1 SECION 12 MERICN Historical Data

2 MERICN Historical Data Obsolete Piping Materials Cast iron pipe will often last for centuries. One evidence of this is the world s oldest known cast iron water mains which were installed to supply water to the town and parks of Versailles, France. his pipe provided continuous service for more than 00 years. However, changing requirements and improved manufacturing techniques have resulted in some piping materials becoming obsolete. lthough no longer manufactured, many piping materials continue in service, such as cast iron pipe with caulked bell and spigot joints which was one of the earliest types of joints used for underground service. Over the years MERICN furnished millions of feet of gray cast iron pipe in sizes 2" through 48"; however, ductile iron has replaced gray iron in all of the pipe and fittings now being manufactured. In ductile iron, like in gray cast iron, MERICN has continued to make improvements in joints and configurations, eliminating some joints in the process. his section is included to furnish limited information pertaining to some of these obsolete materials. Contact MERI- CN for additional information if needed. Note: When connecting to or repairing existing pipelines, it is good practice to carefully examine/measure the items involved prior to procuring materials and prior to commencing labor- and equipmentintensive operations. his would require at least minimal exposure of existing buried pipelines for identification and measurement. Likewise, all OSH and other safety and governmental regulations should be complied with in such operations. MERICN HISORICL D OBSOLEE PIPING MERILS Cast Iron Pipe being replaced by a larger main is taken up after years of service for installation in another location for continued service. 12-1
