Shell-and-tube heat exchanger bundle for a South American industrial facility.
ASTM A192 is the specification for seamless carbon-steel boiler tubes intended for high-pressure service. Its tight dimensional tolerances and controlled surface finish make it the preferred choice for shell-and-tube heat exchanger construction, where uniform wall thickness is essential for consistent heat-transfer coefficients and tube-to-tubesheet expansion.
Cold-drawing — the manufacturing step that distinguishes A192 from hot-finished tube — achieves tight OD and wall tolerances, a smooth bore that reduces fouling, and enhanced mechanical properties through work hardening. The clear-varnish finish on this supply protects the clean cold-drawn surface during ocean transit and storage before bundle assembly, avoiding rust that would require mechanical cleaning prior to expansion.
Plain ends with fitted protective caps prevent thread damage and bore contamination during shipping. The 25-ft (7.62 m) cut length matches the shell length of the client's standard heat exchanger design.
ZC Steel Pipe supplies ASTM A192, A210, and A213 boiler and heat exchanger tubes to industrial clients in South America, the Middle East, and Southeast Asia. Dimensional inspection and hydrostatic test certificates are supplied as standard.
