What type of joint efficiency is allowed for a full encirclement lap band?

• A. 0.65
• B. 0.75
• C. 0.85
• D. 0.95

Answer: (C)

For a full encirclement lap band, a joint efficiency of 0.85 is allowed. This rating reflects the strength and reliability of the joint formed by the lap band around the pressure vessel. The full encirclement lap band is used to reinforce the vessel and is designed to improve its structural integrity, especially in regions that might be subject to high stress or potential failure. The joint efficiency value of 0.85 reflects a high level of confidence in the integrity of the lap band joint due to the quality of the weld and the design of the banding. In practice, full encirclement lap bands undergo stringent inspection and testing to ensure they meet safety and performance standards, which further justify the higher joint efficiency rating. The remaining options reflect lower efficiency ratings typically associated with other types of welds or joint designs that do not have the same reinforcing capabilities, thereby providing assurance that the chosen answer aligns with established standards for pressure vessel inspections.
