SPED Piping Design Principles & Standards 2

Question 1

Which ASME code governs the design of process piping in industrial facilities?

Accepted Answer

ASME B31.3

Answer

ASME B31.3 is the Process Piping code that governs chemical, petroleum, and other process plant piping systems.

Question 2

What is the purpose of a spectacle blind (figure-8 blind) in piping systems?

Accepted Answer

To allow full flow or complete isolation by rotating the blind

Answer

A spectacle blind provides a visual indication of line status and allows operators to switch between full flow and complete isolation by rotating the figure-8 plate.

Question 3

In piping isometrics, what does the abbreviation 'BOP' stand for?

Accepted Answer

Bottom of Pipe

Answer

BOP stands for Bottom of Pipe and is used as a reference elevation datum for pipe routing and support design.

Question 4

What is the minimum clearance typically required between insulated pipe surfaces and structural steel per standard practice?

Accepted Answer

3 inches

Answer

Standard practice requires a minimum 3-inch clearance between insulated pipe surfaces and structural members to allow for insulation installation and maintenance.

Question 5

Which type of valve is best suited for throttling service in process piping?

Accepted Answer

Globe valve

Answer

Globe valves are specifically designed for throttling service because their disc and seat configuration allows precise flow regulation.
