✍️ Sample SPED Questions & Answers
1. MSS SP-69 serves what purpose in the context of pipe support engineering?
MSS SP-69 (Pipe Hangers and Supports — Selection and Application) guides engineers in matching the appropriate support type (hanger, rest, guide, anchor, etc.) to specific piping conditions and service requirements.
2. What is the primary advantage of using Alloy 625 (Inconel 625) for piping in offshore subsea applications?
Alloy 625's high molybdenum (≈9%) and chromium (≈22%) content give it exceptional resistance to seawater pitting and crevice corrosion in subsea environments.
3. What does 'parametric modeling' mean in the context of 3D piping design?
Parametric modeling links geometry to parameters (diameter, length, rating) so changing a value automatically updates all related geometry.
4. What is the purpose of a 'golden weld' or 'tie-in weld' lock-out procedure during pressure testing?
Tie-in weld isolation procedures ensure that pressurized test sections are physically separated from adjacent piping not yet constructed or cleared for testing.
5. What is 'cathodic protection' and when is it required for piping systems?
Cathodic protection impresses an electric current or uses sacrificial anodes to prevent electrochemical corrosion of buried or submerged steel piping.
6. When applying the Bernoulli equation between two points in a real piping system, which additional term must be included?
The extended Bernoulli equation includes a head loss term hL (friction + minor losses) to account for energy dissipation: P₁/γ + V₁²/2g + Z₁ = P₂/γ + V₂²/2g + Z₂ + hL.
