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 for corrosion resistance. Clear and accurate internal threads ensure tight assembly and reliable sealing. Every batch undergoes chemical composition inspection, thread tolerance testing and pressure test to meet international plumbing and gas fitting standards.

This series of 90° threaded elbows are designed for pipe direction change. They adopt internal thread connection method for fast installation without welding. The hot-dip galvanized layer provides stable rust protection in wet environment. Multiple standard sizes are available, and customized specifications can be produced according to buyer requirements. They can be matched with other malleable iron fittings including tees, couplings and reducers to form complete pipeline systems.

These malleable iron elbow castings are widely applied in water supply, natural gas, compressed air, fire protection and heating pipeline projects. Suitable for residential, commercial building and industrial workshop piping systems. As a professional casting procurement platform, we implement full-process quality control from raw material melting, casting forming, annealing to galvanizing inspection. We provide stable bulk supply and competitive pricing, satisfying large-scale procurement and OEM demands for global plumbing distributors and pipeline contractors.
