Petroleum parts steel castings

Our petroleum parts steel castings are professionally manufactured via precision investment casting and sand casting processes, specially engineered for the rigorous oil, gas and petroleum industry environments. Made from high‑grade carbon steel, alloy steel and stainless steel materials, these castings possess outstanding mechanical properties including high tensile strength, strong pressure resistance, superior corrosion resistance and excellent wear resistance, perfectly adapting to high‑pressure, high‑temperature, erosive and corrosive working conditions in oilfields, downhole operations and surface petroleum equipment.

We provide one‑stop customized services covering mold development, casting, heat treatment, precision machining and surface finishing. Each component undergoes strict non‑destructive testing, dimensional inspection and performance verification to ensure stable quality, reliable sealing and long service life. Widely applied in petroleum pumps, valves, wellhead fittings, drilling machinery, pipeline connectors and other critical petroleum equipment parts. Custom designs, sizes and material grades are available to meet diverse industry standards and project requirements.
