Castings for petroleum machinery

Our petroleum machinery castings are precision‑manufactured via investment casting process, adopting high‑grade carbon steel, alloy steel, stainless steel and special anti‑corrosion materials like 13Cr L80.

Designed for harsh oilfield and downhole working conditions, these castings feature high pressure resistance, wear resistance, corrosion resistance and stable mechanical performance. Strict dimensional control and fine surface finish ensure perfect assembly for oil pipes, couplings, pump parts, valve components and other core petroleum machinery parts.

Customized sizes and specifications are available to meet diverse industry standards and customer requirements, widely used in onshore and offshore oil & gas extraction equipment.
