    Carbon Steel Seamless Tube G Type Fin Tubes Embedded Fins Heat Exchanger Pipe

    Carbon Steel Seamless Tube G-Type Embedded Fin Heat Exchanger Pipe

    Material

    This product is a seamless, cold‐drawn carbon steel heat‐exchanger tube with embedded “G-Type” fins mechanically formed into the outer wall of the base tube. The fins (typically aluminium, copper or steel) are secured in deep machined grooves in the parent tube wall to provide enhanced surface area and heat‐transfer performance.

    Specification

    • Base tube: seamless cold‐drawn carbon steel tube (e.g. to specification ASTM A179 / ASME SA179)

    • Fin Type: G‐Type Embedded (grooved and back‐filled fin strip)

    • Typical outer diameter range: ~ 16–63 mm (0.63″–2.5″) for base tube; fin height and fin pitch vary depending on the design.

    • Typical fin height: up to ~ 19 mm, fin thickness ~0.4 mm for G-type fin tube.

    • Tube length: up to ~15 m (≤ 15 m) typical in this design.

    Key Features

    • The embedded fin construction secures the fin strip in a mechanical groove in the base tube, ensuring strong fin adhesion, minimal fin detachment, and excellent stability under thermal cycling.

    • Increased effective outside surface area compared to bare tubes — thereby improving external heat-transfer coefficient when the outside fluid (often air or gas) has low h-value.

    • The G‐type fin tube enables high heat‐transfer efficiency in applications where heat is transferred from a fluid inside the tube to a gas/air outside (or vice-versa) and the tube outside coefficient dominates.

    • Good suitability for moderate temperature service (e.g., up to ~400 °C for certain fin tube configurations).

    Our Advantages

    From a factory viewpoint, we address customer‐concerns and provide assured performance across these typical questions:

    Customer ConcernOur Response / Advantage
    Straightness / RunoutWe implement precision cold-drawn seamless base tubes, followed by consistent fin-embedding groove-rolling and straightening operations. The result is minimal geometric deviation and stable fin alignment.
    Wall‐thickness tolerance & base‐tube integrity under fin groove‐machiningOur base tubes are produced to tight tolerance (cold-drawn) and we control groove machining to ensure minimal reduction of wall cross‐section, maintaining sufficient residual wall thickness for pressure/thermal loads.
    Fin attachment durability under thermal cycling / vibrationUsing mechanical embedment (grooved and back‐filled) rather than welded fins, our G-type fin tubes avoid fin weld fatigue, promote strong fin anchoring and reduce the risk of fin detachment in service.
    Heat-transfer performance reproducibilityWe offer customizable fin height, fin pitch and fin thickness options; our quality control includes dimensional verification (fin height, pitch) and surface finish checks to ensure that the designed enhanced surface area is achieved reliably.
    Manufacturing traceability & material certificationAll tubes are supplied with full chemical analysis (heat + product), mechanical testing (tensile, yield, elongation, hardness), flattening/flaring/hydrostatic tests as required by the standard. This ensures full traceability and compliance.

    Applicable Standards

    • Chemical & mechanical requirements: ASTM A179/A179M (also referenced as ASME SA179/SA179M)

    • Manufacture: seamless cold‐drawn tubes for heat‐exchanger and condenser use.

    • Dimensions: Outside diameter 1/8″-3″ (3.2 mm-76.2 mm) inclusive; minimum wall thickness per specification.

    Application Areas

    General application field: industrial heat-exchanger systems (including condensers, air-coolers, gas coolers, waste-heat recovery units)
    Specific use cases in that field:

    • In air-cooled heat-exchanger units, the embedded fin tubes serve as the tube bundle over which ambient air flows across the fins, improving cooling of process fluid inside the tube.

    • In steam or hot-gas condensers, the finned tubes provide enhanced outer surface for condensing vapour on the outside (or absorbing cooling air) while fluid flows within the base tube.

    • In petrochemical cracker waste-heat recovery, the fin tube enables compact design by replacing multiple bare tubes with fewer fin tubes (because of higher heat-transfer coefficient).

    • In power-plant condenser systems, the fin tube may be used in economizers or auxiliary cooler bundles where external gas side coefficient is low (e.g., flue-gas side).
