Section of DICL pipe (ductile iron concrete lined), commonly used for utility water mains, showing iron casing, concrete lining, and textured polymer protective coatings on the inner and outer surfaces. Ductile iron pipe is pipe made of ductile cast iron commonly used for potable water transmission and distribution. [1]
Cement-mortar lined ductile iron pipe is a ductile iron pipe with cement lining on the inside surface, and is commonly used for water distribution. Cement-mortar lined ductile iron pipe is governed by standards set forth by DIPRA ( Ductile Iron Pipe Research Association ), and was first used in 1922 in Charleston, South Carolina .
Ductile iron is used in many piano harps (the iron plates which anchor piano strings). Ductile iron is used for vises. Previously, regular cast iron or steel was commonly used. The properties of ductile iron make it a significant upgrade in strength and durability from cast iron without having to use steel, which is expensive and has poor ...
Austempered Ductile Iron (ADI) is a form of ductile iron that enjoys high strength and ductility as a result of its microstructure controlled through heat treatment. While conventional ductile iron was discovered in 1943 and the austempering process had been around since the 1930s, the combination of the two technologies was not commercialized ...
Meehanite is a trademark for an engineering process to make a range of cast irons produced under specific and carefully controlled conditions to precise internationally recognized specifications. According to the Meehanite Worldwide company, when correctly followed the Meehanite process will produce cast iron with uniform soundness, consistent ...
Ductile iron pipe for waste water have an internal lining made of calcium aluminate cement mortar. Concrete pipes for sewerage can be made either with full mass calcium aluminate cement concrete or with an internal liner of calcium aluminate cement mortar.
Iron based piping is subject to corrosion if used within a highly oxygenated water stream. [7] Aluminum pipe or tubing may be utilized where iron is incompatible with the service fluid or where weight is a concern; aluminum is also used for heat transfer tubing such as in refrigerant systems.
