Pipe Support Quiz

What is the function of a pipe support?

• A pipe support is a device that carries or supports the weight of a pipe and the fluid in the pipe over a specified length.

• A pipe support serves to guide, anchor, absorb or support a given load in order to maintain the integrity of the pipe work.

• Both of them above

• None of the above

Most pipe supports fall under the category of rigid supports!

• True

• False

Which of the following statements is true?

• A rigid pipe support is specifically suited to limit the movement of a pipe line in all directions.

• A rigid pipe support is specifically suited to limit the movement of a pipe line in at least one direction.

• A rigid pipe support is specifically suited to limit the movement of a pipe line in at least two directions.

• A rigid pipe support is not suited to limit the movement of a pipe line.

A dummy or trunnion support is a rigid support!

• True

• False

Which statement below is not correct?

• A dummy support consists of a tubular part, welded to the pipe, and not to the structure.

• A vertical pipe line is usually supported by two dummy supports resting on the structure.

• A vertical pipe line is always supported by one trunnion support resting on the structure.

• A dummy support is always welded to the structure.

What are Dynamically loaded supports?

• These pipe supports can work as either primary or secondary supports, providing variable resistance to movement based on compression and other variables.

• They are used to balance the concentrated gravitational load of pipe sections while allowing for thermal movement.

What are constantly loaded supports?

• Constant spring supports typically have the same designs and options as dynamically loaded supports.

• The supports are configured to maintain a static level of resistance rather than adjusting resistance based on load and

  other variables

• Both of them above

What are variable spring supports?

• Variables use coiled springs to support a load and allow movement

• They are used to balance the concentrated gravitational load of pipe sections while allowing for thermal movement

• The resistance of the coil to a load changes during compression like dynamic supports, which is why these devices are called VARIABLES

• All of them above

Which of the MSS standards describe supports?

• MSS-SP-53

• MSS-SP-58

• MSS-SP-88

• MSS-SP-96

MSS SP-58 has over 60 standard support types!

• true

• false
