Many modern drain cleaners, like Draino, contain harsh chemicals that can dissolve and corrode cast iron pipes over time, so is there a cast iron pipe that has a protective layer of glass on the inside? Glass sand can be applied to the cast iron, which is then heated that melts that glass, and rolled so that the melted glass coats evenly on the inside of the iron pipe. This glassy layer will protect against corrosive chemicals.

Thank you for your interest and attention.
