 Product Introduction V: Connectors

 I. Product Overview

Connectors 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 Longkai Lai Company produces connectors with advanced design concepts and manufacturing processes, ensuring high sealing performance and strength. Our connectors 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 Longkai Lai Company offers a variety of outer diameter specifications for connectors 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 connectors are manufactured using advanced production processes to ensure precision in outer diameter and connection stability. Additionally, we can provide customized specifications according to specific customer needs.

 III. Yield Strength

Yield strength is a critical performance indicator for connectors, determining the maximum pressure they can withstand underground. Tianjin Longkai Lai Company's connectors offer a wide range of yield strengths to meet the needs of different extraction environments:

- J55 connector: Minimum yield strength of 35,000 psi (241 MPa)

- N80 connector: Minimum yield strength of 45,000 psi (310 MPa)

- P110 connector: Minimum yield strength of 75,000 psi (517 MPa)

- 13CR connector: Minimum yield strength of 75,000 psi (517 MPa), maximum yield strength of 105,000 psi (724 MPa)

These different strength grades of connectors can adapt to various complex conditions, from shallow to deep wells and from conventional extraction to high-sulfur hydrogen environments.
