Spring Hangers are designed to isolate low-frequency vibrations in suspended piping and equipment, preventing vibration transmission to the building structure through the piping systems. The products incorporate a color-coded steel spring for easy identification in the field. Easyflex offers pre-compressed, 30° angularity, and pre-positioning hangers.
Zhiang supply professional and honest service.
Our pre-compressed designs are pre-compressed to the rated deflection to support the suspended equipment or piping at a fixed elevation during installation, regardless of load changes. The angularity hangers have a 30° misalignment capability, spring diameters, and hanger box lower hole sizes are sufficiently sized to permit the hanger rod to swing approximately 30° before contacting the box.
Pre-positioning hanger designs incorporate a means for supporting the suspended equipment or piping at a fixed elevation during installation, regardless of load changes and transferring the load to the spring.
Spring hangers and spring mounts are one of the most sought-after anti-vibration products to restrict vibrations in suspended structures, pipes, ducts, rotary machinery, and vertical systems that support a heavy load.
But before you choose the right spring hanger for your business application, you must know some of the common terminologies that determine the characteristics of spring.
Tension:
When the spring in rest or neutral position is stretched through the application of external force, the spring is in tension. The tensile stress of a spring is determined by the tensile strength applied per unit area of the spring. A spring hanger that is subjected to heavy load should ideally be resistant to high tensile stress.
Compression:
When a spring is compressed from its free form through external force, it is said to be in compression. The compressive stress of the spring is calculated by the compressive force applied per unit area of spring (lbs/in²). One must calculate the compressive stress of a spring hanger or spring mount to determine if it is apt for their specific application.
Shear:
When spring is subjected to equal and opposite forces but not on the same axis, these forces can shear the spring into two. Shear stress is calculated by the shear force applied to the unit area of the spring (lbs/in²). When spring is in a state of stress, it experiences tension, compression, and shear simultaneously.
Spring Constant:
The tension or compression of the helical spring is directly proportional to the force applied to the spring. The ratio of proportionality of the force used with the displacement of the spring is known as the spring constant. Units lbs/in.
F=Kx
Where,
F= External force on spring.
x= Displacement of spring (Compression or tension)
K= Spring Constant.
In a helical spring, the spring constant remains the same until the force is within the elastic limit of the spring.
Force Deflection of Spring:
This is defined by the shape of the force-displacement curve, which is generally a straight line as the spring constant remains unchanged within the elastic limit of spring. If the constant spring increases with displacement, it is referred to as a hard spring, and when the spring constant decreases with deflection, it is called a soft spring.
Energy Storage:
The area under the force-displacement curve is a measure of energy stored in the spring during tension, compression, or shear.
Preload:
If a spring is not at its natural length during rest or neutral position, it is said to be in compression or tension. The amount of tension or compression in the rest position is called the preload of a spring.
Elastic Modulus and Shear Modulus:
If the force applied to the spring is greater than its elastic limit, it can cause permanent deformation. The ratio of force exerted on the spring to the amount of deformation of the spring is called elastic modulus. On the other hand, the shear modulus is the shear stress and strain ratio.

Utilizing the right pipe hanger is essential for ensuring the stability and integrity of piping systems. Pipe hangers provide support and help prevent damage, and several important elements need to be considered when selecting the most suitable option. The factors that impact pipe system performance include the environment in which it is installed and the particular requirements of the system.
This article will outline the key considerations to keep in mind when choosing a pipe hanger for your project.
Pipe hangers are hardware used in construction and plumbing to steady and support pipes. They help align, reduce vibration, and prevent sagging by suspending pipes from walls or ceilings. Pipe hangers are versatile and can support different pipe materials, including PVC, copper, and steel. They come in different designs and sizes to fit various pipe sizes, applications, and load capacities.
A Clevis hanger is used to support horizontal pipe runs in a variety of different applications. It’s designed to enable the efficient suspension of piping in heating, ventilation, and air conditioning (HVAC) systems, among other utilities.
The Clevis hanger is comprised of a clevis and a U-bolt. The clevis wraps around the pipe, while the U-bolt fits over it. The two parts are secured with nuts for hanging the pipe at an adjustable height and angle, which is one of the benefits of using a clevis hanger.

Featured content:Riser clamps are specifically designed to support vertical piping. They clamp onto the pipe and allow the pipe’s weight to be carried across a larger area. They are often used in building and industrial applications where vertical pipes need to be secured and supported, especially when running through multiple floor and ceiling levels.
A riser clamp works by transferring the load of the pipe to the building structure. It encircles the pipe and is tightened to hold the pipe securely. The lower part of the clamp, which is flat, rests on the upper surface of the structural member (like a floor or a beam). The upper part of the clamp grips the pipe to prevent it from moving downward.
A Sliding saddle is a type of pipe support designed to manage both the weight of the pipe, and any movement from thermal expansion and contraction. It consists of two main parts: the saddle and a base that it can slide on. The saddle is shaped to fit the contour of the pipe, and distribute its weight over a larger area to reduce the pressure on any single point.
The sliding base underneath the saddle is typically constructed of two plates of material, often metal, with low friction between them. One plate is fixed, and the other is connected to the saddle, and can slide on the fixed plate.
J-Hangers are ideal for light loads and can be easily attached to structural members with a rod or fastener. The J-shaped design provides superior support for piping systems. J-hangers are often used for light-duty applications, particularly with smaller diameter pipes such as those used in residential or light commercial plumbing.
