Pipe supports are crucial for safe and efficient pipe engineering. Incorporating a support system in the design of piping systems helps control costs and facilitates the installation of necessary pipe supports. In this article, we will explain the foundations of effective pipe support systems, the essential roles of pipe supports, and standard pipe support designs to enhance your understanding of this important subject. Pipe supports are often categorized into two different component types: supports and restraints. Both are essential for long-term operation and are collectively classified as part of pipe support systems.

Supports are designed for use in both high and low-temperature environments, with their primary function being to handle load-bearing requirements. Pipe supports are used for various material types in commercial and industrial applications.

• Brass: Brass pipes, known for their long lifespan, are best chosen with at least 85% copper for durability.

• Cast Iron: Due to its weight, cast iron is typically used in sewer lines and commercial water distribution systems. It is fire-resistant, soundproof, and capable of handling heavy pressure.

• Copper: Copper’s durability and corrosion resistance make it ideal for both cold and hot water, as well as for plumbing and refrigerants, due to its ability to handle high pressures.

• CPVC: CPVC piping is unsuitable for freezing conditions as it splits, and it cannot be recycled once removed. However, it is safe for drinking water due to added chlorine and is easy to work with, making it popular for DIY plumbing.

• PFX: PFX is a versatile plastic plumbing pipe that tolerates heat and cold, suitable for water supply systems. It is easy to bend or twist around obstacles indoors or outdoors.

• PVC: PVC piping is inexpensive but has drawbacks. It splits in freezing temperatures, causing leaks, and does not handle UV rays or heat well. Its uses are limited to drainage and indoor applications.

• Stainless Steel: Stainless steel pipes are strong and fire-resistant but expensive, limiting their commercial use. They are also susceptible to corrosion.

Knowing the material and job setting is part of the problem. Sizing and cradles are also needed. Integrating components such as valves, meters, and fittings into the piping system necessitates careful computation to ensure they do not exceed the pipes’ integrity. Failure to meet these requirements requires further calculations. While it does seem overzealous to do so much with fitting pipe supports, the results are well worth it. Typically, pipe supports are anticipated to fulfill one or more of the following functions:

• Prevent, reduce, or eliminate pipe stresses to maintain permissible thresholds.

• Prevent, reduce, or eliminate leakage at joints caused by movement, shifting, or load stress.

• Absorb or minimize line vibrations during operation.

• Mitigate or minimize the effects of dynamic loadings, including seismic shifts, wind stress, and water hammering.

• Prevent excessive pipe sag according to relevant implementation and standards.

• Facilitate the management of temperature extremes (both environmental and process-related) to ensure safe and consistent operation of the piping system.

• Help safeguard integrated equipment, such as sensors, gauges, valves, and gates, from failure caused by excessive loading.

• To effectively manage and direct thermal loads according to specified thresholds and operational processes.

• To assist in supporting and minimizing load stresses on other components within the piping support system.

In conclusion, the installation of piping in hangers or other supports to achieve insulation efficiency requires careful consideration of the types, sizes, weights, and lengths of the equipment involved. When evaluating hanger/support systems, please consider Carpenter & Paterson.
