ASTM A214 Steel Pipe

At the forefront of ASTM A214 steel tubes is their unique design that combines functionality and durability. These tubes, primarily known for their electric-resistance-welded, carbon steel composition, are pivotal for heat exchangers, condensers, and various other heat-transfer applications. The sturdy material and precise manufacturing process ensure that they provide a seamless experience, literally and figuratively, for all heat transfer needs.

ASTM A214 Specification

At UNIACERO, our A214 tubes stand as a testament to precision and durability. They range up to 3 in. [76.2 mm] in outside diameter. However, should you have unique needs, we’re adept at crafting tubes of different dimensions while still adhering to the robust standards of this specification. As you specify the desired outside diameter and minimum wall thickness, rest assured that the inside diameter remains optimal. Both inch-pound and SI units are employed, offering you flexibility and adherence to specific requirements.
