1. Vertical Clearances for Supports

What should supports be designed to provide regarding vertical clearances between finished grade and the bottom of piping, insulation, or support bar?

A) 1 meter vertically
B) 2 meters vertically
C) 3 meters vertically
D) Depends on specific approval

Show Answer

Explanation: Supports should be designed to provide specific vertical clearances between finished grade and the bottom of piping, insulation, or support bar, considering potential obstructions.

2. Crane Access & Tube Bundle Pulling

How should equipment and structures be arranged to permit crane access to service air coolers, compressors, and exchangers?

A) Provide underground access
B) Jack out tube bundles against the shell
C) Install dropouts for exchangers at elevated structures
D) None of the above

Show Answer

Explanation: Equipment and structures should be arranged to permit crane access, and exchanger tube bundles should be “jacked out” against the shell.

3. Access to Pumps

What clear access dimensions are recommended centrally under main pipe ways for small mobile equipment to service pumps/motors?

A) 2m vertically and 1m horizontally
B) 3m vertically and 2m horizontally
C) 4m vertically and 3m horizontally
D) 5m vertically and 4m horizontally

Show Answer

Explanation: Clear access of 4m vertically and 3m horizontally shall be provided centrally under main pipe ways for small mobile equipment to service pumps/motors.

4. Access to Lower Items to Grade (Lowering Area)

What clear access shall be provided at grade on the access side for lowering external & internal fittings, PSVs, control valves, etc., from elevated equipment/structure?

A) 1m vertically and 0.5m horizontally
B) 2m vertically and 1m horizontally
C) 3m vertically and 2m horizontally
D) 4m vertically and 3m horizontally

Show Answer

Explanation: Clear access shall be provided at grade on the access side for lowering external & internal fittings, PSVs, control valves, etc., from elevated equipment/structure.

5. Lighting and Obstruction Consideration

What should be considered when designing vertical clearances for supports according to Clearances in Layout?

A) Wind load calculations
B) Lighting or any other potential obstruction
C) Temperature variations
D) Material specifications

Show Answer

Explanation: When designing vertical clearances for supports, consideration shall be given to lighting or any other potential obstruction which may hang below bottom levels of structural supports.

6. Crane Access for Lowering Equipment

What should be considered when arranging equipment and structure to permit crane access for lowering equipment?

A) Wind direction
B) Accessibility for maintenance
C) Equipment color
D) None of the above

Show Answer

Explanation: Equipment and structure should be arranged to permit crane access for lowering equipment, considering accessibility for maintenance.

7. Tube Bundle Removal Space

What space should be provided for tube bundle removal according to Clearances in Layout?

A) Restricted area
B) Clear space
C) Buffer zone
D) No specific space required

Show Answer

Explanation: A clear space for tube bundle removal shall be provided according to Clearances in Layout.
