Thank you for watching. This is the final episode of our three-part series on snow melting pipe maintenance for a private retail store in Nagaoka City. Our secret to tackling complex piping was a new method called "Horn Pipe Core Drilling." Unlike traditional core drilling, which cuts through the surrounding concrete, this method directly bores into the horn pipe that extends as an extension of the riser pipe. It allows for smoother cleaning and sludge removal but is a delicate and difficult method where even a slight angle mistake can lead to significant replacement work. Join us for the final sprint of this project, where we'll be dealing with a mountain of limescale! Be sure to watch!
