Understanding Hangers in Oil & Gas: Supporting the Flow

In the intricate world of oil and gas infrastructure, every component plays a crucial role in ensuring the smooth and safe transportation of these valuable resources. Among the seemingly mundane yet vital elements are hangers, specifically designed to support horizontal pipes.

Hangers are essential pipe supports that suspend a pipe from a stationary object above, effectively preventing sagging and ensuring the integrity of the pipeline. They are crucial for maintaining the flow of oil and gas, preventing potential leaks and ensuring the longevity of the pipeline.

Types of Hangers in Oil & Gas:

There are several types of hangers used in the oil and gas industry, each tailored to specific applications and environments. Some of the most common include:

• Constant Support Hangers: These hangers provide a constant support force, regardless of the temperature changes within the pipe.
• Spring Hangers: As the name suggests, these hangers utilize springs to adjust the support force based on the pipe's thermal expansion and contraction.
• Variable Support Hangers: These hangers offer flexibility in adjusting the support force to accommodate varying loads and pipe movements.
• Truss Hangers: These are commonly used in large-diameter pipelines and consist of a triangular framework that provides a robust and stable support structure.

Functions and Benefits of Hangers:

• Load Distribution: Hangers distribute the weight of the pipe evenly, preventing stress points and potential failure.
• Thermal Expansion and Contraction Management: They accommodate changes in pipe length due to temperature fluctuations, mitigating potential strain and leaks.
• Structural Integrity: By supporting the pipeline, hangers contribute to the overall structural integrity of the system, preventing sagging and ensuring stability.
• Safety: Properly installed hangers significantly enhance the safety of the pipeline by reducing the risk of failures and leaks.

Factors to Consider When Choosing Hangers:

• Pipe Diameter: The size of the pipe influences the type and strength of hanger required.
• Fluid Type and Pressure: The characteristics of the transported fluid, including pressure and temperature, impact the design and materials used for the hanger.
• Environmental Conditions: Factors like temperature, humidity, and corrosion risk necessitate specific hanger materials and coatings.
• Installation Requirements: Accessibility and the specific conditions of the installation site influence the choice of hanger type and installation procedures.

Conclusion:

Hangers are often overlooked yet play a critical role in the seamless operation of oil and gas pipelines. Understanding their various types, functions, and considerations is essential for ensuring the safe and efficient transportation of these valuable resources. Choosing the right hangers for specific applications contributes to the long-term reliability, safety, and economic viability of the entire oil and gas infrastructure.
