TONGJI-INTEGRAL LOW FIN TUBE is available for a wider range of alloys than traditional low-fin tubing which is restricted to soft metals. Such as Titanium , Nickel Alloy, Duplex Steel.
The integral low fin tubes are from extruded seamless tubes on outside surface only or outside and inside surface for double enhanced performance.
