Custom Heavy-Duty Castings – Gray Iron, Ductile Iron & Carbon Steel Parts with Precision Machining, Suitable for Turbines, Pumps & Pressure Vessels
| Supply Capacity: | 1000tons per month |
We specialize in manufacturing large-scale industrial castings, including cylindrical housings, flange rings, pressure vessel shells, and turbine components, made from gray iron, ductile iron, and carbon steel. With advanced resin sand casting and Iron Mold with Shell Sand Process, we produce high-strength, dimensionally accurate parts weighing up to 5 metric tons, ideal for demanding applications in wind energy, mining, power generation, and heavy machinery.
Our products feature:
- Robust structural design: Reinforced ribs and thick walls ensure excellent load-bearing capacity and vibration resistance.
- High-precision flanges: Equipped with stainless steel or alloy steel cladding for enhanced sealing performance and corrosion resistance.
- Surface protection: Coated with durable epoxy paint (blue, white, gray) for long-term outdoor use in harsh environments.
- Standardized interfaces: Multiple bolt holes with red sealant marks for quick assembly and alignment.
Key materials:
- Gray Iron (HT250/HT300): Excellent wear resistance and machinability, suitable for pump casings and housing.
- Ductile Iron (QT400-18/QT600-3): High tensile strength and impact resistance—ideal for rotating equipment and dynamic loads.
- Carbon Steel (ZG270-500/WCB): Used for high-pressure or high-temperature applications such as valves and reactors.
All castings undergo strict quality control, including spectroscopic analysis, tensile testing, and non-destructive inspection (UT/MT). We provide full documentation, including Material Test Reports (MTRs) and dimensional inspection certificates.
Applications include:
- Wind turbine nacelle covers & hub flanges
- Pump housings and motor end shields
- Reactor vessels and pressure tanks
- Mining crushers and conveyor components
- Marine and offshore equipment
