Step 1: Understanding the Concept:
Pressure vessels used in food and chemical processing industries must comply with strict engineering design codes to ensure structural safety under high pressure.
Step 2: Detailed Explanation:
IS 2825 is the Indian Standard code of practice for unfired pressure vessels.
This code provides comprehensive rules and guidelines for the design, material selection, fabrication, inspection, and proof-testing of thin-walled fusion-welded pressure vessels.
Compliance with this standard is mandatory for industrial equipment like retorts, heat exchangers, and autoclaves used in food processing.
Step 3: Final Answer:
The design and fabrication of pressure vessels is covered under IS 2825.
