API 5CT N80 pipe is an important steel product used extensively in the oil and gas industry for casing and tubing applications. Manufactured according to the API 5CT specification, N80 grade pipes provide reliable mechanical strength, high pressure resistance, and durability in demanding drilling environments.
With the rapid development of global energy exploration, API 5CT N80 pipes are widely used in oil wells and natural gas extraction projects due to their stable performance and cost efficiency.
GengFei Steel supplies high-quality API 5CT N80 pipes to customers worldwide, supporting energy projects with dependable materials and professional export services.
What Is API 5CT N80 Pipe?
API 5CT N80 pipe is a steel pipe designed specifically for use in oil and gas wells as casing or tubing. It is produced according to the American Petroleum Institute (API) 5CT standard, which defines strict requirements for chemical composition, mechanical properties, and manufacturing processes.
The N80 grade belongs to medium-strength casing materials and is widely used in oil wells with moderate depth and pressure conditions.
API 5CT N80 pipes are commonly manufactured in both seamless and welded forms, and they can be supplied with different end connections to meet drilling and completion requirements.
Chemical Composition of API 5CT N80 Pipe
| Element | Typical Content (%) |
|---|---|
| Carbon (C) | ≤ 0.43 |
| Manganese (Mn) | 1.45 – 1.90 |
| Silicon (Si) | ≤ 0.45 |
| Phosphorus (P) | ≤ 0.030 |
| Sulfur (S) | ≤ 0.030 |
These chemical properties help provide the strength and toughness required for oilfield operations.
Mechanical Properties
| Property | Requirement |
|---|---|
| Yield Strength | 552 – 758 MPa |
| Tensile Strength | ≥ 689 MPa |
| Elongation | ≥ 12% |
| Hardness | Controlled to API requirements |
The mechanical characteristics of N80 grade pipes ensure stable performance in drilling operations under high pressure and harsh environments.
Typical Specifications
| Parameter | Range |
|---|---|
| Outer Diameter | 60.3 mm – 508 mm |
| Wall Thickness | 5 mm – 30 mm |
| Length | R1 / R2 / R3 |
| Manufacturing Method | Seamless or Welded |
| End Type | Plain End / Threaded / Coupled |
All products can be supplied with Mill Test Certificates (MTC) and third-party inspection upon request.
