Finned Tube
Produced by helically winding or welding metal fins (strips) onto the outer surface of a base tube. Features extended heat transfer surface area, high thermal efficiency, good mechanical strength, and durable fin-to-tube bonding.
Threaded Tube
Produced by cutting or rolling threads onto plain steel pipe ends (for coupling connections), or by cold rolling internal/external helical ribs along the tube length (for enhanced heat transfer). Features reliable mechanical connection (threaded ends), or improved heat exchange efficiency (helical ribs).
Aluminized Tube
Produced by hot-dip aluminizing of carbon or alloy steel tube, forming a continuous, intermetallic aluminum-iron alloy layer with an outer pure aluminum coating. Features excellent resistance to high-temperature oxidation, good corrosion resistance in sulfur-containing and high-temperature environments, and improved heat reflectivity.
Seamless Round Tube
Produced by piercing a solid billet and cold drawing or hot rolling without any weld seam. Features uniform structure, high pressure resistance, excellent dimensional accuracy, and good mechanical properties.
Shaped Tube
Produced by cold drawing, roll forming, or welding followed by reshaping processes to achieve non-standard cross-sectional profiles. Features precise dimensional tolerances, uniform wall thickness, good surface finish, and consistent mechanical properties.
Ductile iron pipe
Produced by centrifugal casting process using high-strength ductile cast iron, where graphite is spheroidized to enhance mechanical properties. Features excellent tensile strength, high impact resistance, good corrosion resistance, and superior ductility compared to gray cast iron. Available classes: K7, K8, K9, K10, K12, C25, C30, C40, C64 (ISO 2531), or Pressure Classes C20–C50 (EN 545). Diameter range: DN80 – DN2600mm (3″–102″).
Straight Seam Welded Pipe
Produced by forming steel coil or plate into a tubular shape and welding the longitudinal seam using high-frequency ERW (for small to medium diameters) or submerged arc welding LSAW (for large diameters).
Spiral Welded Pipe
Produced by helically forming steel coil into a tubular shape and welding the spiral seam using submerged arc welding (double-sided or single-sided). Features wide diameter range, good dimensional consistency, high strength, and cost-effective production for large diameters.
Galvanized Round Tube
Produced by welding or seamless forming followed by hot-dip galvanizing, which applies a uniform zinc coating for excellent corrosion resistance. Features smooth internal and external surfaces, good ductility, and strong coating adhesion.
