In a world where the bones of our infrastructures are crisscrossed with pipes, one of the most overlooked, yet vital, components of these networks are pipe supports. These silent heroes bear the weight, literally, of our various systems, to help ensure smooth, unbroken service. This article will explore the diverse range of pipe support types, and their applications.

A pipe support, sometimes referred to as a hanger, is a structural component designed to carry the weight of a pipe, its contents, insulation, and any other in-line equipment such as valves and fittings. They provide stability and manage the stresses incurred due to the movement or vibration of the pipes. Pipe supports are essential for maintaining the integrity and performance of the pipe systems.
There are various types of pipe supports designed to perform different functions. Some are designed to allow movement (such as expansion and contraction due to temperature changes), while others are meant to provide rigid, immovable support.
Choosing the right type of pipe support is critical as it directly influences the safety, functionality, and lifespan of the piping system.
Factors that influence this choice can include the material of the pipe, the substance being transported, the operating temperature, and environmental conditions.
Fixed point supports, also known as anchors, are a specific type of support used in a piping system that provides a rigid and immovable point of reference. They are designed to bear the weight of the pipe, along with its contents, and to absorb the various forces that the pipe system might experience, such as those due to thermal expansion, contraction, and other dynamic loads.
Guide supports allow axial movement of the pipe (along the length of the pipe), while preventing lateral (sideways) and angular (rotational) movements. In other words, they permit the pipe to expand or contract linearly while keeping it aligned along its originally designed path.
Guide supports are typically installed at regular intervals along straight pipe runs, particularly between changes in direction, and help maintain the alignment and positioning of the pipe.
Line stop supports or limit stop supports are used to prevent pipes from moving in either the axial or longitudinal direction. They keep the pipe in place and can be provided to facilitate favorable distribution or restriction of axial pipe movements.
Hanger rod supports, commonly known as hangers, are a type of pipe support used predominantly in the suspension of pipes from the ceiling or elevated structures. These types of supports are a common sight in industrial settings where large networks of pipes traverse across areas, often overhead.
Hanger rods are typically composed of a metal rod that is secured to a structural ceiling member at one end and a clamp or other attachment point that connects to the pipe at the other end. The length of the hanger rod can be adjusted to accommodate the distance between the pipe and the supporting structure in order to provide flexibility in pipe positioning.
Spring supports are used to reduce the impact of temperature changes and subsidence on pipes by absorbing their upward or downward movement. They can also be used with hanger rods to handle any horizontal movement.
U-bolts have two main purposes in a piping system: anchoring and guiding. Depending on the intended purpose, they provide support to pipes in different ways, but the ultimate goal is to enhance the support of the pipes.
Trunnions are essentially short sections of pipe welded to the elbow section or side of a pipe that allow it to rest on structural steel members. This design helps in distributing the load and pressure of the piping system to effectively reduce the amount of stress on the pipe. It also permits some rotational movement in the pipe system.
Trunnions are often used at changes of direction or bends in the pipe system, particularly where the piping system involves large horizontal runs. Trunnions effectively bear the weight of the pipe and the fluid it carries to minimize potential sagging or deformation due to gravity.
Saddle supports are a specific type of pipe support used primarily for large-diameter, horizontal pipes. Saddle supports are designed to distribute the weight of the pipe and its contents evenly across the structure to help reduce the stress on any one point.
The name &#;saddle&#; comes from their design, which looks like a saddle &#; it has a curved section that fits against the bottom of the pipe, and flat sections that rest on the supporting surface beneath. This design increases the contact area with the pipe, and distributes the weight more effectively to reduce the likelihood of local deformations due to concentrated loads.
In addition to their load-distributing role, saddle supports can also help to minimize movement or vibration in the pipe, to further enhance the stability of the piping system.
Buckaroos is a stalwart in the industry that produces a wide variety of pipe supports, each designed and constructed to the highest standards.
The CoolDry&#; Insulated Saddle by Buckaroos is a highly rated saddle system for commercial piping systems that can handle temperatures up to 250°F. It uses a strong phenolic foam pipe Insulation, with a 3.75 PCF rating for piping under 10&#; iron pipe size and 5 PCF rating for larger pipes between 11&#; and 30&#; iron pipe size.
The CoolDry&#; Sliding Supports have an insulated sliding saddle feature that allows a certain amount of linear movement at the hanger location while still keeping the insulation intact. This support system for pipe insulation can handle temperatures from -290°F to +250°F, and removes the need for roller type supports.
