Pump Piping Support Criteria: Design Guidelines and Best Practices

Pump piping support criteria are the guidelines and standards used to design and install support systems for piping connected to pumps. Proper support is crucial for ensuring the safety, reliability, and efficiency of the pumping system. This article delves into the key criteria typically considered, providing a comprehensive overview of best practices in pump piping support design.

Load Considerations

When designing a support system for pump piping, it is essential to consider the loads that the system will be subjected to. These loads include:

The weight of the pipe, both when full and empty The weight of the fluid being transported Dynamic loads from pump operation, such as vibrations and pulsations

Accurately accounting for these loads ensures that the support system is robust enough to prevent any structural issues that could affect the integrity of the piping.

Support Types

There are multiple types of supports that can be used in pump piping systems, each serving specific purposes:

Hangers are used to suspend piping from overhead structures, helping to balance the load and prevent sagging. Fixed supports hold the piping in place, providing stability and preventing movement. Braces offer additional stability against lateral movements, enhancing the overall rigidity of the system.

Choosing the right combination of supports depends on the specific requirements of the pumping system.

Spacing Guidelines

Proper spacing between supports is critical for the efficient operation of the piping system. The distance between supports should be determined based on the pipe size, material, and the weight of the fluid it carries. Typically, the spacing ranges from 8 to 10 feet for horizontal pipes, but this can vary based on the specific conditions of the system.

Thermal Expansion

Piping systems are subject to thermal expansion and contraction, which can cause significant stress on the piping and support system. Therefore, it is essential to design the support system to accommodate these movements. This can be achieved using expansion joints or flexible supports, ensuring that the piping system can expand and contract without causing damage.

Vibration Control

Supports play a crucial role in minimizing the transmission of vibrations from the pump to the piping. This can be accomplished through the use of vibration isolators or damping materials. Proper vibration control not only enhances the performance of the piping system but also protects the integrity of the pump and other components.

Accessibility and Maintenance

A well-designed support system should facilitate easy access for maintenance and inspection of both the piping and the pump. This includes ensuring that access points are located in a convenient and safe manner, allowing for routine checks and repairs without unnecessary downtime.

Corrosion and Environmental Factors

The materials used for supports must be resistant to corrosion, especially in harsh environments. The impact of environmental factors such as temperature and humidity must also be considered to ensure the long-term durability of the support system. Proper selection of materials and regular maintenance can help extend the lifespan of the support system and enhance overall system performance.

Standards and Codes

Designing an effective pump piping support system requires adherence to industry standards and codes. Key organizations that provide these guidelines include the American National Standards Institute (ANSI) and the American Society of Mechanical Engineers (ASME). Compliance with these standards ensures not only the safety of the system but also its long-term reliability.

In conclusion, designing an effective pump piping support system requires careful consideration of various factors to ensure the integrity and performance of the piping system. Properly designed supports help prevent issues such as sagging, vibration, and misalignment, which can lead to inefficiencies, leaks, or even system failures. By following best practices in support design, users can optimize the performance and longevity of their pumping systems.
