API Tubing Pipe and Casing Pipe for Oil Field
Main Quality: API tubing and casing pipes are manufactured following strict API specifications to ensure reliability and safety in oil field applications. These pipes are essential for the extraction of oil and gas, ensuring secure and efficient operations within the well. The tubes and casings are produced with advanced heat-treatment processes and are equipped with sophisticated testing equipment that guarantees quality and performance.
Description:
- Tubing Pipe: Tubing pipes are used to transport oil and gas from the reservoir to the surface. Their diameters range from 2 3/8″ to 4 1/2″ (φ60~φ114mm), suitable for various oil field applications depending on the specific requirements for well size and pressure.
- Casing Pipe: Casing pipes protect the wellbore from external pressures and conditions while stabilizing the structure. They come in larger diameters, ranging from 5 1/2″ to 13 3/8″ (φ114~φ340mm), to support the drilling process and maintain the integrity of the wellbore.
The API Tubing Pipe and Casing Pipe are produced with high precision and can handle significant pressure and stress encountered in oil extraction. These pipes are subjected to advanced heat treatment to improve strength and durability under harsh operational conditions.

API Tubing and Casing Pipe for Oil Field
Material Grades:
Our API tubing and casing pipes are available in various steel grades to accommodate the diverse needs of oil field operations. The material grades determine the pipe’s strength, hardness, and ability to resist corrosion and high temperatures. Common grades include:
- H40: A standard-grade steel used for lower-pressure operations.
- J55: Frequently used in moderate-depth wells with moderate pressure.
- K55: Similar to J55 but with slightly higher tensile strength, suitable for similar conditions.
- N80: Used in higher-pressure wells due to its increased strength and temperature resistance.
- L80: Resistant to corrosion, especially in environments with high concentrations of hydrogen sulfide (H₂S).
- P110: A high-strength steel used in deep wells and wells with high pressure.
Connection Types:
The type of connection used on tubing and casing pipes plays a crucial role in ensuring the integrity of the well and preventing leaks. Our company offers various connection types that meet API standards, ensuring a secure and tight seal between pipe sections:
- API Threads: Standard long round or buttress threads designed for secure and durable connections.
- Premium Connections: Designed for more challenging drilling environments, premium connections provide enhanced seal integrity and resistance to fatigue, making them suitable for deeper wells and more demanding applications.
Key Features:
- Corrosion Resistance: Our pipes are designed to withstand corrosive environments commonly found in oil and gas fields, especially when exposed to hydrogen sulfide (H₂S) and other chemicals.
- High Tensile Strength: The pipes are manufactured to handle high tensile loads, ensuring they can withstand the weight and pressure of the drilling process.
- Seamless and Welded Options: Depending on the application, both seamless and welded casing and tubing are available to offer the right balance of strength, flexibility, and cost-effectiveness.
- High Pressure and Temperature Tolerance: Our casing and tubing pipes are engineered to operate in high-pressure and high-temperature conditions, essential for deep wells and challenging environments.
More Details:
- Customization: Tubing and casing can be tailored to specific project requirements, including wall thickness, length, and connection type, ensuring a perfect fit for each drilling operation.
- Advanced Inspection Techniques: Each pipe undergoes non-destructive testing (NDT) such as ultrasonic testing, magnetic particle inspection, and hydrostatic testing to ensure they meet the highest quality standards.
- Manufacturing Precision: Our production processes use state-of-the-art technology to maintain tight tolerances on diameter, wall thickness, and thread accuracy, ensuring consistent performance in the field.
Applications:
- Conventional Oil and Gas Wells: These API-compliant pipes are suitable for all types of conventional oil and gas wells, providing long-lasting performance in various geological conditions.
- Unconventional and Deep Wells: For high-pressure, high-temperature environments such as deep and offshore wells, these pipes offer the necessary strength and durability to operate safely and efficiently.
- Hydrogen Sulfide (H₂S) Environments: Our pipes are specially treated to resist corrosion and cracking caused by sour gas exposure, ensuring safe and extended use in such environments.
Conclusion:
Our API Tubing and Casing Pipes provide unmatched reliability and performance in oil and gas drilling operations. Manufactured to strict API standards and equipped with advanced heat-treatment and testing processes, these pipes ensure the integrity of the well, even in the most challenging conditions. Whether you are drilling conventional or high-pressure wells, our range of tubing and casing products offers the strength, durability, and corrosion resistance required for safe and efficient oil extraction.