If your piping system undergoes frequent expansion and contraction, the CoolDry&#; Heavy Duty Pipe Supports is a great choice. It works well for refrigerated water and cold piping systems, and can be used with roller hangers, trapeze systems, and strut systems. You can also use it outdoors, as long as it&#;s protected from bad weather. It also meets MSS SP-58, Type 40 shield requirements.
The Tru-Balance&#; Model E is a top-quality pre-insulated saddle system for commercial piping systems with temperatures up to 300º F. It comes with rigid polyisocyanurate insulation, which is 3 PCF for sizes up to 12&#; IPS and 4 PCF for sizes 13&#; and larger. The E also features a vapor retardant facing that doesn&#;t promote mold or fungus growth.

Pipe supports are a critical component to safe and effective piping system engineering.
Much like other pipe components, implementing supports during design and system implementation can help to significantly reduce costs and ease the installation of any required supports.
This guide will provide a foundational overview of pipe support functions, critical pipe support roles, standards and codes, and standard pipe support designs to help you better understand this complex yet critical topic.
The term pipe supports can often refer to two different types of components: supports and restraints.
However, both product types are essential for safe long-term operation and are effectively both classified under the single umbrella of pipe support systems.
Supports typically help to shoulder and distribute loads across the system in a manner that allows for safe operation and helps to tie the piping system into structural elements for increased safety and support for all parts of the piping process.
In most cases, these objects help minimize and carry the impact of vertical loads. Restraints work alongside supports, helping to limit movement and ensure that pipes remain positioned within a tolerance determined in the system engineering specifications.Typically, they help to minimize and carry the impact of horizontal loads.
Pipe supports can make the difference between safe operation and complete systems failure&#;especially in emergencies or moments of non-standard operation.
A well-designed pipe support system will ensure everything remains within tolerance if pipe loads surge, structures shift, or temperatures change drastically.
They can also help to support or trigger overflows and other fail-safes to mitigate the affecting condition and return the system to normal operation as quickly as possible and with minimal risk to both piping systems and operational staff.
As with most piping products, determining the best pipe support products, sizes, and implementations will require knowing your exact needs, operating environments, budget, and myriad other factors.
However, in most cases, pipe supports are expected to perform one or more of the following tasks:
Yes!
The exact standards applicable to your piping system will depend on your industry and location in most cases.
However, the following are some of the principal codes and standards to consider in common locations around the world:
US Codes and Standards: MSS-SP-58, MSS-SP-69, and MSS-SP-89
UK Codes and Standards: BS-
Germany Codes and Standards: VGB-R-510 L
There are numerous ways to consider grouping pipe support products depending on the factors you consider important.What type of insulation you desire, your intended attachment method, your intended attachment location, and the amount of anticipated movement in your system, for example, might all create different groups of products.You must consider all elements of your system and consult with an experienced engineer to ensure that your supports meet your needs.Instead of grouping by use type, we will list the different core designs for pipe supports and pipe restraints available and, where applicable, discuss their pros and cons to help you determine the ideal products for your system based on your needs.
These pipe supports are typically primary supports, meaning they usually connect directly to the pipe to support the piping system load.
Common pipe bearing support design types include:Exact installation requirements will depend on the size and design of the support chosen.
However, in most cases, these supports are either bolt-fastened or welded.
should remain similar to those of the supported pipes to ensure similar behavior's when welded and comparable performance when exposed to piping process elements or environmental variables.These pipe supports can work as either primary or secondary supports, providing variable resistance to movement based on compression and other variables.
Common design types include:
Often, these supports are used to minimize the impact of abnormal dynamic conditions, including but not limited to seismic activity, pump trips, safety/relief valve discharge, or rapid valve closure.Because the resistance varies, this can allow for one set of standard movements during normal operation while maintaining strict movement tolerances during abnormal conditions.
Constant spring supports typically feature designs and options similar to dynamically loaded supports.
However, the supports are configured to maintain a static resistance level instead of adjusting resistance based on load and other variables.
This makes them ideal for use in extremely high load conditions or systems where movements and loading conditions can create substantial load variability.
Constantly loaded supports (or constants) typically come in horizontal or vertical designs to help match the support to the load type.
However, unlike previous types mentioned, these are limited more or less to the same overall components and design.
