Seamless precision tubes are produced using the cold drawn process. It can be supplied as cut tubes and bent tubes. Cut tubes are designed especially for manufacturers of automotive components.Precision steel tubes from our production satisfy the requirements for the following applications: components for the vehicle drivetrain, cars and motorcycle suspension systems, components for body and chassis, vehicle control systems and others.
ASTM A179 heat exchanger tubes A 179 Standard Specification for Seamless Cold-Drawn Low-Carbon Steel Heat-Exchanger and Condenser Tubes This specification covers minimum-wall-thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus. This specification covers tubes 1/8 to 3 in. [3.2 to 76.2 mm], inclusive, in outside diameter.
--Precise custom outer diameter and inner diameter --Tight tolerances, resulting in reduced machine time / Dimensional accuracy --Smooth and Clean OD and ID surfaces --Excellent machining characteristics --Wider range of physical properties attainable through process and annealing options
