U Bend Tube Manufacturing And Technology

 

Tolerances should be controlled conform to ASTM A688, standard, Special tolerances are available upon customer requirements.

Heat treatment should be done after U bend, heat treatment of bending portion may be required to reduce the residual stress, if not specified, heat treatment of bends plus minimum 150 mm of leg is standard.

U bend tubes should be fabricated as standard in high quality, controlling ovalization and thickness of bending portion accurately, and straightness of leg length, squareness and cleanliness of tube ends should be cut, to achive premium quality u bend tube, some factors and tests must be consided.

Stainless steel U bend tube is used in heat exchanger systems and other systems, it transfer heat from a hot to a cold side through the tube. This is made possible through the width of the tubes on each end, poor tube material can result in problems.
