How to choose the right thermal pipe support?

Choosing the right thermal pipe support is essential for maintaining the integrity and efficiency of piping systems in various industrial settings. This guide aims to provide you with comprehensive statistics and insights to help you make informed decisions regarding thermal pipe supports.

The Importance of Thermal Pipe Supports

Thermal pipe supports provide a stable foundation for pipes while allowing for thermal expansion and contraction. The right support minimizes stress on the piping, reducing the risk of leaks and failures. According to a study by the American Society of Mechanical Engineers (ASME), improperly supported piping can lead to a 30% increase in maintenance costs over the lifespan of the pipes.

Key Factors in Choosing Thermal Pipe Supports

When selecting thermal pipe supports, consider the following key factors:

1. Type of Pipe Material

The material of the pipe plays a crucial role in the type of support required. For instance, a 2019 report by the National Association of Corrosion Engineers found that carbon steel pipes require supports that can accommodate corrosion, whereas PVC pipes require supports designed to handle thermal expansion.

2. Temperature and Pressure Conditions

Understand the thermal and pressure conditions which the pipes will operate under. The International Association of Plumbing and Mechanical Officials (IAPMO) states that pipe supports must be chosen based on the maximum operating temperature. For example, supports for high-temperature applications (above 400°F) should be made with materials that can withstand these conditions without deforming.

3. Load Bearing Capacity

Understanding the weight of the pipe and its contents is crucial for selecting supports. According to Piping Design and Engineering by T. S. S. W. R. Heru, the load-bearing capacity should be calculated based on the full weight of the pipe when filled with fluid, including additional weights of insulation and any fixtures installed. Typically, supports should have a rating that exceeds the calculated load by at least 20% to ensure durability.

4. Flexibility and Movement

Pipes expand and contract with temperature changes. As supported by a study published in the Journal of Constructional Steel Research, thermal pipe supports should allow for axial and lateral movements while still adequately supporting the pipe. Supports must include features like slide plates and spring hangers for better adaptability.

Common Types of Thermal Pipe Supports

Here are some commonly used types of thermal pipe supports, each suited for specific applications:

1. Hangers

Pipe hangers are widely used and essential for the vertical support of piping systems. The support industry reports indicate that 85% of piping systems utilize some form of hanger to maintain an elevated position, with varying designs suited for different load requirements.

2. Supports and Stands

Concrete or steel supports and stands are employed where pipes run horizontally and encounter heavier loads. The installation of these supports can reduce the chances of sagging, as noted by the American Institute of Steel Construction.

3. Clamps

Piping clamps can secure pipes tightly against structural elements, allowing for less movement in small bore pipes. Surveys conducted by the Piping and Equipment Suppliers Association show that using clamps can lead to a reduction in misalignment by up to 40% during installation.

Best Practices in Selection and Installation

To ensure the longevity and reliability of thermal pipe supports:

• Conduct regular assessments of support conditions and pipe integrity.
• Utilize appropriate materials that offer resistance to environmental conditions, such as moisture and chemicals.
• Follow manufacturer guidelines based on specific load and environmental requirements.

Conclusion

Choosing the right thermal pipe support involves thorough understanding of the pipe materials, temperature conditions, load requirements, and movement allowances. With proper selection and installation, industrial operators can minimize maintenance costs and ensure the longevity of their piping systems.
