Product Overview

Description









* High-Impact Resistance
Ductile Iron Pipe has the high-impact strength and toughness to withstand shocks usually encountered in transportation, handling and installation.  

These characteristics also provide added security against stresses induced by water hammer, highway traffic and unexpected adverse forces.  Excellent impact resistance is confirmed by tests made in accordance with ISO2531.
* Conservation of Energy and Lower Pumping
Head losses in piping are directly related to inside diameters, and energy consumption and accompanying pumping costs are directly related to head losses.  

Therefore, the use of ductile iron piping having inside diameters greater than nominal can result in significant energy savings over the years.  In addition to helping keep operating costs and utility rates reasonable, this conservation of energy is also helpful to the environment.


* Superior Strength
Using a combination of chemical analysis and heat treatment to produce a pipe with desirable strength and ductility—a pipe that will withstand high internal pressure and deep cover—a pipe providing added reliability and safety for normal and unusual conditions, such as expansive soils and earth movement due to freezing and thawing.   
* Assured, Proven Long Life
Historical records document centuries of proven service of gray cast iron pipe.  Extensive laboratory and field tests under various installation conditions prove the soil corrosion resistance of ductile iron is as good, if not better than, grey cast iron.  The corrosion resistance of ductile iron pipe is verified by more than four decades of service.

Step. 1 GASKET INSERTION
The inside of sockets and the outside of spigots should be cleaned up to the insertion
depth. Gaskets should be wiped clean and inspected for damage. The gasket should then
be placed into the socket groove, rounded end entering first. Seating the gasket is made
easier by forming the gasket into a loop during insertion. The heel of the gasket should
fit uniformly into the retainer seat. On pipes larger than 12”, additional loops may help in
placing the gasket in the seating.




Step. 2 LUBRICATION
Ensure that the spigot end is properly chamfered or rounded to avoid tearing of the
gasket. Clean away all foreign matters from contact area of pipe. Apply a thin film of
recommended lubricant to the mating surface of the gasket. Avoid spray-on lubricants
as these may not provide enough lubrication. Avoid petroleum based lubricant as it may
damage the gaskets. Once lubricated, do not let lubricated area touch the ground or
other contaminant,
compromised seal could result.



  Step. 3 PIPE AND FITTING AND ASSEMBLY
Spigot should be inserted in socket. If socket is pushed, the gasket may be displaced.
Align and center the spigot in the socket and keep it in this position. Now gently push the spigot into the socket by suitable mechanical means, maintaining the alignment and level. A suitable gap should be left between the spigot end and the bottom of the socket to take care of any axial movement,deflection or temperature variation. To ensure this, two
band marks are made near the spigot end. These bands act as a ‘Go’ and ‘No-Go’ gauge. After jointing, the end of the socket must end between these two bands. If moderate force does not result in a solid seal, remove the pipe and inspect for foreign matters, improper
lubrication or misaligned gasket. Once you are certain of a solid seal, joint deflection can be applied within the permissible limits.



Step. 4 INSPECTION OF JOINT
Pipe that has been cut on site can easily be made ready for use by giving the plain end a bevel. With a portable grinder, create a 16° angle around the outside edge of the cut end. The edge of bevel and plain end of the pipe should be rounded off with the grinder.
Grinding should produce a bevel that continues back about 1” from the edge. This bevel will ease assembly and protect the gasket from damage by removing rough edges. Special consideration should be given to cutting pipe 14” or larger. In this case, pipe should be gauged full length.* Pipe that is gauged full length will be marked as such and conforms to ANSI/AWWA C151 Standard for Ductile Iron Pipe requiring spigot end factory gauging. To ensure tolerances, pipe for field cutting needs field gauging at the point of where the cut is to be made. Mechanical joint glands can be used for field gauging.
