Tube Expanding Ratio For Boiler Tubes

What are the various types of tubes used in water tube

In the majority of cases boiler tubes are expanded, and then bell-mouthed into drums or headers. For large diameter tubes, such as downcomers, grooved seats are used to assist the expansion in forming a tight seal. Where high temperatures are involved, as with superheater tubes, welding may be used in place of expanding. Tubes Attachments

For larger boilers, it is best to cut all tubes approximately 3/4" to 1" longer than required. Insert the tubes in the tube holes and set them uniformly at one end, preferably the back end of the boiler, so that the ends of the tubes project 3/16" to 1/4" beyond the face of the tube sheet for the beading operation.
