Discussion Overview
The discussion revolves around calculating the minimum pipe wall thickness for a system conducting ethanol (both vapor and liquid) at varying pressures, specifically from 1 atm to 10^(-2) atm. The materials under consideration are copper and aluminum, and the context includes practical application in a semi-industrial setting.
Discussion Character
- Technical explanation
- Debate/contested
- Experimental/applied
Main Points Raised
- One participant inquires about the minimum pipe wall thickness needed for a pipe system handling ethanol at specified pressures, considering copper and aluminum as materials.
- Another participant references hoop stress and suggests that with a maximum differential pressure of about 1 bar, various materials could be used as long as they are compatible with ethanol.
- A different participant emphasizes the importance of adhering to applicable piping codes, specifically mentioning ASME B31.3 for the US, which directs to the BPV code for pressure vessel standards.
- One participant asks for guidance on where to obtain the ASME code, indicating a need for resources related to compliance.
- Another participant seeks clarification on the country of application and whether the project is industrial, highlighting the need for local code knowledge.
- A participant shares their background, noting they studied in the US but are currently working on a prototype project in India, raising questions about local regulations.
- One participant expresses uncertainty about Indian codes but suggests consulting with local engineers and discusses considerations for pipe diameter and pressure conditions.
Areas of Agreement / Disagreement
Participants express varying levels of familiarity with piping codes and regulations, particularly between the US and India. There is no consensus on the specific minimum wall thickness or the exact codes applicable to the project, indicating multiple competing views and unresolved questions.
Contextual Notes
Participants mention the need to consider local piping codes and regulations, which may vary significantly by country. There is also uncertainty regarding the specific conditions of the project, such as the diameter of the pipe and whether the pressure is strictly positive or includes vacuum conditions.
