Quenos at Altona, Victoria runs a polymerisation plant. The main process is a high severity ethylene pyrolysis furnace. Material used in the furnace is Incoloy alloy 803 (UNS S 350045). This alloy provides an exceptional level of high temperature corrosion resistance in oxidation, sulfidation and carburisation environments along with excellent stress - rupture strengths at elevated temperatures. The tubing internally finned to increase turbulence inside the tube and enhance heat transfer in the furnace tubes (dia 51 x 7mm). U-Neek manufactured all 8 banks of the furnace, complete with tube bending, critical welding of tubes to heaters, header flange welding, hydrotesting of equipment, complete NDT and MDR provided.
