Explanation: The primary purpose of rigid supports is to prevent vertical downward movement in piping systems and provide lateral support.
2. Characteristics of Rigid Supports
What characteristics do rigid supports possess according to the information provided?
Explanation: Rigid supports prevent vertical downward movement, may or may not prevent vertical upward movement, and allow for lateral movement and rotation.
3. Types of Rigid Supports
Which type of rigid support is designed to support two or more pipes?
Explanation: Trunnion supports are similar to dummy supports but are designed to support two or more pipes.
4. Applications of Rigid Supports
Where are rigid supports typically used according to the information provided?
Explanation: Rigid supports are typically used in areas where there is no need to allow for vertical thermal expansion or contraction and in piping systems subjected to high loads or in areas with a risk of fire or explosion.
5. Advantages of Rigid Supports
What is a notable advantage of rigid supports mentioned in the information?
Explanation: Rigid supports have the advantage of being simple to design and install.
6. Disadvantages of Rigid Supports
What is mentioned as a disadvantage of rigid supports in the information?
Explanation: Rigid supports can transmit vibration to connected equipment, which is mentioned as a disadvantage.
7. Selection of Rigid Supports
What factors influence the selection of the appropriate rigid support for a particular application?
Explanation: The selection of the appropriate rigid support depends on factors such as the weight, location, operating conditions, and type of piping system.
Short Article on Rigid Supports in Piping Systems
Rigid Supports
Rigid supports are a type of support used in piping systems to prevent vertical downward movement and to provide lateral support. They are typically used in situations where there is no need to allow for vertical thermal expansion or contraction. Rigid supports can be classified into two main categories:
- Shoe supports: These supports are typically used to support piping that is located on a floor or other flat surface. They are designed to carry the weight of the pipe and its contents and to prevent it from sagging.
- Hangers: These supports are typically used to support piping that is suspended from overhead structures. They are designed to carry the weight of the pipe and its contents and to prevent it from swinging or swaying.
Characteristics of Rigid Supports
Rigid supports have the following characteristics:
- They prevent vertical downward movement.
- They may or may not prevent vertical upward movement.
- They allow for lateral movement and rotation.
Types of Rigid Supports
There are several different types of rigid supports, including:
- Shoe supports: These supports are typically made of steel or concrete and are bolted to the floor or other supporting structure.
- Saddle supports: These supports are similar to shoe supports but are designed to support two or more pipes.
- Base plates: These supports are typically made of steel and are bolted to the floor or other supporting structure. They are designed to support large, heavy pipes.
- Dummy supports: These supports are typically made of steel and are welded to the pipe. They are used to provide lateral support and to prevent the pipe from vibrating.
- Trunnion supports: These supports are similar to dummy supports but are designed to support two or more pipes.
Applications of Rigid Supports
Rigid supports are typically used in the following applications:
- Piping systems that are located in areas where there is no need to allow for vertical thermal expansion or contraction.
- Piping systems that are subjected to high loads.
- Piping systems that are located in areas where there is a risk of fire or explosion.
Advantages of Rigid Supports
Rigid supports have the following advantages:
- They are simple to design and install.
- They are relatively inexpensive.
- They are very strong and durable.
Disadvantages of Rigid Supports
Rigid supports have the following disadvantages:
- They can transmit vibration to connected equipment.
- They can make it difficult to install and maintain piping systems.
Selection of Rigid Supports
The selection of the appropriate rigid support for a particular application depends on a number of factors, including:
- The type of piping system.
- The weight of the piping system.
- The location of the piping system.
- The operating conditions of the piping system.
Conclusion
Rigid supports are an important component of piping systems and can help to ensure the safety and reliability of these systems. When selecting rigid supports, it is important to consider the specific requirements of the application.
