Expert FAQ: All About Casing Pipe Technology

Q: What are the main material grades available for well casing pipe for sale?
A: API 5CT standard grades include J55 (general), K55 (higher yield strength), N80-1 and N80-Q (improved impact resistance), and L80 (superior corrosion resistance).
Q: What does “BTC” connection mean in casing pipe?
A: BTC stands for “Buttress Thread Coupling,” a robust API thread form providing high axial strength, preferred for deeper wells and challenging environments.
Q: How is wall thickness chosen for oil or casing pipe for borewell?
A: Wall thickness is selected based on borehole depth, expected formation pressure, and corrosion factors. Common thickness for 5 1/2” casing is 7.72mm, 8.56mm, or 10.54mm.
Q: What manufacturing standards apply to your casing & tubing pipe?
A: Products comply with API 5CT, API 5B threading, and ISO11960, with rigorous mechanical tests and non-destructive evaluations.
Q: What are the installation standards for modern casing pipe?
A: Installations follow API RP5C1 and ISO14310 best practices to ensure leakproof joints, vertical alignment, and safe load transfer to cemented annulus.
Q: Is customization available for length, thread, or coating?
A: Yes, customers can specify R1, R2, R3 lengths, connection types (BTC, LTC, STC), or advanced coatings for corrosion.
Q: What is the difference between production tubing and casing pipe?
A: Casing pipe forms the permanent well wall, while tubing carries oil/gas to the surface in production operations.

Key Advantages of API 5CT Casing & Tubing Pipe

Pressure Handling: Withstands formation and surface pressure cycles up to and above 70 MPa depending on grade and thickness.
Corrosion Resistance: Select grades (e.g., L80) feature chromium and molybdenum content, supporting long service in sour (H₂S) and CO₂ environments.
Connection Integrity: API standardized threads (BTC, LTC, STC) with optimized makeup torque guard against leakage.
Exacting Tolerances: Manufactured with tight ovality, straightness, and length tolerances, verified via ultrasonic and hydrostatic inspection.
Traceability: Full MTCs (Mill Test Certificates) provided for each batch.

Case Study: Deployment of 5 1/2 casing pipe for sale

In a 2023 Middle East oil project, Beijing Sinoworld’s 5 1/2" L80 BTC casing pipe was deployed at 3,400m total depth. Field engineers noted zero thread galling, outstanding collapse resistance, and high-performance cementation during wireline logging. These results demonstrate our commitment to API, ISO and project-specific quality standards.

How to Select the Right Casing Pipe for Sale

Determine required outer diameter (OD) and wall thickness as per formation and flow needs.
Choose steel grade based on downhole corrosivity, operating pressure & temperature (J55 for standard, L80 for sour gas wells, etc).
Decide on thread connection: BTC for high-load, LTC/STC for specific casing programs.
Confirm QA/QC documentation – look for API certificates and Mill Test Certificates.
Request references and case studies for similar applications.
