The products are also exported to 38 countries including the United States, the United Kingdom, Germany, Canada, Japan, Turkey, Russia, India, South Korea, etc.

NH1949 Anti-coking New Material

Anti coking: Extends decoking cycle by 2-5 times, reducing decoking frequency.

Anti-Oxidation: Fully oxidation-resistant at 1200°C, extends furnace tube service life by 1.5-2 times.

NH25-35GR Long-life New Material

Withstands operating temperatures up to 1100°C.

Effectively extends furnace tube service life.

Reduces fuel consumption and increases production.

NH2749 High-temperature Resistant New Material

Suitable for high-temperature condition above 1185°C with excellent oxidation resistance and high-temperature performance. Offers higher creep strength.

NH2829 Cost-effective New Material

Features excellent overall performance, stable long-term microstructure and properties. Tensile strength and room-temperature yield strength are superior to Cr28Ni48W5 alloy.

3D Digital Bending Tubes

Reduces coking on furnace tubes: Weld seams are eliminated or root-cleaned neatly, solving coking issues caused by ungroomed weld roots at U-bend and S-bend connections.

Thin-Walled Radiant Tubes

High heat-transfer efficiency.

Rapid heating.

Excellent thermal-fatigue resistance.
