Product Q&A

Q:What is the primary function of oil casing?

To support the wellbore walls, isolate formations, prevent blowouts, and establish a secure pathway for oil and gas extraction.

Q:How should one select the appropriate casing steel grade?

Selection depends on well depth, formation pressure, and corrosive environment. Common grades include N80 (general conditions), L80 (corrosive environments), and P110 (deep wells with high pressure).

Q:What is the difference between American Petroleum Institute threads and special threads?

American Petroleum Institute threads (e.g., STC, BC) offer cost-effective versatility; special threads provide superior sealing, tensile strength, and torsional resistance, suitable for high-pressure gas wells or complex well conditions.

Q:What key parameters are required when ordering casing?

Outer diameter, wall thickness, steel grade, thread type, length, and quantity. Specify whether American Petroleum Institute compliance is required.

Q:How to determine if casing quality meets standards?

Verify American Petroleum Institute certification marks and third-party inspection reports. Inspect physical markings, dimensional accuracy, thread machining quality, and non-destructive testing records.
