The product is a seamless tube made from Incoloy 600/800 nickel‑chromium‑iron alloy. It conforms to ASTM B163, B165, B167 and B407 specifications. The alloy offers oxidation and corrosion resistance up to 1100 °C. ARK Steel Tube Company supplies the tubes in a range of outside diameters and wall thicknesses suitable for industrial piping.
Incoloy 600 and 800 are standard grades widely recognised for high‑temperature service in petrochemical and power generation sectors. Typical commercial tubes are produced with a tolerance of ±0.2 mm on diameter and ±0.1 mm on wall thickness, meeting the typical dimensional limits of the ASTM standards. The seamless manufacturing process eliminates weld defects, providing a consistent microstructure that enhances fatigue resistance. These characteristics align with the standard expectations for nickel‑alloy tubing used in heat exchangers and furnace components.
Major buyers include refinery operators, chemical plant engineers and OEMs designing heat‑treatment equipment. Orders are normally shipped in bulk crates with protective padding, and the supplier can arrange FOB or CIF terms upon request. Prospective importers should confirm the exact size schedule, required certification and payment conditions directly with ARK Steel Tube Company.

Before placing an order, verify the exact size schedule, material grade and any required certifications such as a mill test report or third‑party assay. Request a sample cut or a recent test certificate to confirm that the alloy composition matches Incoloy 600 or 800 as specified.
Logistics should be clarified early: discuss whether the shipment will be FOB from the port of Shanghai or CIF to the destination port, and confirm container loading plans, crate dimensions and any special handling needed for long tubes. Payment terms are not disclosed in the listing, so negotiate a suitable arrangement, for example a letter of credit or advance payment, after agreeing on the trade terms.
Upon receipt, perform a visual inspection for surface defects and arrange ultrasonic testing to verify wall thickness consistency. Compare the results with the supplier‑provided specifications and retain the mill test report for quality assurance and customs clearance. Confirm that all required import permits and material safety data sheets are available for the nickel‑alloy product.
