Choosing the Right Pipe Hangers and Supports: Types and Applications Explained

In any piping system—whether in industrial plants, commercial buildings, or residential setups—the structural integrity and longevity of the system depend heavily on pipe hangers and supports. These crucial components help distribute the weight of the pipes, absorb vibrations, accommodate thermal movement, and prevent sagging or damage.

Understanding the different types of pipe supports and their specific applications is essential for proper system design and safe operation. Let’s explore the most common pipe support types, selection factors, and real-world applications.

Common Types of Pipe Hangers and Supports

Pipe supports come in various forms to suit different conditions and piping needs. Each type is designed to handle specific loads, motions, and environmental factors. Below, we break down some of the most widely used types of pipe hangers and supports.

Rigid Pipe Supports

Rigid supports are used when the pipe movement must be limited or completely restricted. These supports do not allow vertical movement and are typically used in systems where pipe alignment is crucial and movement could lead to system failure or damage.

Common rigid supports include:

• Pipe clamps and U-bolts: Secure pipes to beams or walls.
• Adjustable stanchions: Provide vertical support and can be customized for different elevations and pipe sizes.

One popular option in this category is the adjustable pipe support stanchion, which is ideal for vertical adjustments in rigid systems. These supports are often used in refineries, power plants, and water treatment facilities.

Spring Hangers and Supports

Spring hangers are designed to support the pipe while allowing vertical movement due to thermal expansion or contraction. They are most commonly used in systems where high temperatures cause pipes to expand and contract significantly.

There are two main types:

• Variable spring supports: Designed for applications where load variation is acceptable within a range.
• Constant spring supports: Used when it's critical to maintain a constant load even as the pipe moves.

These supports are typically found in high-temperature systems such as steam lines, chemical processing plants, and boiler systems.

Sway Braces and Vibration Dampers

Sway braces and vibration dampers play an essential role in stabilizing piping systems against dynamic forces. These supports prevent excessive movement caused by seismic activity, fluid hammering, or equipment vibrations.

• Sway braces: Control pipe motion in response to lateral forces.
• Snubbers: Absorb shock loads and sudden movements.
• Vibration dampers: Reduce high-frequency vibrations to protect both pipes and connected machinery.

They are commonly used in HVAC systems, power generation facilities, and areas prone to seismic activity or mechanical movement.

Specialty Pipe Supports

In addition to standard support types, there are specialty pipe supports designed for unique or demanding conditions:

• Cryogenic supports: Insulated to prevent thermal bridging and protect from extreme cold.
• Insulated pipe supports: Minimize heat loss or gain and prevent condensation.
• Guides and anchors: Restrict movement in certain directions while allowing it in others.

Specialty supports are essential in chemical plants, food processing industries, and cleanroom environments where cleanliness and temperature control are critical.

Factors to Consider When Selecting Pipe Supports

Choosing the right pipe hangers and supports involves evaluating several key factors:

• Load Requirements: Determine the weight of the pipe and its contents. This includes static loads, dynamic forces, and potential overloads.
• Pipe Movement: Consider thermal expansion, contraction, and vibration. The right support should accommodate this movement without damage.
• Environmental Conditions: Think about temperature, humidity, corrosive atmospheres, and exposure to chemicals.
• Support Location: Is the pipe suspended from a ceiling, anchored to a floor, or attached to a wall? The location impacts the type of support needed.
• Compliance with Codes: Follow industry standards such as ASME, ANSI, and local building codes to ensure safety and compliance.
• Installation and Maintenance: Some supports are easier to install and maintain than others. Consider future access and adjustments.

Applications of Different Pipe Support Types

Different industries and systems require different types of supports based on operational needs. Here’s a breakdown of typical applications for each type:

• Rigid Supports: Found in systems with minimal thermal expansion—such as water pipes in commercial buildings, or process lines in manufacturing facilities.
• Spring Hangers: Common in steam lines and chemical processes where temperature variations are significant.
• Sway Braces and Dampers: Used in dynamic systems, like HVAC ducts in skyscrapers, or piping near rotating equipment like pumps and turbines.
• Specialty Supports: Essential in sensitive environments such as cryogenic storage, food-grade processing lines, and pharmaceutical cleanrooms.

These supports not only maintain pipe alignment and integrity but also extend the lifespan of the entire piping system by minimizing stress and preventing failures.
