ASTM A 213 T11 T22 U Bend Tube 25.4mm * 2.11mm For Evaporater Heat Exchanger

ASME SA213 T11 T22 U Bend Tube Heat Exchanger Tube 25.4mm * 2.11mm U Tube

U Bending Tube

As the both ends fixed on the same tube sheet, the shell and the tube are separated so the U-type heat exchange can not thermal expanse, and the tube bundle can free stretch out and draw back, and cannot produce temperature stress due to the fluid temperature difference. The U-shaped bend is adopting hydraulic drive, bend, PLC control and pipe clamp to complete automatically. The synchronization of the cantilever and elbow movement , effectively prevents pipe sag in the bending process and adjusts speed in the process of operation. Using encoder positioning can ensure the Angle is precise, and can be set freely. In the process of running, it can not only display the movement, but also can display an error message, to help correct the operation and debug troubles, in order to ensure the safety of the operator and device and put an end to the hidden trouble of the production.
