Nickel Pig Iron is produced from low-grade nickel ore (laterite ores), coking coal, and a mixture of fluxes. The Nickel Iron ore fines are blended and calcined in the sinter plant to remove moisture and provide pellets as feedstock for the blast furnace. Sinter pellets, lump nickel iron ore, coke and fluxes are then loaded into the hot air blast furnace where Ferro Nickel oxides are reduced into Nickel Pig Iron. Impurities and slags are then removed from the reduced nickel iron melt before the molten nickel-iron is cast into the pig-molds forming the Nickel Pig Iron.

Billets
Raw materials used for billet production are scrap metal sourced from neighboring provinces in the southern Philippines (Visayas and Mindanao regions), through its own collection network or major scrap consolidators and pig iron, a semi-finished metal produced from iron ore in blast furnace, containing 80-92 percent iron, high amounts of carbon (typically up to 3.5 percent), and balance largely manganese and silicone plus small amounts of phosphorus, sulfur, and other impurities. Pig iron is further refined in a furnace for conversion into steel..
Steel Pipes
Electric Resistance Welded (ERW) Pipes Electric Resistance Welded (ERW) pipes are produced from hot rolled steel strips or skelp. They are rolled into respective sizes and welded longitudinally. ERW pipes are used for general construction applications such as plumbing, water transmission, scaffolding and fencing.
Spiral Welded Pipes Spiral Welded Pipes are produced from hot rolled steel strips spirally roll-formed into respective sizes and welded along the edge of the strip. They are used for general construction applications where large diameter pipes are needed , e.g., piling, bulk water transmission, etc.
Seamless Pipes Seamless pipes are produced from billets through a hot draw and extrusion process. They are used for high pressure applications in oil field development and oil production, high temperature applications..
Electric Resistance Welding Machine with Stretched Reduced Mill (ERW-SRM) Pipes ERW-SRM pipes are essentially produced using the ERW process. The pipes are then subjected to tension and reduction forces under moderate temperature conditions to produce virtually seamless pipes.
ERW-SRM pipes are used for medium pressure applications for oil wells, boiler pipes, fluid and gas transmission.
