Product model and specifications

Material: HK40/HP-Nb/HP-Mod/35Cr45Ni; Outer diameter: 60 - 500mm; Wall thickness: 8 - 50mm; Operating temperature: ≤ 1100°C

Product Introduction

Specially designed for ethylene cracking furnaces and reformer tubes operating up to 1100°C. High Ni-Cr alloy composition provides excellent oxidation and carburization resistance. Centrifugal casting ensures dense, uniform wall preventing premature failure. Solution + aging heat treatment optimizes creep resistance. Custom bend radii and lengths available for specific furnace designs. Long-term high-temperature rupture data and full material traceability provided.
