U-BENDING / U bend Tubing / U Tube:
U-BENDING / U bend Tubing / U Tube heat exchangers comprise a U shaped tube fixed by flow baffles or tubes supports and placed in shell to control the fluid present in the exterior of the tube assembly. The fluid is guided into the tubes by a head assembly, which is fixed to the shell by bolts.
Bending Radius: From 1.5 * O.D (outside diameter) ,When ordering tubes with bending radius less than 1.5*OD, it is necessary to get the agreement with us.
Straight tubes maximum length (before bending): 35000 mm.
Leg length: min 1 meter, max. 16500 mm (for max r=1500mm)
Note: Other sizes are available upon agreement.
Heat treatment: stress relieved after u-bending (bending area plus 300mm for each leg).
