Oil Country Tubular Goods (OCTG) Product Description
1. Product Overview
Oil Country Tubular Goods (OCTG) are core steel pipe products specially designed for oil and gas exploration, development, production and long-distance transportation. They are widely used in oil well drilling, well completion, oil and gas extraction and pipeline transmission projects, adapting to complex working conditions such as deep wells, high pressure, high temperature and corrosive environments.
Our OCTG products are strictly manufactured in accordance with API (American Petroleum Institute) international standards, national mandatory standards and industry specifications, with stable performance, high precision and strong durability, fully meeting the technical requirements of global oilfield engineering projects.
2. Product Categories & Main Applications
2.1 Oil Casing
Used for well wall cementing to maintain the stability of wellbore structure, isolate oil, gas and water layers, and prevent wellbore collapse. It is the key component to ensure the safe operation of oil and gas wells throughout the life cycle.
2.2 Oil Tubing
Served as the transmission channel for oil and gas flowing from the bottom of the well to the wellhead, featuring good sealing performance and corrosion resistance to ensure efficient and safe oil and gas extraction.
2.3 Drill Pipe
Applied in oil well drilling operations to transmit drilling pressure and torque, convey drilling fluid, and cooperate with drilling bits to complete rock breaking and well drilling, suitable for various conventional and special drilling projects.
2.4 Line Pipe
Used for ground and long-distance transportation of crude oil, natural gas and petroleum products, with excellent pressure resistance and weldability to meet the needs of cross-regional oil and gas pipeline networks.
3. Main Technical Standards
• API 5CT: Specification for Casing and Tubing
• API 5DP: Specification for Drill Pipe
• API 5L: Specification for Line Pipe
• GB/T 19830, GB/T 9711 and other international advanced standards
4. Key Technical Parameters
4.1 Size Range
• Outer Diameter (OD): 2-3/8 inches to 20 inches
• Wall Thickness: Standard thickness (STD), extra strong (XS), double extra strong (XXS) and customized special wall thicknesses
• Length: R1 (random length), R2 (single length), R3 (double length)
4.2 Steel Grades

• Line Pipe: X42, X46, X52, X56, X60, X65, X70, X80, X100
4.3 Connection Types
• Conventional Threads: BTC (Buttress Thread Coupling), LTC (Long Thread Coupling), STC (Short Thread Coupling), EUE (Extended Upset End)
• Premium Connections: Sealed premium threaded connections (customized according to customer requirements)
5. Product Performance & Advantages
1. High Strength & Toughness: Adopt high-quality steel billets and advanced heat treatment processes, with excellent collapse resistance, tensile strength and impact toughness, adapting to harsh deep well environments.
2. Superior Corrosion Resistance: Provide carbon steel and corrosion-resistant alloy products, effectively resisting H₂S, CO₂, salt water and other corrosive media, extending service life.
3. Precise Dimensional Tolerance: Strictly control outer diameter, wall thickness and thread accuracy, ensuring good interchangeability and reliable connection sealing.
4. Stable Quality: Full-process quality inspection from raw material procurement to finished product delivery, with complete quality certificates and third-party testing reports.
5. Customized Service: Support customized production of specifications, steel grades and connections according to customer project needs.
6. Packaging, Transportation & Certification
6.1 Packaging
Standard export packaging: Steel pipe ends equipped with plastic/steel protectors, bundled with steel strips, equipped with moisture-proof and anti-collision protection; fumigated wooden pallets or steel frames are available for customized packaging to meet international transportation standards.
6.2 Transportation
Suitable for container transportation and bulk cargo transportation, with fixed protection measures to ensure product safety during long-distance transportation.
6.3 Certification
Products have API monogram certification, ISO quality management system certification, and can provide material test certificates (MTC), third-party inspection reports (SGS, BV, CCIC) and other complete documents.
7. Application Scope
Suitable for onshore and offshore oil and gas exploration and development projects, oil and gas long-distance pipeline construction, oilfield well workover and reconstruction, and other petroleum engineering fields, widely sold to major oilfield regions around the world.
