Oil casing pipe thread processing technology and equipment

Processing Process Flow

- Preparation of Raw Materials

Select high-quality steel billets.

Conduct chemical composition and mechanical performance testing to ensure the raw materials meet the standards.

- Heat Treatment

Heat the steel billets, maintain the temperature, and then cool them to improve their internal structure and mechanical properties.

- Turning Processing

Use a lathe to turn the outer diameter and inner hole of the heat-treated steel billet to achieve the specified dimensional accuracy and surface roughness.

- Thread Processing

Utilize a specialized threading machine to process the threads on the turned casing, including cutting, trimming, and inspection.

- Cleaning and Rust Prevention

Clean the processed casing to remove surface oil and impurities.

Apply anti-rust oil to prevent corrosion.
