How far should tubes extend when rolled and expanded?

1/4", 1/2", 3/4"
1/2", 1/3", 1"
3/4", 1", 2"
1/8", 1/4", 1/2"

The correct answer is: 1/4", 1/2", 3/4"

The appropriate extension of tubes when rolled and expanded is critical to maintaining the integrity and efficiency of the boiler system. When tubes are rolled and expanded, they must securely fit within their respective headers to prevent leaks and ensure proper heat transfer. The correct selection indicates that the tubes should extend by specific dimensions that strike a balance between providing secure engagement in the header while preventing excessive material stress. A measurement of 1/4", 1/2", or 3/4" reflects common industry standards that ensure a proper seal without compromising the structural integrity of the tubes. Choosing other options would either suggest extensions that are too short, risking inadequate sealing issues, or too long, which could lead to compromised structural strength or difficulty in installation. Therefore, the identified measurements align with standard practices in low-pressure boiler operations, ensuring both safety and efficiency.
