High Quality Casting Services for Oilfield Well Drilling Pump Housing Product

Robust Engineering for Demanding Oilfield Applications
Our specialized casting services deliver premium-quality pump housings specifically engineered for the extreme demands of oilfield well drilling operations. These critical components are manufactured to withstand high-pressure cycling, abrasive drilling fluids, and continuous operation in the world's most challenging drilling environments, ensuring reliability when performance matters most.

Advanced Material Technology
We employ high-strength alloy steels and specialized irons developed for oilfield service:

• ASTM A487 Grade 4N: High-strength low-alloy steel with superior yield strength (550-750 MPa)

• Ductile Iron 80-55-06: Delivering optimal strength-to-weight ratio with excellent impact resistance

• Stainless Steel CF8M: Providing exceptional corrosion resistance in sour gas environments

• White Iron Ni-Hard 4: Offering maximum abrasion resistance for slurry service
  All materials include full traceability and certification to API 6A/ISO 11960 standards, with Charpy V-notch testing at -40°C for arctic applications.

Enhanced Performance Characteristics
