Proper pipeline integrity depends significantly on selecting the right type of pipe support. Indeed, ASME B31.3, the code for process piping, provides guidelines for designing pipe supports that ensure both safety and operational efficiency. These supports mitigate stress from various forces. They act as critical elements within industries ranging from chemical processing plants, where corrosion considerations are paramount, to oil and gas refineries, where high pressures demand robust designs. Each type of pipe support – from spring hangers to rigid struts – presents unique advantages and disadvantages tailored to specific operational and environmental demands.

Crafting the Ultimate Guide to Pipe Support Types
Creating a comprehensive guide to pipe support types requires a structured approach. The key is to ensure clarity, accessibility, and a logical flow of information to address the central theme: type of pipe support. Here’s a suggested layout to achieve that:
Introduction: Why Understanding Pipe Support Types Matters
This section serves as a foundational element. It needs to immediately grab the reader’s attention and establish the importance of understanding different types of pipe supports.
- Hook: Start with a compelling statistic or real-world scenario highlighting the consequences of inadequate or incorrect pipe support. For example, mention potential failures, safety hazards, or financial losses.
- Purpose Statement: Clearly state the article’s objective: to provide a comprehensive overview of various pipe support types and their applications.
- Brief Definition: Define what pipe supports are in layman’s terms, emphasizing their role in maintaining the integrity and functionality of piping systems.
- Outline: Briefly mention the key areas that will be covered in the article, essentially providing a roadmap for the reader.
Categorizing Pipe Supports
This section establishes the high-level categories under which different type of pipe support falls.
Broad Classifications
Divide pipe supports into broad categories based on function and/or material, allowing for initial understanding.
- Rigid Supports: Provide a static connection, restricting movement.
- Flexible Supports: Accommodate thermal expansion and contraction.
- Hanger Supports: Suspend the pipe from overhead structures.
- Base Supports: Provide support from below, typically on the floor or a concrete pad.
Support Material
Explain common materials used for pipe supports.
- Steel: Common and robust, suitable for many applications.
- Stainless Steel: Corrosion-resistant, ideal for harsh environments.
- Alloy Steel: Offers higher strength and temperature resistance.
- Plastic: Lightweight and corrosion-resistant, used for specific applications (e.g., PVC piping).
Detailed Examination of Pipe Support Types
This is the core of the guide, dedicating specific subsections to individual type of pipe support. Each subsection should follow a similar structure for consistency.
Shoe Supports
- Definition: Describe shoe supports, explaining that the pipe rests on a u-shaped "shoe" that sits on a support structure.
- Applications: Indicate where shoe supports are commonly used (e.g., elevated piping systems, providing stability).
- Advantages: Highlight their benefits (e.g., load distribution, easy inspection).
- Disadvantages: Mention their drawbacks (e.g., potential for corrosion between pipe and shoe).
- Visual Aid: Include a clear image or diagram of a shoe support.
Roller Supports
- Definition: Explain how roller supports allow for axial movement of the pipe due to thermal expansion.
- Applications: Describe situations where roller supports are necessary (e.g., long pipe runs subject to significant temperature changes).
- Advantages: Highlight the reduced friction and stress on the pipe.
- Disadvantages: Mention their cost and complexity compared to other types of supports.
- Visual Aid: Include a clear image or diagram of a roller support.
Spring Hangers
- Definition: Describe spring hangers, which use a spring mechanism to accommodate vertical movement of the pipe.
- Applications: Indicate where spring hangers are used (e.g., piping connected to vibrating equipment, locations with variable loads).
- Advantages: Highlight their ability to maintain constant support force even with movement.
- Disadvantages: Mention their maintenance requirements and potential for spring failure.
- Visual Aid: Include a clear image or diagram of a spring hanger.
Rigid Hangers
- Definition: Explain that rigid hangers provide fixed support, preventing any vertical movement.
- Applications: Describe situations where rigid hangers are suitable (e.g., where vibration and movement are minimal).
- Advantages: Highlight their simplicity and low cost.
- Disadvantages: Mention their inability to accommodate thermal expansion and potential for stress concentration.
- Visual Aid: Include a clear image or diagram of a rigid hanger.
Sway Braces
- Definition: Describe sway braces, used to prevent excessive lateral movement of pipes due to wind or seismic forces.
- Applications: Indicate where sway braces are required (e.g., in areas prone to earthquakes or high winds).
- Advantages: Highlight their ability to improve the stability of piping systems.
- Disadvantages: Mention their added cost and complexity.
- Visual Aid: Include a clear image or diagram of a sway brace.
Pipe Clamps
- Definition: Explain the role of pipe clamps in securing pipes to supports.
- Types of Pipe Clamps: Discuss the various designs (U-bolts, clevis hangers, etc.).
- Material Selection: Detail how clamp material needs to be selected based on the pipe’s material and application requirements.
- Visual Aid: Include examples of different types of pipe clamps.
Repeat the structure above for other significant type of pipe support, such as:
- Strut Supports
- Vibration Dampers
- Anchor Supports
- Riser Clamps

FAQs: Pipe Support Types
Here are some frequently asked questions about pipe supports, helping you understand the various types and their applications.
What are the main factors to consider when selecting a type of pipe support?
Several factors influence pipe support selection. These include the pipe’s operating temperature, the weight of the pipe and its contents, thermal expansion and contraction, vibration, and the environmental conditions. Choosing the right type of pipe support ensures stability and prevents damage.
What is the difference between a rigid and a flexible pipe support?
Rigid pipe supports restrict movement in all directions, providing a fixed anchor point. Flexible pipe supports, on the other hand, allow for some degree of movement, typically to accommodate thermal expansion or vibration. The specific type of pipe support chosen depends on the system’s needs.
What are some common materials used to manufacture different types of pipe supports?
Pipe supports are commonly made from carbon steel, stainless steel, or other alloys. The choice of material depends on factors like corrosion resistance, strength requirements, and operating temperature. Different types of pipe support require specific material consideration.
How does improper pipe support selection affect a piping system?
Incorrect selection or installation of the type of pipe support can lead to several problems. These include stress concentrations, excessive vibration, pipe sagging, and even failure of the piping system. Properly designed and installed supports are crucial for long-term reliability.
So, there you have it! Hopefully, you now have a solid understanding of the different types of pipe support and which ones might be the best fit for your project. Choosing the correct type of pipe support can really make a difference. Good luck out there!
