Overview
Basic parameters of U-shaped tube heat exchanger (1) nominal diameter DN/mm
Product Details
U-shapedtube heat exchangerThe basic characteristic of the tube is that there is only one tube plate, and the bundle is composed of multiple U-shaped tubes. The two ends of the tubes are fixed on the same tube plate, and the tubes can expand and contract freely. When there is a difference between the shell and the U-shaped heat exchange tube, no thermal stress will be generated.
