Power Generation
With the boom in power generation infrastructure development in South Africa (which has included the demothballing of three coal-fired power stations), Steloy has been playing a key role in the supply of critical components for heat, wear and corrosion resistant applications, particularly in the generation and handling of steam.
Components for boilers and heaters range from furnace tubes, burners and grids to pump casings, housings and impellers, while the main components for the handling of steam are valve bodies, pump casings, bodies and impellers, primarily for condensate management.
Typical cast components and their material specifications are:
- Burner nozzles, cast in heat resistant Cr-Ni alloys such as ASTM A297
- Furnace tubes, in heat resistant Cr-Ni alloys such as ASTM A608 HK40
- Wear resistant grids, in BS 3100 gr.BW 3
- Pump casings, in stainless steel CF8M according to ASTM A734
- Pump impellers, in stainless steel (17-4PH ) ASTM A747 CB7Cu-1
- Valve Bodies, in Cr-Mo Steel ASTM A217 WC9, and
- General engineering components in Nodular Iron and Flake Graphite Irons.
