Products Description
Our Advantages
1. High-Temperature Resistance
- Our Inconel 617 pipe can operate reliably at temperatures exceeding 1000°C while maintaining its mechanical strength and creep resistance, making it ideal for gas turbine, reformer, and furnace applications.
- The pipes undergo high-temperature tensile testing to ensure stable operation in high-temperature applications.
2. Weldability
- Our Inconel 617 pipe offers excellent fabrication and weldability, a wide hot working temperature range (1200-950°C), and rapid cooling by water quenching. Rigorous mechanical testing and non-destructive testing ensure compliance with standards.
- The pipes have high ductility, making them easy to cut, bend, flare, and form, meeting the complex layout requirements of chemical, petrochemical, and power systems.
3. Dimensional Accuracy and Surface Quality
- Our pipes undergo rigorous dimensional inspection, with an outer diameter tolerance of ±0.05 mm.
- The pipes are treated with pickling, passivation, and polishing for high surface smoothness; electrolytic polishing treatment is also available, resulting in a surface roughness of Ra≤0.2μm.
4. Seamless Design
- Our pipes are seamless tubes manufactured using a cold drawing process, offering excellent compressive strength and suitability for high-temperature and high-pressure applications.
- The wall thickness is uniform without local thin spots, and the negative deviation of the wall thickness is strictly controlled according to ASTM B167 requirements to prevent local rupture.
5. Quality Control
- The pipes undergo rigorous chemical composition, dimensional inspection, intergranular corrosion testing, and mechanical performance testing to ensure compliance with ASTM B167 standards or customer requirements.
- The pipes are packaged with plastic end caps, plastic film, and wooden crates to prevent contamination during transportation.
