U Bend/Return Bendsare formed by By thermoforming process with a very small bend radius which bend radius smaller than 1.5 tube out diameter(R≤1.5D). Such Return bend tube help save much installation space,widely application to Economizer,Boilers, Heat exchangers,tube bundles,Radiators, air coolers, air preheaters etc. All of our return bends and tube fabrications are manufactured to the customer’s specifications.U Bend/Return Bend under the stringent quality checks before the delivery to ensure quality is served to our valued customers.
