Choosing the Correct Boiler and Heat Exchanger Tube

However, water tube boilers with curved tubes and U-tube exchangers (pronounced the same as YouTube) are also common. Unlike straight tubes, U-tubes do not exit at the opposite end, but rather curve back around and return to the front tube sheet. Curved tubes require a cleaning head that can work its way through the bend.
