Stainless Steel U Bend Tube Low CI - Corrosive Resistance Polished Surface

Stainless Steel U Bend Tube ASME SA213/ SA213M -2017 TP316 TP316L TP304L OD 25.4mm 19.05mm 100% ET / HT

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.
