High-Pressure Integral Joint — T-Joint, Y-Joint, L90 Elbow & Cross-Joint for Oilfield Flow Lines
High-Pressure Integral Joints — T-Joint, Y-Joint & L90 Elbow
Product Description
Integral joints are essential components in high-pressure fluid pipeline connections. They effectively achieve fluid diversion, flow merging, and fluid direction changes. Our integral joints are a comprehensive series of products developed through the digestion and innovative improvement of advanced foreign technologies.
Available in sizes from 2" to 3", with a rated working pressure from 42 to 105 MPa (6,000 psi to 15,000 psi). We provide various types of integral joints suitable for room temperature, low-temperature, and sulfur-containing gas conditions.
Our integral joint product line is complete and quality-stable. In addition to standard types, we can customize special-purpose and special-size integral joints according to your specific field requirements.
Design Features
- Integrally Forged Construction: Blanks are integrally forged from high-quality alloy steel and subjected to rigorous heat treatment for high strength and durability.
- Thickened Erosion Zones: In elbows, tees, and other parts where fluid direction changes and internal wall erosion are more severe, a thickened design is adopted to extend the safety service life.
- Uniform Wall Thickness: Compact structure and precision machining ensure consistent performance and fluid dynamics.
- Interchangeable Connections: Standard FIG602 / FIG1002 / FIG1502 connections for quick, easy, and reliable installation.
- Temperature Rating: -29°C ~ 121°C (PU Grade), suitable for demanding environments.
Available Joint Types
- L90 Elbow: 90° direction change for high-pressure flow lines.
- Long Radius 90° Elbow: Smooth pathway to minimize fluid resistance.
- T-Joint: Flow diversion or merging in three directions.
- Y-Joint: Y-shaped flow diversion or merging.
- Manifold Joint: For manifold connection applications.
- Cross-Joint: Four-way flow diversion or merging.
