Can pipe previously used for natural gas be repurposed for propane?

The correct answer indicates that pipe previously used for natural gas can indeed be repurposed for propane after it has been properly cleaned. This is based on the similarities in physical and chemical properties between natural gas and propane, which allows for the use of the same materials for both gases. However, because these gases can have different pressures and combustion characteristics, thorough cleaning is crucial to remove any residue or contaminants that could affect the performance or safety of the system when propane is used.

Choosing this option reflects an understanding of proper maintenance and safety protocols in the gas industry. It also emphasizes the importance of ensuring that any equipment used is free from remnants that could lead to issues when transitioning fuels. This process can ensure the safe and efficient operation of the propane system while maintaining compliance with regulations that govern gas piping materials and maintenance practices.
