Heat Exchanger Tubes
Heat exchanger tubes are precision seamless or welded tubes used in shell-and-tube heat exchangers, condensers, evaporators, and feedwater heaters. They require excellent thermal conductivity, corrosion resistance, and tight dimensional control to ensure efficient heat transfer and long service life. Shree Raj Steels supplies heat exchanger tubes in stainless steel (304, 316L, 321, 347), alloy steel, and exotic materials including Inconel, Hastelloy, and Cupro-Nickel, conforming to ASTM A213, A249, and A269 standards.
Full material traceability & mill test certificates.
