| High Light | API 5CT Oil Tubing Pipe ，API 5CT OCTG Tubing | ||
Oil tubing pipe is a critical component in oil and gas well completion. After drilling is finished and the well is cased, tubing is run inside the casing to serve as the conduit that transports crude oil and natural gas from the reservoir to the surface. Tubing must withstand the pressures generated during production, as well as tensile loads, corrosive fluids, and temperature extremes. Unlike casing — which stabilizes the wellbore — tubing is the actual artery through which hydrocarbons flow to surface facilities for processing.
API 5CT tubing is classified into three main connection types:
|
Type |
Full Name |
Description |
|
NU |
Non-upset tubing |
The pipe ends are not thickened; threads are cut directly into the pipe body. Lower cost, suitable for less demanding applications. |
|
EU |
External upset tubing |
The pipe ends are thickened (upset) externally before threading, providing greater joint strength. Most common for production tubing. |
|
IJ |
Integral joint tubing |
The box threads are cut directly into the pipe body without a separate coupling. Provides maximum clearance for tight-hole applications. |

|
C90 / T95 |
90,000 / 95,000 |
Dedicated sour service grades for higher-strength applications in H₂S environments. Grain size finer than ASTM 5, with strict hardness limitations. |
|
P110 |
110,000 |
High-strength grade for deep wells and high-pressure environments. General use in demanding completions. |
|
V150 |
150,000 |
Ultra-high-strength grade for extremely deep wells and the most severe load conditions.- |
|
13Cr-80/110 |
80,000 / 110,000 |
Martensitic stainless steel with excellent CO₂ corrosion resistance. Ideal for sweet (CO₂) environments and moderate sour service up to elevated temperatures. |
|
28Cr-80/110 |
80,000 / 110,000 |
High-chromium corrosion-resistant alloy for extreme sweet and sour environments. Provides superior resistance to both CO₂ and H₂S corrosion. |
Premium connections (such as VAM®, VAM TOP®, NEW VAM, and TPCO proprietary connections) offer enhanced sealing integrity compared to standard API threads.
Key benefits of premium connections:
Metal-to-metal seal for superior gas tightness
Reverse angle torque shoulder for precise make-up control
100% pipe body compression rating on select designs
ISO 13679 CAL-IV qualification for critical service
Interchangeability between VAM® families
Compatible with martensitic stainless steels (13Cr, Super 13Cr) and nickel-base alloys

Selecting the right tubing involves matching well conditions to steel grade and connection type:
Depth & Pressure – Deeper wells and higher pressures require higher strength grades (P110, V150).
Corrosive Environment – H₂S (sour) requires C90, T95, or L80; CO₂ (sweet) requires 13Cr or 28Cr stainless grades.
Connection Integrity – Standard API threads (EUE, NUE) are economical; premium connections (VAM TOP, NEW VAM) offer superior gas sealing for HP/HT wells.
Well Type – Conventional vertical wells may use NU; deviated or deep wells typically require EU or premium connections.
As a specialized trading company with strong factory partnerships, Sunrise offers:
API 5CT certified material – Full traceability with mill test certificates.
Complete grade coverage – From J55 to high-alloy 28Cr grades.
Flexible length options – R1, R2, or R3 to match your well design.
Premium connection supply – Standard API or VAM® family premium threads available.
Global logistics support – Export documentation, sea/air freight, and delivery to remote locations.
Contact us to order API 5CT oil tubing for your production well, injection well, or workover project. We provide the right grade, connection, and length for your specific well conditions.
