Investment Casting for Oil & Gas Equipment
Lantian Precision Machinery Manufacturing provides custom stainless steel, carbon steel and low alloy steel castings for oil and gas equipment manufacturers. As an experienced oil and gas equipment manufacturer supplier, we know exactly what is important for the oil & gas castings produced by investment casting process. We Lantian foundry manufacture complex components for valves, pumps, wellhead equipment, petroleum machinery and other demanding applications based on customer drawings, samples or 3D models.
Oil & Gas equipment often operates under demanding conditions involving:
- High pressure
- High temperature
- Corrosive fluids
- Abrasive media
- Continuous operation
- Strict dimensional requirements
These requirements make material selection, casting integrity, dimensional consistency and quality control important considerations when sourcing critical components.
Oil & Gas Components We Manufacture
Ball valve bodies castings
Gate valve bodies castings
Globe valve bodies castings
Check valve bodies castings
Other custom valve bodies castings
Wellhead & Oilfield Equipment Castings
We manufacture custom steel castings for selected oilfield and wellhead equipment applications, including housings, connectors, valve-related components and other engineered parts according to customer drawings and specifications.
- Pump housings castings
- Pump casings
- Impellers castings
- Pump Covers castings
- Connectors
- Other fluid-handling components
Downhole Equipment Castings
Selected downhole equipment components can be manufactured using custom investment casting when the part geometry, material and production requirements are suitable.
Material selection for oil and gas equipment casting components should be based on operating pressure, temperature, fluid characteristics, corrosion requirements, mechanical properties and applicable customer specifications.
Stainless steel is chosen for applications that call for high‑level corrosion resistance against harsh field media.
Carbon steel works well for general‑duty parts, delivering a good balance of strength, mechanical performance and cost‑effectiveness.
Low alloy steel is applied where specific mechanical properties, enhanced strength or reliable temperature‑resistant performance are required for critical oil‑gas service conditions.

Why Use Investment Casting for Oil & Gas Components?
1. Complex Geometry
Investment casting can produce complex shapes that may require multiple machining or fabrication operations when manufactured from solid material.
2. Near-Net-Shape Manufacturing
Sales material from waste by cnc machining.
3. Material Flexibility
- Stainless Steel
- Carbon Steel
- Low Alloy Steel
4.Dimensional Consistency
Repeat order is available and always has the same dimensions in tolerance.
5. Reduced Machining
Complex Component production reduced cnc machining work.
6. Design Flexibility
- Drawing
- Sample
- 3D Model
Drawing/sample → Engineering Review → Tooling → Prototype → Investment Casting → Heat Treatment → CNC Machining → Inspection → Delivery
