup/shutdown.
Remediation per STS-1–2021: Remove rings, replace with sliding supports, perform elastic-plastic thermal fatigue analysis per new Annex R. asme sts1 2021 pdf hot
Insulation & Linings: For "hot" applications, the standard covers refractory linings and insulating concrete that can handle up to 2,200°F. Given the broad interpretation of "asme sts1 2021
The term "hot" in your query likely refers to the standard's specific focus on exhaust gas temperatures: Good for corporate subscriptions
Structural & Mechanical Design: Detailed principles for load calculations, including dynamic wind and seismic effects.
