  1. What is the recommended minimum pitch (slope) for a steam supply main to ensure proper condensate drainage?

    Answer: 1/4 inch per foot in the direction of flow

    A slope of at least 1/4 inch per foot in the direction of steam flow allows condensate to drain toward drip legs and steam traps.

  2. Which ASME code governs the design and installation of power piping systems, including high-pressure steam piping in industrial plants?

    Answer: ASME B31.1

    ASME B31.1 (Power Piping) covers steam, water, and other piping used in electric power generating stations and industrial plants.

  3. A pipefitter is asked to install a 'drip leg' on a steam main. Where should it be located?

    Answer: At low points, ahead of control valves, and at end-of-main locations

    Drip legs are installed at low points and before equipment to collect and remove condensate before it can cause water hammer or equipment damage.

  4. When cutting stainless steel pipe with a grinder, why must stainless-steel-rated abrasive wheels be used?

    Answer: Carbon contamination from standard wheels can cause corrosion at the cut edge

    Standard abrasive wheels contain iron particles that embed in the cut edge, causing rust and undermining the corrosion resistance of stainless steel.

  5. What is the function of a pressure-reducing valve (PRV) in a steam distribution system?

    Answer: To reduce and regulate steam pressure to a lower, stable downstream pressure

    A PRV automatically reduces incoming high-pressure steam to a lower set pressure required by downstream equipment or systems.

  6. When welding chrome-moly (Cr-Mo) alloy steel pipe, what additional procedure is typically required that is not needed for carbon steel?

    Answer: Pre-heat and post-weld heat treatment (PWHT)

    Cr-Mo alloys require pre-heating to prevent hydrogen cracking and post-weld heat treatment (stress relief) to restore toughness and reduce residual stresses.

  7. A steamfitter notices a safety relief valve is 'simmering' (leaking slightly) below its set pressure. What is the correct action?

    Answer: Tag the valve out of service and replace it

    A simmering relief valve indicates a damaged seat or incorrect set point and must be replaced — attempting field repairs on safety valves is not permitted.