One end of the J-hanger is typically attached to a structure such as a wall or ceiling using screws or other fasteners, while the curved portion of the J provides support for the pipe. The design allows the pipe to be easily inserted and removed from the hanger, which makes it a flexible choice for installations where adjustments may be needed.
Band hangers are brackets that support insulated or non-insulated pipes from overhead and allow for vertical adjustment. They are frequently utilized in fire safety sprinkler systems to suspend and join piping. Band hangers are used in commercial buildings and large multi-family complexes due to their lightweight design and lower costs.
Spring hangers are used for supporting piping systems that undergo significant vertical movement due to thermal expansion contraction, vibrations, or other dynamic forces.
Spring hangers consist of a spring mechanism that allows the pipe to move while still providing support. The spring mechanism can either be variable spring hangers or constant spring hangers, depending on the application:
Variable spring hangers work on the principle that the support load remains relatively constant while the pipe moves. As the pipe moves due to thermal expansion or contraction, the spring compresses or expands to accommodate the movement to maintain the support.
Constant spring hangers maintain a nearly constant supporting force over the entire travel range of the support. This is usually accomplished by a mechanical system within the support that compensates for the changing spring force as the hanger moves.
Constant spring hangers are typically used in situations where a variation in the force supporting the pipe could cause problems, such as damage to the pipe or connected equipment.
Split ring hangers are a type of pipe hanger used to suspend or mount pipes, especially in scenarios where the pipe cannot be turned or moved significantly.
They are commonly used in both light industrial and commercial applications. As their name suggests, split ring hangers are designed as a ring that is split into two parts.
This allows them to be installed or removed without having to lift or move the pipe, which makes them a convenient choice for certain installations. The hanger encircles the pipe to provide support over a large surface area, which can help to distribute the weight of the pipe and reduce stress points.
Typically, one end of the hanger is bolted or screwed into a wall, ceiling, or other structural member, while the other end can be adjusted to securely grip the pipe.
Roller hangers and supports are a specialized type of pipe support used to accommodate the movement of the pipes due to thermal expansion, contraction, and other dynamics. They consist of a hanger attached to a structure like a ceiling or wall, and a roller that the pipe rests on.
The roller allows the pipe to move back and forth with less friction than if it was resting directly on a stationary hanger. This can help reduce stress on the pipe, particularly in high-temperature applications where thermal expansion and contraction can be significant.
Selecting the right type of pipe hanger involves considering the specific needs of your piping system, including load, movement, and temperature conditions. Buckaroos, Inc. offers a comprehensive range of high-quality pipe hangers to meet diverse system requirements, for effective, long-lasting pipe support.
Here are some key considerations:
Some materials may require specific types of support or may not be compatible with certain types of hangers. For example, copper piping may need specific types of hangers to prevent galvanic corrosion when in contact with different metals.
The diameter and weight of the pipe, including the weight of the contents it carries, are key factors. Larger, heavier pipes require stronger, more robust hangers.
If the pipe carries fluids at high temperatures, it may expand and contract significantly. In such cases, adjustable or flexible hangers like spring hangers or roller hangers, which can accommodate this movement, might be needed.
In some applications, such as machinery or equipment that generates vibrations, specialized hangers designed to dampen or resist vibration may be necessary.
In environments where corrosion is a concern, such as in chemical plants or outdoor installations, hangers made from corrosion-resistant materials or with protective coatings may be necessary.
Ensuring that the weight of the pipe is evenly distributed can help prevent damage to the pipe. Certain hanger designs, like band hangers, are particularly good at evenly distributing the load.
Buckaroos® Sliding Saddles are special saddles designed for use in dynamic piping systems. They provide controlled linear movement at hanger locations. Sliding Saddles can be used instead of roller hangers, which can be expensive and prone to rust. A combination of Sliding Saddles, Clevis hangers, and rigid insulation is cost-effective and more efficient. You can easily identify each Sliding Saddle by its Sliding Saddle sticker label.
The CleviShield™ from Buckaroos offers protection to the vapor barrier that encapsulates the pipe and a durable means of supporting overhead piping, ranging in size from 2” O.D. to 12” O.D. The product is composed of a galvanized shield that rests in a centered position inside a galvanized clevis hanger. The two components are welded together at point of contact. Depending on the application, the CleviShield™ is available in galvanized carbon steel or stainless steel.
The High Density Fiberglass Blocks come in different sizes and are used to provide support for insulated pipes that pass through load-bearing clevis hanger support locations. They help maintain uniform insulation thickness and prevent any damage that could occur from compression.
The Buckaroos® Support is a wooden dowel precision-cut and attached to a PVC disc. The supports are designed to provide extra strength to pipe insulation where it passes through load-bearing clevis hanger supports on insulated pipe systems. By adding rigidity, the insulation is better protected from being compressed excessively or getting damaged, which helps maintain its consistency and thickness.
Buckaroos Clean Saddles™ are used to support medium and light compressive strength pipe insulations in Clevis hanger piping systems. The saddles work with various pipe insulation materials such as rubber tubing, phenolic foam, polyisocyanurate, cellular glass, and fiberglass. They are particularly useful for ammonia refrigeration, chilled water, refrigeration, plumbing, and heating piping systems.
