Product Introduction III: Special Connections
Product Overview
Special connections are a key component in oil country tubular goods (OCTG), used to connect casing and tubing. Their performance directly impacts the safety and efficiency of oil and gas extraction. Tianjin Grand Victory Company produces special connections with advanced design concepts and manufacturing processes, ensuring high sealing performance and strength. Our special connections are widely used in both land-based and offshore oil and gas fields, meeting the demands of different well depths and geological conditions.II. Outer Diameter Specifications
Tianjin Grand Victory Company offers a variety of outer diameter specifications for special connections to meet the needs of different customers. Common specifications include:
- 2.375 inches (60.3mm)
- 2.875 inches (73.0mm)
- 3.5 inches (88.9mm)
- 4.0 inches (101.6mm)
- 4.5 inches (114.3mm)
These special connections are manufactured using advanced production processes to ensure precision in outer diameter and connection stability.
Yield Strength
Yield strength is a critical performance indicator for special connections, determining the maximum pressure they can withstand underground. Tianjin Grand Victory Company's special connections offer a wide range of yield strengths to meet the needs of different extraction environments:
- J55 special connection: Minimum yield strength of 35,000 psi (241 MPa)
- N80 special connection: Minimum yield strength of 45,000 psi (310 MPa)
- P110 special connection: Minimum yield strength of 75,000 psi (517 MPa)
- 13CR special connection: Minimum yield strength of 75,000 psi (517 MPa), maximum yield strength of 105,000 psi (724 MPa)
These different strength grades of special connections can adapt to various complex conditions, from shallow to deep wells and from conventional extraction to high-sulfur hydrogen environments.
pellet machine, with the advantages of low noise, easy and stable operation,
