Factories specializing in malleable iron galvanized pipe fittings follow meticulous manufacturing protocols to ensure product quality. The primary raw material, malleable iron, is obtained through the casting process, wherein iron is melted and poured into molds. After cooling, the castings undergo a heat treatment process, typically annealing, to improve ductility and strength. The ability to bend and shape malleable iron without breaking makes it a preferred material for pipe fittings.
