U- BENDING

U- BENDING U- TUBE HEAT EXCHANGERS COMPRISE A U- SHAPED TUBE FIXED BY FLOW BAFFLES OR TUBES SUPPORTS AND PLACED IN A 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 od( outside diameter) to 1500mm

When ordering tubes with bending radius less than 1.5 OD, it is necessary to get the agreement with seller

Straight tubes maximum length( before bending) 35000 mm.

Leg length: min 1 meter, max.

16500 mm ( for max r=1500mm)

Note: other size are available upon agreement.

Heat treatment: stress relieved after u- bending ( bending area plus 300mm for each leg) .

packaging In strong transport- worthy pre- fumigated wooden boxes of corresponding dimensions for each tube length, radius, diameter, according to po requirements as well as wrapped in polyethylene films with soft plastic caps on both end of tube

TEST & INSPECTION PLAN
