High Temperature Nickel Alloy Seamless Pipe DN 76x3 mm HN78T XH78T KHN78T TU 14-3-520-76
This grade HN78T XH78T is manufactured with a help of open-type remelt method. This alloy is widely used in industries for manufacturing floating details that are exploited at a temperature range of 1000−1100°C (f. e. in manufacturing of flame tubes, thermocouple cases, combustion chambers etc.) International analogous grades of alloy are marked as 2.4951NiCr20Ti (Germany), GH3030 (PR China). Alloy has main types of mill-products: tube, wire, strip, sheet, rod. Due to high nickel content, it relates to a group of heat-resisting materials. Its main demerit is non-stability to environments that contain sulphur. It causes a brittle behavior. Its oxidation rate is 0,2 mm/h up to a temperature of 1100 °C.

| 5. Packing | *All of our nickel alloy seamless pipes and tubes are packaged according to international standards to prevent any possible damage or loss. By default, we will use thick woven plastic bags to bundle the finished pipes together in batches. For some special pipes and tubes that are vulnerable to dirt, scratches, stress, or rough handling, we will suggest using wooden cases for protection. Please note that wooden cases may incur extra costs not only for the case itself but also for increased freight costs, especially when using air transportation. To enhance customer experience, we also provide dedicated packaging according to your specific requirements." |
