What is the minimum allowed corner radius for a vessel insert plate?

• A. 1"
• B. 2"
• C. 3"
• D. 6"

Answer: (A)

The minimum allowed corner radius for a vessel insert plate is 1 inch. This requirement is established to ensure structural integrity and proper stress distribution around corners of the insert, which are critical in pressure vessels. Sharp corners can lead to stress concentration, which increases the risk of crack formation and eventual failure of the vessel under pressure. Having a minimum corner radius helps to mitigate these risks by allowing for a more gradual transition between the surfaces of the insert and the vessel, which enhances the overall durability and compliance with safety standards. In vessel design, proper corner radii are crucial for ensuring that the vessel maintains its integrity throughout its operational life, particularly at points where significant stress may be concentrated. In practice, adherence to the 1-inch minimum radius facilitates easier fabrication and welding processes while reducing the likelihood of issues related to fatigue and corrosion at critical junctions within the pressure vessel system.
