Stainless steel U bend tube are used in heat exchanger systems, as boiler tube, condensers, exhaustion tube and other systems, it transfers 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, DONGSHANG STAINLESS produce U bending tube complying with specifications, like A213, A249, A688, strictly inspect from material to final product, making U bending tubes 100% high quality.
