1. What does a pipe support call out on an isometric drawing typically consist of?
Choose the correct description for a pipe support call out.
Explanation: A pipe support call out on an isometric drawing typically consists of letters and numbers indicating the type of support to be welded to the pipe.
2. What is the starting prefix for call outs of special pipe supports on isometric drawings?
Identify the correct starting prefix for special pipe support call outs.
Explanation: Special pipe supports on isometric drawings have a starting prefix of “SPS” in their call outs.
3. Where are support call outs typically placed on an isometric drawing?
Choose the correct location for placing support call outs.
Explanation: Support call outs are typically placed near the pipe on the isometric drawing for clear representation.
4. What information may a single support call out represent?
Identify the correct statement about a single support call out.
Explanation: A single support call out may represent a combination of standard support types, such as clamps and wear pads.
5. How are special pipe supports indicated on an isometric drawing?
Choose the correct statement about the representation of special pipe supports.
Explanation: Special pipe supports are indicated with a separate “SPS” call out on the isometric drawing.
6. How are multiple pipes on a single support frame represented on isometric drawings?
Choose the correct statement about representing multiple pipes on a single support frame.
Explanation: If a single support frame supports multiple pipes, the call out is shown on only one isometric drawing, referencing others affected.
7. What are the benefits of clear pipe support call outs on isometric drawings?
Identify the correct statements about the benefits of clear call outs.
Explanation: Clear pipe support call outs ensure accurate interpretation during fabrication and installation, facilitate communication, and provide a clear reference point for future maintenance and inspection of the piping system.

Understanding Pipe Support Call Outs in Isometric Drawings
Pipe supports play a crucial role in piping systems, and their accurate representation on isometric drawings is essential for proper installation and maintenance. Here’s a breakdown of how pipe supports are typically shown in these drawings:
Pipe Support Call Out:
- Represented by a combination of letters and numbers.
- Indicates the type of support to be welded to the pipe.
- Standard support types like clamps, shoes, and trunnions have specific call out codes.
- Special pipe supports have unique call outs starting with “SPS” (Special Pipe Support).
Location and Combination:
- Support call outs are placed near the pipe on the isometric drawing.
- A single call out may represent a combination of standard support types.
- For example, a call out might include both a clamp and a wear pad.
Special Pipe Supports:
- Indicated with a separate “SPS” call out on the isometric drawing.
- Detailed information, including individual components, is provided on a dedicated special pipe support drawing.
- No support components are listed on the isometric drawing for special supports.
Multiple Pipes on a Single Support Frame:
- If a single support frame supports multiple pipes, the call out is only shown on one isometric drawing.
- For other affected lines, the drawing references the isometric drawing with the original call out.
Benefits of Clear Call Outs:
- Ensures accurate interpretation of support requirements during fabrication and installation.
- Facilitates easier communication and coordination between engineers, fabricators, and installers.
- Provides a clear reference point for future maintenance and inspection of the piping system.
Additional Notes:
- Isometric drawing standards and conventions may vary depending on industry regulations and project specifications.
- Consulting project-specific drawings and documentation is crucial for ensuring accurate interpretation of pipe support call outs.
By understanding how pipe supports are shown in isometric drawings, you can effectively interpret piping designs and ensure the successful implementation and maintenance of piping systems.
