FAQ

IF YOU HAVE OTHER QUESTION,PLEASE CONTACT US!

Q: What is the primary function of oil casing?
A: 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?
A: 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?
A: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?
A: 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?
A: Verify American Petroleum Institute certification marks and third-party inspection reports. Inspect physical markings, dimensional accuracy, thread machining quality, and non-destructive testing records.
