All incoming raw materials are strictly inspected for chemical composition, mechanical properties, and surface quality to ensure compliance with relevant standards and project requirements.

Approved suppliers are evaluated regularly. Each batch of materials is traceable through unique identification codes, ensuring full lifecycle quality tracking.

During manufacturing, critical processes such as forging, machining, heat treatment, and assembly are continuously monitored to ensure dimensional accuracy and process stability.

Key components undergo controlled heat treatment processes to achieve required hardness, strength, and durability. Performance is verified through standardized testing.

Critical parts are inspected using non-destructive testing methods such as ultrasonic testing, magnetic particle inspection, or dye penetrant testing to detect internal and surface defects.

All finished components are checked for dimensional tolerances, surface finish, and overall appearance to ensure they meet design specifications.

For applicable products (such as pumps and assemblies), functional testing and pressure testing are conducted to ensure reliable performance under real operating conditions.

Surface treatments such as coating, plating, or anti-corrosion processes are inspected to ensure durability in harsh oilfield environments.

Before shipment, a comprehensive final inspection is conducted. All inspection reports, certificates, and quality documents are reviewed and archived.

Products are securely packaged according to export standards to prevent damage during transportation. Packaging is inspected before shipment.
