ASTM B163 Monel 400 U bend seamless stainless steel tube coil tubing 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.

Application: Boiler tube applies to petroleum, chemical industry, electric power, boiler, high temperature resistant, low temperature resistant, corrosion-resistant. The size can be made according to the customer's requirements. A high-pressure boiler pipe applies to the container, petrochemical, and so on. Note: Generally, high-pressure boiler pipe’s working pressure above 9.88Mpa and working temperature between 450 to 650.
