Our malleable cast iron threaded elbow castings, also known as malleable iron pipe fittings, are widely used 90-degree pipeline connection components for low-pressure fluid delivery. Made of high-quality malleable cast iron by precision casting and annealing treatment, these elbow castings have good toughness, high tensile strength and excellent anti-fracture performance, solving the brittleness problem of ordinary cast iron. After casting, the parts can be hot-dip galvanized
