What is the maximum service temperature for Ductile Iron pipe?
The maximum service temperature for Ductile Iron pipe is dependent on the type of elastomers used for gaskets, joint configurations, and linings utilized rather than the iron. Generally, the maximum service temperature for Ductile Iron pipe gaskets is 120°F to 300°F, depending on the type of elastomer and joint configuration. Standard SBR gaskets are generally rated up to 150°F for push-on joints and 120°F for mechanical joints. The maximum service temperature for linings used for Ductile Iron pipe is generally 120°F to 212°F. Seal-coated cement-mortar linings are rated for 150°F, and non-sealcoated cement-mortar linings are rated for 212°F. For service temperatures greater than those above, consult the pipe manufacturer for specific recommendations. For gasket and lining data sheets, which include maximum service temperatures, contact DIPRA.
