12. Laying and installing ductile cast iron pipes

12.1 Importance of complying with installation rules

Laying and installing ductile cast-iron pipes is a straightforward operation. However, this does not mean that there are no rules to be observed during these operations. Methodical site organization, together with the use of trained and experienced personnel, is the key to success and rapid acceptance of the project at the end of installation. It also guarantees the durability of the pipes. The standard NF ISO 21051 has been established to communicate to all project stakeholders the essential rules that must be implemented.
