BRIEF HISTORY OF WATER-TUBE BOILERS 1 -

2007-9-18 · Another form of water tube was patented in 1805 by John Cox Stevens, a son of John Stevens. This boiler consisted of twenty vertical tubes, 1¼ inches internal diameter and 40½ inches long, arranged in a circle, the outside diameter of which was approximately 12 inches, connecting a water chamber at the bottom with a steam chamber at the top.

Best Practices For Expanding Water-Tube Boiler Tubes

What is the tube sheet thickness, drum thickness, or length of the tube? Do the tubes have a bend outside of the drum? For drums that are 18" in diameter or larger, it's recommended that a regular or drum mandrel be used. A series of short mandrels would be used in bent tube boilers, to prevent the mandrel from damaging the tube.
