Because early equipment was designed to install cable and small-diameter pipe, HDD technology wasn't initially considered as an option for installing ductile
The presenters also discussed special applications of ductile
iron, including austempered, high silicon molybdenum and compacted graphite iron.

About DIPRA: The Ductile
Iron Pipe Research Association provides accurate, reliable engineering information about ductile
iron pipe to a wide variety of utility and consulting engineers.
3% SiC to the base iron was the most efficient metallurgical additive for increasing the nucleation potential (nodule count) in ductile
iron, reducing under-cooling tendency and upgrading tensile properties, primarily percent elongation.
In addition, says Carpenter, ductile
iron pipe is just as suitable for installation by directional drilling and pipebursting procedures as is HDPE and PVC pipe, and in some respects may be even better suited for trenchless installations than plastic materials.
Duncan Frazer, CEO of FT Ductile
Ltd, commented: "It is necessary that pipe networks are made as resistant as possible to reduce the necessity for regular pipe maintenance in the future.
The transaction will see Wescast acquire 100% of Georgia Ductile
for approximately $70 million (US).
13, 2012 /PRNewswire/ -- Ductile
iron pipe, the durable and environmentally friendly choice for water utilities around the world, earned the coveted SMaRT (c) Sustainable Product Certification, an independent rating system for the sustainability of a product throughout its life cycle, the Ductile
Iron Pipe Research Association (DIPRA) announced today.
During this $254,000 project, PSW replaced six-inch cement main with eight-inch ductile
iron main on 9th Street between Simpson Avenue and the Ridley Creek.
This effort involves using modern designs when installing water and wastewater pipelines and ductile
iron pipe will be a major component.
When welded, ductile
iron is liquefied in the welded area and may solidify with a carbidic structure in the fusion zone that limits the toughness of the weldment.
DIS concentrates its efforts on ductile
iron technology pertaining to production, properties and applications.
