Wrong Statement: c) A butt joint with two cover plates should be used for circumferential joint in boilers.

Explanation:
A butt joint is a type of joint where two plates are joined together by overlapping their edges and then joining them using rivets or other fasteners. A circumferential joint, on the other hand, refers to a joint that runs along the circumference of a cylindrical structure, such as a boiler.

Butt Joint with Two Cover Plates:
In the case of a circumferential joint in boilers, a butt joint with two cover plates is not typically used. This is because a butt joint with two cover plates would result in excessive thickness and weight, which is not desirable for boilers.

Alternative Joint for Circumferential Joint in Boilers:
The preferred joint for a circumferential joint in boilers is a lap joint. A lap joint involves overlapping the edges of the plates and then joining them using rivets or other fasteners. This type of joint provides sufficient strength and durability while minimizing the thickness and weight of the joint.

Advantages of Lap Joint:
1. Weight Reduction: A lap joint with a single cover strap reduces the overall weight of the joint compared to a butt joint with two cover plates.
2. Ease of Installation: A lap joint is relatively easier to install compared to a butt joint with two cover plates.
3. Cost Savings: Using a lap joint instead of a butt joint with two cover plates can result in cost savings due to reduced material and labor requirements.

Conclusion:
In summary, the wrong statement is c) A butt joint with two cover plates should be used for a circumferential joint in boilers. Instead, a lap joint with a single cover strap is typically used for circumferential joints in boilers due to its advantages of weight reduction, ease of installation, and cost savings.
