Description
Cast-iron pipes are usually unprotected.
General Liable to breakage by rough handling. Pipes with a bell or flange end are most often broken or cracked on the straight or spigot end, and, when this occurs, the damaged portion may be cut off and sold as scrap while the remainder of the pipes may be salved as sound short lengths. Spun cast-iron pipes are quite easily cut with a cold chisel.
An investigation into the cause of unexplained hairline cracks in centrifugally spun cast-iron pipes showed that they were due to the cooling process. The pipes being laid on the open ground while still warm, and contact of one section of the pipe with the cold earth caused uneven cooling resulting in the hairline splitting observed at destination.
