Schedule 80 piping requirement

Schedule 80 piping requirement

• A. For all propane vapour regardless of pressure.
• B. For propane vapour under 125PSIG working pressure.
• C. For liquids only
• D. No schedule requirement applies

Answer: (B)

The idea being tested is how piping design and material selection depend on pressure in propane gas systems. Schedule 80 denotes a thicker-walled pipe with a higher pressure rating than the standard (Schedule 40). For propane vapour lines, many codes require Schedule 80 when the working pressure is at or below 125 psig. This thicker wall provides the needed strength and resistance to damage to keep the gas safely contained in the vapor phase. It isn’t required for all propane vapour blindly, and it isn’t about liquids only or about having no schedule requirement at all. When pressures exceed that level, a different, higher-rated or metal piping solution is typically used to maintain safety.
