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.
When engineers become plumbers. What condition of chemical reaction is dissolving a cast iron pipe? I’m generally curious if this is accurate. Especially in over the counter products. A guess of mine is that the damage from chemical treatment of old metal pipes (including thinning copper drains) is caused more so by the expansion created when the chemical reaction heats up. And it does fast. This expansion can cause thining metal to crack.
Glass lining of cast iron tanks is a thing in the boiler industry.
i would guess that the corrosion and deteration of CI drainage systems you are referring too is more likely caused by old age. To prevent further deterioration where replacement isnt an option they can install a liquid liner that is more of an epoxy.
But like some else said. PVC or ABS.
would people a 100 years later think “people a hundred years ago glued plastic pipes using glue, and laid them in the ground. Now it has created more work for us to fix”
