ASME SB111 C68700 Aluminum Brass Seamless Tube u tube heat exchanger
This specification covers U-bend seamless condenser, evaporator, and heat exchanger tubes of copper and copper alloys up to 2 in., inclusive, in diameter. Tubes for this application are normally made from the following copper or copper alloys:
Copper Alloy Tube----Aluminum Brass Tube
Aluminum Brass Tube is a copper zinc alloy containing aluminum and small amount of arseric which is added as an inhibitor against dezincification. Inhibited Aluminum Brass resists the action of high velocity salt and brackish water and is commonly used for condenser tube.
The outstanding characteristic of Aluminum Brass is th high resistance to impringement attack.
Aluminum Brass tubes are highly accepted and one of the extensively used material for various industrial applications.
Product Range
• Outside diameter : 5.0 mm(min) ~ 65 mm(max)
• Wall thickness : 0.5mm(Min.)
• Length : 27,000mm(Max.)
• Product capacity per month : 500 M.T.
• U-bend tube (smallest bending radius ≥ 2 x tube O.D.)
Application :
Steam Ejector, Intor and After Condensers, Grand steam condensers, Feed Water Evaporators for Petrochemical, Ship-building, Power plants and Desalination plants etc.
