Ductile Iron Pipe Guidelines Technical PublicationsDuctile Iron pipe manufacturers have been successfully welding Ductile Iron pipe for many years and should be consulted on their recommendations for field welding and torch cutting their product. This manual is intended as a guide for field welding and cutting cement-mortar-lined and unlined Ductile Iron pipe.

Ductile Iron Pipe Pipe Research A-12 Association

In 1987 DIPRA conducted similar tests that clearly showed the direct tapping superiority of Ductile Iron over pvc pipe. Since those first two groups of tests were run, pressure classes of Ductile Iron have been introduced. Thus, to update data from the previous testing and to validate the established confidence in Ductile Iron pipe, DIPRA Ductile-Iron Pipe and Fittings downloadDuctile-Iron Pipe and Fittings . An indispensable reference for water distribution systems designers, managers, contractors, and operators, this Third Edition provides the most current specifications for ductile-iron pipe and fittings. This peer-reviewed manual offers complete technical and applications information about this versatile and Ductile-Iron Pipe and FittingsA more detailed description of the joints used with ductile-iron pipe is found in chapter 5 of this manual. 1.1.3 Development of Ductile-Iron Pipe The advent of ductile-iron pipe in 1948 was one of the most significant developments in the pressure pipe industry. Quickly recognized as a pipe

Can I direct tap a Ductile Iron fitting? Yes, you can. Ductile Iron pipe and fittings can be direct tapped for air release valves, sampling ports, service connections, etc. You do want to ensure that there is adequate thread engagement to provide both strength and a leak-free seal. Testing has shown that, with the use of a good thread sealant INSTALLATION GUIDE FOR DUCTILE IRON PIPEreasons, Ductile Iron is an ideal material for transporting water and other liquids. Proper installation procedures will add immeasurably to the long and useful life of Ductile Iron pipe.

TAPPING DUCTIL E IRON PIPE

TAPPING DUCTIL E IRON PIPE 866.DIP.PIPE 2006 EDITION P 5 U.S. PIPE AND FOUNDRY CO. TAPPING DUCTILE IRON PIPE BRO-035 REVISED 12.06 NSF ® Certified to ANSI/NSF 61 Tests performed by the Ductile Iron Pipe Research Association prove that .25" wall Ductile Iron pipe can be tapped with 3/4" or 1" service taps without using tapping saddles. Tapping What is the Maximum Direct Tap Size for Ductile Iron Pipe With Ductile iron pipe (DI pipe), typical service taps can be installed directly into the wall of the pipe, which is called direct tapping.. The ability to use direct tapping eliminates the need for tapping saddles. And the ease at which DI pipe can be "hot tapped" helps avoid the issue of unhappy consumers because their service and pressure are not impacted by the addition of a new tap. Why Should I Use Ductile Iron Pipe? Four Key If you do, ductile iron pipe will save you operating costs in several ways including pumping costs, tapping costs, and possible damage from other construction, causing failure and the cost to repair in general. On pumping costs, ductile iron pipe is more energy efficient than other competing pipeline materials due to its oversized inside
