1.17  Working safely with cast iron products on steam

Cast iron products are commonly found on steam and condensate systems. If installed correctly 

using good steam engineering practices, it is perfectly safe. 

However, because of its mechanical properties, it is less forgiving compared to other materials 

such as SG iron or carbon steel. 

The following are the good engineering practices required to prevent waterhammer and ensure 

safe working conditions on a steam system.

Safe Handling

Cast Iron is a brittle material. If the 

product is dropped during installation 

and there is any risk of damage the 

product should not be used unless it 

is fully inspected and pressure tested 

by the manufacturer. 

Please remove label before 

commissioning.
