ASTM B111 C44300 Admiralty Brass U Bend Tube
Product Introduction
ASTM B111 C44300 U Bend Tube is manufactured from UNS C44300 Admiralty Brass, a copper-zinc alloy traditionally used in condenser and heat-transfer tubing.
The U-bend configuration allows two straight tube legs to be connected through a controlled-radius bend, making the tube suitable for compact tube bundles where a return bend is required. Compared with assembling straight tubes with separate return fittings, a U-bend tube provides a continuous tube length through the bend.
C44300 is commonly associated with condensers, marine heat-transfer equipment and water-cooled systems, particularly where the tube side is exposed to freshwater or seawater-related service.

Product Advantages
C44300 is an Admiralty Brass alloy containing copper, zinc and a small tin addition, traditionally used for condenser and heat-transfer tubing.
The tube is bent to a specified centerline radius and leg length, allowing the U-tube bundle to accommodate thermal expansion within the exchanger.
The bend is formed from the tube itself, eliminating a separate return fitting at the U-shaped end.
C44300 tubing is commonly associated with condenser and marine heat-transfer applications where water-side corrosion considerations are important.
Bend radius, straight-leg length, tube OD and wall thickness can be produced according to exchanger drawings or project specifications.
