U bend steel pipe

Share:

In order to reduce the loss caused by the heat taken away by the cooling water in the condenser, feed water heating is used to reduce this loss, that is, after the high-pressure feed pump, high-pressure heater is added to improve the boiler feed water problem and economic benefit. Among them, the heat exchanger tube is an important core component, and the heat exchanger tube has a U-shaped tube. The U-shaped tubular heat exchanger is U-shaped without the heat exchange tube. Both ends are respectively fixed in the upper and lower areas of the same tube,sheet, and are divided into inlet and outlet chambers with the help of the diaphragm in the tube compartment. The heat exchanger completely eliminates the thermal stress and has a simpler structure than the floating head type, but the inside of the steel pipe is not easy to clean.
