WHAT TO LOOK FOR WHEN BUYING CAST IRON RAINWATER PRODUCTS

A rainwater pipe consists of a tube of cast iron with a socket at the top. Some sockets are plain, others have ears that allow for fixing the pipe to a surface.

Pipes should be straight with a consistent metal thickness. The external finish won’t necessarily be smooth like plastic due to the manufacturing process but should be even and without any obvious defects like cracking or uneven wall thickness. The inside of the pipe shouldn’t have any obstructions that could restrict the flow of water.

KYMetal round rainwater pipes are cast centrifugally with the socket cast on as an integral part of the pipe. It is a single piece of cast iron, and in our opinion is the best way to make round pipes. There are several advantages to this method of manufacture;
   Centrifugal casting is the only method of producing straight pipes with a consistent metal thickness and an even surface finish over the length of the pipe.
   Casting the socket on as part of the process, as opposed to attaching a separate socket to a pipe, ensures the integrity of the pipe and also ensures the internal flow is efficient and unobstructed.
